Indeed, the deep and pervasive market failures – in carbon emissions, biodiversity, and ecosystem services – are accelerating environmental risks and ecological scarcities, and undermining human well-being and social equity. That is why the link to governance and institutions at Rio+20 is just as important as the transition to a green economy: markets are human constructs that require rules and institutions to guide not only their direction, but also their boundaries.
事实上，市场的大失败随处可见——比如碳排放、生物多样性、生态系统功能等——并在加剧环境风险和生态稀缺，破坏人类福利和社会公平。这就是为什么Rio+20的把治理与制度联系起来与向绿色经济转型同样重要：市场是一种人造结构，要求规则和制度指导方向并规定边界。
