Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Estimated attribution of fuel savings due to fuel economy improvements to light-duty vehicles since 1975.

IIASA: removing fossil fuel subsidies will not reduce CO2 emissions as much as hoped

Green Car Congress

However, the study found that the growth of CO 2 emissions by 2030 would only be 1-5% lower than if subsidies had been maintained, regardless of whether oil prices are low or high. The largest effects of removing subsidies were found in areas that export oil and gas, such as Russia, Latin America, and the Middle East and North Africa.

Global CO2 emissions up 3% in 2011; per capita CO2 emissions in China reach EU levels

Green Car Congress

savings stimulated by high oil prices led to a decrease of 3% in CO 2 emissions in the European Union and of 2% in both the United States and Japan. The United States remain one of the largest emitters of CO2, with 17.3 At 3%, the 2011 increase in global CO 2 emissions is above the past decade’s average annual increase of 2.7%.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

CCTF will only employ direct CO 2 capture from air when the CO 2 emission price exceeds the cost of air capture. At sufficiently high oil prices, CCTF will always displace CCS, but from a climate perspective, CCTF (without air capture) is clearly not a replacement for CCS.

US EIA Projects World Energy Use to Grow 44% Between 2006 and 2030, CO2 Emissions Up by 39%

Green Car Congress

With strong economic growth and continued heavy reliance on fossil fuels expected for most of the non-OECD economies, much of the increase in carbon dioxide emissions is projected to occur among the developing, non-OECD nations. World oil prices have fallen sharply from their July 2008 high mark. in the reference case.

Annual Increase in Global CO2 Emissions Halved in 2008; Decrease in Fossil Oil Consumption, Increase in Renewables Share

Green Car Congress

In addition to high oil prices and the financial crisis, the increased use of new renewable energy sources, such as biofuels for road transport and wind energy for electricity generation, had a noticeable and mitigating impact on CO 2 emissions. Global CO2 emissions increased from 15.3 Source: PBL. Click to enlarge.
