Laissez-faire, Kooperation oder Alleingang: Klimapolitik in der Schweiz

Today it seems neither economically and ecologically efficient, if Switzerland reduces its carbon-dioxide (C02) emissions in a national solo-run. But calculations from a dynamic general equilibrium analysis show: If at high probability an international agreement on C02 reductions will be established in the future, then it is economically rational, to start today a moderate climate policy in Switzerland. On the one hand, at the beginning economic costs of a solo-run are not higher than the costs of participating in an international climate program. On the other hand, only the solo-run provides an economic incentive which is strong enough such that existing technologies and structure will be replaced by less emitting and more efficient ones.
