Ok, this is what it was all about:
http://www.ecocongregation.org/
The basic idea is that as parish communities we should be taking more action and more environmental responsibility. Parishes make their own plans and carry through what is right for them. The speaker broke it down into three areas:
Worship - using worship to teach congregation about Christian stewardship and green issues
Work - making church buildings, grounds, and products used Fair Trade and environmental
Witness - taking the green message into the community, and being the ones driving wider change within communities
All very practical really. Our church is already a Fair Trade church but there is more that can be easily done I think in terms of some environmental things.
