CSE slams the statement of Jaguar and Land Rover Chief – about their cars being air-purifying machines – as irresponsible

CSE says car companies cannot be allowed to hide behind such misleading claims when the technology in India is lagging and there are raging concerns around toxic diesel emissions even in advanced markets today.  No car company can get away by making such remarks in any other country

Kolkata residents breathe in air which has 3-5 times higher pollution levels than the ambient level that is already several times higher than the permissible limit. Action must gather momentum, says CSE’s Kolkata study

  • Kolkata is in the grip of rising air pollution and multi-pollutant crisis. Official ambient air quality monitoring has shown 61 per cent increase in particulate matter in just four years (2010 to 2013). The levels exceed standards by 2.7 times. NO2 levels exceed by close to two times

Status of air pollution during winter of 2015-16 and the impact of odd-even car rationing scheme on air quality

January 21, 2016

1. Overall pollution level this winter is higher than last winter. This demands emergency action

This winter has witnessed extremely high level of pollution. Typical winter conditions -- cold temperature, lower mixing height of air, calm and no-wind conditions trap air and pollution. As a result, pollution builds up very quickly and peaks. This is why winter months require tougher emergency action to reduce pollution. Weather is an important constraint in pollution management.

“A great step forward”, says CSE, on the Union government’s move to leapfrog to Euro VI emissions standards in 2020

  • Diesel car emissions will be reduced to the level of petrol emissions; diesel particulate levels from diesel cars, buses and trucks will come down drastically

Make bus the game changer, says CSE

It is shocking how bus transport that carries double the number of passengers in Delhi Metro is degenerating when Delhi has to reduce personal vehicle usage to curb pollution and congestion

CSE extends support to the odd-even number formula but expresses disappointment at too many exemptions granted to several vehicle segments

This can seriously compromise the effectiveness of this emergency action needed to control the peak pollution levels during winter.  Design the programme to make a difference to the air quality of Delhi.
