What can we do to make sure that disasters like Deepwater spill don't happen again? Green chemistry, a science that calls for eliminating hazards and waste at the design stage rather than at the end of the pipe, is among the many answers to the question.

GE is expanding its successful Treasure Hunt program outside of its facilities in order to find energy efficiency opportunities in include hospitals, universities, city buildings and private sites through a new collaboration with the Environmental Defense Fund. The sites will learn how to conduct treasure hunts, while GE and EDF will work to verify the energy savings and identify and disseminate industry best practices.

Just as engine tune-ups help cars run more efficiently, retrocommissioning helps property owners tune up the energy efficiency of their buildings so they perform as designed -- or better. The process is considered the most cost-effective strategy for reducing energy consumption and greenhouse gas emissions.

CFOs, CIOs and sustainability teams at large companies have used spreadsheets for years to track corporate carbon emissions.  We are now, however, at a tipping point where the benefits of carbon management software outweigh the benefits of spreadsheets.

What is the best way to drive energy efficiency without sacrificing functionality or aesthetics? These three rules can help navigate this dilemma and formulate structured plans to get the most out of efficiency projects.

United Parcel Service decreased energy and water use as well as its greenhouse gas emissions last year in the U.S., prompting the company to set a new goal of 20 percent improvement in automotive fuel efficiency by 2020, according to the firm's latest sustainability report.

Although technology has already done wonders in making the world more efficient, IT still claims an outsized share of the world's energy and emissions. We need to focus on growing IT's reach without growing its impacts.

The guidance is an important first step towards standardized reporting of climate issues for the benefit of investors, but will likely spur more corporate scrutiny and disclosure of climate and water risks in overseas supply chains.

The U.S. government is funneling more than $100 million to six projects that will turn carbon dioxide (CO2) into fuel, plastics, cement and other products.

The inordinately complex processes of developing a truly connected grid means that progress is happening slowly even as the technologies behind it are coming up to speed. These 10 lessons highlight the potential and challenges we face on the path to a smart grid.

What do you do when it seems that nearly all the low-hanging fruit of energy savings has been harvested? You stretch and look for more. That's what the EDF Climate Corps fellow at eBay has done this summer in her assignment at one of the greener companies in Silicon Valley.

Green roofs, green buildings and an energy management system have put the United States Postal Service on the fast track to achieve its 2015 energy reduction goal and have helped the agency reap $400 million in savings in the past three years.

Looking for new opportunities for energy efficiency at a deeply green company is like trying to find a gift for a person who seems to have everything. For the EDF Climate Corps fellow at Yahoo! it means expanding his search for energy savings across the company's global operations.

Audit, tax and consultant firm KPMG has exceeded its carbon footprint reduction goal a year ahead of schedule.

The devastating flooding in Tennessee last spring  wreaked havoc on the energy infrastructure of Opryland, Gaylord Entertainment's flagship resort and convention center. The neccessity of replacing these systems, however, provided a strong business case for exploring more efficient systems, such as combined heat and power.

It's been a huge success. It hasn't gone anywhere. Actually, it's a little of both -- depending on which state you look at.
