ExxonMobil Chairman Highlights Commitment to Meeting Growing Energy Demand and Addressing Climate Risks

Speaking today at Chatham House, London, Rex W. Tillerson,
Chairman and Chief Executive of Exxon Mobil Corporation (NYSE:XOM),
discussed two critical energy challenges which the world currently
faces: meeting the economic needs of growing populations, especially
in developing countries, and addressing the risks of climate change.

Tillerson was speaking as part of Chatham House's new
International Business Leaders Programme.

He described the actions ExxonMobil is taking in partnership with
others to address both challenges, and also discussed a framework for
economic and climate change policymaking.

"It has become increasingly clear that climate change poses risks
to society and ecosystems that are serious enough to warrant action -
by individuals, by businesses and governments."

Reaffirming ExxonMobil's commitment to being a constructive and
active participant in dialogues concerning proposals to reduce
greenhouse gas emissions, Tillerson outlined the company's views on
important elements for policymaking. "We believe that maximizing the
use of markets to select and deploy technologies will best serve
society's interests in the long term and meet future energy needs.
Achieving a uniform and predictable cost for carbon across the economy
will enable market mechanisms to work effectively to this end."

He highlighted ExxonMobil actions to increase energy efficiency in
the short-term, advance current emission-reducing technologies in the
medium-term, and develop breakthrough technologies in the long term.
Citing ExxonMobil's long standing commitment to energy efficiency, he
said that steps the corporation has taken since 1999, resulted in the
avoidance of 12 million tonnes of greenhouse gas emissions in 2006
alone which is the equivalent to taking about two million U.S. cars
off the road.

In describing ExxonMobil's work with partners, Tillerson reported
that the company is working on an innovative fuel system using liquid
hydrocarbon fuels to generate hydrogen onboard vehicles, potentially
reducing emissions without the need for a dedicated hydrogen
distribution infrastructure. "We still have a long road ahead, but our
progress in making hydrogen-fueled vehicles commercially viable is
encouraging."

"We must care enough to treat the risks of global poverty and
global warming seriously," he concluded, "we need to manage the risks
effectively if we are to maximize the economic and environmental
benefits available to future generations.

NOTES TO EDITORS

-- The International Business Leaders Programme aims to encourage
debate amongst senior business figures on issues which bridge
the gap between international affairs, global business and
commerce. The inaugural event took place in November 2006 and
Rex Tillerson was the second speaker in this Programme.

-- The International Energy Agency estimates that, by 2030, it is
likely world energy demand will increase by 45 percent. This
growth equates to about 100 million barrels of oil equivalent
a day, which is in addition to the 240 million barrels oil
equivalent a day currently consumed.
