I stumbled over two modern concepts:
- You can calculate your CO2 emissions (by plance, car, etc.) and buy a so-called terrapass that balances your impact by investing the money in projects that reduce CO2 emissions somewhere else. A comparable institution out of Potsdam, Germany, is called TheCompensators*.
- The website with the magnificent title WorldChanging.com is set-up as a portal for ideas and tools that may change our thinking for the better. It "works from a simple premise: that the tools, models and ideas for building a better future lie all around us."
