As it stands, it is acceptable for the EU to assume responsibility when its own health and environmental-protection measures function as de facto trade barriers. EU directives capping the CO2 emissions of cars, for example, are actually a kind of industrial policy aimed at protecting small French and Italian automobiles.
另一个潜在风险是投资保护。目前的情况是，在欧盟自身健康及环境保护措施实际起到贸易壁垒作用的情况下欧盟承担责任可以接受。比方说，欧盟设定汽车二氧化碳排放上限的指令实际是某种意在保护法意小型车的行业政策。投资保护能限制这种权力滥用。
