(C) There are five gases of human origin that contribute most – together up to 95% of the total – to the increase in global warming. (D) Following methane, halogenated compounds such as CFCs, HCFCs, HFCs, PFCs, SF6 and NF3 are responsible for 11 % of global warming and generated as a result of the production of chemicals by diverse sectors.
