The growing list of countries committing to a net-zero emissions goal

terça-feira, julho 02, 2019

After decades of work, scientists have finally agreed on a (relatively) simple answer to the climate crisis: Achieve net-zero greenhouse-gas emissions as soon as economically possible. The only thing that drives global warming is the total amount of heat-trapping gases in the atmosphere. (The “net-zero” part is that, in cases like air travel, we won’t have the technology to stop emitting; in those cases, we’ll need to build sinks to capture those emissions.)

This simple message was amplified in 2015, after every country in the world signed the Paris climate agreement. Since then, many large and small countries have committed to adopting a net-zero emissions goal.

Here’s the running list of such countries, compiled by the Energy and Climate Intelligence Unit. We will update the list as more countries are added or their goal status changes.

Country	Target date	Goal status
Suriname	Achieved	Already carbon negative
Bhutan	Achieved	Already carbon negative
Norway	2030	In law
Uruguay	2030	In policy document
Finland	2035	In policy document
Iceland	2040	In policy document
Sweden	2045	In law
UK	2050	In law
France	2050	In law
Spain	2050	Proposed legislation
New Zealand	2050	Proposed legislation
Germany	2050	Target under discussion
Netherlands	2050	Target under discussion
Ireland	2050	Target under discussion
Denmark	2050	In policy document
Chile	2050	In policy document
Portugal	2050	In policy document
Costa Rica	2050	In policy document
Fiji	2050	In policy document
Marshall Islands	2050	In policy document

Notable absences on that list: The United States, Australia, and the Arab states of the Persian Gulf.

Despite those missing commitments, some smaller economies within those countries and others have set themselves a net-zero emissions goal. At the state level, that group includes California, New York, and Hawaii in the US; and New South Wales, Victoria, and Queensland in Australia. At the city level, it includes New York City, Los Angeles, London, Paris, Washington DC, San Francisco, Seattle, Sydney, Boston, Stockholm, Barcelona, Copenhagen, Austin, Melbourne, Helsinki, Manchester, Oslo, Nottingham, Adelaide, Bristol, Heidelberg, and Reykjavik.

The sum total of all these economies accounts for more than 17% of the global GDP. There’s still a long way to go to align 100% of global GDP with this goal, and committing to a goal does not mean countries or regions will achieve it. But it’s a stronger climate-mitigation stance than setting no goals at all.
