International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C

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. However, these observations are too incomplete to be used in climate models.) “ We may be underestimating the amount of black carbon by as much as a factor of four ,” Menon says.

New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. In turn, the growth of CO 2 emissions embodied in Chinese exports has slowed or reversed, while the emissions embodied in exports, such as textiles, from less-developed regions like Vietnam and Bangladesh have surged.

UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

Green Car Congress

Even if the current Nationally Determined Contributions (NDCs) are fully implemented, the carbon budget for limiting global warming to below 2 ˚C will be about 80% depleted by 2030. Given currently available carbon budget estimates, the available global carbon budget for 1.5 ˚C gigatonnes of carbon dioxide equivalent (GtCO 2 e) above the level needed to stay on the least-cost path to meeting the 2 ˚C target.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. million lives lost each year due to black carbon soot.
