Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

NOAA greenhouse gas index continues climbing; 1.29 in 2010

Green Car Congress

Started in 2004, the AGGI reached 1.29 It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases. NOAA researchers developed the AGGI in 2004 and have so far back calculated it to 1978. in 2010—i.e.,

Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

The monsoon is one of the most powerful atmospheric circulation systems on the planet and it happens to form right over a heavily polluted region. This could explain satellite measurements showing high levels of stratospheric ozone, water vapor and other chemicals over Asia during summer.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, 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. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.

Losses of tropical and temperate mountain glaciers affecting perhaps 20-25% of the human population in terms of drinking water, irrigation and hydro-power. The developing and least-developed economies, 80% of the world’s population, accounted for 73% of the global growth of emissions in 2004. Global emissions were growing by 1.1%
