Our Low-Carbon Pathway

DRIVING A CLEAN ENERGY FUTURE ONE OUR NATION'S ENERGY FUTURE THANE U.S. CHALLENGE EPA MJB & A Natural Gas an ERM Group company Supply Collaborative . The ONE Future coalition represents more than 15% of the U.S. natural gas value chain committed to reducing methane emissions through adopting science- based standards and deploying best practices. Target of reducing emissions across the natural gas value chain to 1% (or less). One Future reports 2020 methane intensity of 0.3%, beating its 1% goal by 67%, and demonstrating the industry can deliver one molecule of gas from the rig to the burner tip with 99.7% efficiency. As a Methane Challenge founding member, NW Natural is adopting advanced practices in an effort to further reduce methane emissions, such as alternative blowdown methods in pipeline construction and maintenance. The traditional approach to depressurizing a pipeline is to vent the gas to the atmosphere. But by flaring it with a mobile flaring unit we can reduce potential greenhouse gas emissions by up to 90%. In 2020 these voluntary practices helped avoid releasing the estimated equivalent of nearly 3,000 metric tons of carbon dioxide, reducing emissions by more than 60% on these projects. < gti. neea LCRI LOW-CARBON RESOURCES INITIATIVE North American Gas Heat Pump Collaborative TECHNOLOGY FOR A CLEANER FUTURE • • The Northwest Energy Efficiency Alliance (NEEA) is an alliance of utilities and energy efficiency organizations that pools resources and shares risks with a mission to transform the market for energy efficiency to the benefit of consumers in the Northwest. Gas Technology Institute and the Low-Carbon Resources Initiative are non-profits that encourage innovation through new products like gas heat pumps, zero- net energy homes, fuel cells and other progressive technologies that strive to use less energy. NW Natural is a founding member of the North America Gas Heat Pump Collaborative, which is made up of gas and dual fuel utilities and energy efficiency program administrators who believe gas heat pump technologies play an important role in decarbonization. RENEWABLE NATURAL GAS K AMERICAN BIOGAS COUNCIL Coalition for Renewable Natural Gas, a member-led nonprofit organization representing nearly 300 companies, municipalities, universities, and environmental and nonprofit organizations that are dedicated to the advancement of RNG. The coalition advocates for public policy that supports sustainable development and use of renewable natural gas, so present and future generations will have access to renewable fuel. In like manner the American Biogas Council is championing the growth of the biogas industry. 25 HYREADY RHA RENEWABLE HYDROGEN ALLIANCE • Hyready is a worldwide collaboration on hydrogen, which is focused on creating guidelines and best practices for natural gas distribution companies blending hydrogen into their distribution systems. The Renewable Hydrogen Alliance is a non-profit established to promote and advocate using renewable electricity to produce hydrogen and climate neutral derivative fuels.
