Climate change, particularly more prevalent heat waves, are causing health risks predominantly among aging people. In social and health care there is a need to adapt to heat-related health risks and other climate change induced harms so that health security and functionality of services can be maintained even when extreme weather phenomena occur. In addition, social and health care is a major greenhouse gas emitter whose emissions account for 6.5% of Finland’s total carbon footprint. As European Union and Finland are aiming at carbon neutrality, emissions in social and health care need to be reduced. Isohoito -project will collect and distribute good practises on climate change adaptation and mitigation in health and social sector, and investigate information needs for further guidance. These actions can strengthen adaptation to weather and climate-related risks and respond to challenges of green transition in social and health care sector. Most prior projects have focussed either on climate change adaptation or mitigation, but this project considers them simultaneously, since these issues often are intertwined. The project aims to: 1) Increase awareness regarding climate change adaptation and mitigation in social and health care; 2) strengthen climate resilience and climate change mitigation by bringing these issues to strategic planning of the wellbeing services counties; 3) prevent heat-related morbidity and mortality risks among vulnerable population groups; and 4) develop monitoring of national climate change adaptation plans. These aims are reached by the following actions: 1) collection of existing climate-related strategies and implementation plans from the wellbeing services counties and forming a summarization of these to be used by those counties with no such strategies and plans; 2) collection of good practices on adaptation to heat-related risks and climate change mitigation as well as information about obstacles and contributors related to their implementation in health and social care; 3) collection of information and guidance needs regarding heat-related risks and climate change mitigation in health and social care; 4) measurements for information basis to form procedures to prevent heat-related risks and to re-assess the decree on safe and healthy indoor temperatures during summer time; 5) development of monitoring framework for National Climate Change Adaptation Plan 2030 and that for the climate change adaptation plan for health and social sector. Employees of the social and health care are invited to participate in the project via interviews and workshops. The measurements of indoor temperatures will take place in elderly care since this is one of the most vulnerable population groups regarding health effects of heat. Good practises and other information will be distributed and communicated through various channels, including responsibility forum of the wellbeing services counties and Innokylä platform.
