A tool to combat air pollution and climate change simultaneously

Current and future economic growth will cause serious air quality problems in Asia, negatively impacting human health and crop production, unless further air pollution control policies are implemented. Increased economic activity will also lead to more greenhouse gas emissions and subsequent climate change. Yet, air pollutants and greenhouse gases can be reduced simultaneously at far lower costs because they often originate from the same sources.

An international team of researchers have developed a scientific tool to guide policy makers through the complex process of air pollutant controls and greenhouse gas mitigation in China and India. Known as GAINS (Greenhouse Gas and Air Pollution Interactions and Synergies), this state-of-the-art interdisciplinary model builds on a scientific tool that has already helped European governments slash air pollution across the continent without compromising economic development.

Current versions of the GAINS online model for two regions of Asia are available here:
