Washington Gas Earns Top Utility Environmental Champion Ranking in U.S. Survey

WASHINGTON–(BUSINESS WIRE)–Washington Gas Light Company, a WGL Holdings, Inc. (NYSE: WGL) company,
has been named a Top Utility Environmental Champion of 2018, according
to a new Cogent Reports survey of utility customers nationwide conducted
by Market Strategies International. The results designate the top 43
utilities throughout the country that have shown dedication to
environmental stewardship and are published in a report called Utility
Trusted Brand & Customer Engagement™: Residential.

Washington Gas was recognized based on a study of 62,565 customers,
served by 131 of the largest residential gas and electric utility
providers, who were asked to rate their utility company’s commitment to
the environment. The survey scored an Environmental Dedication Index
compiled from consumer ratings of five critical environmental
attributes, including being committed to using environmentally friendly
energy sources, providing tools and programs to help customers conserve
energy, supporting environmental causes, encouraging green initiatives
for buildings and vehicles, and seeking ways to protect the environment.

“We are excited to earn recognition that is based on direct customer
input as one of the top utilities in the industry for our firm
commitment to environmental stewardship as a core corporate value,” said
Adrian Chapman, President and Chief Operating Officer, Washington Gas.
“Our continued dedication to protecting the environment is reflected in
our own sustainable business practices as well as our ongoing
initiatives to help our natural gas customers to reduce carbon
emissions, adopt energy efficiency strategies and support a clean energy
future.”

Several Washington Gas programs and business practices contributed to
this recognition, including:

• Washington Gas operates more than 220 natural gas vehicles in its
  fleet and maintains LEED® (Leadership in Energy and Environmental
  Design)-certified buildings such as its operations center in
  Springfield, Va., and Northwest
  Station fleet facility in Rockville, Md.
• By 2025, Washington Gas has committed
  to operating completely carbon neutral facilities and fleet across all
  the WGL companies, to achieving a 38 percent reduction in carbon
  emission intensity per therm of delivered natural gas, and enabling
  customers to save energy and switch to renewable options that will
  avoid the equivalent of 18 million metric tons of carbon emissions.
• By investing in natural gas infrastructure, including accelerated pipe
  replacement programs in all three of its jurisdictions, Washington Gas
  has been able to reduce the emissions intensity from its natural gas
  distribution system by 20 percent.
• In addition, Washington Gas energy efficiency programs help its
  natural gas customers save energy and reduce costs. The company was
  recently selected
  as a distinguished leader in initiatives supporting ENERGY STAR
  ® -certified natural gas products and rebates, including
  ENERGY STAR smart thermostat and natural gas water heater promotions
  which resulted in high customer participation.

In 2017, Washington Gas was named as a Most
Trusted Brand and Customer
Champion utility company by Cogent Reports. Washington Gas serves
more than 1.1 million customers in the Washington D.C. area, and has
delivered safe, affordable and reliable natural gas for 170 years.
