What countries emit the most net carbon dioxide? Up until now, this question has been answered by calculating the emissions of each sector in a nation’s economy via a “bottom up” approach. However, a new paper published in Earth System Science Data March 7 pilots a “top down” approach by using NASA satellite data to […]
Most of us know the service trees, and other plants, do for almost all living things on the planet by converting carbon dioxide into oxygen. Now, scientists have discovered that when carbon levels have been made artificially higher, trees adjust and ramp up their absorption while increasing their rate of photosynthesis. The findings of the […]
One major weakness of corporate net-zero plans is that they often rely on carbon offsets that promise more than they deliver. However, a new report from the Australian Industry Energy Transitions Initiative (ETI) found that five of the country’s high-emission supply chains could achieve net zero emissions by 2050 with minimal use of offsets. “With […]
In 2019, London Mayor Sadiq Khan established the world’s first 24-hour Ultra Low Emission Zone (ULEZ) in central London to protect the city’s residents from deadly air pollution. The ULEZ imposed £12.50 fines on vehicles whose emissions exceeded certain standards. Two years later, Khan expanded the zone to include inner London within the boundaries of the North and South Circular roads.
BMW, Peugeot and Renault all make popular plug-in hybrid electric vehicles (PHEVs), but are the cars as climate-friendly as they claim? Not according to a new set of on-road tests conducted by researchers who say the vehicles emit much more carbon dioxide than official measures from standard lab tests report. According to the researchers at […]
A new study using artificial intelligence (AI) to forecast global warming timelines has found that Earth will exceed the target of limiting warming to 1.5 degrees Celsius above pre-industrial levels within about 10 to 15 years, according to a press release from Stanford University. Emissions goals designed to keep warming below the more ambitious threshold […]
By Daniel Sperling California is embarking on an audacious new climate plan that aims to eliminate the state’s greenhouse gas footprint by 2045, and in the process, slash emissions far beyond its borders. The blueprint calls for massive transformations in industry, energy and transportation, as well as changes in institutions and human behaviors. These transformations […]
Concrete is the second most widely used material on Earth, behind only water. But concrete has also historically been detrimental to our environment. According to a study published in 2019, the combination of the calcination during the making of concrete, which in many locations uses coal or natural gas as the primary heat source, as […]
Most U.S. residents could both save money and reduce their greenhouse gas emissions by switching to electric vehicles (EVs). However, the savings still wouldn’t reach the people who most need them without policy changes.
