Alli Gold Roberts says the business community is a bigger supporter of addressing climate change than you might think.

A senior manager for state policy at Ceres, which works with Fortune 500 companies and other business groups in addressing sustainability issues, Roberts said many businesses view climate change from a perspective of self-interest. Transportation, for example, accounts for more than a third of greenhouse gas emissions in New England. Business leaders want to reduce those emissions, but they also want to reduce congestion and improve public transit so their employees can get to work and their products can get to market.

Roberts joined James Aloisi, a board member of TransitMatters, and Stacy Thompson, executive director of the Livable Streets Alliance, on this week’s Codcast. They discussed the role businesses and their employees can play in addressing greenhouse gas emissions in the transportation sector.
