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. Their paper is published in the journal Energy Policy. Greene et al. has almost doubled. —Greene et al.

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.

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

Green Car Congress

Weak economic conditions, a mild winter, and energy. 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 of all energy. tonnes per capita.

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

In both the base-case and a scenario with more aggressive environmental policies, CO 2 emissions from energy use remain well above the IEA 450 scenario. Non-OECD countries are seen to rapidly increase their share of overall energy demand from just over half currently to two-thirds. Click to enlarge. per year.

Researchers show mixotrophic fermentation process improves carbon conversion, boosting yields and reducing CO2

Green Car Congress

The production costs for most chemicals via microbial fermentation are currently high compared to oil-derived products primarily because of operating costs associated with feedstock and feedstock processing. One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. Jones, Alan G. Fast, Ellinor D.
