IEA: global carbon dioxide emissions have rebounded strongly

Green Car Congress

The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data, but the overall decline of about 6% masks wide variations depending on the region and the time of year. Emissions in the United States fell by 10% in 2020.

Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. billion in 5 years while reducing overall UK emissions by 2.9%. If implemented in the UK alone, the system could deliver cost savings of £1.28

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Study finds transporting food and ingredients generates 20% of carbon emissions in the global food system

Green Car Congress

A study by researchers in Australia and China has determined that global food-miles account for nearly 20% of total food-systems emissions; moving fruit and vegetables in refrigerated vehicles is particularly emissions-intensive. We estimate the carbon footprint of food-miles by using a global multi-region accounting framework.

New Fraunhofer membrane technology enables co-transport of hydrogen and natural gas

Green Car Congress

Researchers at the Fraunhofer-Gesellschaft have developed a membrane technology for the energy-efficient and economic separation of hydrogen from natural gas. This technology makes it possible for the two substances to be routed through the national natural gas grid together and then isolated from one another at their final destination.

EIA: California drought will decrease hydropower, increase natural gas use and CO2 emissions

Green Car Congress

EIA expects that level of decrease in hydropower generation would lead to an 8% increase in California’s electricity generation from natural gas, a 6% increase in energy-related carbon dioxide (CO 2 ) emissions in the state, and an average 5% increase in wholesale electricity prices throughout the West given the current system configuration.

SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. g/hp-hr NO x emissions). SwRI developed the technology for the California Air Resources Board (CARB).
