The ongoing international climate negotiations involve many specific topics, each of which involves its own interests, and revolve around the five elements of the Bali road map, namely, the vision, medium-term mitigation targets, adaptation, technology and funds. Funding is the basis for coping with climate change, and mitigation, adaptation and technology need stable and sustainable funding sources. To meet the demand for funds, on the one hand, we must rely on the market to promote the flow of funds, on the other hand, we need to raise non-market public funds. In order to continue to promote the fund problem within the framework of the Convention, many countries have put forward many new suggestions on establishing a new special-purpose fund mechanism. Issues related to the management of the financial mechanism, including the source and allocation of funds, the obligation to report to the COP, balance among member States, transparency and ease of use, have also attracted the attention of all Parties. In view of the possible dispersion of funds among different mechanisms, some countries suggested that under the guidance of the Conference of the Parties, an umbrella financial mechanism framework could be established for unified coordination and management. In addition to the negotiations outside the framework of the Convention, the emerging financial mechanism outside the framework of the Convention has attracted much attention. The trust funds funded by Britain, Japan and the United States and operated by the World Bank include three specific funds, namely, the Clean Technology Fund, the Forest Investment Fund and the Climate Resilience Demonstration Fund, and the Strategic Climate Fund, which is mainly used to support projects to mitigate and adapt to climate change through cooperation with regional development banks.
