IBM, Procter & Gamble, Lockheed Martin, Clif Bar, Bank of America and Gap are among the companies to receive EPA awards for reducing greenhouse gas emissions and taking action to mitigate the effects of climate change.

The agency today announced the 2017 Climate Leadership Award winners, including five organizational leadership awards that went to:

DFW Airport, the only airport to be recognized two consecutive years by the EPA in the Climate Leadership Awards program’s six-year history, received the award for its Sustainability Management Plan, which prioritizes energy efficiency and greenhouse gas emissions reduction. The airport included GHG emissions per passenger as a key performance indicator in its FY2016-2020 Strategic Plan, with a goal to reduce the kilogram per passenger of carbon from 2.88 to 2.45 between 2015 and 2020. This represents a 15 percent total reduction, or 3 percent annual reduction.

The airport also uses low- and no-carbon vehicles in its fleet, including compressed natural gas in its bus fleet operations, with multiple fueling stations for airport fleets and the surrounding community. DFW also uses hybrid-electric fleet vehicles and has provided electrical charging infrastructure to support ground support equipment operations and passenger vehicles.

Last summer, DFW Airport became the first carbon neutral airport in North America by switching to renewable energy sources and converting its bus fleet to compressed natural gas vehicles, among other low-carbon initiatives.

Global investment firm Goldman Sach’s organizational leadership accomplishments include achieving carbon neutrality across operations and business travel in 2015, the EPA says. The company has also committed to a 10 percent reduction in absolute energy use from 2013 to 2020 and use of 100 percent renewable energy.

IBM, which has received EPA Climate Leadership awards every year since 2012, has set a goal to reduce absolute GHG emissions by 35 percent by 2020 against a 2005 baseline, adjusted for acquisitions and divestitures. IBM says it will achieve this goal through increased energy efficiency across operations and through renewable energy procurement (20 percent of its annual electricity use by 2020).

In 2015, IBM contracted 17.5 percent of its global energy purchases through green power, above and beyond renewable electricity IBM receives automatically via grid purchases.

Additionally, the company developed a global environmental management system (EMS), which serves as the foundation for its efforts to address climate change and inform business strategy. It also requires all IBM suppliers to have an EMS, inventory their energy use and GHG emissions, establish reduction plans and publicly report their results.

Lockheed Martin received an organizational leadership award in part for its absolute GHG reduction goal of 35 percent from 2010 through 2020 for global operations.

The company optimizes energy use through its Go Green 2020 program, which includes energy efficiency and renewable energy projects, with a pledge to quadruple on-site renewable generation to 10 MW by the end of 2020. The company achieved 18 percent energy and 23 percent GHG reductions from 2010 to 2015 towards its Go Green goals. In 2015, Lockheed initiated or completed more than 40 energy efficiency and GHG reduction projects.

One of the company’s goals is to achieve $4 billion in product sales with direct, measurable benefits to energy and advanced infrastructure resiliency by 2020. It has also committed to help customers reduce their GHG emissions by at least twice the GHG impact of business operations by 2020.

Procter & Gamble has set several 2020 goals including: an absolute GHG reduction of 30 percent for global operations using 2010 as a baseline, using 30 percent renewable energy, and a 20 percent reduction in truck transportation which was exceeded last year when it reached a 25 percent reduction.

The company has also set a goal to double its use of recycled resin in plastic packaging by 2020. To date it has increased it by 30 percent and also achieved its goal to have 100 percent of the virgin wood fiber used in tissue/towel and absorbent hygiene products be third-party certified.

Previously P&G said its environmental management efforts have saved almost $2 billion through waste and energy costs since 2007.
