GS Paper: GS3

  • Why companies are adopting sustainable business models?

    The article discusses the three undercurrents that are pushing companies to adopt more sustainable business models.

    Demand for sustainable business practices

    • Companies across the world are facing pressure to adopt sustainable business practices.
    • In a global first, a judicial court in the Netherlands has invoked the principles of human rights obligations of companies to rule that the Royal Dutch Shell will have to further accelerate its targeted reduction in greenhouse gas (GHG) emission.
    •  The shareholders of Chevron forced upon the management a resolution to set strict emission targets from the products that it sells.
    • The German cabinet approved a law that requires all coal-fired plants to close down much earlier than the target date set only eighteen months ago.
    • In India, the SEBI came out with a new set of Business Responsibility and Sustainability Reporting (BRSR).
    • BRSR will be mandatory for the top 1,000 companies from the next year.

    Three factors driving the change

    1) Investors’ pull

    • Workers saving for their pension do not want their investments to go to companies whose tailings-dam can burst and cause hundreds of death in Brazil.
    • Investors also realise the long-term business risk of companies if sustainability isn’t a focus.

    2) Governments’/regulators’ push

    • In 2021, the US announced that it will cut emissions by over 50% by 2030.
    • Japan has almost doubled its 2030 targets.
    • The UK has now announced a target to cut 40-45% by the same time, from the earlier goal of a 30%-cut.
    • China has announced that its emissions will peak by 2030, and by 2060, it would have net zero emissions.
    • India is expected by the global community to announce net-zero by 2050.
    • All of these have huge implications not only for hydrocarbon companies but across multiple sectors.
    • Banking regulators are asking banks to include climate in the risk assessment of the companies they lend to.
    • Insurance and pension regulators are raising similar questions in their sector.

    3) Measurement/reporting

    • When sustainability debates picked up, many organisations like CDP, CDSB, PRI, GRI, TCFD, IMP, IIRC, SASB, etc, sprang up to fulfill the need for sustainability reporting.
    • Often, these worked at cross purposes and in competition with each other, leading to ‘greenwashing’ and other malpractices and creating confusion in the minds of investors.
    • But, the realisation that the investors need a set of comparable and verifiable reporting formats has gathered momentum in the past one year.
    • The last excuse to avoid focus on sustainable business practices will also wither away.

    Consider the question “Financial capital is just one of the multiple capitals a successful company must possess. This brings sustainability into the focus. In light of this, discuss the factors that are forcing the companies to factor in the sustainability in their business models.”

    Conclusion

    The decades-old debate on environmental damage and sustainability is now reaching a decisive phase. Companies need to factor in the sustainability aspect in their profit calculus to remain relevant in changing world.

  • What Centre must do to meet the economic challenges

    The article takes an overview of the fiscal and monetary challenges posed by the second covid wave and suggest ensuring the availability of liquidity.

    GDP projections need to be re-examined

    •  According to NSO’s provisional estimates for 2020-21, the annual contraction in real GDP turned out to be 7.3 per cent.
    • The erstwhile GDP growth projections for 2021-22 are being re-examined to take into account the adverse impact of the second wave of the pandemic.
    • The RBI has revised down its 2021-22 real GDP growth forecast to 9.5 per cent.
    • Some other recent estimates (ICRA) indicate the feasibility of a 9 per cent growth.
    •  It is also important to consider nominal GDP growth for 2021-22 since that would be a critical determinant of fiscal prospects. 
    • In the light of supply-side and cost-push pressures, the RBI has projected CPI inflation at 5.1 per cent.
    • The nominal GDP growth may be projected at 13.4 per cent, that is, 1 percentage point lower than Centre’s budget assumption of 14.4 per cent.

