Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1

Study estimates global black carbon emissions up 72% from 1960-2007; BC emissions intensity down 52%

Green Car Congress

Black carbon emissions and BC emissions intensity per year. A study led by a team from Peking University has estimated that global black carbon (BC) emissions increased from 5.3 teragrams per year in 2007 (+72%). Black carbon has two deleterious effects on the environment. Credit: ACS, Wang et al. Click to enlarge.

Copenhagen Diagnosis Released, Detailing Accelerating Indicators of Climate Change In Last Three Years

Green Car Congress

A team of 26 climate scientists from Australia, Austria, Canada, France, Germany, Switzerland, the United Kingdom, and the United States have published the “Copenhagen Diagnosis”, an interim synthesis report on developments in climate change science from mid-2006 to the present day.

New modeling study finds thawing permafrost could release vast amounts of carbon and accelerate climate change by the end of this century

Green Car Congress

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates. Units are in grams of carbon per square meter per year. Click to enlarge.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

If a cap-and-trade program includes offsets, regulated entities have the opportunity to purchase the “emission credits” generated by carbon offset projects to help them meet their compliance obligations. In this way, offsets would complement the more traditional emissions trading that can occur between two covered sources.

Perspective: The UN Approval Process for Carbon Offsets

Green Car Congress

Since 2005, when major greenhouse-gas emitters among the Kyoto signatories were issued caps on their emissions and permitted to buy credits to meet those caps, there has been more than $300 billion worth of carbon transactions. The approval process for carbon offsets has two goals. THE APPROVAL PROCESS.
