Atmospheric goals for sustainable development.

Atmospheric chemistry and composition underlie the existential threats of climate change and ozone depletion (1), and poor air quality represents the greatest environmental health issue in the modern world (2). However, the only targets and indicators related to atmospheric health and clean air in the United Nations Sustainable Development Goals (SDGs) focus on reducing fine particulate pollution levels and the associated mortality rates (3, 4). By creating targets for a broad range of specific pollutants, the SDGs could facilitate more effective actions, monitoring, and funding.
