欧盟近几年来在环境问题上出台了一系列的政策,如到2020年,温室气体排放量在1990年的水平上减少20%等,这些目标旨在推动《京都议定书》的签署。欧盟有着长远的领导力目标,但这项计划进行的并不顺利。欧盟外交的成功依赖于致力减少温室气体排放的政策,但是其成员国多元的经济形势以及政治上的一体化程度差等问题导致其在国际上推进环境政策陷入尴尬的局面,显得异常脆弱。 In recent years, the EU has enacted a series of policies on environmental issues. For example, by 2020, the amount of greenhouse gas emissions will be reduced by 20% at the level of 1990. The goals are to promote the signing of the “Kyoto Protocol.” The EU has long-term leadership goals, but the plan is not going well. The success of the EU diplomacy relies on policies aimed at reducing greenhouse gas emissions. However, due to its diverse economic situation and poor political integration, EU diplomacy has become extremely vulnerable as it embarks on an embarrassing situation in advancing environmental policies internationally.
