Five years of carbon footprint reporting yields impressive results

The Port of Portland just marked its fifth year reporting to The Climate Registry. The Port became a founding greenhouse gas emissions reporter of TCR in 2008, primarily in response to an ambitious goal set by the Port’s Commission to reduce the Port’s GHG emissions by 15 percent below 1990 levels by 2020. 

The Port uses TCR’s robust voluntary GHG reporting program to measure, publicly report and provide third-party verification for the Port’s carbon footprint. TCR is a non-profit organization established to develop a common, accurate and transparent GHG reporting standard in North America. TCR uses internationally recognized GHG measurement standards developed by the World Resources Institute, the Intergovernmental Panel on Climate Change, and the World Business Council on Sustainability.

Based on the initial emissions inventory, the Port adopted a combined approach focusing on energy conservation strategies, replacing and retrofitting older equipment and purchasing renewable power. The Port consistently earns high rankings nationally on the U.S. EPA’s Green Power Partner list. The Port now purchases 100 percent renewable power and is currently ranked 25th among 100 percent renewable purchasers and 9th among local government purchasers, with over 75 million kilowatt hours of renewable power certificates.

The inventory has also served as the foundation for the Port’s carbon footprint reduction and energy management strategy which prioritizes projects to increase energy efficiency. Building awareness around the Port’s carbon footprint has delivered real results. Based on data from the 2012 reporting year, the Port had reduced its GHG emissions by an incredible 60 percent below 1990 levels – four times the original goal!
