About BASE


Communities in the Global South are in the frontline of the impacts of climate change and, at the same time, play a crucial role in preserving traditional knowledge and generating innovative solutions for reducing emissions and building resilience. However, despite their significance, locally led projects face significant challenges in accessing climate funds. One such obstacle involves the requirement of developing a “climate rationale”. A climate rationale refers to the narrative and evidence gathered to show that a project intends to reduce greenhouse gas emissions and climate change impacts, and that it will be fit for a changing climate. Often, justifying the extent to which a proposal will effectively address climate change requires many studies and is highly time and resource-consuming, becoming an obstacle for funds to quickly and effectively reaching those who need it most to drive the transition.

To tackle the climate rationale challenge, BASE (Building Approaches to fund local Solutions with climate Evidence) was launched to promote more and better access to climate finance for local communities, by testing alternative approaches to develop the climate rationale of projects with more speed, simplicity and in a manner that resonates with communities. This is a collaborative Initiative coordinated by Fundación Avina, as part of its Resilience and Climate Transition Program, and integrated by a diverse plenary of partners and aligned initiatives.


The Initiative’s main goal is to generate evidence, through the implementation of a diverse range of grantmaking schemes, on how the development of the climate rationale of projects can be simplified and serve as a proof-of-concept of alternative, community-led approaches to labelling this type of finance as ‘climate finance’ and then take these learnings to advocate in the climate funding landscape. Each grantmaking scheme (or track) will be a specific call to “test” a particular approach to develop a climate rationale, that might also vary in focusing on different sectors or areas.

BASE addresses the climate rationale challenge pragmatically and with a view toward systemic change, by convening local organizations, funders, knowledge organizations, and intermediaries to build solutions through a strategy built on three pillars: FUNDING, LEARNING, AND SCALE.

BASE’s track of grants will implement concrete actions to combat the climate crisis (including mitigation, adaptation and loss & damage) and unravel new approaches to develop the climate rationale of projects. BASE will provide a concrete input to the climate finance landscape to the need to streamline the development of a solid climate rationale that can help distinguish a climate project from environmental or development initiatives. This differentiation can serve as evidence of the funding’s impact and to ensure accountability in addressing this urgent global challenge.
