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 On-Road Transportation Sector the Greatest Net Contributor to Atmospheric Warming Now and in Mid-Term; Power Sector Takes the Lead by 2050

Green Car Congress

In contrast, the industrial and power sectors release many of the same gases—with a larger contribution to radiative forcing—but they also emit sulfates and other aerosols that cause cooling by reflecting light and altering clouds. “We Targeting on-road transportation is a win-win-win. Unger et al.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The University of Bremen is the scientific base of the international project known as EMeRGe (Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scales).

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. Transportation. Background.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. However, the underlying estimates do not take into account economic benefits of reduced climate change.

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

Green Car Congress

Temperature change per transport work by mode for various years after the emissions: per passenger kilometer for passenger travel (left) and per ton-kilometer for freight transport (right). Passenger travel with rail, coach or two- and three-wheelers has on average the lowest specific climate impact also on short time horizons.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?
