LEED may be an international certification, but recently the USGBC has phased in credits for green building practices tackling region-specific environmental problems. The new "regional priority credits" were introduced in 2009, as part of an overhaul of the LEED ratings [source:U.S. Green Building Council]. You can get up to four bonus certification points for upgrades to your home that help solve local environmental problems [source:U.S. Green Building Council]. For example, if you live in a rural area, you might be able to get bonus points for landscaping that prevents erosion into irrigation water for nearby farmland. If you live in a sunnier clime, such as the southeastern United States, installing solar panels might net you some bonus points. There are special credits for each of the 50 states, as well as Puerto Rico and international projects, too.
