The president of the European Commission promised that while the European Union’s climate policies are “not cost-free,” they would amount to just 0.5% of GDP. Indeed, politicians of all stripes have reiterated the Stern Review’s finding that global warming can be curtailed by policies costing just 1% of world GDP.
我们被告知解决气候变化问题可以大幅降低所付出的代价。欧盟委员会主席承诺虽然欧盟气候政策“并非毫无成本”，但只占GDP的0.5%。事实上，各路政要重申了斯特恩报告的观点，即可以通过仅占全球GDP1%的成本成功控制全球变暖。