    Fiscal aggregates

    • The Controller General of Accounts’ data indicate a gross tax revenues (GTR) of Rs 20.2 lakh crore and net tax revenue of Rs 14.2 lakh crore for 2020-21. 
    • The likely growth in GTR for 2021-22 may be derived by applying a buoyancy of 0.9.
    • This gives a tax revenue growth of 12 per cent, translating that to projected gross and net tax revenues for 2021-22 would mean Rs 22.7 lakh crore and Rs 15.8 lakh crore respectively. 
    • This implies some additional net tax revenues to the Centre amounting to Rs 0.35 lakh crore as compared to the budgeted magnitudes.
    • The main expected shortfall may still be in non-tax revenues and non-debt capital receipts.
    • According to the CGA numbers, their 2020-21 levels are respectively Rs 2.1 lakh crore and Rs 0.57 lakh crore.
    • Applying a growth rate of 15 per cent on these, a shortfall in 2021-22 to the tune of Rs 1.3 lakh crore may arise in non-tax revenues and non-debt capital receipts.

    So, how much would be the Fiscal Deficit?

    • The growth rates of non-tax revenues and and non-debt capital receipts average to a little lower than 15 per cent during the five years preceding 2020-21.
    • In any case, the large budgeted growth of 304 per cent in non-debt capital receipts for 2021-22 seems quite unlikely because of the challenges posed by the second wave.
    • Taking into account RBI’s recently announced dividend of Rs 0.99 lakh crore to the Centre, the main shortfall may be in non-debt capital receipts.
    • Together, the overall shortfall in total non-debt receipts may be limited to about Rs 0.9 lakh crore, or 0.4 per cent of estimated nominal GDP.
    • This indicates that a slippage, if any, in the budgeted fiscal deficit of 6.7 per cent of GDP, as revised in view of the recently released GDP data, could be a limited one.

    Way forward: Prioritise three heads

    • First, an increase in the provision for income support measures for the vulnerable rural and urban population.
    • Second, in light of the recent decision, the budgeted expenditure on vaccination of Rs 0.35 lakh crore ought to be augmented, at the very least, doubled.
    • Third, additional capital expenditure for select sectors, particularly healthcare, should also be provided for.
    • Together these additional expenditures would amount to Rs 1.7 lakh crore, about 0.8 per cent of the estimated nominal GDP.
    • Thus, we need to plan for a fiscal deficit of about 7.9 per cent of GDP.

    Borrowing programme would need RBIs support

    • The Centre has announced borrowings of Rs 1.6 lakh crore to meet the shortfall in the GST compensation cess.
    • Given the higher fiscal deficit, it would need to add to its borrowing programme another Rs 2.6 lakh crore, taking the total borrowing, including GST compensation, to about Rs 16.3 lakh crore, from Rs 12.05 lakh crore now.
    • Borrowing by states would be in addition to this.
    • The net result will be an unprecedented borrowing programme by the Centre which may require RBI’s support.
    • RBI is injecting liquidity into the system through various channels.
    • Banks have sufficient liquidity to subscribe to new debt.
    • This is indirect monetisation of debt.
    • This is not new, but the scale is much higher.
    • Direct monetisation is best avoided.
    • The success of the borrowing programme of the Centre depends on the support provided by the RBI.
    • The support need not be direct.
    • It can be indirect as is currently happening. RBI is injecting liquidity into the system in a big way.
    • Despite this, the money multiplier is low.
    • This may be attributed to two reasons: Low credit expansion and larger leakage in the form of currency.
    • The potential for money supply growth is large.
    • The discussion in the monetary policy statement on inflation is focused entirely on supply availability and bottlenecks in the distribution of commodities.
    • The output gap is certainly relevant.
    • But equally relevant in an analysis of inflation is liquidity in the system, and its impact on output and prices with lags.
    • The injection of liquidity has its limits.

    Conclusion

    With higher expenditure, financed through borrowings, the impact of liquidity expansion on inflation needs to be monitored.

  • Issues with special treatment of states with higher contribution to GST pool

    The article highlights the issues with the demand for special treatment of states with higher contribution to GST pool.

