Climate change and energy security are big, global issues that can leave the average individual feeling powerless to make a difference. Top Ten lists describing ways to reduce your environmental footprint and lead a healthier, more sustainable life can seem trivial in light of the scale of the challenge. But the truth is that solutions to society's greatest challenges can be the cumulative effect of lots of relatively small, individual actions.

One often overlooked opportunity that could represent nearly 40 percent of the solution to fight climate change is the built environment. According to the U.S. Department of Energy, buildings' energy use accounts for 39 percent of the United States' carbon emissions. Building designs often fail to make the most efficient use of water, an increasingly scarce and valuable resource. The materials used to build them are often harvested and transported in ways that are detrimental to the environment.

The opportunity to make real change by building and renovating greener buildings is tremendous. Businesses, governmental agencies, school districts, homeowners — anyone who plays a role in planning, designing, building, operating or maintaining buildings — can save money, live and work in greater comfort and health, enjoy the durability of longer-lasting buildings, and help in the fight against environmental degradation all at once.

LEED certification
Green building is fast becoming the norm in the building industry, with the U.S. Green Building Council (USGBC) leading the way. Established in 1993, USGBC is growing at a dramatic pace. USGBC now has more than 16,000 member organizations. They include building owners and end-users, real estate developers, facility managers, architects, designers, engineers, general contractors, subcontractors, product and building system manufacturers, government agencies and nonprofits.

But with the tremendous growth of green building comes the risk of "greenwashing" — products, services and building methods being sold as "green" for marketing purposes without actually contributing to a more sustainable built environment. That's why in 2000 USGBC launched the LEED Green Building Certification System. LEED is a technically rigorous, third-party certification system for buildings, developed by consensus among USGBC's membership and drawing from public comment. It was created to assure building owners and occupants their green buildings really were built to perform as they are supposed to.
