NASA-led study identifies unprecedented depletion of stratospheric ozone layer above Arctic

Green Car Congress

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

California ARB releases final version of proposed update to Climate Change Scoping Plan; LEV IV

Green Car Congress

the final version of the proposed First Update to the Climate Change Scoping Plan (First Update). Achieving our long-term climate goal and 2032 ozone standards will require a much deeper penetration of ZEVs into the fleet. The California Air Resources Board (ARB) has released. The draft version was released in February.

Study finds climate impact of long distance trip can vary by factor of 10 depending upon mode, efficiency and occupancy

Green Car Congress

GWP100 weighted specific climate impact (g CO 2 -eq per pkm) as a function of vehicle occupancy. A team from Austria and Norway has found that the climate impact from a long-distance trip (500–1,000 km, or 310–621 miles) can easily vary by a factor of 10 per passenger depending on mode choice, vehicle efficiency, and occupancy.

Study Finds Traveling by Car Increases Global Temperatures More than Traveling by Plane In the Long Term

Green Car Congress

A new study comparing both the absolute and normalized climate impacts of current passenger and freight transportation finds that driving a car increases global temperatures in the long run more than making the same long-distance journey by air.

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.
