Volvo ends 45-year relationship with the diesel amid shift to EVs
By 2030, Volvo aims to be an electric-only brand. Which is a major shift considering that in the 2010s the vast majority of the cars the automaker sold in Europe were diesels......»»
Curbside collection improves organic waste composting, reduces methane emissions
Most organic household waste ends up in landfills, where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming......»»
Researchers harness the sun to produce hydrogen gas from water
A team of chemistry researchers at the University of North Carolina at Chapel Hill has developed a unique approach to harnessing the sun's energy to produce hydrogen gas, a potential clean energy source, from water, according to a paper published in.....»»
New study reveals influencers of global biogenic volatile organic compound emission trends over the last 20 years
Biogenic volatile organic compounds (BVOCs) emitted by vegetation are important precursors of ozone and secondary organic aerosols in the atmosphere, affecting air quality, clouds, and climate. However, BVOC emissions remain highly uncertain because.....»»
BYD targets EV laggards Toyota, VW with latest price cuts
BYD is discounting almost every electric and hybrid model it sells in China as part of a marketing campaign declaring “electricity is cheaper than oil.”.....»»
Tim Cook says Apple recycling already depends on AI
Speaking at a Chinese conference on reducing carbon emissions, Tim Cook has revealed that Apple is already using AI to help with its moves to be carbon neutral and specifically around how it recovers and recycles materials.Tim Cook (Credit: Apple)Coo.....»»
Droughts in Europe could be avoided with faster emissions cuts
Rapid climate action could mean devastating dry periods in the Mediterranean become less frequent by the end of the century, a new study shows......»»
EPA compromises with auto industry on vehicle emissions rule
Amid industry backlash that initial requirements were unachievable in the six-year time frame, the EPA alleviated some of the pressure......»»
Stellantis emissions deal with California adds clarity for dealers
Stellantis previously said it had to limit shipments of gasoline vehicles in 14 states because it wasn't allowed to join a 2020 deal California reached with other major automakers......»»
Research team introduces superaerophobic three-dimensional nickel catalysts for accelerated water electrolysis
Water electrolysis process is a system that produces hydrogen by electrolyzing water. It is an eco-friendly technology that can produce hydrogen fuel, a future energy source, without emitting environmental pollutants, but its limitations include low.....»»
Scientists develop catalyst designed to make ammonia production more sustainable
Ammonia is one of the most widely produced chemicals in the world, and is used in a great many manufacturing and service industries. The conventional production technology is the Haber-Bosch process, which combines nitrogen gas (N2) and hydrogen gas.....»»
New EPA, DOE fuel regs give automakers longer to reduce CO2 emissions
The model-year 2032 standards are still strict, but there's a more gentle ramp-up. Enlarge (credit: Aurich Lawson | Getty Images) This week, the US Department of Energy and the Environmental Protection Agency have publi.....»»
Researcher investigates the impact of local climate change beliefs and policy
In two newly published papers, Tom Lyon, professor of business economics and public policy, explores the effect of sentiment and policy on greenhouse gas emissions. Lyon and his collaborators found that community concerns and policy actions can signi.....»»
Scientists find one of the most ancient stars that formed in another galaxy
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your ve.....»»
EPA eases ramp-up for vehicle emissions rule to address industry concerns
EPA now sees battery-electric vehicles at 30 to 56 percent of light-vehicle sales in 2030-32 model years, down from the controversial 67 percent in 2032 in its original proposal......»»
To appease industry concerns, EPA eases stringency ramp-up in vehicle emissions rule
EPA now sees EVs at 30 to 56 percent of light-vehicle sales in 2030-32 model years, down from the controversial 67 percent in 2032 in its original proposal......»»
People Hate the Idea of Car-Free Cities—Until They Live in One
Removing cars from urban areas means lower carbon emissions, less air pollution, and fewer road traffic accidents. So why are residents so resistant?.....»»
Study demonstrates spontaneous self-organization of microdroplets through quasi one-dimensional confinement
Polymer systems composed of multiple components can spontaneously induce emulsion or microdroplets by mechanical mixing, as an intermediate state of macroscopic phase separation. Unfortunately, the size of generated droplets is nonuniform and their s.....»»
Greenhouse gas emissions in Global South countries are linked with International Monetary Fund lending policies
Greenhouse gas emissions significantly increase in countries in the Global South within a few years after initially borrowing from the International Monetary Fund using structural loans, but not when more flexible lending conditions are involved......»»
The Honda CR-V e:FCEV is a plug-in fuel-cell hybrid nobody asked for
Hydrogen has problems, and this isn't a solution, but it's a decent CR-V. Enlarge / We still think hydrogen fuel cells make more sense for static generators like the ones in the background, but Honda decided to make a fuel cell-p.....»»
