As cities expand and multiply, their citizens and infrastructure are greatly affected by the environmental risks and associated costs of climate change. For this reason, many cities and some states are requiring that the energy performance and/or carbon emissions of buildings be disclosed. These mandatory disclosure programs have been so successful in reducing carbon emissions that a growing number of states, counties and cities are now adopting them.
How mandatory disclosure programs operate
Typically, these programs require annual disclosure for commercial and sometimes multi-residential buildings over a certain size. In New York City, for example, the policy applies to buildings over 50,000 square feet. These buildings constitute only 2 percent of New York City’s buildings, but account for 50 percent of the total floor area of commercial buildings. The relatively small number of buildings makes the program manageable, while the large floor area that they represent can make a significant impact. Many U.S. cities have set ambitious goals. Portland, Ore. set a goal of cutting carbon emissions by 80 percent by 2050. Atlanta projects that its ordinance will drive a 20-percent reduction in energy consumption by 2030.… Read More
