EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

Royal Society Report Concludes Geoengineering and its Consequences May be the Price for Failure to Act on Climate Change; Recommendations for Plan B

Green Car Congress

It is an unpalatable truth that unless we can succeed in greatly reducing CO 2 emissions we are headed for a very uncomfortable and challenging climate future, and geoengineering will be the only option left to limit further temperature increases. Professor John Shepherd, chair of the Royal Society’s geoengineering study.

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. Black carbon Climate Change Emissions'

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) The methane and non-combustion CO 2 emissions from natural gas systems are generally process related, with normal operations, routine maintenance, and system upsets being the primary contributors.

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. 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.

Geo-engineering could be ‘our only hope’

Green Cars News

Geo-engineering technologies were found to be very likely to be technically possible and some were considered to be potentially useful to augment the continuing efforts to mitigate climate change by reducing emissions. Geo-engineering and its consequences are the price we may have to pay for failure to act on climate change.”.