    Debate on GST

    • The issue of GST concessions on COVID relief has brought into focus the structural flaws in the GST structure.
    • In this process, the structure and design of GST — essentially a tax on consumption — is being questioned.
    • The issue of  “rich” states versus “poor” ones, the decision-making process in the GST Council, and the representation of various states in the Council have also come into the focus.

    Why States should be treated equally in GST Council

    1) Consensus on GST

    • The structure and design of GST and its basic features, as enshrined in the 101st Constitution Amendment Act, were unanimously adopted and endorsed by Parliament.
    • The broader and finer points of the law, were thoroughly discussed and debated and recommended by the GST Council after a complete consensus.
    • These were further debated and approved by not only Parliament but also by each of the state legislatures.
    • There was complete consensus even on the issue of delegated legislation — something unheard of in a federal environment.

    2) Equality of all states

    • In this process of consensus building, no state was accorded even the slightest of special privilege.
    • That is why the consensus surrounding GST was unprecedented whether in India or any other federation.
    • Therefore, arguing for special treatment of some states is a dangerous idea, particularly in governance, and more so in a welfare state.
    • For, this would open the gates for elitist arguments such as special rights for bigger taxpayers, unequal voting rights in elections and preferential treatment for a select few.

    3) Issues with greater contribution to GST revenue pool

    • It is not correct to argue that the GST collected in a state represents the revenue of that particular state for, under the GST mechanism, the tax deposited by a taxpayer in a state is a function of largely the value of supplies made by such taxpayer.
    • Approximately 50 per cent at the aggregate level and much higher at the state level of such values are of an inter-state nature.
    • In other words, most supplies made from any producing state are consumed elsewhere and the revenue in such a situation naturally and rightfully accrues to the destination state.

    4) No transfers based on a formula

    • It is equally fallacious to argue that under GST, most of the revenue is collected by the Union and is transferred to the states on the basis of some formula.
    • The quantum of IGST revenue that is settled to any state is directly related to the returns filed in that state and the cross utilisation of credit exhibited in such returns; part of this settlement also comprises tax on supplies destined to that state, as exhibited in the returns of such suppliers.
    • There is no “formula” as such for “transfer” of revenue collected by the Centre. Instead, such “transfers” are directly relatable to the consumption (whether intermediate or final) in any state.

    5) Locational or geographical advantage

    • There is another dimension to the higher revenue collection in a few states.
    • One may note that such states enjoy locational or geographical advantages, being mostly coastal and immensely suited to the needs of trade and distribution as also manufacturing.
    • Also, the disadvantage to such states on account of lower availability of certain vital minerals like coal and iron ore was undone by the principle of freight equalisation resorted to in the years following Independence.
    • This contributed, in no small measure, to the development of such states.

    6) Unequal transfers of Central receipts

    • The argument of unequal transfers of central receipts also does not hold water, either in India or in any other federation.
    • As is well known, such transfers are intended for correcting horizontal fiscal imbalances in a federation.

    Conclusion

    We should thus concentrate on carrying forward the glorious traditions of perhaps the only institution of co-operative federalism that we have been able to build so far.

  • Beed Model of Crop Insurance in Maharashtra

    Maharashtra CM has urged the Prime Minister for state-wide implementation of the ‘Beed model’ of the crop insurance scheme Pradhan Mantri Fasal Bhima Yojana (PMFBY).

    Consider this question:

    Q.Payouts released often exceed the premium collected in PMFBY. Discuss this limitation of the PMFBY where insurance firms refuse to bid in drought prone regions.

    What is PMFBY?

    • Launched in 2016, the flagship PMFBY insures farm losses against inclement weather events.
    • Farmers pay 1.5-2% of the premium with the rest borne by the state and central governments.
    • It is a central scheme implemented by state agriculture departments as per central guidelines.
    • For farmers, the low rate of premium and relatively decent coverage make the scheme attractive.
    • Prior to 2020, the scheme was optional for farmers who did not have loans pending, but mandatory for loanee farmers.
    • Since 2020, it has been optional for all farmers. In Maharashtra, over the years, more non-loanee farmers have enrolled, although it was optional for them.

