CHICAGO -- September 30, 2013

Two separate global authorities on corporate sustainability – the Dow Jones
Sustainability Indices (DJSI) and CDP – have recognized Exelon for its
sustainability performance and climate change performance and reporting.

DJSI and sustainability investing specialist RobecoSAM named Exelon to the Dow
Jones Sustainability North America Index for the eighth year in a row. The
achievement distinguishes Exelon as a consistent industry leader in corporate
sustainability based on a rigorous assessment of the company’s economic,
environmental and social performance.

Exelon was included in the index for placing among the top 20 percent of North
American utility companies based on responses to more than 100 questions
covering corporate governance, risk management, environmental performance,
human resources development, corporate citizenship, and health and safety.

“We have an obligation to our customers, communities, employees and
shareholders to operate our business in a way that is economically,
environmentally and socially sustainable, and we take that responsibility very
seriously,” said Christopher M. Crane, president and CEO of Exelon. “This
recognition validates our long-term commitment to improving sustainability
performance at all levels.”

Recognized for carbon emissions performance, disclosure

In addition to DJSI, CDP named Exelon to both its Global 500 Climate
Disclosure Leadership Index (CDLI) and its Climate Performance Leadership
Index (CPLI) for the second year in a row. No other U.S.-based utility company
appeared on either the Global 500 CDLI or CPLI.

These annual indexes, based on analysis by PwC, recognize companies that lead
their industries worldwide in the disclosure of information regarding their
carbon footprints, climate change strategies and risk management, and in
taking action on climate change mitigation, adaptation and transparency. The
top 10 percent of responding companies, based on the completeness and quality
of their CDP submissions, are named to the indexes. Exelon received a carbon
disclosure score of 98 out of 100 in 2013 – an increase from its score of 94
in 2012 – and again fell within the “A” band, the highest performance band for

Exelon also was one of only two utility companies named to the S&P 500 CDLI
and CPLI, indexes that recognize the top 10 percent of responding U.S.
companies from the S&P 500.

“Companies that score highly enough to be included in the Climate Disclosure
Leadership Index are responding to the call for greater corporate climate
accountability,” said Paul Simpson, chief executive officer of CDP. “They have
demonstrated leading practice for the measurement of greenhouse gas emissions
and energy use and transparency of their climate change strategy.”

The foundation of Exelon’s climate performance is Exelon 2020, a program that
drives the company toward a goal of reducing, offsetting or displacing 17.5
million metric tons of greenhouse gas emissions per year by 2020. Exelon
increased its goal from its original target of 15.7 million metric tons to
account for its merger with Constellation in March 2012. As of the end of
2012, Exelon had achieved more than 89 percent of the original goal.

In addition to Exelon 2020, Exelon had numerous achievements in the area of
corporate sustainability last year. For example, the company:

  *Added nearly 500 megawatts (MW) of new, clean generating capacity –
    including 404 MW in new wind projects, 31 MW in new solar and 63 MW in
    nuclear power uprates – creating jobs, tax revenue and shareholder value;
  *Donated nearly $28 million to nonprofit organizations and provided more
    than 105,000 hours of employee volunteer service in its communities;
  *Supported certified minority- and women-owned businesses with more than
    $750 million in Exelon business;
  *Made substantial contributions to the economic health of its communities,
    paying $13.1 billion for materials, goods and services; $8.0 billion in
    compensation, benefits and contracting expenses; and $1.7 billion in
    dividends, interest and taxes; and
  *Achieved its best-ever industrial safety performance.
