Carefully choosing how we reduce greenhouse gas emissions will have the added benefit of reducing global health inequities. Climate change due to emission of greenhouse gases from fossil fuel energy sources causes air pollution by increasing ground-level ozone and concentrations of fine particulate matter. —Kirk R.
Cars That Think
