أخبار الذهب:
- Biofuels policy has been a failure for the climate, new . . .
The new report points to research saying that increased production of biofuels from corn and soy could actually raise greenhouse gas emissions, largely from carbon emissions linked to clearing
- Biofuels explained Biofuels and the environment - U. S. Energy . . .
At scale, hydrogenated lipid-based biofuels production requires a significant amount of hydrogen, which if produced from fossil fuels, may increase process emissions and thus increase their carbon intensity
- Biofuels Greenhouse Gas Emissions: Myths versus Facts
Biofuels burn cleaner than gasoline, resulting in fewer greenhouse gas emissions, and are fully biodegradable, unlike some fuel additives Cellulosic ethanol has the potential to cut greenhouse gas emissions by up to 86%
- Biofuels and the Environment - US EPA
Replacing fossil fuels with biofuels has the potential to reduce some undesirable environmental impacts of fossil fuel production and use, including conventional and greenhouse gas (GHG) pollutant emissions, exhaustible resource depletion, and dependence on unstable foreign suppliers
- Do Biofuels Increase Greenhouse Gas Emissions? - Slashdot
American farming is, by far, the largest source of domestic nitrous oxide emissions already — about 50 percent If biofuel policies lead to expanded production, emissions of this enormously powerful greenhouse gas will likely increase, too
- Increased Biofuel Production May Harm Farmers and Climate . . .
Midwestern ethanol refineries are major greenhouse gas emitters, collectively releasing 17 4 MTCO2e in 2021 They also contribute air-polluting volatile organic compounds and ground-level ozone, which can cause respiratory issues
- Biofuels Policy, a Mainstay of American Agriculture, Has Been . . .
The new report concludes that not only will the expansion of ethanol increase greenhouse gas emissions, it has also failed to provide the social and financial benefits to Midwestern communities