    Issues faced in Maharashtra

    • Voices were raised in Maharashtra about the need to change the scheme.
    • Delay in claim settlement, failure to recognize localized weather events, and stringent conditions for claims were among the concerns. Another complaint was about alleged profiteering by insurance companies.
    • For Maharashtra, where farmers predominantly depend of monsoon rains to water their crops, the scheme soon turned out to be non-profitable for insurance companies given the high payments they had to make.
    • Payouts were close to or exceeded the premium collected in some years, leading to losses to insurance companies.

    What is Beed model the state government wants implemented?

    • Located in the drought-prone Marathwada region, the district of Beed presents a challenge for any insurance company.
    • During the 2020 kharif season, tenders for implementation did not attract any bids. So, the state Agriculture Department decided to tweak the guidelines for the district.
    • The state-run Indian Agricultural Insurance Company implemented the scheme.
    • Under the new guidelines, the insurance company provided a cover of 110% of the premium collected, with caveats.
    • If the compensation exceeded the cover provided, the state government would pay the bridge amount.
    • If the compensation was less than the premium collected, the insurance company would keep 20% of the amount as handling charges and reimburse the rest to the state government.

    Greater role for States

    • In a normal season where farmers report minimal losses, the state government is expected to get back money that can form a corpus to fund the scheme for the following year.
    • However, the state government would have to bear the financial liability in case of losses due to extreme weather events.

    Why is the government pushing for it for the entire state?

    • The reason why Maharashtra is pushing for this scheme is that in most years, the claims-to-premium ratio is low with the premium being paid to the company.
    • In the Beed model, the profit of the company is expected to reduce and the state government would access another source of funds.
    • The reimbursed amount can lead to lower provisioning by the state for the following year, or help in financing the paying the bridge amount in case of a year of crop loss.
    • For farmers, however, this model does not have any direct benefit.

    Challenges ahead

    • The chances of the model being implemented for the present Kharif season appear slim.
    • Questions remain on how the state government is going to raise the excess amount, and how the reimbursed amount would be administered.

  • CHIME Telescope

    Scientists with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Collaboration have assembled the largest collection of fast radio bursts (FRBs) in the telescope’s first FRB catalog.

    CHIME Telescope

    • CHIME is an interferometric radio telescope at the Dominion Radio Astrophysical Observatory in British Columbia, Canada.
    • It consists of four antennas consisting of 100 x 20-meter cylindrical parabolic reflectors with 1024 dual-polarization radio receivers suspended on support above them.
    • The telescope receives radio signals each day from half of the sky as the Earth rotates.
    • While most radio astronomy is done by swiveling a large dish to focus light from different parts of the sky, CHIME stares, motionless, at the sky, and focuses incoming signals using a correlator.
    • This is a powerful digital signal processor that can work through huge amounts of data, at a rate of about seven terrabytes per second, equivalent to a few percent of the world’s Internet traffic.

    What are FRBs?

    • FRBs are oddly bright flashes of light, registering in the radio band of the electromagnetic spectrum, which blaze for a few milliseconds before vanishing without a trace.
    • These brief and mysterious beacons have been spotted in various and distant parts of the universe, as well as in our own galaxy.
    • Their origins are unknown and their appearance is highly unpredictable.
    • But the advent of the CHIME project has nearly quadrupled the number of fast radio bursts discovered to date.
    • With more observations, astronomers hope soon to pin down the extreme origins of these curiously bright signals.

  • [pib] Fast Tracking Freight in India

    NITI Aayog, RMI and RMI India’s new report, Fast Tracking Freight in India: A Roadmap for Clean and Cost-Effective Goods Transport, presents key opportunities for India to reduce its logistics costs.

    Freight transport in India

    • Freight transportation is a critical backbone of India’s growing economy, and now more than ever, it’s important to make this transport system more cost-effective, efficient, and cleaner.
    • Due to the rising demand for goods and services, freight transport demand is expected to grow rapidly in the future.
    • While freight transport is essential to economic development, it is plagued by high logistics costs and contributes to rising CO2 emissions and air pollution in cities.

