Report finds says “negative emissions technologies” need to play a large role in mitigating climate change

Green Car Congress

To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.

U-Mich researcher’s first-principles analysis challenges conventional carbon accounting for biofuels; implications for climate policy

Green Car Congress

System boundaries (red line) schematic for liquid fuel carbon balance. For biofuels, because biogenic carbon is automatically credited within a product lifecycle, the boundary effectively excludes vehicle end-use CO 2 emissions. In a paper that could have a significant impact on climate policies for transportation fuels, Dr. John M.

Bosch on importance of renewable synthetic fuels to reach climate goals; e-fuels

Green Car Congress

Then add carbon. Climate neutrality. Vehicles on the road, when powered by synthetic fuel, are ultimately climate-neutral. Present studies suggest that a pure fuel cost of between €1.20 Combustion engines powered by carbon-neutral synthetic fuels are therefore a crucial path to explore. Finally, combine CO?

USDA and Blue Biofuels collaborate to optimize yields of king grass for cellulosic ethanol production

Green Car Congress

The growth of a perennial grass biomass crop can add additional profit opportunities for Florida and to other parts of the US with climates suitable for tropical biomass production. The trials will be set up to allow for public presentations and publications. Sugars are subsequently processed into biofuels.

Bosch, Shell, and Volkswagen develop renewable gasoline with 20% lower CO2; rollout of Blue Gasoline this year

Green Car Congress

Following on the introduction of R33 Blue Diesel ( earlier post ), Bosch, Shell, and Volkswagen have now developed a low-carbon gasoline. The new fuel, called Blue Gasoline, similarly contains up to 33% renewables, ensuring a well-to-wheel reduction in carbon emissions of at least 20% per kilometer driven. Every bit of CO?

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. The identified measures complement, but do not replace, anticipated carbon dioxide reduction measures.

Study finds emissions from road construction could be halved using today’s technology

Green Car Congress

It was one of the Swedish Transport Agency’s first projects in which a complete climate calculation was made. All the materials and activities involved in its construction were calculated for their total climate impact: energy and materials used in the construction and what emissions these contribute to.
