Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. —Mark Jacobson. In both plants, natural gas turbines power the equipment.

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

Green Car Congress

Substantial emission reductions due to fuel economy standards for passenger cars are already included in the current policy scenario. A large part of this potential comes from six relatively standardized categories: solar and wind energy; efficient appliances; efficient passenger cars; afforestation and stopping deforestation.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

PCAST suggests 6 key components for climate change strategy to President Obama; adaptation and mitigation

Green Car Congress

The President’s Council of Advisors on Science and Technology (PCAST) released a letter to President Obama describing six key components the advisory group believes should be central to the Administration’s strategy for addressing climate change. Both approaches are essential parts of an integrated strategy for dealing with climate change.

Berkeley study finds renewable portfolio standards insufficient to meet 2030 GHG emission targets; new policy required

Green Car Congress

The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers.
