The USA Biden administration restored a legal foundation for regulating and governing mercury, which could pave the way for even stricter controls on mercury emissions from power plants. The restored governance includes again a method of calculating emissions that will allow consideration of collateral benefits. This is focused on the public health benefits of limiting mercury such as prevention of disease and premature deaths, using science-based evidence for the health and well-being of all people.
While this is a story from the US, perhaps an opportunity for sharing information on calculating emissions, and regardless it signals a shift that can be important in international convenings for global governance on mercury from multiple sources to support ISLANDS countries and mercury-related initiatives.
