How much is spent each year to reduce air pollution?

Answer 1

The global spending on air pollution reduction varies widely by country and region, but estimates suggest that billions of dollars are invested annually. For instance, in the United States, funding for air quality initiatives, including regulatory enforcement and clean air programs, can exceed $10 billion each year. Many countries also allocate significant budgets for renewable energy projects, public transportation improvements, and emissions controls, all aimed at mitigating air pollution. Overall, while precise figures can fluctuate, the investment in air pollution reduction is considerable and essential for public health and environmental sustainability.
