Reducing use of fossil fuels would considerably reduce the amount of carbon dioxide produced, as well as reducing the levels of the pollutants which cause acid rain. This can be Archieved by either using less energy altogether, or using alternative energy sources.

Eliminating the use of CFCs is something we can actually do. New refrigerants have been developed, and new aerosols use other propellants such as butane, so it is now actually quite difficult to get hold of CFCs.

Stopping deforestation by using renewable forests and planting a new tree whenever one is felled would help to raise the carbon dioxide absorbing ability of the planet.
