Small-scale actors, particularly micro, small, and medium enterprises (MSMEs) and non-governmental organizations (NGOs), play a vital role in building climate resilience and adaptation through their unique ability to engage local communities and implement targeted, context-specific solutions. These organizations serve as critical bridges between international climate commitments and local action in the small island state of Trinidad and Tobago (T&T), contributing significantly to the nation’s climate resilience goals. Despite their essential role, these actors often receive inadequate institutional support and resources, and their contributions to climate action frequently go unrecognized. Through qualitative case study analysis of eight successful climate resilience initiatives led by MSMEs and NGOs, five key themes emerged: the critical importance of translating climate science into accessible, everyday language; a pervasive resistance to change within T&T that hinders the implementation of climate-focused projects; the intrinsic connection between community engagement and climate resilience; a significant disconnect between governmental policies and community needs; and specific factors that determine the effectiveness of small-scale climate interventions. The findings reveal fundamental challenges within T&T’s climate action landscape, including communication barriers, cultural resistance, and financing constraints that limit smaller organizations’ ability to implement crucial climate projects. These themes illuminate the complex interplay between socio-economic conditions, cultural mindsets, and institutional structures that shape the nation’s climate resilience efforts. The research underscores the urgent need to reassess and restructure T&T’s climate ecosystem to address these persistent challenges, bridge institutional gaps, and strengthen the country’s collective capacity to achieve its climate goals while enhancing community resilience.
