When climate activists look back on history, they might see 2019 as a turning point—the year when the first serious proposal to ban gasoline cars was introduced in the U.S. Congress. The Democrat-sponsored legislation would require carmakers to sell only zero-emission vehicles by 2040. While the bill is unlikely to pass in the car-centric United States any time soon, it’s part of a trend that is gaining international momentum.
The unprecedented bushfires devastating swathes of Australia have already pumped out more than half of the country’s annual carbon dioxide emissions in another setback to the fight against climate change.
Fires blighting New South Wales and Queensland have emitted a combined 306 million tons of carbon dioxide since Aug. 1, which is more than half of Australia’s total greenhouse gas footprint last year, according to Niels Andela, an assistant research scientist at NASA’s Goddard Space Flight Center in Maryland and collaborator with the Global Fire Emissions Database. That compares with the Copernicus Atmosphere Monitoring Service’s estimate of 270 million tons in just over four months.
The concentration of carbon dioxide emissions in the atmosphere reached an unprecedented level this month. Researchers at the fossil fuel giant Exxon saw it coming decades ago.
A technology that removes carbon dioxide from the air has received significant backing from major fossil fuel companies.
The European Union tightened caps on carbon dioxide from cars in a bid to accelerate the development of electric vehicles.
The European Parliament set a 37.5 percent CO2-reduction target for 2030 compared with the 2021 limit. In a vote on Wednesday in Strasbourg, France, the assembly also fixed an interim CO2-cut goal for autos of 15 percent for 2025.
As alpine permafrost thaws, new sources of decaying organic matter become available to CO2-emitting microbes. Climate scientists and their models may be underestimating this stealthy source of carbon dioxide, according to a new study.
The UK is to review its long-term target to cut climate emissions as part of global efforts to curb rising temperatures, the government has announced.
A boom in electric vehicles made by the likes of Tesla Motors Inc. could erode as much as 10 percent of global gasoline demand by 2035, according to the oil industry consultant Wood Mackenzie Ltd.
The world is in a new era of “climate change reality”, with carbon dioxide in the atmosphere reaching a symbolic threshold which it will not fall below for many generations, scientists have said.
The U.S. passed another historic marker in its energy revolution this year. In February, U.S. transportation emitted more carbon dioxide than the fossil-fuel-heavy power sector for the first time since 1978. Overall, the U.S. has seen a 25 percent drop in carbon-dioxide emissions since 2008, the Department of Energy said, a function of the rise of natural gas and smarter energy use.
