As a result, the talks were transformed into a full-blown leaders’ summit, with presidents and prime ministers heading to Denmark to seal the deal themselves. But the talks failed to deliver a comprehensive, legally binding agreement, causing investors to lose confidence in a low-carbon economy and delaying progress by several years.
上一次联合国气候变化会议于2009年12月在哥本哈根召开。在那次会议期间，有全球团体对政府施压。结果，此次谈判演变成了领导人峰会，各国总统和总理纷纷涌向丹麦，亲自上阵谈判。但谈判并没有形成全面的、具有法律约束力的协定，这让投资者们对于形成低碳经济的信心大减，也将这方面的进展推迟了数年之久。
