Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

In climate models, if you simulate the world with sulfur emissions from shipping, and you simulate the world without these emissions, there is a sizable cooling effect from changes in the model clouds due to shipping. The calculated concentration of cloud droplets without emissions along the shipping route (yellow line).

WHO report urges greater attention to improved land use, rapid transit, cycling and walking to achieve health co-benefits from transport GHG emissions mitigation

Green Car Congress

Among strategies to reduce CO 2 emissions in the transport sector, a shift to active transport (walking and cycling) and rapid transit/public transport combined with improved land use can yield much greater immediate health “co-benefits” than improving fuel and vehicle efficiencies, according to a new WHO (World Health Organization) report.

Devil in the Details: World Leaders Scramble To Salvage and Shape Copenhagens UNFCCC Climate Summit

Green Car Congress

At issue is the 2012 expiration of the Kyoto Protocol, a binding but effectively unenforceable 1997 treaty that had set greenhouse gas (GHG) emission reduction targets for 40 industrialized countries, referred to as Annex 1 countries, yielding an average GHG reduction of 5.2% ” [ 1 ].

PwC analysis finds meeting 2 C warming target would require “unprecedented and sustained” reductions over four decades

Green Car Congress

The low annual rate of global reduction of carbon emissions per unit of GDP needed to limit global warming to 2 °C—based on the probability assessments of the UN IPCC—is insufficient to achieve that goal, according to the latest Low Carbon Economy Index published by business consultancy PwC. per year through 2050.
