Some industrial gases have very high Global Warming Potentials (GWP). A high GWP means that an equal mass of gas causes much more global warming than CO 2 over a period of time, typically 100 years. The destruction of these gases before they are emitted is therefore a very effective way to reduce GHG emissions.
