There are a few things that I would give as examples. One thing that we did in about 2010—and it continues—is to issue a better buildings challenge at the community level to encourage people who have commercial buildings to reduce their energy use by 20% in 10 years. They are able to leverage the expertise of the U.S. Department of Energy to assist these communities, so it would be not just private buildings but also public sector buildings—so any U.S. government buildings and those owned by state and local governments.
The other thing that was incorporated into some of these executive orders was to work at the regional level. In some cities.... For example, in San Francisco, a number of federal agencies have regional offices, so they were encouraged to not only work together with the other federal agencies that have large presences in San Francisco, but also work with the community on greening programs and to participate in these regional greening programs.
