  • [7th February 2025] The Hindu Op-ed: The saga of regulating India’s thermal power emissions

    PYQ Relevance:

    Q) Describe the benefits of deriving electric energy from sunlight in contrast to the conventional energy generation. What are the initiatives offered by our government for this purpose? (UPSC CSE 2020)

     

    Mentor’s Comment: UPSC mains have always focused on Environmental Impact Assessment studies (2015), and conventional energy generation (2020).

    On December 30, 2024, the MoEFCC extended the deadline for thermal plants to meet SO₂ emission norms by three years without explanation. Originally set for December 31, 2024, this delay affects 20 GW of plants near densely populated areas. These norms were set in 2015 to tighten particulate matter limits and introduced SO₂ norms for the first time, aligning them with standards in countries like Australia, China, and the U.S., despite the short timeline for compliance.

    Today’s editorial talks about the revised emission norms for Indian thermal plants and impact of these norms. This content will help in GS Paper 3.

    _

    Let’s learn!

    Why in the News?

    On December 30, 2024, India’s Ministry of Environment, Forest and Climate Change (MoEFCC) changed the Environment Protection Rules, extending the deadline for thermal power plants to meet sulphur dioxide (SO₂) emission standards by three years without providing any explanation.

    What are the revised emission norms for Indian thermal plants?

    • New Deadlines: On December 30, 2024, India’s Ministry of Environment, Forest and Climate Change (MoEFCC) extended the deadlines for thermal power plants to comply with sulphur dioxide (SO₂) emission norms by three years. The revised deadlines are:
      • Category A (By Dec 31, 2027) – Thermal plants within 10 km of NCR or cities with over 1 million population (e.g., Dadri NTPC, Koradi) must comply first due to high pollution and population density.
      • Category B (By Dec 31, 2028) – Plants in critically polluted areas or non-attainment cities (e.g., Singrauli, Korba, Chandrapur) get extended timelines due to severe environmental concerns.
      • Category C (By Dec 31, 2029) – All other plants (e.g., Talcher, Mundra, Simhadri) must comply last as they are in lower-risk areas with relatively better air quality.
    • Historical Context: The original norms were established in December 2015, with an initial compliance deadline set for December 2017. This was later extended multiple times due to various challenges.

    Note: The categories for compliance with SO₂ emission norms for Indian thermal power plants are based on location and environmental impact.

    What are the challenges around implementing the flue gas desulphurisation (FGD) technology?

    • Technical and Financial Hurdles: The implementation of FGD technology has faced delays primarily due to high costs, inadequate supply chains, and operational complexities. Many plants tendered contracts for FGDs but did not progress at a pace necessary to meet earlier deadlines.
    • Debate on Necessity: Recent studies commissioned by NITI Aayog and conducted by CSIR-NEERI have questioned the urgency and necessity of FGD installations for improving air quality, suggesting that focus should instead be on particulate emissions. This has led to confusion and varied interpretations of compliance requirements among stakeholders.

    How successful has India been in implementing emission norms for thermal power plants?

    • Limited Progress: As of late 2024, only about 22 GW of thermal capacity had installed FGDs, which is less than 8% of the total coal-fired power generation capacity in India. The overall progress has been slower than anticipated since the introduction of the norms.
    • Compliance Monitoring Issues: There is a lack of transparency regarding adherence to existing norms, as pollution control boards have not consistently verified compliance. This raises concerns about the effectiveness of regulatory oversight.

    What are the economic and environmental consequences of noncompliance and what measures are in place to address this?

    • Health Impacts: The extension of compliance deadlines poses risks to public health, especially in densely populated areas like Delhi-NCR, where air pollution is already a critical issue. SO₂ is known to contribute to respiratory and cardiovascular diseases.
    • Financial Burden on Consumers: Electricity regulators have allowed thermal plants to pass on the costs of installing FGDs to consumers, regardless of whether emission norms are met. This means consumers may end up paying for pollution control equipment that remains unused due to extended compliance timelines.
    • Environmental Compensation: For non-compliance beyond specified timelines, MoEFCC has introduced an environmental compensation scheme that penalizes plants based on their duration of non-compliance. This includes fees that escalate over time but may not be sufficient to incentivize timely compliance.

    Way forward: 

    • Strict Enforcement & Incentives – Strengthen regulatory oversight with real-time emissions monitoring, enforce penalties for non-compliance, and provide financial incentives or subsidies to accelerate FGD adoption.
    • Balanced Policy Approach – Address technical and financial barriers by improving supply chains, supporting domestic FGD manufacturing, and ensuring a phased yet firm transition while prioritising high-risk areas.

  • Asteroid 2024 YR4

    Why in the News?

    NASA has identified a newly discovered near-Earth asteroid, 2024 YR4, which has a slightly more than 1% chance of impacting Earth in 2032.

