De mate waarin een stof bijdraagt aan het versterkt broeikaseffect wordt uitgedrukt in de GWP (global warming potential). De GWP van een stof is gedefinieerd als het opwarmingsvermogen van$1{,}0 \mathrm{~kg}van de stof in vergelijking met1{,}0\mathrm{~kg}\;\mathrm{CO}21{,}0\mathrm{~kg}\mathrm{CO}21{,}0\mathrm{~kg}\mathrm{CO}2$1{,}0 \mathrm{~kg} \mathrm{CO} 2, berekend over een periode van 100 jaar.
Om te berekenen welke winst er wordt gehaald met het oog op het broeikaseffect, gaat men uit van een situatie waarbij alle gas uit de schakelaar ontsnapt. Hierbij wordt de bijdrage aan het broeikaseffect omgerekend naar overeenkomende massa$\mathrm{CO}_{2}-uitstoot.
