Efforts to cut car, plane and ship emissions get small boost
Several countries and companies announced plans Wednesday to stop selling cars that run on gasoline or diesel over the next two decades, as part of efforts to clamp down on a significant source of planet-warming emissions.
But the impact of the measures will likely be limited since several major emitters — notably the United States and China — did not sign on, and they received a mixed response from environmental campaigners. Nations and airlines also pledged to reduce emissions from air travel.
On the sidelines of the UN climate conference in Glasgow, Scot;and, , a group of nations said Wednesday that they would work to sell only zero-emission vehicles by 2040, and no later than 2035 in leading auto markets.
While the wording of the agreement is vague, it could essentially mean switching to electric-only fleets of cars, trucks and buses — and backing off popular halfway solutions currently in use, such as hybrid vehicles, said AP.
The plan was backed by countries including Canada, Chile, Denmark, India, Poland, Sweden, Turkey and the United Kingdom. Several American states and cities also signed sign on, as did major carmakers Ford, General Motors, Mercedes Benz and Volvo.
Some companies, such as Volvo, had already pledged to even earlier targets to phase out combustion engines.
But the Brussel-based think tank Transport and Environment said the announcement needs to be backed by legally binding targets and noted the absence of major car markets such as China, the U.S., Germany and France.
German officials said the country declined to sign the agreement because it contained a footnote that would prevent the use of synthetic fuels produced with renewable energy — an option that some in the current and likely future government want to keep open.
The country has backed a proposal being considered by the European Union to end sales of gasoline-powered cars and vans by 2035.
Transportation is one of the biggest sources of greenhouse gas emissions, according to the International Energy Agency.
A recent report by the agency found the sale of new internal combustion engine cars — those that run on gasoline and diesel — needs to be phased out by 2035 to ensure the goals set in Paris in 2015 on capping global warming at 1.5 degrees Celsius (2.7 degrees Fahrenheit) can be met.
On aviation, about two dozen countries said they would work together to reduce emissions from plane travel to “net zero” by 2050, including by promoting the use of sustainable fuels. “Net zero” means producing only as many emissions as can be absorbed again through natural or artificial means
Separately, 20 airlines announced plans to use planes powered with electric, hydrogen or hybrid engines on 30% of the fleet used for short-haul flights by 2030.
Among the signatories were Air New Zealand, Alaska Airlines, easyJet and Southern Airways Express, operating more than 800 aircraft with over 177 million passengers a year.
And major maritime industry representatives pushed Wednesday for more funding for research into clean ship propulsion technology.
The flurry of announcements on transport emissions follows a pattern at this year’s climate talks, which have seen host Britain present side deals that aren’t part of the official negotiations — a practice criticized by some environmental campaigners.
