sions, the health impacts of air pollution are estimated to cost more than 4% of their GDP. Actions to meet the Paris goals would cost around 1% of global GDP. The report provides recommendations for governments on how to maximize the health benefits of tackling climate change and avoid the worst health impacts of this global challenge.
It describes how countries around the world are now taking action to protect lives from the impacts of climate change – but that the scale of support remains woefully inadequate, particularly for the small island developing states, and least developed countries. Only approximately 0.5% of multilateral climate funds dispersed for climate change adaptation have been allocated to health projects

pollution is estimated to cause millions of deaths and lost years of healthy life annually. The burden of disease attributable to air pollution is now estimated to be on a par with other major global health risks such as unhealthy diet and tobacco smoking, and air pollution is now recognized as the single biggest environmental threat to human health.

rities require information about current associations between health outcomes and weather or climate, vulnerable populations, projections of future risks and adaptation opportunities in order to reduce exposures, empower individuals to take needed protective actions and build climate-resilient health systems. An increasing number of health authorities from local to national levels seek this information by conducting climate change and health vulnerability and adaptation assessments. While assessments can provide valuable information to plan for climate change impacts, the results of many studies are not helping to build the global evidence-base of knowledge in this area. They are also often not integrated into adaptation decision making, sometimes because the health sector is not involved in climate change policy making processes at the national level. Significant barriers related to data accessibility, a limited number of climate and health models, uncertainty in climate projections, and a lack of funding and expertise, particularly in developing countries, challenge health authority efforts to conduct rigorous assessments and apply the findings. This paper examines the evolution of climate change and health vulnerability and adaptation assessments, including guidance developed for such projects, the number of assessments that have been conducted globally and implementation of the findings to support health adaptation action. Greater capacity building that facilitates assessments from local to national scales will support collaborative efforts to protect health from current climate hazards and future climate change. Health sector officials will benefit from additional resources and partnership opportunities to ensure that evidence about climate change impacts on health is effectively translated into needed actions to build health resilience.

The recommendations were developed in consultation with over 150 organizations and 400 experts and health professionals. They are intended to inform governments and other stakeholders ahead of the 26th Conference of the Parties (COP26) of the United Nations Framework Convention on Climate Change (UNFCCC) and to highlight various opportunities for governments to prioritize health and equity in the international climate movement and sustainable development agenda. Each recommendation comes with a selection of resources and case studies to help inspire and guide policymakers and practitioners in implementing the suggested solutions

climate change and health have made clear the need for a multi-sectoral approach to target the drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.

national, and local partners, implemented the Urban Health Initiative (UHI) pilot project in Accra, Ghana. The Initiative prompted the health sector to use its influential position to demonstrate to decision-makers and the public the full range of health, environmental and economic benefits that can be achieved from implementing local emission reduction and energy access policies and strategies. Policy tracking, although not always considered, is a fundamental component of this procedure. It assesses the planning, implementation and progress of a policy to refine or adjust policies with the final objective of increasing the likelihood of the policy being successful. This report is an outcome of the last component of the UHI model process, Policy tracking and monitoring outcomes. The report proposes a framework for tracking urban health policies, with a special focus on the impacts of air quality and energy access on human health and well-being in African countries, giving some examples from the pilot project in Accra. The report also provides resources to survey air quality in cities and other tools to assess public health and the environmental impacts of urban policies and monitor or track their effects.

od- water- and vector-borne diseases. Climate change will put pressure on environmental and health determinants, such as food safety, air pollution and water quantity and quality. A climate-resilient future depends fundamentally on reducing greenhouse gas emissions. Limiting warming to below 2 °C requires transformational technological, institutional, political and behavioural changes: the foundations for this are laid out in the Paris Agreement of December 2015. The health sector can lead by example, shifting to environmentally friendly practices and minimizing its carbon emissions. A climate-resilient future will increasingly depend on managing and reducing climate change risks to protect health. In the near term, this can be enhanced by including climate change in national health programming and creating climate-resilient health systems.

increasing in prevalence over the last decades, partly as the result of the impact of climate change. Increased sensitisation rates and more severe symptoms have been the partial outcome of: increased pollen production of wind-pollinated plants resulting in long-term increased abundance of pollen in the air we breathe; earlier shifts of airborne pollen seasons making occurrence of allergic symptoms harder to predict and deal with efficiently; increased allergenicity of pollen causing more severe health effects in allergic individuals; introduction of new, invasive allergenic plant species causing new sensitisations; environment-environment interactions, such as plants and hosted microorganisms, i.e. fungi and bacteria, which comprise a complex and dynamic system, with additive, presently unforeseeable influences on human health; environment-human interactions, as the consequence of a combination of environmental factors, like air pollution, global warming, urbanisation and microclimatic variability, which create a multi-resolution spatiotemporal system that requires new processing technologies and huge data inflow in order to be thoroughly investigated. We suggest that novel, real-time, personalised pollen information services, like mobile-app risk alerts, must be developed to provide the optimum first line of allergy management.

pollution that kills 7 million people every year, almost the same as the number of deaths caused by tobacco smoking.
In 2018, the World Health Organization (WHO) recognised air pollution as a major health risk factor. There is widespread public discussion about the effects of fossil fuel combustion and emissions on climate change… but what about the effect on our health? Climate change poses a threat not only to the health of the planet, but also to humans.
The case studies evaluated in this report offer examples of mechanisms that can be used to restrict the production and consumption of unhealthy commodities, so that the health, air pollution and climate communities can learn from one another, using shared approaches and language. These case studies show that the connection with health is a strong argument to support sustainable change.
