EPA has developed an online emissions calculator to help individuals (and households) reduce their own contributions to U.S. greenhouse gas emissions. Use this online calculator to obtain an estimate of your personal greenhouse gas emissions or your family's greenhouse gas emissions. After assessing your emissions, you may then move on to the next section of the calculator to explore actions you and/or your family can take to lower your emissions while reducing your energy and waste disposal costs.

Environmental Protection Agency CIO Molly O'Neill spoke with GCN about a successful wiki-based pilot involving the Puget Sound Leadership Council, in addition to the challenges agencies face handling large amounts of data.
