Smallholders account for a growing share of forest loss while holding a disproportionate capacity to conserve and restore forests. Yet most Reducing Emissions from Deforestation and Forest Degradation (REDD+) methodologies remain scale- and actor-neutral, offering no systematic mechanism to equitably support these highly vulnerable rural communities. This study pilots a vulnerability-based avoided deforestation methodology in the Curiaú Quilombola territory (Amapá, Brazil), integrating a livelihood-vulnerability filter with a locality-matched dynamic baseline built from 10 m MapBiomas land-cover data and an independent accuracy assessment. A survey of 123 of 505 households is used to compute Livelihood Vulnerability Indexes, which indicate that Curiaú presents a level of vulnerability consistent with eligibility for carbon finance under the applied framework. The dynamic baseline implies an annual deforestation rate of 0.70% and baseline emissions of 2,540 tCO<sub>2</sub>e, of which 2,032 tCO<sub>2</sub>e are conservatively creditable after a 20% buffer deduction. At illustrative prices of 20-40 US$ tCO<sub>2</sub>e<sup>-1</sup>, these credits would yield roughly US$40,000-80,000 yr<sup>-1</sup>, sufficient to support edge-forest protection and co-finance the restoration of some flood-affected cropland and pasture, but still insufficient to meet broader livelihood recovery and adaptation needs. An exploratory regenerative-agriculture scenario for existing agricultural mosaics indicates a potential for 180-350 tCO<sub>2</sub>e yr<sup>-1</sup> of additional carbon removals, roughly US$4,000-14,000 yr<sup>-1</sup>, which can further support livelihood resilience. This study shows that the vulnerability-based avoid-deforestation approach can not only expand high-integrity REDD+ accounting to smallholder territories but also function as a targeting and planning tool to direct climate finance where marginal incentives are more likely to influence land-use decisions within broader resilience and development strategies, depending on local socio-economic and ecological conditions.
