This document presents the World Health Organization (WHO) operational framework for building climate resilient health systems. The framework responds to the demand from Member States and partners for guidance on how the health sector and its operational basis and health systems can systematically and effectively address the challenges increasingly presented by climate variability and change. This framework has been designed in light of the increasing evidence of climate change and its associated health risks; global, regional and national policy mandates to protect population health; and a rapidly emerging body of practical experience in building health resilience to climate change. Primarily intended for public health professionals and health managers, this framework would also help guide decision-makers in other health-determining sectors, such as nutrition, water and sanitation, and emergency management. International development agencies could use this framework to focus investments and country support for public health, health system strengthening and climate change adaptation. The objective of this framework is to provide guidance for health systems and public health programming to increase their capacity for protecting health in an unstable and changing climate. By implementing the 10 key components laid out in this framework, health organizations, authorities and programs will be better able to anticipate, prevent, prepare for and manage climate-related health risks. Least developed countries and countries in the process of developing the health components of National Adaptation Plans (NAPs) under the UN Framework Convention on Climate Change (UNFCCC) (4) may find this document particularly useful in their efforts to design a comprehensive response to the risks presented by short-term climate variability and long-term climate change.

The aim of this guidance is to enhance the capacity of health care facilities to protect and improve the health of their target communities in an unstable and changing climate; and to empower health care facilities to be environmentally sustainable, by optimizing the use of resources and minimizing the release of waste into the environment. This document aims to: - Guide professionals working in health care settings to understand and effectively prepare for the additional health risks posed by climate change. - Strengthen capacity to effectively conduct surveillance of climate-related diseases; and monitor, anticipate, manage and adapt to the health risks associated with climate change. - Guide health care facility officials to work with health determining sectors (including water and sanitation, energy, transportation, food, urban planning, environment; - Provide tools to assist health care facility officials assess their resilience to climate change threats etc. - Promote actions to ensure that health care facilities are constantly and increasingly strengthened and continue to be efficient and responsive to improve health, and contribute to reducing inequities and vulnerability within their local settings. The targeted audience is health care facilities and health care and public health agents.

There is serious concern about the impact of the changing climate. The WHO Regional Office for the Western Pacific has taken the initiative in addressing health issues related to climate change but further action is needed to support efforts to confront climate change in Member States and in various sectors. Health must be mainstreamed into efforts to address climate change and action must be coordinated and integrated across national boundaries and in all sectors. This report synthesizes information and approaches on climate change and health pertinent to Member States in the Western Pacific Region. It also examines efforts and initiatives by various experts and stakeholders with an in-depth look at experiences in seven Member States that reflect the diversity of the Region. Finally it offers recommendations for policy-makers.

The Working Group II contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) provides a comprehensive assessment of the scientific literature relevant to climate change impacts, adaptation and vulnerability. The report recognizes the interactions of climate, ecosystems and biodiversity, and human societies, and integrates across the natural, ecological, social and economic sciences. It emphasizes how efforts in adaptation and in reducing greenhouse gas emissions can come together in a process called climate resilient development, which enables a liveable future for biodiversity and humankind. The IPCC is the leading body for assessing climate change science. IPCC reports are produced in comprehensive, objective and transparent ways, ensuring they reflect the full range of views in the scientific literature. Novel elements include focused topical assessments, and an atlas presenting observed climate change impacts and future risks from global to regional scales.

Setting credible and ambitious decarbonization targets is a key step in implementing low carbon sustainable health systems. This document provides advice and resources to assist national and sub-national health officials in setting adequate decarbonization targets, as a supplement to the WHO Operational Framework for Building Climate Resilient and Low Carbon Health Systems. It contains a checklist of key considerations that can be used to ensure that emissions reduction targets are tangible and clearly defined, consistent with other decarbonization targets inside and outside the health sector, and function as an effective tool for driving and monitoring progress on health system decarbonization.
