ExxonMobil Announces Greenhouse Gas Reduction Measures

• Methane emissions to drop 15 percent, flaring reduced by 25 percent by
  2020
• Improving industry-leading energy efficiency in refining and chemical
  manufacturing

IRVING, Texas–(BUSINESS WIRE)–ExxonMobil
today announced greenhouse gas reduction measures that are expected to
lead to significant improvements in emissions performance by 2020,
including a 15 percent decrease in methane emissions and a 25 percent
reduction in flaring. The company also announced its intention to
improve its industry-leading energy efficiency in refining and chemical
manufacturing facilities.

ExxonMobil invests in lower-emission energy solutions such as
cogeneration, flare reduction, energy efficiency, biofuels, carbon
capture and storage and other technologies. ExxonMobil has spent more
than $9 billion on lower-emission energy solutions since 2000.

ÔÇ£We have a longstanding commitment to improve efficiency and mitigate
greenhouse gas emissions,ÔÇØ said Darren W. Woods, chairman and chief
executive officer. ÔÇ£TodayÔÇÖs announcement builds on that commitment and
will help further drive improvements in our business.ÔÇØ

ExxonMobil is undertaking a number of initiatives to significantly
reduce methane emissions. XTO EnergyÔÇÖs leak-detection-and-repair efforts
and operational improvements at U.S. production and midstream sites have
reduced estimated methane emissions across ExxonMobil operations by 2
percent in the past year. Combined with additional measures outside the
U.S. focused on the most significant sources of methane, ExxonMobil
expects to achieve a 15 percent reduction of methane emissions by 2020
compared with 2016.

ExxonMobil is one of eight global energy companies that supports guiding
principles on methane reduction. The principles focus on continually
reducing methane emissions, advancing strong performance across gas
value chains, improving accuracy of methane emissions data and
advocating sound policies and regulations on methane emissions.
ExxonMobil is a founding member of the APIÔÇÖs Environmental Partnership,
which is focused initially on reducing methane and volatile organic
compound emissions.

Efforts associated with oil and gas production and processing are
expected to lower natural gas flaring across ExxonMobil operations by
about 25 percent by 2020 compared with 2016. The most significant
reductions are expected to occur in operations in West Africa and
include use of third-party infrastructure.

ExxonMobil is a charter member of the Global Gas Flaring Reduction
Public-Private Partnership, which is committed to developing commercial
opportunities to reduce flaring. The partnership is comprised of
oil-producing countries, international and state-owned oil companies and
the World Bank.

Further greenhouse-gas emissions reduction efforts will target
ExxonMobilÔÇÖs global refining and chemicals manufacturing network with
the goal of improving existing industry-leading energy efficiency
performance.

ExxonMobil is the most energy efficient refining company in the U.S. and
internationally. The company has achieved a 10 percent improvement in
energy efficiency across its global refining operations following an
effort launched in 2000. ExxonMobil refining operations ranked in the
first quartile for energy efficiency in every Solomon Refining Industry
Survey over the past decade. Advanced efficiency technologies and
techniques have helped ExxonMobilÔÇÖs chemical business reduce its net
greenhouse gas emissions intensity by nearly 7 percent since 2013.

ExxonMobil remains committed to mitigating emissions from its operations
and helping consumers reduce their emissions, including through
efficient fuels, lubricants and lightweight plastics.

ExxonMobil continues to support research that leads to technology
breakthroughs and participates in constructive dialogue on policy
options.
