99 percent of the world’s population is breathing air that’s harmful to their health. Over the last 5 to 10 years, there's been a huge increase in the amount of evidence about the health impacts of pollution. Now, we are presented with a massive opportunity to improve public health and combat climate change at the same time. But how? And what is the role of the transportation sector in this crucial discussion? Just in time for COP27, we bring together Eva Scherer, Siemens Head of Investor Relations, and Jane Burston, Clean Air Fund Executive Director, to explore why cleaning up our air is so vital and how companies and every single one of us can contribute. We also look at the role that the Alliance for Clean Air, of which Siemens is a founding partner, is already playing in the fight to cut air pollution and why data is so important.
