Here's a look at the goals by country:
Britain: The U.K. said Wednesday that it would ban sales of new gasoline and diesel cars starting in 2040 as part of a bid to clean up the country's air.
By 2050, all cars on the road will need to have zero emissions.
"We can't carry on with diesel and petrol cars," U.K. environment secretary Michael Gove told the BBC. "There is no alternative to embracing new technology."

Nearly 2.7 million new cars were registered in the U.K. in 2016, making it the sixth biggest market for car sales in the world.
Stephanie Brinley, senior autos analyst at IHS Markit, said getting rid of gas-guzzling cars would be difficult. But if politicians are serious, manufacturers will have to respond.
"The big automakers are highly unlikely to just abandon the market," she said. "They'll find a way."
France: The government announced earlier this month that it wants to end sales of gas and diesel-powered vehicles by 2040 as it fights global warming.
After that date, automakers will only be allowed to sell cars that run on electricity or other cleaner power. Hybrid cars will also be permitted.
Nicolas Hulot, the government official in charge of France's "ecological transition," said the goal would help the nation's automakers "innovate and become market leaders."
The share of cars powered by electric, hybrid and alternative fuels in France is small -- about 4% -- but growing fast. Sales of those vehicles were up 25% in the first quarter of 2017.
India: New Delhi said earlier this year that every vehicle sold in the country should be powered by electricity by 2030.
"This is an aspirational target," said Anil Kumar Jain, a government energy adviser. "Ultimately the logic of markets will prevail."
India, which suffers from an especially acute air quality problem, is home to many of the world's most polluted cities.

But it's also a country where policy can make a big difference.
The number of cars on the country's roads is expected to explode over the coming years as four-wheel vehicles become more affordable for the middle class.
If families purchasing a car for the first time are able to buy electric, the country could leapfrog ahead of some developed economies.
Norway: The government's transportation plan outlines a clear target: All new passenger cars and vans sold in 2025 should be zero-emission vehicles.
The country is considered a leader in this area. About 40% of all cars sold in the country last year were electric or hybrid vehicles.

The others: At least 10 other countries have electric car sales targets in place, according to the International Energy Agency.
Austria, China, Denmark, Germany, Ireland, Japan, the Netherlands, Portugal, Korea and Spain have set official targets for electric car sales. The United States doesn't have a federal policy, but at least eight states have set out goals.
China -- which buys more cars than any other country -- is also the largest electric car market. China accounts for more than 40% of the electric cars sold in the world and more than double the number sold in the U.S., according to the IEA.
The IEA report contains an alarming statistic that shows just how far many other countries have to go:
Globally, 95% of electric cars are sold in only 10 countries: China, the U.S., Japan, Canada, Norway, the U.K., France, Germany, the Netherlands and Sweden.
