What GHG Concentration Targets are Reachable in this Century?
(MIT Joint Program, 2013-07-26)
We offer simulations that help to understand the relationship between GHG emissions and concentrations, and the relative role of long-lived (e.g., CO2) and short-lived (e.g., CH4) emissions. We show that, absent technologies ...
The Economic, Energy, and GHG Emissions Impacts of Proposed 2017–2025 Vehicle Fuel Economy Standards in the United States
(MIT Joint Program on the Science and Policy of Global Change, 2012-07-31)
Increases in the U.S. Corporate Average Fuel Economy (CAFE) Standards for 2017 to 2025 model year light-duty vehicles are currently under consideration. This analysis uses an economy-wide model with detail in the passenger ...
Climate Co-benefits of Tighter SO2 and NOx Regulations in China
(MIT Joint Program on the Science and Policy of Global Change, 2012-10-01)
Air pollution has been recognized as a significant problem in China. In its Twelfth Five Year Plan (FYP), China proposes to reduce SO2 and NOx emissions significantly, and here we investigate the cost of achieving those ...
Shale Gas Production: Potential versus Actual GHG Emissions
(MIT Joint Program on the Science and Policy of Global Change, 2012-11)
Estimates of greenhouse gas (GHG) emissions from shale gas production and use are controversial. Here we assess the level of GHG emissions from shale gas well hydraulic fracturing operations in the United States during ...
