Mesa County Libraries and Grand Valley Citizens’ Climate Lobby will host "Understanding your carbon footprint, carbon off-sets, and carbon pricing" with speakers Susan Atkinson and John Purser on May 7 at 12:00 pm (Clifton Branch Library) and 6:00 pm (Central Library).

As volunteers for the nonpartisan Citizens’ Climate Lobby, Susan and John will share their passion and knowledge regarding making wise, climate friendly choices in your daily life. Subjects will include details on the full life-cycle of the carbon footprint of a product, greenhouse gas emissions and how they can be offset with voluntary carbon credit, carbon pricing and how it can have the greatest cumulative effect from collective use of clean energy alternatives. The events is free and open to the public.
