Study estimates California’s GHG reductions since 2003 could be wiped out by 2020 wildfires

Green Car Congress

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

Next 10 report finds California must increase GHG reductions to 4.9%/year through 2030 to meet target

Green Car Congress

The largest one-year emissions drop California has ever achieved was at the height of the Great Recession in 2009, when climate pollution fell 6.1%. This level is still below the state’s first climate milestone (2020’s AB 32 goal, met four years early in 2016) of reducing to 431 MMTCO 2 e below 1990 levels. lower and 8.3%

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

Hydrogen Fuel Cell Buses entering service in London; planned fleet of 8

Green Car Congress

The RV1 route passes through some of London’s most polluted areas, so its conversion to hydrogen power will help to improve London’s air quality. This is set to expand to 300 and, from 2012, will be joined by the Mayor’s New Bus for London, which will be 40% less polluting than a traditional diesel bus.
