Mains Paper 3: Environment | Conservation, environmental pollution and degradation, environmental impact assessment
From UPSC perspective, the following things are important:
Prelims level: Name of air pollutants notified
Mains level: Financing clean energy and cost of non complinace of such measures
The effort to clean up India’s thermal power plants running on coal has never really taken off, despite the Ministry of Environment notifying emission limits for major pollutants such as suspended particulate matter, sulphur oxide, nitrogen oxide and mercury in December 2015.
Notification Regarding Pollution Control
- Ministry of Environment notified emission limits for major pollutants such as suspended particulate matter, sulphur oxide, nitrogen oxide and mercury in December 2015.
- Considering that the cumulative impact of these pollutants on the health and well-being of people is severe, the Centre should have followed up the notification with a viable financial plan to help power plants acquire pollution control technologies.
- The economics favours such an approach for the larger plants.
- For the smaller, older units, scaling down generation during the winter months when pollutants accumulate may prove beneficial.
- Originally, the compliance deadline was set for 2017, but that was missed and the plan now is to achieve the norms by 2022.
Cost of Non-Compliance
- Greenpeace India, suggest the estimated cost of non-compliance by the original deadline has been about 76,000 premature deaths.
- The Center for Study of Science, Technology and Policy, put the positive outcomes from achieving pollution control at coal-fired plants by 2025 at potentially 3.2 lakh lives saved from premature death, and 5.2 crore respiratory hospital admissions avoided in the next decade.
- The latest proposal from the Power Ministry to provide the equivalent of over $12 billion (about ₹88,000 crore), mainly to remove sulphur from coal plant emissions, becomes important.
Planning Financing Pollution Control Measures
- A viable financial mechanism must be evolved to remove pollutants in existing and upcoming power plants.
- Stop further long-term investments in a dirty fuel such as coal that contributes to carbon emissions.
- The burden of incorporating pollution control should fall on the beneficiary-user, which in simple terms would translate into a tariff hike.
- Achieving speedy implementation of the new processes covering both public and private power producers may require some form of immediate governmental support, such as grants.
- Because, power producers that have borrowed from several institutions, including state-funded ones, are reported to be under severe financial stress.
- India’s coal use represents just over 54% of the present energy mix, and the fuel will continue to retain a high share of the overall generation.
- The challenge, therefore, is to identify the right instruments to fund the entire exercise, in the interests of pollution control and extending electricity access to the unreached.
- A positive spin-off from sulphur-removal will be, since it can yield commercially significant quantities of synthetic gypsum.
- The benefits of clean air to public health would make the investment well worth the effort.
