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. gasoline demand would have put upward pressure on world oil prices.

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 Including hydropower, total renewable energy sources presently supply 8.5% tonnes per capita.

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

Green Car Congress

Removing fossil fuel subsidies would have only a small effect on CO 2 emissions and renewable energy use, according to a new study led by the International Institute for Applied Systems Analysis (IIASA) and published in the journal Nature. In addition, subsidy removal would not boost renewable energy use significantly, the team found.

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.

BP Energy Outlook 2030 sees emerging economies leading energy growth to 2030; global CO2 emissions from energy well above IEA 450 scenario

Green Car Congress

According to the base case forecast, diversification of energy sources increases and non-fossil fuels (nuclear, hydro and renewables) are together expected to be the biggest source of growth for the first time. Oil, excluding bio-fuels, will grow relatively slowly at 0.6% The fuel mix changes over time, reflecting long asset lifetimes.
