About the Calculator

Overview | FundingPrizes | Credits


Concord Conserves developed the carbon calculator and Conservation Challenge for Concord and Carlisle, MA students and residents to lower their impact on the environment as well as learn about how our lifestyles compare to others around the world.

The calculator and challenge includes 3 parts:

  1. The ability to measure the amount of carbon a household uses
  2. The ability to choose and quantify reductions of carbon by completing energy saving initiatives from a lengthy list of reductions
  3. A 'compete' feature whereby groups can compete against each other to see who can reduce the most.


We appreciate the generous donation of the following organizations for making the Challenge possible.

Concord Carlisle Community Chest, 2011 Field of Interest Funds Grant

First Parish of Concord Social Action Committee Grant

Concord Municipal Light Plant for donating funding for the prizes
