The Climate Institute is a nongovernmental organisation dedicated to informing key decision makers of climate change, and identifying practical ways to reduce emissions, in both the developed and developing world. It publishes and links to reliable background information on climate change, energy and the environment, and provides other resources such as maps, games and educational material.

The Stockholm Environment Institute is an international not-for-profit research organisation that aims to promote sustainable development through scientific analysis that supports decision-making on the national and international level. It focuses on four broad themes: reducing climate risks; managing land, water and air resources; improving governance; and developing new visions and pathways to development. The website provides free access to the institute's publications, describes current projects and links to useful modelling or policy tools such as LEAP (the Long-range Energy Alternatives Planning system) and IPAT-S.
