Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible. According to the researchers, emissions from these CFCs currently do not significantly threaten ozone recovery.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.

US, China, and G-20 agree to work to global phase down of HFCs

Green Car Congress

The US reached separate agreements with the G-20 and with China to address the rapid growth in the use and release of climate-damaging hydrofluorocarbons (HFCs). Left unabated, HFC emissions could grow to nearly 20% of carbon dioxide emissions by 2050, a serious climate mitigation concern.
