For example, the creation of a welfare state and the NHS after World War II brought about radical and previously unimaginable changes that remain crucial to our lives generations later. Now, we have a similar historic opportunity for change: the chance to develop a long-term strategy to address the climate challenge by balancing climate action with the environment and the economy to benefit everyone in society. I have said many times that, from every sector to every person, we each have a role to play. If anyone believes that we can address the climate emergency, improve the natural environment and advance the circular economy without huge effort, they are seriously mistaken.
