UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario.

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

Green Car Congress

The climate change benefit is estimated for a given year (2050) and human health and crop benefits are. 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

World Bank to focus on reducing short-lived climate pollutants; transport projects

Green Car Congress

A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs. Over the six-year period of the review (FY2007-2012), 7.7

Here’s How We Could Brighten Clouds to Cool the Earth

Cars That Think

As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.
