Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. In future, with greater use of lower carbon electricity in the European mix the typical GHG emissions saving of BEVs relative to ICEVs will increase.

Study finds some improved cookstoves may emit more black carbon pollution than traditional mud cookstoves

Green Car Congress

The first real-world, head-to-head comparison of improved cookstoves (ICs) and traditional mud stoves has found that some ICs may at times emit more of the black carbon particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires.

PNNL modeling study finds climate benefit for cutting soot, methane smaller than previous estimates

Green Car Congress

Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.

EPA report to Congress finds a strong scientific and technical foundation for mitigating black carbon emissions

Green Car Congress

The US Environmental Protection Agency (EPA) has submitted its final Report to Congress on Black Carbon , in response to an October 2009 request from Congress to advance efforts to understand the role of black carbon (BC) in climate change. —Report to Congress on Black Carbon.

Field study finds soot particles absorb significantly less sunlight than predicted by models; climate models may be overestimating warming by BC

Green Car Congress

Although viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. —Cappa et al.
