Arlington Greens Release Lecture on U.S. LEED Green Buildings by Oberlin college professor Scofield, Finding Minimal Environmental Benefit

The Arlington Greens announced today the release online of a talk on March 2 in Arlington by Oberlin College of Ohio professor John Scofield, a national expert on green building technology, on his research into marketing claims that green-certified buildings such as the LEED rating significantly reduce carbon emissions.  EcoAction Arlington, an Arlington environmental non-profit organization, co-sponsored the talk held at the Arlington County public library with the Arlington Greens.  The Arlington Independent Media and Miriam Gennari of the Sustainable Scoop recorded the talk and interviewed professor Scofield.

Professor Scofield used energy data from hundreds of thousands of commercial buildings in ten major U.S. metro areas to examine if energy certifications like LEED (a trademark meaning “Leadership in Energy and Environmental Design”) significantly reduce carbon emissions over non-certified comparable buildings.  His findings demonstrate very small, almost negligible carbon savings.  Scofield found that carbon emissions reductions in LEED buildings are quite modest, generally well below 10 percent, and well below marketing claims of over 25 percent.

The research finding that LEED and other similar commercial building energy rating systems save only negligible amounts of carbon emissions is an important environmental policy issue for Arlington County and for many other U.S. communities.  Over 40 such certified buildings in the county got generous subsidies based on now discredited claims of substantial carbon emissions reductions.  Arlington County subsidies for bogus green energy technology wastes county funds which should be used to incentivize proven effective green technology that does substantially reduce carbon.

In 2019, the Arlington County Board approved a community energy goal that the county become carbon neutral within 25 years.  About 80 percent of carbon emissions in the county occur in commercial and residential buildings, and thus the county’s goal can only be achieved by large carbon emissions drops in buildings.   The county government’s past reliance on LEED and similar energy certifications to reduce energy use in commercial buildings now appears to be wrong.
