Airborne measurements show ozone-forming VOCs emissions from ethanol plant higher than government estimates

Green Car Congress

VOCs and nitrogen oxides react with sunlight to form ground-level ozone, the main component of smog. Over the past decade, because of the renewable fuel mandate, we have added 10 percent of ethanol to all the gasoline that is sold in the U.S. and so the question is: what does that do to the environment. —Joost de Gouw.

Study: air pollution causes 800,000 extra deaths a year in Europe and 8.8 million worldwide

Green Car Congress

Using a new method of modeling the effects of various sources of outdoor air pollution on death rates, the researchers found that it caused an estimated 790,000 extra deaths in the whole of Europe in 2015 and 659,000 deaths in the 28 Member States of the European Union (EU-28). million deaths in 2015. They focused particularly on PM 2.5

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

As with the earlier assessment, this study consists of two separate, but related, analyses: greenhouse gas emissions from 2015-2050, and air quality impacts in 2030. In the Lower GHG scenario, in 2050, total emissions for the electricity and transportation sectors could be reduced by 2610 million metric tons relative to 2015 levels.

ARB posts discussion draft of new proposed mobile-source emissions reduction strategy through 2030; Advanced Clean Cars 2 regulation

Green Car Congress

ARB staff developed this strategy using a multi-pollutant scenario planning tool ( Vision 2.0 ) that quantifies changes in ozone and PM 2.5 The electrical grid and hydrogen supply supporting these electric vehicles will need to represent 50% renewable energy generation. Vision 2.0 Projected statewide light duty vehicle technology mix.

California Air Resources Board adopts GHG cap-and-trade program; first auctions slated for Aug/Nov 2012

Green Car Congress

The cap-and-trade joins a suite of other major climate program measures including standards for ultra-clean cars (Advanced Clean Cars, earlier post ), low-carbon fuels (Low Carbon Fuel Standard, earlier post ) and renewable electricity. the second, starting in 2015, brings in distributors of transportation fuels, natural gas and other fuels.

Calif. ARB releases GHG scoping plan update; more ZEVs, ā€œLEV IVā€, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. However, to achieve the needed transportation GHG reductions and the corresponding 2032 ozone standards, the market uptake of advanced technologies will need to be accelerated.
