Having in mind that European Union (EU) has committed to Paris agreement goal of keeping temperature at less than 1.5 ℃ above preindustrial level, has made decision to reach climate neutrality reached by 2050, and have greenhouse gas (GHG) emissions reduced by 50–55% by 2030, the issue of avoiding stranded costs should be immediately considered. Since natural gas boilers have life of 20+ years, and infrastructure even more, it is time to start preparing the exit strategy, in order to avoid stranded costs being loaded on consumers and market players.
