ecbi made a submission on the a proposal for Climate Solidarity Alliance Solidarity Bonus Mechanism in July 2025 in response to a call for proposals for Mechanisms for Enhancing and Redistributing Revenues from Solidarity Levies by the Secretariat for the Global Solidarity Levies Taskforce (GSLTF). The proposal is that members of the GSLTF Coalition could participate in the Climate Solidarity Alliance (CSA) to provide support for climate change-related activities in developing countries, particularly through building resilience (adaptation) and responding to loss and damage due to the adverse impacts of climate change. 

The CSA is envisioned as a partnership of national and sub-national actors willing to show solidarity with the poorest and most vulnerable to help them deal with climate change. This voluntary partnership is envisioned as bottom-up to enable immediate action and to avoid the complexities of international agreements. 

The main elements of the proposed CSA are:

• national Climate Solidarity Trust Funds (CSTF) with loss and damage or adaptation windows, the Fund to Respond to Loss and Damage (FRLD) and the Adaptation Fund (AF) ideally placed to support the establishment of and provide standards for such national trust funds, and the use of Climate Solidarity Levies (CSLs); and
• a Solidarity Bonus Mechanism (SBM) under which eligible developing country CSA partners (‘solidarity recipients’) that contribute voluntarily to the FRLD or AF would receive the contributed amount along with a ‘solidarity bonus’ from the solidarity-providing CSA partners (‘solidarity providers’) as bilateral SBM payments directly into the CSTF of the solidarity recipients. thus incentivising their participation. A Solidarity Exchange, a (web-based) platform on which solidarity recipients can advertise their intention to contribute to an eligible multilateral climate fund, and solidarity providers could indicate whether they will be providing a bonus-compensation for (a share of) the advertised proposed contribution.
