Pittsburgh’s biggest challenge to meeting its climate change goals is to reduce the greenhouse gas emissions from its buildings. Buildings in the city produce four times as many emissions as vehicles. The city’s most substantial effort to do something about it was released last month: It made public the energy use of the city’s largest buildings. The hope is that transparency will encourage building owners to invest in energy efficiency and renewable energy.
To that end, we are publishing a map of where these emissions are coming from to help readers understand, across the city, neighborhood-by-neighborhood, which buildings emit how much.
The biggest source of greenhouse gases by building type are the hospitals and universities that drive the city’s economy. But collectively the city’s many office buildings emit more.