    Asteroid 2024 YR4

    Asteroid 2024 YR4 and its Geographical Features:

    • The asteroid was discovered in December 2024 by an observatory in Chile.
    • It measures between 40 to 100 meters across, making it roughly the size of a football field.
      • The exact size is uncertain because astronomers estimate an asteroid’s size based on its brightness.
    • On December 25, 2024, the asteroid passed within 800,000 kilometers of Earth, which is approximately twice the distance of the Moon.
    • It will fade from sight in April 2025 and will not be visible again until 2028, when it approaches Earth once more.
    • The asteroid is currently rated 3 on the Torino Scale, which measures the risk of impact on a scale from 0 to 10.

    Potential Destruction from 2024 YR4 Impact:

    • If 2024 YR4 collides with Earth, it is expected to release between 8 to 10 megatons of energy, equivalent to multiple nuclear explosions.
    • It injured 1,500 people and damaged thousands of buildings across several cities.
    • In comparison, the Apophis asteroid, discovered in 2004, was initially rated 4 but was later downgraded after further observations ruled out an impact threat.

    How often do Asteroids crash Into Earth?

    • Thousands of small asteroids burn up in Earth’s atmosphere daily due to friction.
    • The Chelyabinsk meteor (2013) exploded over Russia with 30 times the power of the Hiroshima bomb.
    • Asteroids around 40 meters can cause regional destruction if they hit Earth.
    • Large asteroids (1 km+ in size) can trigger global disasters, occurring about once every 260 million years.
    • The Chicxulub asteroid (66 million years ago) led to the extinction of dinosaurs.

    How Space Agencies prevent Asteroid Collisions?

    • NASA and global space agencies work on planetary defense to prevent impacts.
    • In 2022, NASA’s DART mission successfully changed asteroid Dimorphos’s trajectory using kinetic impact.
    • Scientists explore 3 key methods for asteroid deflection:
      • Kinetic Impact:  Using spacecraft to hit an asteroid and alter its path.
      • Gravity Tractors:  Using a spacecraft’s gravity to pull an asteroid off course.
      • Nuclear Explosions: As a last resort, detonating a nuclear device near an asteroid to deflect or destroy it.

  • What is the SC directive on sacred groves?

    Why in the News?

    On December 18, 2024, the Supreme Court ordered Rajasthan’s Forest Department to map all sacred groves using satellite and ground surveys based on their cultural and ecological importance, regardless of their size.

    Note: In Rajasthan, sacred groves, locally known as ‘orans’, are estimated to number around 25,000, covering approximately 6 lakh hectares across the state.

    What are the implications of the December 18 order? 

    • Conflict with the Forest Rights Act (FRA), 2006 – The order contradicts the FRA, which was enacted to recognize and vest forest rights with gram sabhas. Instead, the decision shifts control from communities to the Forest Department.
    • Loss of Community Autonomy – Sacred groves, which have been traditionally protected by local communities, will now be governed by state authorities, potentially disrupting cultural conservation practices.
    • Potential Erosion of Traditional Governance Systems – The transfer of management could weaken customary laws and traditional conservation practices that have preserved these groves for generations.
    • Legal Precedence for Future Cases – By prioritizing the Wildlife Protection Act (WLPA), 1972, over the FRA, this order may set a precedent for other community-managed lands to be taken over by the Forest Department.
    • Impact on Livelihoods and Religious Practices – Communities that depend on sacred groves for religious, medicinal, and cultural purposes may face restrictions under the new classification as ‘community reserves’.

    What did T.N. Godavarman v. Union of India establish about the definition of ‘forest land’? 

    • Broad Definition: The Supreme Court established that ‘forest land’ includes not only areas understood as forests in the dictionary sense but also any area recorded as forest in government records, regardless of ownership.
    • Expert Committees: The ruling directed state governments to form expert committees to identify areas that fit this definition of ‘forest land’.

    How are sacred groves traditionally conserved by communities?

    • Watershed & Ecological Functions: Many sacred groves protect natural water sources, prevent soil erosion, and regulate local climate. Example: Orans (Rajasthan) – These groves support perennial water streams and serve as critical grazing lands for livestock.
    • Strict Protection through Customary Laws & Taboos: Communities impose strict prohibitions on tree felling, hunting, or resource extraction in sacred groves. Example: Sarpa Kavu (Kerala) – These groves are dedicated to serpent deities, and cutting trees is considered a bad omen.
    • Religious & Cultural Practices for Conservation: Rituals, festivals, and community prayers reinforce the spiritual importance of these groves. Example: Devara Kadu (Karnataka) – Annual worship ceremonies maintain local participation in conservation efforts.
    • Community Governance & Management: Local elders, priests, or village councils oversee the maintenance and enforcement of protection norms. Example: Jahera (Odisha, Chhattisgarh) – Tribal communities like the Gonds and Santhals manage these groves as sacred spaces.
    • Role in Biodiversity Preservation: The groves act as biodiversity hotspots, protecting endemic flora, fauna, and medicinal plants. Example: Law Kyntang (Meghalaya) – Khasi communities conserve these forests, which shelter rare orchids and medicinal herbs.

