 Clean air is air that you cannot see any pollution, cannot smell any pollution, and most importantly, it's air that does not have any negative impact on your health or well-being. Air pollution has a devastating impact on people's health around the world. The latest figures indicate that more than 7 million people are dying prematurely each year, which includes over 600,000 children under the age of 5, and 90% of people in the world are breathing air that fails to meet World Health Organization guidelines. The right to a clean and healthy environment is one of the most fundamental human rights that exists. It's about clean air, clean water, adequate sanitation, healthy and sustainably produced food, a non-toxic environment, healthy biodiversity, and a safe climate. To ensure clean air and the right to a healthy environment, states need to do 7 things. First, they need to monitor air quality, then they need to assess the sources of air pollution. Third, engage the public. Fourth, establish laws, regulations and standards. Fifth, have a national plan, an action plan to achieve those standards. Sixth, they need to have adequate resources to achieve their objectives. And seventh, they need to ensure that they're tracking progress and strengthen their plan if they need to. In the world, I would say Costa Rica and Norway are really at the top of the rankings. Costa Rica has a terrific record. They recognize the right to a healthy environment in their constitution. They've protected over one quarter of their land in national parks. 99% of their electricity comes from renewable energy. And similarly in Norway, they also amended their constitution to recognize the right to a healthy environment. And Norway has done a terrific job in many environmental areas. For example, leading the world in electric vehicles and also generating almost all of their electricity from clean, green renewable energy. In another region, I would say probably it's more challenging, but the Philippines has done some really interesting things and the Philippines is one of the few countries in the world that actually has a law called the Clean Air Act where they recognize their citizens have a right to breathe clean air.
