The Reflections series synthesizes lessons from past evaluations to support organizational learning about what works and what doesn't. This paper examines past evaluations to provide seven lessons on integrated approaches to health, climate and energy:

1. Advocating for innovation
2. Adopting and implemented integrated policies
3. Intersectoral collaboration
4. Building climate-resilient health systems and communities
5. Promoting data-driven decision-making
6. Tailored capacity building
7. Inclusive financing

In promoting an integrated approach to health, climate and energy, UNDP collaborates with various global, regional and national partners such as the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM), the Global Environment Facility (GEF) and the Green Climate Fund (GCF) to develop and implement solutions that deliver multiple benefits. 

Development of this paper leveraged a combination of AI-led searches in UNDP's AIDA (Artificial Intelligence for Development Analytics) tool and human-led analysis. This paper draws on 60 evaluations published between 2018 and 2024. The sources include country-level and thematic evaluations conducted by UNDP’s Independent Evaluation Office and quality-assured decentralized evaluations commissioned by UNDP country offices.
