Berlin (dpa) - The Greens go the well-known considerations of the Federal Government on climate change not far and not fast enough. The plans were far from sufficient, said party leader Robert Habeck. CO2 emissions would have to be priced from next year and emissions would be reduced on the basis of verifiable, annual targets. An effective and rapid option is to first set a minimum price through a tax, which then turns into a trading system from certificates in the coming years.
