Several local companies have joined the city of San Diego and Cleantech San Diego to form a “2030 District,” pledging millions of square feet of commercial space to increase energy efficiency and reduce environmental impact.

A statement from Mayor Kevin Faulconer’s office said San Diego is the latest to join a network of 15 other similar districts across North America. The city’s goal is to have a 50 percent reduction in energy, water and transportation emissions in participating buildings by 2030.

San Diego’s program will be managed by the nonprofit Cleantech San Diego, as part of its Smart Cities San Diego initiative. Businesses joining the San Diego district effort include locally based sustainability product and service providers Verdani Partners and Measurabl, local offices of Intuit Inc. and DNV GL, and life-science property owner Alexandria Real Estate Equities Inc.

Also participating are the San Diego Regional Chamber of Commerce and the Urban Land Institute. San Diego’s Measurabl will provide software to underpin local 2030 District efforts to gauge energy use, and ULI’s Greenprint Center for Building Performance will provide industry best practices.

Officials said participation in the program is among efforts to carry out the city of San Diego’s climate action plan, passed in 2015, which calls for the city to cut half of all greenhouse gas emissions by 2035.
