Opportunities and challenges for financing women's, children's and adolescents' health in the context of climate change.

Women, children and adolescents (WCA), especially in low-income and middle-income countries (LMICs), will bear the worst consequences of climate change during their lifetimes, despite contributing the least to global greenhouse gas emissions. Investing in WCA can address these inequities in climate risk, as well as generating large health, economic, social and environmental gains. However, women's, children's and adolescents' health (WCAH) is currently not mainstreamed in climate policies and financing. There is also a need to consider new and innovative financing arrangements that support WCAH alongside climate goals.We provide an overview of the threats climate change represents for WCA, including the most vulnerable communities, and where health and climate investments should focus. We draw on evidence to explore the opportunities and challenges for health financing, climate finance and co-financing schemes to enhance equity and protect WCAH while supporting climate goals.WCA face threats from the rising burden of ill-health and healthcare demand, coupled with constraints to healthcare provision, impacting access to essential WCAH services and rising out-of-pocket payments for healthcare. Climate change also impacts on the economic context and livelihoods of WCA, increasing the risk of displacement and migration. These impacts require additional resources to support WCAH service delivery, to ensure continuity of care and protect households from the costs of care and enhance resilience. We identify a range of financing solutions, including leveraging climate finance for WCAH, adaptive social protection for health and adaptations to purchasing to promote climate action and support WCAH care needs.

Climate finance opportunities for health and health systems.

Climate change poses significant risks to health and health systems, with the greatest impacts in low- and middle-income countries - which are least responsible for greenhouse gas emissions. The Conference of Parties 28 at the 2023 United Nations Climate Change Conference led to agreement on the need for holistic and equitable financing approaches to address the climate and health crisis. This paper provides an overview of existing climate finance mechanisms - that is, multilateral funds, voluntary market-based mechanisms, taxes, microlevies and adaptive social protection. We discuss these approaches' potential use to promote health, generate additional health sector resources and enhance health system sustainability and resilience, and also explore implementation challenges. We suggest that public health practitioners, policy-makers and researchers seize the opportunity to leverage climate funding for better health and sustainable, climate-resilient health systems. Emphasizing the wider benefits of investing in health for the economy can help prioritize health within climate finance initiatives. Meaningful progress will require the global community acknowledging the underlying political economy challenges that have so far limited the potential of climate finance to address health goals. To address these challenges, we need to restructure financing institutions to empower communities at the frontline of the climate and health crisis and ensure their needs are met. Efforts from global and national level stakeholders should focus on mobilizing a wide range of funding sources, prioritizing co-design and accessibility of financing arrangements. These stakeholders should also invest in rigorous monitoring and evaluation of initiatives to ensure relevant health and well-being outcomes are addressed.

Le changement climatique fait peser des risques considérables sur la santé et les systèmes de santé, affectant principalement les pays à revenu faible et intermédiaire ­ alors qu'ils contribuent le moins aux émissions de gaz à effet de serre. Lors de la Conférence des Nations Unies sur le changement climatique de 2023, la 28e Conférence des Parties a abouti à un accord sur la nécessité d'adopter des approches de financement équitables et holistiques pour résoudre la crise climatique et sanitaire. Le présent document offre un aperçu des dispositifs de financement climatique existants ­ à savoir des fonds multilatéraux, des mécanismes de marché volontaires, des micro-taxes et une protection sociale adaptative. Nous évoquons la possibilité de recourir à ces approches en vue de promouvoir la santé, de générer des ressources supplémentaires pour le secteur de la santé et de renforcer la viabilité et la résilience des systèmes de santé; nous nous intéressons également aux défis que représente leur mise en œuvre. Nous suggérons que les professionnels de la santé publique, les responsables politiques et les chercheurs profitent de cette occasion pour obtenir des fonds climatiques afin d'améliorer la santé et de développer des systèmes de santé durables et adaptés au changement climatique. Souligner tout l'intérêt, pour l'économie, d'investir dans la santé peut aider à inscrire la santé en priorité dans les initiatives de financement climatique. Réaliser des progrès significatifs implique que la communauté internationale prenne conscience des enjeux sous-jacents en matière d'économie politique, enjeux qui ont jusqu'à présent limité le potentiel du financement climatique dans l'atteinte des objectifs de santé. Pour y remédier, nous devons restructurer les institutions financières afin d'accroître l'autonomie des communautés en première ligne face à la crise climatique et sanitaire, et de faire en sorte que leurs besoins soient satisfaits. Les efforts des parties prenantes à l'échelle nationale et mondiale doivent porter sur la mobilisation d'un large éventail de sources de financement, en mettant l'accent sur la conception conjointe et l'accessibilité des modalités financières. Ces parties prenantes doivent en outre investir dans un suivi étroit et une évaluation rigoureuse des initiatives pour veiller à obtenir des résultats pertinents en termes de santé et de bien-être.

