Trucks are a major contributor to air pollution and fuel guzzling with serious public health and climate change consequences. Rapid growth in the economy and trade is continuously expanding roadbased freight traffic, bringing more and more trucks on roads.

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.   Read more (pdf)
