Christy Clark is the premier of British Columbia, which has had a revenue-neutral carbon tax since 2008. She spoke ahead of the UN Secretary-General's Climate Leadership Summit about the impact of carbon pricing on the economy.
Henri Proglio is the chairman and CEO of Électricité de France (EDF). He spoke ahead of the UN Secretary-General's Climate Leadership Summit about the importance of carbon pricing for the electricity sector to move toward a low-carbon economy.
Anthony Earley is the chairman and CEO of PG&E Corporation, the parent company of Pacific Gas and Electric. He spoke ahead of the UN Secretary-General's Climate Leadership Summit about the importance of California's climate policies and carbon pricing in encouraging a shift to clean energy solutions.
According to the International Energy Agency (IEA), global energy demand is likely to grow by more than one-third between now and 2035. Mobilizing investment capital is one major task. Additionally, energy infrastructure such as electric power facilities has a long time span – up to 40 or 50 years in the case of base-load nuclear or coal plants. As the new Growing Green report, released by the World Bank’s Europe and Central Asia Region, points out, with such a long time span and the enormous amount of capital at stake, power sector investments need to consider at least three types of uncertainties—changing regulations, changing technology, and changing climatic conditions.
Regulatory uncertainty persists in countries without formal greenhouse gas emission restrictions. Even in the EU, the emissions trading system is still evolving and future prices for carbon emissions will in large part depend on political decisions. Such schemes may spread to other parts of Europe and Central Asia as the implications of climate change become more apparent and support for climate action rises. A price on carbon, either through a cap-and-trade sys¬tem or a tax, can profoundly alter the comparative economics of different power generation technologies. With a price on carbon emissions, the cost differential between fossil-fuel plants and low-carbon alternatives shrinks and in some cases disappears.
Many international firms and banks already incorporate an assumed carbon price into their financial investment feasibility calculations. Expectations of future carbon pricing have already altered investment decisions favoring natural gas over coal-fired power plants in the U.S. (although more recently the drop in gas prices has been a larger factor). Conversely, regulatory uncertainty also hinders investments in low-carbon generation. The IEA estimates (pdf) that uncertainty in climate change policy might add a risk premium of up to 40 percent to such investments, driving up consumer prices by 10 percent.
