The Delhi Metro (DM) is a mass rapid transit system serving the National Capital Region of India. It is also the world’s first rail project to earn carbon credits under the Clean Development Mechanism of the United Nations for reductions in CO2 emissions. Did the DM also lead to localized reduction in three transportation source pollutants?

With densely-populated areas in the city, especially Punjabi Bagh and R.K.

Heavy air pollution in the city is causing not just respiratory problems, but also resulting in an increased risk of people developing heart diseases.

Bharat Stage IV (BS-IV) emission standards, being implemented in phases for various categories of vehicles to check automobile pollution, will become applicable for four-wheelers in Kerala from Apr

Chandrapur: Greta power company has rubbished the allegation of MLC Shobhatai Fadnavis about use of powdered rubber from tyres as raw material in their plant located at Mul MIDC.

BHUBANESWAR: At least 35 industries are yet to provide real time (online) data on pollution to the Odisha State Pollution Control Board (OSPCB), despite installing the required equipment.

NAVI MUMBAI: While the environment quality index (EQI) has improved in Navi Mumbai, it has become increasingly difficult to inhale clean air in the city.

China's emissions of two key pollutants fell slightly in the first half of 2015, according to the environment ministry, as authorities stepped up punitive measures to combat environmental degradati

Existing carbon offset protocols for improved cookstoves do not require emissions testing. They are based only on estimated reductions in the use of non-renewable biomass generated by a given stove, and use simplistic calculations to convert those fuel savings to imputed emissions of carbon dioxide (CO2). Yet recent research has shown that different cookstoves vary tremendously in their combustion quality, and thus in their emissions profiles of both CO2 and other products of incomplete combustion.

China has recently made available hourly air pollution data from over 1500 sites, including airborne particulate matter (PM), SO2, NO2, and O3. We apply Kriging interpolation to four months of data to derive pollution maps for eastern China. Consistent with prior findings, the greatest pollution occurs in the east, but significant levels are widespread across northern and central China and are not limited to major cities or geologic basins. Sources of pollution are widespread, but are particularly intense in a northeast corridor that extends from near Shanghai to north of Beijing.
