The world’s largest investors are using their assets – a combined $20 trillion – to push international policymakers to fight climate change. A coalition comprising 285 investors recently released a statement urging private-sector investment in climate change solutions that will create jobs and a more stable economic system worldwide.

The charge is being lead by three investor groups: the U.S.-based Investor Network on Climate Risk, Europe’s Institutional Investors Group on Climate Change and the Investors Group on Climate Change in Australia and New Zealand. Along with the statement, the group presented a report with case studies showing the climate polices of six of the world’s major emitters and examples of how investment policies can help governments craft future initiatives.

The statement and report was sent to the G20 and other governments in anticipation of the United Nations Framework Convention on Climate Change that is set to start in November. Investors are calling for changes at both the domestic and international level.

Domestically, the group is asking governments to create  long and short term objectives for greenhouse-gas emissions. They also want creation of financial incentives to reward low-carbon assets and the development of policies that accelerate the use of green buildings, clean vehicles and clean and renewable energy. Internationally, the group is asking for continued work on a binding international climate treaty, the development of a green climate fund and greater efforts to reduce emissions and deforestation.
