NEI Helps the Environment by Reducing its Carbon Footprint

Climate Registered LogoTo improve its environmental stewardship, Nuclear Energy Institute in 2008 joined The Climate Registry as a founding reporter, agreeing to voluntarily measure and publicly report its greenhouse gas (GHG) emissions each year.

Working with First Environment, a consulting firm that provides GHG emissions inventory support, NEI reports its carbon footprint—or total GHG emissions—annually and then takes actions to reduce that footprint. The GHG measurements are documented using The Climate Registry’s general reporting protocol and independently verified. Because all reporters use the same methodologies, representing best practice in voluntary corporate reporting of GHG emissions, the reported information is an accurate, consistent, high-quality data set of GHG emissions.

In reporting its carbon footprint, NEI strives to lead by example by fully assessing ways in which its employees and buildings can use less energy. For example, NEI's 2008 greenhouse gas emissions reported to The Climate Registry included emissions of 770 metric tons of CO2-equivalent. Since then, NEI reduced its greenhouse gas emissions by 30 percent, reporting 544 metric tons of CO2-equivalent emissions in 2012.

The 2012 report was verified by Complete Integrated Certification Services.

Since 2008, NEI has taken multiple steps to reduce its carbon footprint:

  • remodeled main office areas incorporating efficient lighting and insulation
  • built-out new Capitol Hill conference center to meet LEED certification standards
  • switched to energy-efficient light fixtures
  • reduced the number of hours air conditioning is used in the summer months
  • added subsidy benefits for employees to use public transportation and to telework
  • replaced old refrigerators and icemakers with newer, more efficient appliances.

In late 2012, NEI moved its office in Washington, D.C. The new office, designed and constructed to NEI's specifications, is energy efficient and holds a gold LEED certification. This new office has special features that moderate temperatures, reduce electricity consumption and save energy.

Other companies in the nuclear energy industry have also joined The Climate Registry, including Arizona Public Service Co., Duke Energy, Pacific Gas and Electric, SCANA and Xcel Energy. Nuclear energy provides the largest amount of carbon-free electricity in the United States, which helps the nation meet its growing electricity needs while reducing the effects of climate change.
