Study Finds Current Swedish Biofuels Offer Major Climate Benefits; Biogas from Manure the Best

Green Car Congress

Biogas produced from manure, waste from food industries, and organic household waste were found to provide a climate benefit of 148%, 119% and 103%, respectively, compared to fossil fuels. Tags: Biodiesel Biomethane Climate Change Ethanol Europe. Co-production of biogas and ethanol from wheat was also analyzed.

New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions. The team then computed the impacts on health, crops and climate. Five of the 11 markets that we looked at, Brazil, China, the EU, India, and the US, produced 90% of that.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols. The HALO research aircraft is a joint initiative of German environmental and climate research institutions.

ICCT study finds that transitioning to low-GWP MAC refrigerants in China could avoid up to US$150B in costs

Green Car Congress

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.

Sponsors of SAE Study Conclude HFO-1234yf Can Be Used As Low-GWP Global Replacement Refrigerant in MAC Systems

Green Car Congress

HFO-1234yf is a non-Ozone Depleting Substance with a Global Warming Potential (GWP) of 4. The results from the CRP1234 programs that investigated the new refrigerant for use in mobile air conditioning systems (cars and light trucks) are available on-line.

The New Supersonic Boom

Cars That Think

On 9 April 1945, less than a month before the end of hostilities in Europe, a young Luftwaffe pilot named Hans Guido Mutke put his jet-propelled Messerschmitt Me 262 fighter-bomber into a steep dive, intending to come to the aid of a fellow airman below. The last of these issues was perhaps the most vexing, prompting the U.S.

Volkswagen to use CO2 as refrigerant for future air conditioning systems

Green Car Congress

(R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. With its GWP of 1, it is also the refrigerant that has the least impact on climate. CO 2 is an A1 refrigerant, indicating minimal toxicity and non-flammability. transition to a new refrigerant is not easy.