El cambio climático plantea riesgos importantes para la salud y los sistemas sanitarios, con mayores impactos en los países de ingresos bajos y medios, que son los menos responsables de las emisiones de gases de efecto invernadero. La 28.ª Conferencia de las Partes en la Conferencia de las Naciones Unidas sobre el Cambio Climático de 2023 condujo a un acuerdo sobre la necesidad de enfoques de financiación holísticos y equitativos para abordar la crisis climática y sanitaria. Este documento ofrece una visión general de los mecanismos de financiación climática existentes, es decir, los fondos multilaterales, los mecanismos voluntarios basados en el mercado, los impuestos, los microimpuestos y la protección social adaptable. Analizamos el uso potencial de estos enfoques para promover la salud, generar recursos adicionales para el sector sanitario y mejorar la sostenibilidad y la resiliencia de los sistemas sanitarios. Sugerimos que los profesionales de la salud pública, los responsables de formular las políticas y los investigadores aprovechen la oportunidad de utilizar la financiación climática para mejorar la salud y los sistemas sanitarios sostenibles y resilientes al cambio climático. Destacar los beneficios más amplios de invertir en salud para la economía puede ayudar a priorizar la salud dentro de las iniciativas de financiación climática. Para lograr avances significativos será necesario que la comunidad mundial reconozca los problemas de economía política subyacentes que hasta ahora han limitado el potencial de la financiación para abordar los objetivos de salud. Para superar estos desafíos, necesitamos reestructurar las instituciones financieras para empoderar a las comunidades que se encuentran en primera línea de la crisis climática y sanitaria y asegurar que se satisfacen sus necesidades. Los esfuerzos de las partes interesadas a nivel mundial y nacional deben centrarse en movilizar una gran variedad de fuentes de financiación y priorizar el diseño conjunto y la accesibilidad de los acuerdos de financiación. Estas partes interesadas también deben invertir en la supervisión y evaluación rigurosas de las iniciativas para garantizar que se abordan los resultados pertinentes en materia de salud y bienestar.

An umbrella review of health co-benefits from actions to reduce greenhouse gas emissions.

BACKGROUND: There have been many modelled studies of potential health co-benefits from actions to reduce greenhouse gas emissions, but so far there have been no large-scale attempts to compare the magnitude of health and climate effects across sectors, countries, and study designs. METHODS: As part of the Pathfinder Initiative project an umbrella review of studies was done, and 26 previous reviews were identified with 57 primary studies included. Studies included in the review were required to have quantified changes in greenhouse gas emissions and health effects (or risk factors) from defined actions to reduce climate effects. Study data were extracted and harmonised by standardising impact measures per 100 000 of the national population (or urban population for city-level actions), averaging effects over a 1-year period and aggregating actions into their respective sectors by use of a predefined framework. FINDINGS: From 200 mitigation actions, the majority were in the agriculture, forestry, and land use sector (103 actions [52%]), followed by the transport sector (43 actions [22%]). The largest effects on greenhouse gas emissions were seen from actions in the energy sector, and these actions also had substantial health co-benefits in lower middle-income countries, although benefits were smaller in high-income settings. The greatest health benefits were seen from actions to change diets and introduce clean cookstoves. The major pathways to health were through reduced air pollution, healthier diets, and increased physical activity from switching to active travel modes. Effect sizes tended to be larger from national modelling studies and smaller from localised or implemented actions. INTERPRETATION: The potential co-benefits to health from actions to reduce climate change are large, but most evidence still comes from modelling studies and from high-income and middle-income countries. There are also major context-dependent differences in the magnitude of effects found, so actions need to be tailored to the local context and careful attention needs to be paid to potential trade-offs and spillover effects.
