We're pleased to announce the launch of our partner Interfaith Power and Light's 10% Challenge, which encourages congregations to cut their carbon footprint by 10%.

This is a big effort, which will reach hundreds of communities of faith, who will choose from a variety of activities to participate in. Some groups will perform energy audits, others will switch to more efficient lighting in their churches.

Not only will these actions help get Interfaith Power and Light to their own 10:10 commitment, but many of them will plan work parties as well!

In other faith partnership news, we've just begun working more closely with members of the Episcopal communion, who will be taking part in the big day.
