Similarly, the US has different environmental standards than the EU and the UK will have to choose the regulatory system it wants to align with. The non-regression of environmental standards and «Level Playing Field» rules are part of the Withdrawal Agreement, both of which aim to ensure a baseline of current standards after Brexit (if a deal is reached). However, these concern only a limited area and are legally difficult to challenge. There are still ways to affect the environment through a trade agreement with the United States. For example, many products made in the US with less environmentally friendly practices could be sold in the UK, even if these practices are banned in Britain. A trade deal could also lead to US direct investment, which could put pressure on UK municipalities to admit polluting activities such as fracking. Within the EU, general principles (such as the precautionary principle or the polluter pays principle) guide legislation. The United Kingdom and the United States do not have the same legal structure that enshrines these principles. It is therefore unclear whether environmental standards will remain the same after Brexit or whether a US trade deal will lead to deregulation pressures.
Britain had embarked on a trade deal with the administration of Donald Trump, a staunch opponent of the European Union, but Biden said in an interview with the New York Times that his priorities will be to improve investment in American production and the protection of American workers. Another factor is that the US will likely use a DEAL between Britain and the US as leverage for a more advantageous deal between the US and the EU, meaning that the US will likely achieve its goals vehemently. U.S. trade policy is currently not reluctant on this front, as the publication of the U.S. government`s negotiating objectives for a trade deal between Britain and the United States has shown. In 2017, the U.S. trade agenda for 2017 called for a «more aggressive approach» to trade and the use of «all possible levers to encourage other countries to allow U.S. producers fair and mutual access to their markets.» A MUTUAL RECOGNITION AGREEMENT (MRA) is an agreement in which countries recognise each other`s conformity assessment results. . . .
