How Construction Harms the

       Environment






       There are many societal impacts of construction. Methods,
       materials, and operations all contribute to the                              Shifting Attitudes and
       environmental impact of construction.  Construction                          Societal Change

       to 40 percent of the world’s total carbon emissions.                         Sustainability through
       Estimates suggest that emissions from commercial buildings
       can grow up to 1.8 percent in 2030. Mining projects extract                  Green Construction
