While Philadelphia’s greenhouse gas (GHG) emissions per capita are less than half the national average, Greenworks nevertheless sets a goal to reduce emissions by 20% over 1990 levels by 2015. Many of the Greenworks targets and initiatives contribute toward reductions in GHG emissions, either directly or indirectly. To effectively monitor resulting emissions reductions, the Mayor’s Office of Sustainability is collaborating with the Philadelphia Department of Public Health’s Air Management Services, the City Planning Commission, and the Delaware Valley Regional Planning Commission (DVRPC) to form a greenhouse gas emissions working group.
In fall 2011, the working group will publish updated inventories for Philadelphia municipal government, all of Philadelphia County, and the nine county region served by DVRPC. In the process of developing these new inventories, the working group will establish a common baseline year of 2010 as well as a shared methodology for each inventory, an important step in making the process replicable and the data comparable. The team is coordinating the effort with PECO, PGW, and SEPTA to ensure data accuracy and availability.
In spring 2011, Philadelphia showed its leadership on GHG mitigation by participating in the first ever Carbon Disclosure Project for cities. Philadelphia joined cities across the world in disclosing GHG emissions data and climate change adaptation strategies as a first step toward developing global best practices.
