A vision for the future

The objectives of Blueprint 2020, our current five-year strategic plan, reflect a careful consideration of where our resources and expertise can have the biggest impact.

Decades of new ideas: In 1975, we were the first environmental group to hire economists to help solve environmental problems. More recently, an environmental data project with Google Earth Outreach is one of the first of its kind.
