Carbon footprint - A catalyst for life cycle assessment?

Carbon footprinting has a much broader appeal than LCA.... In [carbon footprinting], things are kept simple, and a carbon footprint is easy to calculate online... and the calculated value can easily be grasped.... It is certainly an eye opener when you discover that your next trip from Copenhagen to San Francisco has a carbon footprint of roughly 2 tons of CO2 (equivalents), or 20% of the carbon footprint of an average European in an entire year.
