Europe is relaxing CO2 emission targets after receiving feedback from automakers. The industry is concerned that the present regulatory conditions are going to cost them a fortune, so the European Commission is throwing them a bone by delaying some of the financial penalties. Everything else will remain the same.
A team of researchers from Canada and the US has developed a system that quickly and efficiently converts carbon dioxide into simple chemicals via CO 2 electrolysis. The electrode architecture enables production of two-carbon products such as ethylene and ethanol at current densities just over an ampere per square centimeter.
The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%).

University of Delaware engineers have demonstrated an effective way to capture 99% of carbon dioxide from the ambient air feed to an hydroxide exchange membrane fuel cell (HEMFC) air using a novel electrochemical system powered by hydrogen. However, HEMFC performance is adversely affected by CO 2 present in the ambient air feed.
Lloyd Distinguished Service Professor in Economics, and José-Luis Cruz of Princeton University assesses the local social cost of carbon (LSCC) and how that cost aligns with the carbon reduction pledges countries made under the Paris Agreement. The price of carbon should then be set at this price, everywhere.

Construction activities have begun at an Illinois ethanol plant on a full-scale commercial project that will demonstrate industrial carbon capture and storage (ICCS). Because all of the captured CO 2 is produced from biologic fermentation, a significant feature of the project is its negative carbon footprint—i.e.,
The analysis indicates that natural carbon sinks are maintaining overall resilience despite recent signs that the carbon uptakes of specific sinks are in decline. Approximately 40-45% of carbon emissions emitted every year remain in the atmosphere, with the balance absorbed as part of the Earth’s carbon cycle. per decade.
Unlike the others, however, Audi over the past few years has embarked on a comprehensive approach to developing a range of new CO₂-neutral fuels as part of its overall strategy for sustainable, carbon-neutral mobility: Audi e-fuels. solar and wind), water and CO 2 to produce liquid or gaseous fuels with a very low carbon intensity.
On average, human activities put out in just three to five days the equivalent amount of carbon dioxide that volcanoes produce globally each year, according to Terrance Gerlach of the US Geological Survey (USGS). Gerlach used the figure of about one-quarter of a billion metric tons of volcanic carbon dioxide per year to make his comparisons.

. … Where the statute at issue is one that confers authority upon an administrative agency, that inquiry must be “shaped, at least in some measure, by the nature of the question presented”—whether Congress in fact meant to confer the power the agency has asserted. Under our precedents, this is a major questions case.
Total emissions of the six main greenhouse gases in 2010 were equivalent to 6,822 million metric tons of carbon dioxide. These gases include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.
