The article, written by scientists at the International Institute for Applied Systems Analysis (IIASA), Austria, finds that policies focusing on mitigating climate change have synergistic effects in other dimensions, as they necessarily involve massive improvements in energy efficiency and the rapid and widespread deployment of clean, secure energy sources, in particular renewables.
"A clear advantage of pursuing ambitious climate policies is that, in general, many of the technologies and clean fuels that they will motivate, will simultaneously reduce both carbon emissions and a suite of other air pollutants that are harmful to the health of humans and the environment," says lead author David McCollum of IIASA.
"Moreover, once stringent climate policies are in place, our calculations show some strong synergies. The additional costs of supplementary policies to achieve the air pollution and energy objectives are significantly reduced -- by several hundred billion dollars per year globally, or approximately one-half of one per cent of global GDP."...
