In the context of meaningful mitigation actions and transparency on implementation, developed countries commit to a goal of mobilizing jointly USD 100 billion dollars a
year by 2020 to address the needs of developing countries.
这个是到2020年每年支付100 billion;还是到2020年大家讨论决定从2020年开始每年支付100 billion.
经济学人杂志，好像支持后者。"and aspires to a long-term system that would, in principle, provide $100 billion a year for mitigation and adaptation from 2020 onwards."
