NEW DELHI: Environmental and transportation experts on Wednesday discussed ways and means to mitigate black carbon (BC) emissions that can help reduce health impacts from air pollution as well as t

President Barack Obama delivered the 2015 State of the Union speech on Tuesday in front of a joint session of Congress, laying out his policy vision for the next year.

China’s largely unregulated ports and shipping system generate significant air pollution that imposes a huge health and environmental burden and contributes to the country’s over 1 million pollution-related deaths each year, according to a new report released by the Natural Resources Defense Council (NRDC).

Aug 12 (Reuters) - China's capital Beijing cut total coal consumption by 7 percent in the first half of 2014 as part of its efforts to tackle smog, the official Xinhua news agency reported, citing

Mexico is planning to revise its existing emissions standards for diesel heavy-duty vehicles (HDVs). The existing regulation, Norma Oficial Mexicana 044 (NOM 044), requires new vehicles to meet either U.S. Environmental Protection Agency (EPA) 2004 or Euro IV standards.

These rules may be called the Central Motor Vehicles (11th Amendment) Rules, 2014. On July 4, 2014, India finalized the fourth stage of emission standards for motorized two- wheeled vehicles.

China should establish emissions inventories for all major port cities as soon as possible to detail pollutants from ships and ports, experts have suggested.

The U.S. Supreme Court sidestepped a dispute over whether California’s low-carbon fuel standard discriminates against out-of-state ethanol producers.

A 2013 scientific assessment of black carbon emissions and impacts found that black carbon is second to carbon dioxide in terms of its climate forcing. High concentrations of black carbon in the atmosphere can change precipitation patterns and reduce the amount of radiation that reaches the Earth's surface, which affects local agriculture. Acute and chronic exposures to particulate matter are associated with a range of diseases, including chronic bronchitis and asthma, as well as premature deaths from cardiopulmonary disease, lung cancer, and acute lower respiratory infections. The transportation sector accounted for approximately 19 percent of global black carbon emissions in the year 2000. This report aims to inform efforts to control black carbon emissions from diesel-based transportation in developing countries. It presents a summary of emissions control approaches from developed countries, while recognizing that developing countries face a number of on-the-ground implementation challenges. A cost-benefit framework for economic analysis of diesel black carbon emissions control transport projects is also presented that factors in both climate and health benefits.
