Comerica's actions to reduce carbon emissions and mitigate the risks of
climate change have been recognized by CDP, the world's only global
environmental disclosure system. The achievement is announced in the CDP S&P
500 Climate Change Report 2013, which tracks how America's largest listed
companies are responding to a changing climate.

At the request of 722 investors representing $87 trillion in assets, Comerica
took part in CDP's climate change program, designed to increase awareness of
how to achieve efficiencies, realize monetary savings and capitalize on
commercial opportunities from the management of energy, carbon emissions and
climate change.

Achieving an 'A band' for climate performance is a prerequisite for a position
on the leadership index, which is based on a number of criteria associated
with measuring, verifying and managing carbon footprints.Some 36 S&P 500
companies are featured in the 2013 Climate Performance Leadership Index.

"Comerica is pleased with the recognition by CDP for our bank's management of
climate change-related risks and opportunities," said J. Scott Beckerman,
senior vice president and director of Corporate Sustainability for Comerica.
"We are proud to be recognized in this exclusive group of companies committed
to creating sustainable, long-term value for shareholders and other
stakeholders.Our commitments to reduce greenhouse gas emissions and resource
consumption are being realized and it is due to colleagues across Comerica
that have been involved in these efforts."

Comerica's senior sustainability officer, Kristin Bloser added, "We've made
good progress in expanding our emissions management and reporting initiatives,
including our work with business partners in our supply chain and our efforts
to provide environmentally beneficial loans to our customers.Comerica looks
forward to further embedding sustainability into our organization and
continued progress towards meeting our emissions reduction goal."

Tom Carnac, President for CDP in North America said:  "American companies
protecting themselves against climate risks and preparing to capitalize on the
opportunities a changing climate presents are building competitive advantage.
Increasingly we are seeing that taking action to address climate change is
good for business, so I am very pleased to see more US companies recognized in
the CPLI than ever before."
