We are an independent research organisation focused on revealing the trends, causes, and health impacts, as well as the solutions to air pollution. Health-harming pollutants from burning fossil fuels are responsible for at least 3 million air pollution deaths per year. However, rapid advances in modern, clean energy technologies are a key opportunity to improve air quality and protect public health. We use scientific data, research and evidence to support the efforts of governments, companies and campaigning organizations worldwide in their efforts to move towards clean energy and clean air. We believe that effective research and communication are the key to successful policies, investment decisions and advocacy efforts.
