CN RECOGNIZED FOR SUSTAINABILITY LEADERSHIP AND LISTED ON THE DOW JONES SUSTAINABILITY WORLD INDEX FOR 12TH STRAIGHT YEAR

Canadian National Railway Company has again earned a place on the World and North American Dow Jones Sustainability indices (DJSI World and DJSI North America), for the 12th and 15th consecutive year respectively.

"We are thrilled to once again be recognized for our commitment to being a leader in sustainability. At CN, sustainability is core to how we do business and an essential part of our culture. Our inclusion on the prestigious Dow Jones Sustainability indices is a testament to our team of railroaders who make it their mission to deliver responsibly every day, in all areas of our business for all our stakeholders."

Ghislain Houle, executive vice-president and chief financial officer at CN, released its 2022 sustainability data supplement report earlier this year which outlines key performance metrics in the areas of environment, safety, people, community and economy.

CN's ninth Delivering Responsibly sustainability report will be released later this week and provide an update on the company's progress against its sustainability pillars, strategy and progress toward targets. CN is proud to be recognized as a global leader in sustainability with recognition from DJSI based on the transparent, comprehensive and consistent disclosure it delivers.
