Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.

California ARB moves forward with climate and air quality actions

Green Car Congress

Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. CARB began publicly evaluating controls for SLCPs with the first AB 32 Scoping Plan in 2008 and has held at least 10 workshops and public hearings to gather input.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

2009), reproduced from Ramanathan and Feng (2008) Click to enlarge. HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. The Montreal Protocol has already delayed climate change by seven to 12 years, and put the ozone layer on the path to recovery later this century. Ramanathan.

UNEP Report Calls for More Sophisticated Approach to Developing Biofuels; Limitations of Current LCA Studies

Green Car Congress

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. From 2007 to 2008, the share of ethanol in global gasoline type fuel use was estimated to increase from 3.78% to 5.46%, and the share of biodiesel in global diesel type fuel use from 0.93% to 1.5%.
