b'ENVIRONMENT ENVIRONMENTInnovative Natural Gas Technologies Provide Clean and Combined Heat and Power Delivers Low-Carbon, Affordable Efficient Energy Energy SolutionsWe partner with customers and suppliers to apply innovative technologies that deliver sustainable solutions for a cleanCombined heat and power (CHP) is an efficient and clean approach to generating electric power and usefulenergy future, providing yet another pathway to protect and preserve our environment today and for generations to come. thermal energy from a single fuel source, typically natural gas. The heat created from producing electricity, whichis typically wasted, is captured and turned into steam or hot water that can be used for space heating, cooling,domestic hot water, and industrial processes. A 2016 Department of Energy study cited CHP as a clean energy solution that has a number of benefits, including reducing greenhouse gas emissions and energy operating costs,Valued Partnerships Deliver Renewable Energy in addition to increasing energy efficiency up to 75 percent when compared to electricity from the grid.The transportation of landfill gas is an important element of our strategy to5.1 Bcf CHP is utilized in a variety of industrial facilities and commercial buildings to simultaneously supply electricity and responsibly reduce methane emissions. According to the EPA, municipal solid wasteOf renewable natural provide thermal loads. CHP can also be integrated into district energy systems utilized by colleges, hospitals,(MSW) landfills are the third-largest source of human-related methane emissions ingas transported downtown areas, and other campus-type facilities. A district energy system is a centralized facility that generatesthe United States, and methane has a global warming potential more than 25 timessteam and hot and cold water that is piped through an underground network to buildings for space heating, airgreater than CO 2 . Reducing methane emissions can achieve significant near-term58,000 conditioning, and other energy needs.benefits in mitigating global climate change, so MSW facilities represent a unique opportunity to capture, convert, and use landfill gas as a renewable energyEquates to removing almostresource.

Our relationship with River Birch landfill demonstrates how we are helping companies transport their RNG to market.
