Marrakech: UN climate talks open on Monday against the backdrop of a US election that could have a major impact on America's role in the global agreement to reduce greenhouse gas emissions.
Given Hillary Clinton and Donald Trump's diverging views on climate change and the landmark emissions pact adopted in Paris last year, some countries' delegates have been unusually blunt about their preferred outcome.
Brazilian Environment Minister Sarney Filho told reporters in a conference call Thursday he believes American society supports climate action regardless of who becomes the next president. "However, on a personal note, I hope Trump doesn't win," he added.
Clinton backs the climate policies of President Barack Obama's government, including continued engagement in the Paris Agreement. Trump, meanwhile, has expressed doubts about global warming on social media and said in a speech this year that he would "cancel" the climate deal if elected.
Those comments have raised concerns in other countries about whether the US would ignore its commitments under the agreement, or withdraw from it completely, if Trump were elected.
Asked about Trump's remarks on the Paris deal, China's top climate negotiator Xie Zhenhua said "a wise leader" should conform to global development trends.
"If you go against the tide, people will not agree and the economy and the social development of these countries will also be affected," Xie said earlier this month.
The Obama administration played a key role in making the Paris deal come together, particularly by forming a partnership with China that saw the world's top two polluters take the lead in global efforts to slash emissions of carbon dioxide and other greenhouse gases.
Under the Paris deal, the Obama administration pledged to reduce US greenhouse gas emissions by 26-28 per cent below 2005 levels by 2025.
But US Republicans are opposed to the deal, saying it will harm the US economy. Trump has called for stripping regulations to allow unfettered production of fossil fuels, a key source of carbon emissions, and rescinding the Clean Power Plan, an Obama administration strategy to fight climate change.
In Marrakech, delegates will be working on the details of implementing the Paris deal, such as drafting rules for how to measure and report emissions as well as the financial contributions meant to help poor countries deal with climate change.
The US under the Bush administration decided not to join the previous climate deal, the 1997 Kyoto Protocol, which only regulated the emissions of developed nations. That was a major blow to the agreement, and after other countries dropped out Kyoto ended up covering only a small portion of global emissions.
