Climate change, air quality and housing – future challenges to public health (CLAIH)
Contents
Scope
Purpose
The purpose of the assessment is to evaluate the health impacts and costs in Finland in the future if different housing policies are undertaken.
More specifically:
- What would be the health effects and costs in Finland in 2030 if the society preferred different household heating systems, building energy efficiency solutions and fuels for district heat production?
- How would the health effects from housing compared to health effects from other sources of PM2.5, e.g. traffic?
- What would be the optimal combination of household heating systems, building energy efficiency and fuels for district heating?
- What would be the amount of societal subsidies needed to ensure the transition to the preferred heating systems and energy efficiency in housing?
Preference of different decisions on household heating and energy efficiency is assessed from the perspective of a household. Total health impacts and societal costs of different decision options are assessed for the whole of Finland, and the optimal distribution of societal subsidies for different heating systems and energy efficiency are evaluated based on these.
