Study finds that California clean diesel programs have slashed black carbon, a powerful short-term contributor to global warming

Green Car Congress

California’s air quality programs have forced a reduction in black carbon despite a significant increase in diesel fuel consumption. If California’s efforts in reducing black carbon can be replicated globally, we can slow down global warming in the coming decades by about 15 percent, in addition to protecting people’s lives.

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

Green Car Congress

Global and regional-mean temperature responses to identical aerosol emissions in different regions. Diagonal lines (b) indicate the ratio of regional- to global-mean cooling. For example, their models show that aerosol emissions from Western Europe have 14 times the global cooling effect that aerosol emissions from India do.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). million lives lost each year due to black carbon soot.

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.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario. Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

In a recently published whitepaper on hydrogen opposed-piston engines (H 2 -OPE), opposed-piston engine maker Achates Power explained that since there are no carbon molecules in hydrogen fuel, neither unburned hydrocarbons nor particulate matter is a concern for emission control from a hydrogen combustion engine. Shell plc, London, England.

CARB releases summary of results of first CO2 cap-and trade auction; CPUC proposes how to use the revenues

Green Car Congress

One allowance permits the release of one metric ton of carbon dioxide. The auction was a success and an important milestone for California as a leader in the global clean tech market. By putting a price on carbon, we can break our unhealthy dependence on fossil fuels and move at full speed toward a clean energy future.
