Why do you work for the Clean Air Fund?
With its direct links to climate change and its wide-ranging impact on everything from health to inequality, air pollution is one of the most pressing issues of our time. I’m proud to be providing operational support to such an important and ambitious mission, alongside a hugely passionate and committed team.
