Study Finds that US Subsidies for Fossil Fuels Are Almost 2.5x Those for Renewables

Green Car Congress

US subsidies for fuels and renewable energy, 2002-2008. The study, “Estimating US Government Subsidies to Energy Sources: 2002-2008”, found that fossil fuels benefited from approximately $72 billion over the seven-year period, while subsidies for renewable fuels totaled $29 billion.

Study finds climate-influencing cirrus clouds form around mineral dust and metallic aerosols; little evidence of black carbon

Green Car Congress

Our results demonstrate that mineral dust and metallic particles are the dominant source of residual particles, while sulfate/organic particles are underrepresented and elemental carbon and biological material are essentially absent. —Cziczo et al. Cirrus clouds typically form at altitudes higher than most commercial planes fly.

New discovery of how carbon is stored in the Southern Ocean

Green Car Congress

A team of British and Australian scientists has discovered an important method of how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath. The Southern Ocean is an important carbon sink in the world—around 40% of the annual global CO 2 emissions absorbed by the world’s oceans enter through this region.

Study Finds Black Carbon a Significant Factor in Melting of Himalayan Glaciers

Green Car Congress

A team of researchers from the US and India has found that airborne black carbon aerosols, or soot, from India is a major contributor to the decline in snow and ice cover on the glaciers in the Himalayan mountains. Black carbon alone contributes at least 30% of this sum. Change in annual linear snow cover from 1990 to 2001.

Aral pilots two new lower carbon fuels in Germany; 25% less CO? compared to pure fossil fuels

Green Car Congress

It is predicted that two-thirds of transportation will remain ICE-powered in 2030, so reducing carbon emissions from fuel is key. Existing vehicles can make its contribution to achieving the climate targets—today as well as in 2030—through the fuel itself. Aral has been bp’s German retail site brand since 2002.
