Answer
Green chemistry is a way of thinking and is about utilising the existing knowledge and principles of chemistry and other sciences to reduce the adverse effect of pollution. For example:
Automobile engines have been fitted with catalytic converters which prevent the release of the vapours of hydrocarbons and oxides of nitrogen into acrolein and peroxyacetyl nitrate.
$\mathrm{CO}_2$ has replaced CFCs as blowing agents in the manufacture of polystyrene foam sheets.
