Estimates about the climate impact from biofuels vary widely based on the methodology and exact situation examined. [9] Therefore, the climate change mitigation potential of biofuel varies considerably: in some scenarios emission levels are comparable to fossil fuels, and in other scenarios the biofuel emissions result in negative emissions.
In practice, this usually means fuels that are made using carbon dioxide (CO 2) as a feedstock. Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels, which are made by chemically hydrogenating carbon dioxide, and biofuels, which are produced using natural CO 2-consuming processes like photosynthesis.

This graph assumes that all biodiesel is used in its country of origin. It also assumes that the diesel is produced from pre-existing croplands rather than by changing land use [137] A general critique against biodiesel is the land use change, which have potential to cause even more emissions than what would be caused by using fossil fuels ...
When combusted, this carbon is re-released into the atmosphere, closing the carbon cycle and making biofuels carbon neutral under some conditions. [3] First generation biofuels such as biodiesel [4] are produced directly from crops, such as cereals, maize, sugar beet and cane, and rapeseed. Second generation fuels are produced from byproducts ...
The Washington, D.C., environmental group, compared ethanol, biodiesel and renewable diesel emissions from 226 reporting plants to those of oil refineries, based on data reported to the U.S ...
Neste MY Renewable Diesel (formerly NExBTL) is a vegetable oil refining fuel production process commercialized by the Finnish oil and refining company Neste.Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems.
Turmoil in the biomass-based diesel sector, an umbrella term for renewable diesel and biodiesel, could become a roadblock to future investments in biofuels, the U.S. Energy Information ...
Strategic Biofuels LLC, a project development company, announced on Friday it plans to develop a renewable diesel plant in Louisiana that will produce up to 32 million gallons per year of ...