    Highlights of the Roadmap

    • According to the report, India has the potential to:
    1. Reduce its logistics cost by 4% of GDP
    2. Achieve 10 gigatonnes of cumulative CO2 emissions savings between 2020 and 2050
    3. Reduce nitrogen oxide (NOx) and particulate matter (PM) emissions by 35% and 28%, respectively, until 2050
    • The report outlines solutions for the freight sector related to policy, technology, market, business models, and infrastructure development.

    Various recommendations

    • The recommendations include increasing the rail network’s capacity, promoting intermodal transport, improving warehousing and trucking practices, policy measures and pilot projects for clean technology adoption, and stricter fuel economy standards.
    • When successfully deployed at scale, the proposed solutions can help India establish itself as a leader in logistics innovation and efficiency in the Asia–Pacific region and beyond.

    Transforming the system

    • As India’s freight activity grows five-fold by 2050 and about 400 million citizens move to cities, a whole system transformation can help uplift the freight sector.
    • This transformation will be defined by tapping into opportunities such as efficient rail-based transport, the optimization of logistics and supply chains, and a shift to electric and other clean-fuel vehicles.
    • These solutions can help India save ₹311 lakh crore cumulatively over the next three decades.

  • Centre announces hike in MSP

    The Central government has hiked the minimum support price (MSP) for the coming Kharif season. The decision was taken by the Cabinet Committee on Economic Affairs.

    Answer this PYQ from CSP 2018 in the comment box:

    Q.Consider the following:

    1. Areca nut
    2. Barley
    3. Coffee
    4. Finger millet
    5. Groundnut
    6. Sesamum
    7. Turmeric

    The Cabinet Committee on Economic Affairs has announced the Minimum Support Price for which of the above?

    (a) 1, 2, 3 and 7 only

    (b) 2, 4, 5 and 6 only

    (c) 1, 3, 4, 5 and 6 only

    (d) 1, 2, 3, 4, 5 and 7

    What is the Minimum Support Price (MSP) system?

    • MSP is a form of market intervention by the Govt. of India to insure agricultural producers against any sharp fall in farm prices.
    • MSP is price fixed by GoI to protect the producer – farmers – against excessive fall in price during bumper production years.

    Who announces it?

    • MSP is announced at the beginning of the sowing season for certain crops on recommendations by Commission for Agricultural Costs and Prices(CACP) and announced by Cabinet Committee on Economic Affairs (CCEA) chaired by the PM of India.

    Why MSP?

    • The major objectives are to support the farmers from distress sales and to procure food grains for public distribution.
    • They are a guaranteed price for their produce from the Government.
    • In case the market price for the commodity falls below the announced MSP due to bumper production and glut in the market, government agencies purchase the entire quantity offered by the farmers at the announced MSP.

    Historical perspective

    • Till the mid-1970s, Government announced two types of administered prices:
    1. Minimum Support Prices (MSP)
    2. Procurement Prices
    • The MSPs served as the floor prices and were fixed by the Govt. in the nature of a long-term guarantee for investment decisions of producers, with the assurance that prices of their commodities would not be allowed to fall below the level fixed by the Government, even in the case of a bumper crop.
    • Procurement prices were the prices of Kharif and rabi cereals at which the grain was to be domestically procured by public agencies (like the FCI) for release through PDS.
    • It was announced soon after harvest began.
    • Normally procurement price was lower than the open market price and higher than the MSP.

