Although the reality of climate change and its cascading effects are undisputed by many, some holdouts still disagree with the science, the human causation, or the ultimate severity of its impacts. But there is one place where we’re all about to find common ground on climate issues—our pocket books.

For some naysayers, the cost of cosseting our changing climate has been a block to believing. Taking the steps necessary to cut carbon emissions, invest in green jobs and infrastructure, or otherwise delay rising temperatures was simply too expensive. Now, there's an indication that we can’t afford not to.

That idea was driven home Wednesday, when a group of 285 investors beseeched governments to get their climate acts together before December's UN climate talks , according to an Associated Press report.

The multinational network of investors, which represents more than $20 trillion in assets, said keeping temperatures low was key to the global economy and that it would take legally enforceable carbon limits to stimulate the investment needed to do that, according to the AP article.

“Governments that act aggressively to enact strong, long-term climate and energy policy will reap the biggest rewards,” Mindy Lubbers, director of the U.S.-based Investor Network on Climate Risk told the AP. “They will drive the innovation, attract investment and create jobs.”

Along with the plea, the investors issued the Investment-Grade Climate Change Policy Report, which was created by the INCR’s parent group, the nonprofit Ceres. The report includes case studies and suggests incentives that would compensate clean energy investors for increased risk and the cost of establishing new technology, according to an INCR statement. The emphasis on long-term stability is key, the group said.

While the investment group represents large sums of money, the impact of inaction won’t be limited to the heavy hitters, UN Framework Convention on Climate Change Executive Secretary Christiana Figueres pointed out in the statement.

“This is the only way to guarantee the long-term sustainability and security of the world economic system, and the stability of returns from global investment,” she stated, “a major part of which is directly linked to the pensions and life insurance of ordinary people around the world.”
