In 100 short days, the world has transformed. Since the reelection of President Donald Trump, US federal climate policy has largely been abandoned, with the government seeking to reopen coal-fired power plants and lower environmental standards. 

An escalating trade war and global tariffs has sent the rest of the world reeling and threatened the global financial system with collapse. China has come under particular fire, but the US has also targeted its closest allies and neighbours — Canada, Mexico and the EU — with tariffs. 

Any sense of certainty has been thrown out of the window as a more inward looking US seeks to reshape the global order. So what does all this mean for the energy transition, and plans to reach net-zero? Michael Liebreich and Baroness Bryony Worthington join forces for the opening episode of Season 15 of Cleaning Up to discuss.
