OUR JOURNEY TOWARD SUSTAINABLE DEVELOPMENT

A SUMMARY OF THE 2001 REPORT ON SUSTAINABILITY

Since we first articulated our vision of becoming a sustainable energy company,
Suncor has embarked on a challenging, but rewarding journey - a journey that has
shaped our organization's culture, influenced our decisions and set the stage
for growth.

Through our journey towards this vision, we have made significant strides in
understanding what sustainability means, and how we can apply it to provide
energy solutions that meet or exceed the environmental, economic and social
needs and expectations of our stakeholders.

We have also become more aware of how much we still have to learn, and how far
we still have to go. However, each step we take helps us to earn the trust and
respect of stakeholders and supports our ability to operate responsibly, grow
our business and generate shareholder value.

This document summarizes the steps we have taken over the past two years to
become a sustainable energy company.

EXCERPTS FROM THE PRESIDENT'S MESSAGE

WORKING TOGETHER - WE ARE FINDING SOLUTIONS

THE ENERGY DILEMMA

Meeting the growing demand for low-cost energy while addressing economic,
environmental and social concerns is a dilemma faced by Suncor, the energy
industry, government and society. On one side, we have increasing demand for
energy, and concerns about rising energy prices and regional electricity
shortages. On the other side, there are ever-increasing concerns about the
environmental consequences of increased development and use of hydrocarbon
energy sources such as oil, natural gas and coal.

To resolve these differences we must acknowledge the legitimacy of both
perspectives and strive for solutions that accommodate both needs.

PARALLEL PATHS

Suncor has adopted a parallel path approach to energy development - using the
strength of our current core business as a producer of hydrocarbon energy to
simultaneously advance renewable energy for the longer term.
<PAGE>


Suncor's core business is the pursuit of hydrocarbon development. This reflects
the reality that our existing residential, commercial and transportation
infrastructure is reliant on hydrocarbons, the most abundant, reliable and
inexpensive source of energy.

Renewable energy offers great promise and needs to be a growing part of our
world energy supply. We intend to be a front-runner on the road to energy
diversification because we believe consumers will increasingly demand
alternative and renewable energy choices.

COLLABORATION

One of the most important lessons we have learned on our journey towards
sustainability is that more progress is made on issues if we concentrate on
dialogue rather than debate and seek integrated and mutually beneficial
solutions.

Sustainability is not a solitary pursuit. It is more effective if it is a
collaborative effort.

Suncor Energy's vision is to be a unique and sustainable energy company,
dedicated to vigorous growth in worldwide markets by meeting the changing
expectations of our current and future stakeholders. Suncor's vision of becoming
a sustainable energy company integrates the environmental, economic and social
needs and expectations of our stakeholders.

ENVIRONMENTAL PERFORMANCE SUMMARY

Suncor recognizes the need to reduce the environmental impact associated with
the development, production and use of hydrocarbon energy.

o    By 2000, greenhouse gas emissions increased 12% from 1996 at the same time
     total production increased by 21%. This represents a decrease in emission
     intensity of more than 6% over the same period.

o    Sulphur dioxide emissions were at historically low levels in 2000 and more
     than 17% lower than in 1999. These emissions have decreased by 70%
     since 1996.

o    Nitrogen oxide emissions in 2000 were 67 tonnes per day, more than double
     the 1996 level of 28 tonnes per day.

o    In 1999 and 2000, water discharged by Oil Sands to the Athabasca River
     met water quality requirements 100% of the time. Water discharged to
     the St. Clair River by Sunoco met all water quality standards except
     for one occurrence in each of 1999 and 2000.
<PAGE>


o    At the end of 2000, Oil Sands had reclaimed 9% of the total land
     disturbed. It is projected that without further development, this
     figure could increase to about 26% by 2010 and 42% by 2020.

o    In 2000, we had four major environment, health and safety incidents,
     compared with 15 in 1996.

ECONOMIC PERFORMANCE SUMMARY

Economic performance is a fundamental component of Suncor's vision of being a
sustainable energy company.

o    From 1996 to 2000, Suncor's common share price rose 170%.

o    In 2000, production was 141,100 barrels of oil equivalent per day, a 21%
     increase over 1996 levels.

o    Net earnings were $377 million in 2000, more than double the level
     achieved in 1996.

o    In 2000, our capital expenditures totaled nearly $2 billion - three and
     a half times the amount of these investments in 1996 - as we acquired
     materials and services for operation and expansion of our business.

o    Since 1996, Suncor has paid almost $2.5 billion in taxes and royalties.

o    In September 2001, Suncor was again listed on the Dow Jones
     Sustainability Index. This is the third year in a row that Suncor has
     been selected.

SOCIAL PERFORMANCE SUMMARY

Suncor is committed to improving the quality of life in the communities where
our employees work and live.

o    Lost-time injury frequencies for both employees and contractors were
     down about 40% in 2000 from 1996. Our total recordable injury
     frequencies were approximately 35% and 55% below 1996 levels for Suncor
     employees and contractors respectively.

o    In 2000, we increased Aboriginal employment to 9% of the full-time
     permanent Oil Sands workforce, compared with 3% in 1996.

o    Suncor's permanent workforce in 2000 increased by 31% over 1996. Our 2000
     payroll for  employees, totaled $260 million, an increase of 22% from 1997.
<PAGE>


o    Since 1986, Suncor and the Communications Energy and Paperworkers Union
     Local 707 in Fort McMurray have negotiated six collective agreements
     without disruption. The most recent three-year agreement was signed in
     June 2001.

o    In 2000, the Suncor Energy Foundation donated nearly $3 million to almost
     300 charitable causes.

SUSTAINABLE GROWTH

Suncor intends to help meet consumer demand for energy through responsible
development of hydrocarbon resources while also supporting diversification
through alternative and renewable energy sources. Integrating the need to
increase shareholder value with our commitment to reduce environmental impact
and contribute to the well-being of society is a key component of Suncor's
growth strategy.

SUNCOR'S GROWTH STRATEGY

As conventional supplies of oil and gas are depleted in Canada, the Athabasca
oil sands industry of Alberta becomes an increasingly important source of
energy. Project Millennium, an expansion of our Oil Sands business, is expected
to increase production capacity from 115,000 barrels of oil per day to 225,000
barrels per day by 2002. Our longer-term vision is to increase production
capacity to 450,000 barrels per day in 2008.

In early 2000, Suncor announced plans to invest $100 million in alternative and
renewable energy over the next five years. Our vision for this business is to be
a full-service developer of renewable green power, providing consumers with
energy options that have environmental benefits and are competitively priced.

INVESTING IN ALTERNATIVE AND RENEWABLE ENERGY

Suncor's alternative and renewable energy business is focused on investments in
wind power, solar power, run-of-river hydroelectricity and energy produced from
biomass and municipal solid waste. Suncor has created a long-term strategic
plan, reviewed more than 700 opportunities and in April 2001, took a major step
forward in providing wind power in Canada by partnering with Enbridge Inc. to
build a $20 million wind power project in Gull Lake, Saskatchewan. When fully
commissioned, the SunBridge Wind Power Project is expected to increase Canada's
generation of power from wind by approximately 10%.

Suncor Energy Inc. is a growing Canadian integrated energy company with more
than $6.8 billion in assets and production of approximately 141,100 barrels of
oil equivalent per day. The company has about 3,000 employees and has been
active in Canada for over 80 years. Currently, Suncor is comprised of three
businesses focused on the exploration, production and marketing of crude oil,
natural gas and petroleum-based products.
