Mapping Corporate Environmental Performance

A new real-time map allows researchers and activists to more easily identify corporate polluters, but also allows companies to showcase their environmental performance.

Called MapEcos, the website marries information about companies' environmental management, which is provided voluntarily by managers in real time, to companies' pollution data from the U.S. Environmental Protection Agency.

"Users can track factories' pollution activity over time, compare factories in their community, and compare the pollution of local factories to others in their industry across the country -- but just as important, monitor what mitigating steps facility managers are taking," according to an article in HBS Working Knowledge.

The resource was created by Harvard Business School's Michael Toffel with collaborators Andrew King and Michael Lenox.
