Today our emissions are lower thanks to a combination of renewable energy, energy efficiency and plant improvement projects. Since 2005, we have reduced by half emissions of nitrogen oxides and sulfur dioxide from the generating plants we own. We also are on track to surpass our goal to reduce carbon dioxide emissions by 20 percent by 2020 from 2005 levels, with current projections indicating a 27 percent reduction. Our clean energy strategy allows us to focus on those initiatives that produce the greatest benefits at the best price and positions us to meet future environmental regulations. Through this approach, we are meeting the many diverse—if not competing—interests of the people we serve by offering customers choice, keeping energy prices competitive, modernizing our infrastructure, investing in local economies and improving the environment.
We published our first corporate responsibility report (formerly known as the Triple Bottom Line report) in April 2005, with the contents covering the 2004 calendar year, and we have published a similar report in each following year. Our report is based on Global Reporting Initiative (GRI) G3 Sustainability Reporting Guidelines, the most widely used sustainability reporting framework in the world. Additionally, we incorporate the GRI’s Electric Utilities Sector Supplement indicators wherever possible.
