Green your work
The Green Office footprint calculator aims to help companies estimate carbon emissions. Telecommuting and teleconferencing prevent carbon pollution from planes, trains, and automobiles. To that end, online meeting services such as Cisco's WebEx and word processors such as Google Docs enable people to collaborate remotely. Tools to reduce paper usage include GreenPrint software, which shaves off extra pages from printing. Guides from WebEx and Office Depot have more tips. The OpenEco community encourages businesses to share strategies around sustainability.

If green jobs, such as installing solar panels, are to replace legions of positions lost in America's blue-collar, rust-belt sector, there's still a long way to go. However, some of the sites listing related jobs include Sustainable Business, Co-op America, Green Biz, and Treehugger. For those willing to work for free, VolunteerMatch lists opportunities related to the environment.
