Comprehensive assessment concludes black carbon second-most important human emission in warming climate

Green Car Congress

A comprehensive assessment of black-carbon climate forcing accepted for publication in the Journal of Geophysical Research: Atmospheres estimates that black carbon, with a total climate forcing of +1.1?W?m m -2 , is the second-most important human emission in terms of its climate-forcing in the present-day atmosphere.

PwC: Global Carbon Budget For 2000-2050 Could Be Exhausted By 2034

Green Car Congress

Global accounting firm PricewaterhouseCoopers has analyzed carbon emissions from 2000 to 2008 and concluded that the world’s “carbon emissions budget”, or ability to emit carbon dioxide while still maintaining a “fair chance” of limiting average global temperatures to no more than 2 ÂșC (3.6

IEA: CO2 emissions from fuel combustion rose 2.2% in 2013, below the average rate since 2000

Green Car Congress

According to the latest data released by the International Energy Agency (IEA), CO 2 emissions related to the energy sector, which is the source of nearly two-thirds of human-generated greenhouse gases, rose 2.2% Both years were below the average growth rate since 2000 of 2.5%. In absolute terms, global CO 2 emissions increased by 0.7

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. A large international team produced this first surface ozone assessment report based on all available surface observations across the globe using data from more than 4,800 monitoring stations.

Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

Shipping-induced global temperature change in 2050 using different parameterizations of Indirect Aerosol Effect (IAE). A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

In the study, the Ford team derived regional CO 2 targets for new LDVs while still providing an integrated view of the global LDV fleet—a perspective critical to the planning needs for global automotive firms. The SMP model calculates 2000?2050 They converted from an absolute amount to scale relative to 2000.