    Crops Covered

    1. Government announces minimum support prices (MSPs) for 22 mandated crops and fair and remunerative price (FRP) for sugarcane.
    2. The mandated crops are 14 crops of the kharif season, 6 rabi crops and two other commercial crops.
    3. The list of crops is as follows:
    • Cereals (7) – paddy, wheat, barley, jowar, bajra, maize and ragi
    • Pulses (5) – gram, arhar/tur, moong, urad and lentil
    • Oilseeds (8) – groundnut, rapeseed/mustard, toria, soyabean, sunflower seed, sesamum, safflower seed and nigerseed
    • Raw cotton
    • Raw jute
    • Copra
    • De-husked coconut
    • Sugarcane (Fair and remunerative price)
    • Virginia flu cured (VFC) tobacco

    Exception for Sugar

    • The pricing of sugarcane is governed by the statutory provisions of the Sugarcane (Control) Order, 1966 issued under the Essential Commodities Act (ECA), 1955.
    • Prior to 2009-10 sugar season, the Central Government was fixing the Statutory Minimum Price (SMP) of sugarcane and farmers were entitled to share profits of a sugar mill on 50:50 basis.
    • As this sharing of profits remained virtually unimplemented, the Sugarcane (Control) Order, 1966 was amended in October 2009 and the concept of SMP was replaced by the Fair and Remunerative Price (FRP) of sugarcane.

  • Legalizing Bitcoin in El Salvador and takeaways for India

    El Salvador, a small coastal country in Central America, on became the first in the world to make Bitcoin, a digital currency, legal.

    Lessons for India

    While there are many precedents El Salvador sets for a global debate on cryptocurrency, we explore what this means in the Indian context.

    (1) Not a precedent for monetary policy

    • The development in El Salvador changes little in terms of Indian monetary calculations around cryptocurrencies.
    • The dynamic underpinning the whole move is that El Salvador has no monetary policy of its own and hence, no local currency to protect.
    • The country was officially ‘dollarized’ in 2001 and runs on the monetary policy of the US Federal Reserve.
    • The move is in part motivated by loose and expansionary Federal Reserve policy.

    (2) Coexistence with USD

    • The dollar will continue to remain the dominant currency in the country and Bitcoin would exist side by side.
    • Indeed, some analysts have pointed out how bitcoinization might change nothing on the ground if “legal tender” is to be considered by its strict legal definition.
    • However, as a result of this development, El Salvador becomes a most interesting case study of how the dollar and bitcoin would coexist side by side, and how that would play out for Bitcoin adoption.

    (3) Not merely currency but technology

    • The overall use of Bitcoin appears less motivated by its use as a currency and much more by the image and investment boost this could give the country towards innovation.
    • El Salvador believes that this move will be good for luring “technology, talent, and new ideas” into the country.
    • The move into Bitcoin ties in with larger efforts to revive a stalling economy and bring back growth into the country post-Covid.

    (4) Potential shift in remittances

    • The impact Bitcoin has on these remittance inflows would be worth monitoring for India, which is home to the largest remittance market in the world.
    • Remittances make up close to 20% of El Salvador’s GDP with flows approximating $6 billion annually.
    • Many citizens lack a bank account and digital banking has low penetration.
    • In this scenario, there are multiple intermediaries in the remittance chain who take cuts of as high as 20%.

    (5) Impact on money laundering

    • The implication of this move for money laundering is unclear at the moment.
    • Currently, El Salvador is not considered deficient under the FATF money laundering requirements.
    • However, with large scale cryptocurrency inflows and outflows, it would be expected that El Salvador would comply with the 2019 FATF guidance on Virtual Currencies.

    Conclusion

    • The overall takeaway for India from the El Salvador case is not in the monetary sense at all.
    • This is the wealth that India has in spades and has barely protected with policy.
    • While deliberations continue in India on the monetary and financial regulations around cryptocurrency.
    • It is important that attention be paid to incentives for India’s developers working on key innovations in the space.

    Back2Basics: Bitcoin

    • Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries.
    • Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain.
    • The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto.
    • The currency began to use in 2009 when its implementation was released as open-source software.

  • India’s ethanol roadmap: The targets and challenges

    The government of India has advanced the target for 20 per cent ethanol blending in petrol (also called E20) to 2025 from 2030. E20 will be rolled out from April 2023.

    What is the move?

