The world is in the grip of a climate emergency. Urgent and equitable action is essential to prevent yet further escalating climate impacts that are devastating communities worldwide and to safeguard a liveable planet for future generations. For governments everywhere, including the UK Government, this is a defining test of leadership. But it is also a moment of opportunity—an opportunity to build economies and societies that are not only decarbonised and climate resilient, but that actively reduce inequalities, are more inclusive, and prioritise the wellbeing of people and the planet over short-term profit. In this report, we outline key steps the UK Government can take to lead the way toward a just and transformative transition—one that not only stabilises the climate but also delivers fairness and justice for all.
