‘We have to step up’: Biden commits to slashing greenhouse gas emissions by 50% by 2030

World

The US will commit to halving its greenhouse gas emissions by 2030, Joe Biden is set to announce.

It comes as the US president will speak to other world leaders, including Boris Johnson, at a global climate summit held at the White House on Thursday.

The pledge – which amounts to nearly doubling previous commitments – and the summit represent a concerted US effort to reclaim credibility and leadership on climate change after four years of inaction under Donald Trump.

‘Smoke, noise and plenty of fumes’

Among measures which could be employed to reduce emissions by 50% to 52% are a “carbon border adjustment” – or carbon tariff – that would tax imports from countries that do not have similar emissions controls.

The White House could also target the biggest emitting sectors – including ensuring zero emissions from power plants by 2035, boosting energy efficiency in homes and businesses, incentives for electric vehicle use and expanding “carbon sinks” like forests and agriculture.

The target is based on 2005 levels of emissions.

A Biden administration official said: “We see multiple paths to reaching this goal.”

US Republicans say the target could damage the economy, with job cuts expected to come from areas such as power plants and the automotive industry.

Sector-specific goals will be revealed later in the year, but the administration has already moved to introduce a $2 trillion infrastructure plan, that could help Mr Biden deliver the emissions cuts he needs, including a clean energy standard.

However, he will need the US Capitol on his side before he can make the sweeping changes he’s pledged.

Prime Minister Boris Johnson will tell the gathering that 2021 will be the year for countries to “get serious” over climate change, having already announced that the UK will aim to cut its own emissions by 78% by 2035.

The UK will also host COP26 talks in Glasgow later in the year.

China is also in attendance at the summit, as well as Canada, India and Brazil, with all nations under pressure to pledge more action on climate change, to ensure global warming does not go beyond the 1.5C goal.

Sky News broadcasts the first daily prime time news show dedicated to climate change.

Hosted by Anna Jones, The Daily Climate Show is following Sky News correspondents as they investigate how global warming is changing our landscape and how we all live our lives.

The show will also highlight solutions to the crisis and show how small changes can make a big difference.
