Germany says it will lobby for a tougher European Union goal to cut greenhouse gases.
Environment Minister Norbert Roettgen said Wednesday Germany wants the EU to commit to cutting its emissions by 30 percent by 2020.
The current unilateral commitment is a 20 percent cut.
He says the recession already has brought the 20-percent-goal within reach and Germany supports the switch to 30 percent.
He says he expects the EU commission to offer a proposal at the end of May.
The EU decided in 2007 it will bring down its emissions 20 percent below 1990 levels by 2020 in any case, and 30 percent if other industrial nations commit to similar goals in an international climate change treaty.
Environmentalists have urged the EU to drop that condition.
