The future of the world, it seems, is in the hands of two men: Donald Trump and his polarising candidate, Mike Pence.
Trump, a former real estate tycoon who has made his name as a reality TV star, is seen as a more polarising figure.
But his own administration has struggled to build on the environmental gains made by his predecessor, former Vice President Joe Biden.
And, despite the polarising tone, Trump has not been accused of a lack of ambition.
This is an issue that has plagued both Biden and Trump in the past.
Biden and former President Bill Clinton both took to the stage in Washington DC on Saturday to announce ambitious initiatives to tackle climate change.
The two men were joined by former vice-president Joe Biden, who was in attendance, and US Secretary of State John Kerry, who delivered a speech.
It was a bold move by the US, but one that was criticised by both sides of the aisle.
Pence’s plan has been praised by environmental groups and some Democrats.
The environmentalist group Greenpeace said the plan was a “game changer” that would “turn America’s oceans green”.
Biden’s plan was described as a “big mistake”.
Trump has been criticised for failing to take action on climate change, including his refusal to divest from fossil fuels, and for his stance on climate policy, such as his support for the Keystone XL pipeline, which would have carried Canadian tar sands oil to the US Gulf Coast.
Trump and Pence’s plans have not gone down well with environmentalists, many of whom have criticised their plan as “dangerous”.
A coalition of environmental groups has called for a boycott of the Republican ticket.
Environmentalists say the US needs to move towards a “carbon neutral” economy and avoid the “danger of an ever-escalating carbon pollution bubble”.
“We are at the tipping point,” environmentalist Matt Ridley said.
A Trump administration has also been criticised in recent months for a lacklustre response to climate change and for not following through on environmental commitments made by its predecessor. “
He needs to say that we’re going to move away from oil and gas extraction and toward a carbon-neutral economy.”
A Trump administration has also been criticised in recent months for a lacklustre response to climate change and for not following through on environmental commitments made by its predecessor.
A report by the nonpartisan Intergovernmental Panel on Climate Change (IPCC) found that Trump’s administration was lagging behind in its efforts to reduce greenhouse gas emissions, despite having been sworn in in January.
Trump has vowed to “renegotiate” a $1tn (£700bn) deal that President Barack Obama struck with China in 2015, in which the US would curb carbon emissions, and cut its reliance on foreign oil.
Trump’s transition team has denied that the administration is taking a climate change approach.
A spokesman for Trump’s White House, Hope Hicks, said that the US “has been a leader on this issue” but that Trump had “made no promises on the climate”.
The Republican ticket has also criticised the Trump administration for its handling of climate change issues, saying that it has been too lenient on developing countries, including China.
