A brief description of the innovative policy, practice, program, or outcome :

Yale Carbon Calculator

The Yale Community Carbon Fund developed a Yale specific carbon calculator to help members of the Yale community calculate emissions associated with Yale related events, commuting, and travel. By providing the Yale community a carbon calculator that assess their direct carbon impact we hope to educate people about the choices they make when planning events, commuting, and traveling. Ultimately, we hope that the Yale community will use the calculator as a tool for making less carbon intensive choices when it comes to event planning, commuting, and selecting transportation options.

Using monthly utility data for each building on Yale's campus and emission factors associated with Yale power plants and the local electricity grid, the carbon calculator allows users to better understand the greenhouse gas emissions associated with any event they may hold on campus.

Additionally, regional and national emission factors were used to estimate greenhouse gas emissions associated with transportation and waste.
