Most major countries are finding that it’s easier to promise to fight climate change than to actually do it
Entre o 10 biggest carbon emitters, only the europeu Union has enacted polices close to or consistent with international goals of limiting warming to just a few more tenths of a degrees, according to scientists and experts who track climate action in countries.
But Europe, which is broiling through a record-smashing heat wave and hosting climate talks this week, also faces a short-term winter energy crunch, which could cause the continent to backtrack a tad and push other nations into longer, dirtier energy deals, especialistas disseram.
“Even if Europe meets all of its climate goals and the rest of us don’t, we all lose,” said Kate Larsen, head of international energy and climate for the research firm Rhodium Group. Emissions of heat-trapping gases don’t stop at national borders, nor does the extreme weather that’s being felt throughout the Northern Hemisphere.
“It’s a grim outlook. There’s no getting away from it, Estou com medo,” said climate scientist Bill Hare, CEO of Climate Analytics. His group joined with the New Climate Institute to create the Climate Action Tracker, which analyzes nations’ climate targets and policies compared to the goals of the 2015 Acordo de Paris.
The tracker describes as “insufficient” the policies and actions of the world’s top two carbon polluters, China and the U.S., as well as Japan, Saudi Arabia and Indonesia. It calls Russia and South Korea’s polices “highly insufficient,” and Iran comes in as “critically insufficient.” Hare says No. 3 emitter India “remains an enigma.”
“We are losing ground against ambitious goals” such as keeping global warming to less than 2 graus Celsius (3.6 graus Fahrenheit) ou 1.5 Celsius (2.7 graus Fahrenheit) since pre-industrial times, said veteran international climate negotiator Nigel Purvis of Climate Advisers. The world has already warmed 1.1 graus (2 graus Fahrenheit) since pre-industrial times.
Seven years ago, when almost all the nations of the world were preparing for what would become the Paris climate agreement, “it was all about ambition and setting ambitious targets,” Larsen said. “Now we are transitioning into a new phase that’s really about implementation … I don’t think the international community knows how to do implementation.”
Other nations and the United Nations can pressure countries to set goals, but enacting laws and rules is a tougher sell. While Europe has been successful with “a long history of implementing and ratcheting up existing policies,” Larsen said, that’s not the case in the United States. Os EUA. is on path to cut emissions by 24% para 35% abaixo de 2005 levels by 2030, far shy of the nation’s pledge to reduce emissions by 50% para 52% in that time, according to a new analysis by Rhodium Group.
Biden is running low on options, said Larsen, a report co-author. Congress — specifically key Sen. Joe Manchin of West Virginia — is balking on the president’s climate-fighting legislation, and the Supreme Court curbed power plant regulations.
Congressional action “was a big window of opportunity that would have allowed us to be on track to our goal,” Larsen said. A second window is available in “the suite of federal regulations that the Biden administration plans to release.”
“These are the two big deciders of whether the U.S. will meet its target, and one we have largely failed on. So in that sense, it is a big miss because these opportunities don’t come along very often," ela disse.
"Os EUA. can get close” to reaching its goal, but it’s not close yet, Larsen said. Whether that happens “depends on the next three to 18 months of what the administration does.”
Other nations, particularly China, look at what the U.S. is doing to fight climate change and are reluctant to ratchet up their efforts if America isn’t doing much, Purvis and Hare said.
At the urging of activists and some Democrats, the Biden administration is considering declaring a national emergency because of climate change and using special powers to cut carbon pollution from power plants and vehicles. Calling it an emergency is not enough; what matters is the actions that follow, Purvis said.
Biden could put a moratorium on federal lands and water. He could reinstate a ban on U.S. oil exports. He could move up spending on wind and solar. But all are subject to a conservative Supreme Court.
“The big question is where can Biden go with executive orders and how convincing is that going to be to other leaders?” Hare said.
Elsewhere in the world, “the Russian energy crisis has definitely been a major setback,” Hare said. It’s a short-term problem for Europe, and it’s even loosened some of their rules, but “their long-term policy framework is very robust, and this might help them double down on alternative energy,” Larsen said.
But the panic over natural gas has other countries, specifically in Africa, jumping onto the bandwagon of liquified natural gas, which still emits carbon. The pivot to LNG has added 15% para 20% to the amount that the world uses, Hare said.
While there is a risk Europe might add infrastructure for natural gas that will be hard to abandon, it looks like the Russian invasion of Ukraine strengthened Europe’s resolve to reduce Russia’s energy influence and get off fossil fuels, Purvis said.
There are other places where weaning the world off carbon looks more possible. A new report from the International Renewable Energy Agency found the cost of electricity last year from onshore wind fell by 15%, offshore wind by 13% and solar panels by 13% comparado com 2020.
Enquanto isso, electric vehicle sales in America are rising, and the time when they could hit “escape velocity” and really make a difference is on the horizon, Larsen said.