    • A government-appointed panel has recommended to the Centre to keep the price of ethanol-blended petrol lower than normal petrol in view of lower calorific value as also to incentivize people to go for the clean fuel.
    • This measure is aimed at reducing the country’s oil import bill and carbon dioxide pollution. This new initiative is also part of measures to improve energy security and self-sufficiency measures.

    Roadmap for Ethanol Blending

    • The central government has released an expert committee report on the Roadmap for Ethanol Blending in India by 2025.
    • The roadmap proposes a gradual rollout of ethanol-blended fuel to achieve E10 fuel supply by April 2022 and phased rollout of E20 from April 2023 to April 2025.
    • Currently, 8.5 per cent of ethanol is blended with petrol in India.
    • In order to introduce vehicles that are compatible the committee recommends roll out of E20 material-compliant and E10 engine-tuned vehicles from April 2023 and production of E20-tuned engine vehicles from April 2025.

    What is included in the roadmap?

    (1) Energy security

    • The Union government has emphasized that increased use of ethanol can help reduce the oil import bill.
    • India’s net import cost stands at $551 billion in 2020-21. It is estimated that the E20 program can save the country $4 billion (Rs 30,000 crore) per annum.
    • Last year, oil companies procured ethanol worth about Rs 21,000 crore.
    • Hence it is benefitting the sugarcane farmers.
    • Further, the government plans to encourage the use of water-sparing crops, such as maize, to produce ethanol, and the production of ethanol from the non-food feedstock.

    (2) Fuel efficiency

    • There is an estimated loss of six-seven per cent fuel efficiency for four-wheelers and three-four per cent for two-wheelers when using E20, the committee report noted.
    • These vehicles are originally designed for E0 and calibrated for E10.
    • The Society of Indian Automobile Manufacturers informed the expert committee that with modifications in engines (hardware and tuning), the loss in efficiency due to blended fuel can be reduced.

    (3) Recalibrating engines

    • The use of E20 will require new engine specifications and changes to the fuel lines, as well as some plastic and rubber parts due to the fuel’s corrosive nature.
    • The engines, moreover, will need to be recalibrated to achieve the required power-, efficiency- and emission-level balance due to the lower energy density of the fuel.
    • This can be taken care of by producing compatible vehicles.

    (4) Vehicles rollout

    • E20 material compliant and E10 compliant vehicles may be rolled out across the country from April 2023, the committee noted.
    • These vehicles can tolerate 10 to 20 per cent of ethanol-blended petrol and also deliver optimal performance with E10 fuel.
    • Vehicles with E20-tuned engines can be rolled out all across the country from April 2025.
    • These vehicles would run on E20 only and will provide high performance.

    (5) Flex-fuel

    • A flexible-fuel vehicle (FFV) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel and both fuels are stored in the same common tank.
    • The Union ministry of road transport and highways issued a gazette notification March 2021 mandating stickers on vehicles mentioning their E20, E85 or E100 compatibility.
    • This will pave the way for flex fuel vehicles.

    Why such a move?

    (1) Fuel efficiency

    • Considering just the end use also indicates that CO2 emissions from blended fuel are lower than that for petrol since ethanol contains less carbon than petrol and produces less CO2.
    • The blended fuel burns more efficiently with a more homogenous mixture, which leads to a decrease in CO2 emissions compared with pure petrol.
    • The carbon dioxide released by a vehicle when ethanol is burned is offset by the carbon dioxide captured when the feedstock crops are grown to produce ethanol.
    • Comparatively, no emissions are offset when these petroleum products are burned.

    (2) Emission reduction

    • Use of ethanol-blended petrol decreases emissions such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx), the expert committee noted.
    • Higher reductions in CO emissions were observed with E20 fuel — 50 per cent lower in two-wheelers and 30 per cent lower in four-wheelers.
    • HC emissions reduced by 20 per cent with ethanol blends compared to normal petrol.
    • Nitrous oxide emissions, however, did not show a significant trend as it depended on the vehicle / engine type and engine operating conditions.
    • The unregulated carbonyl emissions, such as acetaldehyde emission were, however, higher with E10 and E20 compared to normal petrol.
    • However, these emissions were relatively lower. Evaporative emission test results with E20 fuel were similar to E0.

