Possible to reduce Delhi PM 2.5 winter level by 46%, tackle both peak and non-peak pollution sources: TERI


New Delhi: November 13, 2019: The Energy and Resources Institute (TERI) has prepared a strategic plan for solving Delhi’s air pollution crisis which worsens during winters every year. Speaking at the Sustainable Dialogue on Air Pollution, co-organised with Natural Resources Defense Council (NRDC), Dr Ajay Mathur, Director General, TERI said, “Delhi’s air pollution is a solvable problem. There are solutions both in terms of technologies and for meeting the necessary costs. TERI is putting forward definitive measures for addressing peak and non-peak pollution sources, both of which are absolutely essential to improve Delhi’s air quality. We can immediately start working towards implementation, if all stakeholders come together.”

Dr Sumit Sharma, Director, Earth Science and Climate Change Division, TERI added, ‘’Some of the  peak air pollution episodes during winters can be avoided by controlling agriculture crop burning and fire crackers. But this can only bring down the pollution levels to ‘very poor’ category. However, if we address both peak and non-peak sources such as transport, industries, residential and road dust, it is possible to reduce Delhi’s PM 2.5  level by 46% during winters, which can restore air quality to ‘moderate’ category.’’

Mr C K Mishra, Secretary, Ministry of Environment, Forests and Climate Change (MoEFCC), Government of India in his keynote address at the dialogue said, “In the last two years, efforts by the government in tackling air pollution have been phenomenal but the results achieved are marginal. We need at least 50% reduction in current air pollution levels. This needs sustained efforts. Emergency and knee-jerk reactions will not help.”

He further added that air pollution cannot be the government’s business alone. “Everyone has a role to play. Even if there is an adverse cost, it should be paid,” he said.

Talking about global experience in tacking air pollution, Mitchell Bernard, Interim President and Chief Counsel, NRDC said, ‘’It has helped when air pollution has been linked to the health and economy of a country. It is not a narrow environmental issue. There is a huge public health cost. And there is a strong economic argument to be made for combating air pollution on account of lost productivity, medical costs, and opportunity costs.’’

Speaking about the looming health crisis, Dr Arvind Kumar, Chairman, Centre for Chest Surgery, Sir Ganga Ram Hospital said, “In 1988, patients of lung cancer were mostly known smokers. In 2018, 50% cases of lung cancer are non-smokers.’’ He warned that Delhi is likely to see an explosion of lung cancer cases in the coming years.
