NCAP, non-NCAP cities show similar trends in PM2.5 levels, CSE analysis | India News
Bathanda: There is hardly any difference in total particulate matter 2.5 (PM2.5) trends between the sub-cities. National Clean Air Program (NCAP) and those outside its scope, explains a new analysis from the Center for Science and Environment (CSE), released on Tuesday to mark the UN International Day of Clean Air for Blue Skies. It said that both groups of cities reflected similar mixed trends in air quality across different climatic zones, indicating that they had to meet the national ambient air quality standards for particulate pollution levels. I need a substantial reduction. There are 16 NCAP cities and 15 non-NCAP cities that have registered significant increases in their annual PM2.5 levels – with almost identical numbers. The same holds true for cities (20 NCAP and 21 non-NCAP) that have recorded significant improvement in their annual PM2.5 levels. The severe and extended lockdown in 2020 due to the pandemic had significant impacts on air quality in all monitored cities. But there is negligible difference between the impact on NCAP and non-NCAP cities. Both groups of cities recorded a decrease of about 12 percent in their overall 2020 PM2.5 levels compared to last year. Pollution returned in 2021 with nearly equal intensity in both groups. NCAP cities recorded an overall increase of 8 percent in their annual PM2.5 levels in 2021 from the lowest levels in 2020. Similarly, non-NCAP cities recorded a 7 percent increase. . This makes the case for both NCAP and non-NCAP cities requiring substantial reductions to meet national ambient air standards. NCAP has set a national level target of 20-30% reduction in PM2.5 and PM10 concentrations from the base year of 2017 to 2024. But the Central Pollution Control Board (CPCB)’s latest NCAP assessment of cities’ performance has considered only PM10 data, which is mostly coarse dust particles, for disbursing performance-linked funds. Because monitoring of PM2.5 – the smallest particles that are highly harmful – is limited, uniform assessment of cities based on PM2.5 reduction has not been considered for performance assessment. CSE conducted a national analysis of PM2.5 levels in cities for which data is available to understand trends in both NCAP and non-NCAP cities, and reductions in both groups of cities to meet national clean air standards. level is required. . It also addressed air quality monitoring in terms of manual and real-time monitoring, the extent of PM10 and PM2.5 monitoring in cities, and data quality challenges for constructing and validating long-term air quality trends. What is exposed? NCAP covers 132 cities — 82 of them have been funded through the program, while 50 cities have received funds from the 15th Finance Commission. 6,425 crore has been released till 2021-22 and Rs 2,299 crore has been allocated for 2022-23. Cities need to quantify improvements starting in 2020-21 – requiring a 15 percent or more reduction in annual average PM10 concentrations and an increase of more than 200 days of good air. Anything less will be considered low and funding will be reduced. . “While it is encouraging that Clean Air Action funding is linked to performance and the ability of cities to demonstrate improvements in air quality, relying solely on manual monitoring of PM10 obviously creates a cost bias because It focuses more on dust control and reduction. Focusing on comprehensive action on industry, vehicles, waste and solid fuel burning,” he says. Anumita Rai ChowdhuryExecutive Director, Research and Advocacy at CSE. NCAP’s Punjab, Rajasthan and Maharashtra cities dominate the list of cities that have recorded a significant increase in PM2.5 levels between 2019 and 2021. There are 46 cities that are not covered by NCAP, but have adequate real-time data for both 2019 and 2021. In this group, 15 cities recorded a significant deterioration in annual PM2.5 levels between 2019 and 2021. Ankleshwar in Gujarat is the worst performer in the pool with percentage increase in annual PM2.5 value at 34, followed by Satna (Madhya Pradesh), Vatva (Gujarat), Bahadurgarh (Haryana), and Bathinda (Punjab); All of them have increased by more than 20 percent. Cities in Haryana, Madhya Pradesh and Gujarat topped the list of non-NCAP cities that recorded a significant increase in air pollution levels between 2019 and 2020. However, Palwal in South Haryana has improved its annual PM 2.5 levels by 60%. Best performer in non-NCAP cities.