    Way forward:

    • Harmonizing Legal Frameworks – Amend policies to ensure the Forest Rights Act (FRA), 2006, and Wildlife Protection Act (WLPA), 1972, work in tandem, recognizing gram sabhas’ authority in managing sacred groves while ensuring ecological conservation.
    • Community-Centric Conservation – Strengthen traditional governance systems by legally empowering local communities to manage sacred groves, integrating scientific conservation methods with cultural practices.

  • The science is clear, crowd disasters are preventable

    Why in the News?

    This week in India, a tragic crowd crush at the Maha Kumbh claimed the lives of 30 people.

    What scientific evidence supports the prevention of crowd disasters?

    • Crowd Density Studies: Research indicates that crowd crushes become dangerous at densities of five persons per square meter, with serious risks emerging at seven persons per square meter or more. This evidence underscores the need for effective crowd management to prevent dangerous overcrowding.
    • Predictability of Crowd Behavior: Scientific studies have shown that crowd dynamics can be predicted and managed. By understanding how crowds behave in different environments, planners can implement strategies to avoid conditions that lead to crushes.
    • Historical Data on Past Incidents: Analysis of previous crowd disasters reveals common factors leading to fatalities, such as inadequate space and poor crowd control measures. Lessons learned from these incidents can inform better practices for future events.

    How can effective crowd management practices be implemented at large events?

    • Strategic Planning: Event organizers should create a comprehensive plan that includes crowd flow evaluation, risk assessment, and clearly marked exits and entrances. This planning should involve local officials to ensure safety measures are adequate.
    • Staggered Entry and Exit Times: To reduce peak crowd density, organizers can stagger arrival and departure times for attendees, allowing for a more manageable flow of people into and out of the venue.
    • Use of Barriers: Implementing physical barriers can help segment crowds into smaller groups, reducing the likelihood of dangerous surges. Barriers should be designed to allow for emergency exits if needed.
    • Crowd Monitoring Systems: Utilizing technology for real-time monitoring of crowd density and behaviour can help event staff respond quickly to potential dangers. Mass notification systems can alert staff about growing concerns, enabling timely interventions.
    • Staff Training and Communication: Ensuring that all staff and security personnel are trained in crowd management techniques is essential. Clear communication protocols should be established to relay information quickly during an event.

    What role do policies and regulations play in enhancing crowd safety?

    • Mandatory Safety Regulations: Governments should introduce regulations requiring event organizers to adhere to safety standards that limit crowd density and ensure adequate emergency planning. Such policies can hold organizers accountable for crowd safety.
    • Economic Incentives for Compliance: While event organizers often prioritize profit over safety, regulations can create incentives for them to implement safer practices, such as limiting ticket sales based on venue capacity.
    • Post-Incident Reviews and Accountability: Establishing a framework for reviewing crowd disasters can lead to improved regulations and practices in the future. Accountability measures can encourage compliance with safety standards among event planners and local authorities.
    • Public Awareness Campaigns: Governments can promote awareness about crowd safety among the public, educating attendees on how to behave in crowded situations and the importance of following safety protocols during events.

    What are the steps taken by the government?

    • National Disaster Management Authority (NDMA) Guidelines: The NDMA has formulated guidelines to ensure safe crowd management during mass gatherings. These guidelines include regulating traffic, using barricades, and ensuring adequate police presence to manage crowds effectively.
    • Capacity Evaluation: Before hosting large events, there is a requirement for proper evaluation of the venue’s capacity. This ensures that the infrastructure can handle the expected crowd size without leading to dangerous overcrowding.
    • Use of Technology: The government encourages the deployment of advanced technologies such as CCTV surveillance, drones for aerial monitoring, and public address systems to enhance crowd management and safety.
    • Traffic Management: Effective traffic management strategies are implemented, including displaying route maps, managing unauthorized parking, and controlling pedestrian flow around event venues to prevent bottlenecks.

    Way forward: 

    • Strengthen Regulatory Framework – Governments should enforce stricter crowd safety regulations, mandating capacity limits, emergency preparedness, and real-time crowd monitoring for all large events.
    • Enhance Technological Integration – Deploy AI-based crowd analytics, drone surveillance, and real-time alert systems to monitor crowd density and movement. Training event staff in using these technologies will improve response times and prevent disasters.
