Amid the controversy around the just released EPA Clean Power Plan rule, the impacts of climate change are becoming apparent with a proliferation of heat waves, droughts, floods, wildfires and other extreme weather events and trends, both in the U.S. and globally. While many climate scientists (and world governments in the 2010 Cancun Agreements) have agreed that it is necessary to limit average global temperature rise to 2 degrees Celsius to avoid potentially catastrophic and irreversible effects of climate change, the impacts we’re now witnessing result from a temperature rise of just under 1 degree C. We are currently on a trajectory toward a 3 to 4 degree (or more) increase, which has sobering implications.
In preparation for the COP 21 negotiations in Paris, world governments are engaged in a “bottom up” process of submitting proposed national emission reduction pledges poetically called Intended Nationally Determined Contributions (INDCs). These are not expected to get us to a 2 degree future, but will hopefully form the basis for an international agreement that sets the world on a path toward that target or something close.
The U.S. INDC calls for reducing our emissions by 26-28 percent below 2005 levels by 2025, which will require additional measures beyond those currently proposed or in place (including the EPA Clean Power Plan, CAFÉ and truck efficiency standards, methane and HFC controls). All of these measures are controversial and under attack from various quarters. As the world’s second largest emitter, the U.S. must implement credible and effective emission reduction strategies to convince other major emitters in the developing world (China, India, et al) to control their emissions and to help avoid the worst effects of climate change.
Solving climate change clearly poses huge challenges, but it also presents huge economic opportunities. As highlighted in Ceres’ 2014 Clean Trillion report, International Energy Agency analyses show that the world needs an average of more than $1 trillion in additional annual investment in clean energy technologies (renewable energy, energy efficiency, efficient transport, etc.) beyond 2012 levels of about $250 billion. This creates a massive need for capital, and presents a huge economic and investment opportunity to finance the necessary low carbon, clean energy economy.
A global transition to a low carbon economy is in progress and accelerating, but too slowly. Policies that put a meaningful price on carbon emissions and eliminate fossil fuel subsidies are needed to scale up clean energy investment. Fortunately there is growing business and investor support for such actions, as evidenced by the Global Investor Statement on Climate Change and recent letters from more than 350 companies supporting EPA’s Clean Power Plan. More such voices are needed to make the business and political case for solving climate change, before it is too late.
