- Environmental sustainability of biofuels: a review
Greenhouse gas (GHG) emissions from transport have been increasing at a faster rate than from any other sector The sector relies heavily on fossil fuels, which accounted for 96 3% of all transportation fuels in 2018 Transport is also responsible for 15% of the world's GHG emissions and 23% of total energy-related CO 2 emissions To reduce
- Environmental sustainability of biofuels: a review - PMC
Biofuels are being promoted as a low-carbon alternative to fossil fuels as they could help to reduce greenhouse gas (GHG) emissions and the related climate change impact from transport However, there are also concerns that their wider deployment
- Biofuels Greenhouse Gas Emissions: Myths versus Facts
• Cellulosic ethanol has the potential to cut greenhouse gas emissions by up to 86% • Ethanol readily biodegrades without harm to the environment, and is a safe, high-performance replacement for fuel additives such as MTBE • Use of ethanol can increase emissions of some air pollutants because fossil energy is used
- Biofuels policy has been a failure for the climate, new report claims . . .
The country’s primary biofuels policy, the Renewable Fuel Standard, requires that biofuels provide a greenhouse gas reduction over fossil fuels: The law says that ethanol from new plants must
- Are Biofuels More Environmentally Friendly? The Greenhouse Gas . . .
Biofuels: ethanol and biodiesel, liquid fuels and blending components produced from biomass materials Ethanol is a renewable fuel made from corn and other plant materials whereas biodiesel is manufactured from vegetable oils, animal fats etc Ethanol accounts for more than 85% of total biofuels in the U S Lee et al showed in their retrospective analysis that there is a significant decrease
- Biofuels versus climate change: Exploring potentials and challenges in . . .
Biofuels like ethanol and biodiesel are already integrated into the energy matrices of various countries and are often promoted as more sustainable alternatives to fossil fuels, due to their ability to reduce greenhouse gas emissions (GHGs) and contribute to a low-carbon economy [43, 44] However, the effectiveness of biofuels in mitigating climate change depends on several factors, including

(GGE) per year of sustainable biofuel could be produced by 2050 • Replacing equivalent volumes of petroleum -based fuel with sustainable biofuel would result in 410 and 640 million metric tonnes (Mt) of carbon dioxide equivalent (CO 2 e) per year of life cycle GHG reductions—a total 68% –73% reduction in
