The German Greens did very well in recent elections. As you report, they became junior partners of the Social Democratic Party (SDP) in Rhineland-Palatinate, and SDP became their junior partner in Baden-Württemberg, where the Greens will take control of the state government for the first time (“A Greener Future?” April 2, 2011). “In government,” you point out, “the Greens will inevitably suffer wear and tear.” Inevitably, indeed. “But the opportunity is great,” you add. “The party has been trying to escape from its environmental ghetto.” As Baden-Württemberg is Germany’s showcase economy, the chances of marrying market economy to sustainability are pretty good. One would thus hope that the victorious party will soon turn into Germany’s showcase Greens. And an example not only to other German states, but to the rest of Europe and beyond. Good examples are needed, too. Without direct involvement in the government, organizations concerned with environmental issues have little chance of success anywhere around the globe.
