A first-order principal outcome must be that all nations are responsible for protecting the air and climate. Climate change may significantly accelerate the release of "old" Lindane-an agricultural insecticide used in Asia-from continental storage in soil, vegetation, and high mountains and initiate long-range transport from its terrestrial sources to deposition in the open oceans. Concern about automobiles as a source of air pollution has been expressed periodically, but concrete concern was first demonstrated in the 1960s, when California established the initial emission standards for new cars. The fundamental law regulating air pollution is the Clean Air Act of 1970, which authorized the development of comprehensive federal and state regulations to limit emissions from both stationary sources and mobile sources. The 1997, the Kyoto Protocol focused on strengthening the commitment to reducing greenhouse gases, creating three new mechanisms for the purpose, the best known of which is "emissions trading".
