His new 10 point plan will aim, among other things, to get gasoline and diesel vehicles off the road by 2030, harness greener energy sources and protect nature.

United States: Joe Biden will have to unravel Trump’s climate damage before making progress
By Cordelia Lynch, American correspondent
The UK has always has presented itself as a world leader in the fight against climate change, but Mr. Biden is also on a mission, with the most ambitious climate agenda ever adopted by a US president.
He called the climate crisis an “existential threat” to America and presented a $ 2 billion plan to decarbonize the electricity sector and create millions of clean energy jobs.
Mr. Biden says his goals would be to see the US energy sector become carbon-free by 2035. That would allow the country to become a net zero emitter by 2050.
It also wants to revolutionize transportation using electric vehicles and trains, and build 1.5 million sustainable homes and homes. But none of the above will be easy.
Donald Trump spent the past four years denying the existence of climate change and trying to remove what he sees as barriers to efficient energy production.
It has struck down 160 environmental regulations, covering everything from automotive fuel standards to methane emissions to light bulbs.
Thanks to its support for fracking, the United States briefly became the world’s largest oil exporter. His passion for fossil fuels, oil and gas production put America back on its previous path to a greener future.
Other countries, including the UK, have done much better. Mr. Biden has a lot to unravel and unravel.
China: world’s biggest polluter splashes green money – but the reality is much different
By Tom Cheshire, Asia Correspondent
China is the biggest polluter in the world – much bigger than Britain. Its total carbon emissions are 27 times that of the UK, according to the Union of Concerned Scientists, a US non-profit organization.
When it comes to an elephant and a mouse, is the mouse climate change strategy even worth shouting about?
Yes, for several reasons.
First, the UK and China aren’t that far apart when you remember that China has 1.4 billion people.
According to the World Bank, its per capita CO2 emissions are 7.2 tonnes, not far from the UK’s 5.8 – and well below the US figure of 15.5.
The West is not as green as one would like to think and we have a duty to act, regardless of what China does.
Chinese leaders, like those in the UK, are actually taking climate change seriously.
They’ve invested more than any country in renewables, built an electric car industry, and have publicly committed to being carbon neutral by 2060 (not quite the same as ‘climate’ neutrality). , which refers to all greenhouse gases, not just carbon), with emissions peaking by 2030.
Reality, however, has a way of intruding.
Beijing spent the past week shrouded in the sweltering smog that locals thought was a thing of the past because it was out of balance COVID-19[feminine[feminine recovery depends on heavy industry rather than greener shoots.
Beijing must stay the course on climate change. Commitments from other countries, even if they are much smaller like the UK, are one way to keep China honest.
India: rampant growth and aspiration to the middle class slow climate action
By Neville Lazarus, Indian journalist
According to a report by Greenpeace and the Center for Research on Energy and Clean Air (CREA), Inde continues to rank first as the worst sulfur dioxide (SO2) emitter for the fifth consecutive year.
It emits 21% of the world’s SO2, nearly double the Russia, which is the second worst country.
SO2 is a toxic air pollutant that increases the risk of stroke, heart disease, lung cancer and premature death.
Air pollution is the cause of 12.5% of deaths nationwide.
During the winter months, a thick layer of smog envelops northern India, especially the capital Delhi, where air pollution is nearly 10 times the level recommended by the World Health Organization.
Environmentalists say the cause of this is almost entirely human-made. Farmers set the stubble that was left over after harvest on fire because it is too expensive to dispose of otherwise.

There is very little government financial support for the farmer to change the disposal method.
In the past month, the state of Punjab has recorded nearly 74,000 farm fires.
The government tried to criminalize this, even fining farmers, but it backfired because it is a big voting bank. No government would want to upset them.
Thermal power plants are also the main cause of SO2 emissions. Although renewable energy capacity is increasing in the country, most coal-fired power plants do not have the technology to clean up sulfur emissions.
With one of the largest middle class populations in the world, the government strives to strike a balance between people’s aspirations and the environment.
Although the prime minister Narendra ModiThe government has pushed new initiatives in the field of renewable energies, the gains have been canceled by other facets of the unbridled and above all random growth of the country.
