CN maintains leadership role in 2010 Carbon Disclosure Project corporate
surveys in Canada and around the world

MONTREAL, Nov. 10 /CNW Telbec/ - CN (TSX: CNR) (NYSE:CNI) said today it has been recognized for excellence in climate-change reporting among Canadian and global corporations surveyed by the Carbon Disclosure Project (CDP).

CN was named to the CDP's 2010 Canada 200 Carbon Disclosure Leadership Index for the second straight year - only 16 Canadian companies are so recognized - and saw its score on the CDP's Global 500 report rise to 82 per cent in 2010 from 77 per cent in 2009.

In 2010, the CDP - a not-for-profit organization backed by 534 institutional investors representing more than US$64 trillion of assets under management - surveyed more than 4,700 of the world's largest corporations on greenhouse gas emissions, the significant risks and opportunities related to climate change, and the actions they are taking to manage those risks and opportunities.

Claude Mongeau, president and chief executive officer of CN, said: "With a deepened commitment to addressing climate change, we are proud of our achievements over the past year and are pleased with the Carbon Disclosure Project's recognition of CN as a leader in climate change disclosure. CN's asset-lean precision railroading model, energy-efficient fleet acquisitions and focused fuel conservation practices have contributed to the reduction in CN's carbon footprint.

"CN intends to continue to extend sustainable operating practices to all aspects of its business, and will continue to work closely with its customers to help them reduce their own carbon footprint. We believe that innovative supply chain solutions will help drive this lower carbon agenda and expand recognition among customers and policymakers to the strong environmental benefits of rail technology."

In addition to running fuel-efficient operations, CN has pioneered modal shift protocols with the provinces of Alberta and British Columbia that allow companies to generate carbon offsets by shifting freight shipments to rail from truck.

CN has participated in the CDP for the past five years. The CDP holds the largest database of corporate climate change information in the world, making it available to institutional investors, corporations, policymakers and their advisors, public sector organizations, government bodies, academics and the public.