    Global shreds of evidence

    • An increase in the ethanol content in fuels reduced the emissions of some regulated pollutants such as CO, HC and CO2.
    • However, no such change in emissions was observed for nitrogen oxides emissions.
    • The addition of ethanol, with a high blending octane number, however, allowed a reduction in aromatics in petrol.
    • Such blends also burn cleaner as they have higher octane levels than pure petrol but have higher evaporative emissions from fuel tanks and dispensing equipment.

    Challenges ahead

    • Petrol requires extra processing to reduce evaporative emissions before blending with ethanol.
    • It is crucial to study the emissions from flexible fuel vehicles not only for the regulated gases but also the unregulated ones.
    • But producing and burning ethanol results in CO2 emissions.
    • Hence, net CO2 emission benefit depends on how ethanol is made and whether or not indirect impacts on land use are included in the calculations.
    • In summary, as we progress towards higher blending of ethanol, careful monitoring and assessment of emissions changes will be needed to make sure that emission reduction potential can be enhanced.

    Back2Basics: EBP Programme

    • Ethanol Blended Petrol (EBP) programme was launched in January, 2003 for supply of 5% ethanol blended petrol.
    • The programme sought to promote the use of alternative and environment-friendly fuels and to reduce import dependency for energy requirements.
    • OMCs are advised to continue according to priority of ethanol from 1) sugarcane juice/sugar/sugar syrup, 2) B-heavy molasses 3) C-heavy molasses and 4) damaged food grains/other sources.
    • At present, this programme has been extended to the whole of India except UTs of Andaman Nicobar and Lakshadweep islands with effect from 01st April 2019 wherein OMCs sell petrol blended with ethanol up to 10%.

  • Places in news: Sardar Sarovar Dam

    The Sardar Sarovar Dam is providing irrigation water in summer for the first time in history.

    Sardar Sarovar Dam

    • The Sardar Sarovar Narmada Dam is a terminal dam built on the Narmada river at Kevadia in Gujarat’s Narmada district.
    • Four Indian states, Gujarat, Madhya Pradesh, Maharashtra and Rajasthan, receive water and electricity supply from the dam.
    • The foundation stone of the project was laid out by Prime Minister Jawaharlal Nehru on 5 April 1961.
    • The project took form in 1979 as part of a development scheme funded by the World Bank through their International Bank for Reconstruction and Development, to increase irrigation and produce hydroelectricity
    • Called the ‘lifeline of Gujarat’, it usually has no water for irrigation during summers.

    Q.Which one of the following pairs is not correctly matched?

     

    Dam/Lake River

    (a) Govind Sagar: Satluj

    (b) Kolleru Lake: Krishna

    (c) Ukai Reservoir: Tapi

    (d) Wular Lake: Jhelum

    A successful model of river water sharing

    • River Narmada is a classic case of Integrated River Basin Planning, Development, and Management, with water storage available in all major, medium, and minor dams on the main river and its tributaries.
    • Its water is shared amongst four party states – Gujarat, Rajasthan, Madhya Pradesh and Maharashtra — in the ratio stipulated by the 1979 award of the Narmada Water Dispute Tribunal.

    How has it saved water for summers?

    • During the monsoon from July to October, the reservoir operation is well synchronized with the rain forecast in the catchment area.
    • The strategic operation of River Bed Power House (RPBH) ensures that minimum water flows downstream into the sea and maximum water is used during the dam overflow period, which is not calculated in the annual water share.
    • These measures help in maximizing the annual allocation of water share.
    • Similarly, in non-monsoon months, the measures for efficient use of the allocated share typically include minimizing the conventional and operational losses.
    • It includes: avoiding water wastage, restricting water-intensive perennial crops, adopting of Underground Pipelines (UGPL); proper maintenance and operation of canals on a rotational basis.
