Welfare policy involves the discussion on public and private responsibilities and choices in public spending. The Finnish government's decision to turn Finland into a carbon neutral welfare society by 2035 is interpreted as a possible sustainability transition. The government launched a social security reform at the same time as the carbon neutrality target was announced. It was assumed that one of the major reforms would be utilised to achieve the carbon neutrality target. The research material consists of administrative, policy and political documents. The chosen documents describe how the issues are presented in policymaking. The qualitative analyses focused on the frames. It was examined how the current problems of the system were framed because the frames guide the possible solutions. According to our analysis, the Finnish government showed strong political will for sustainability transition. However, one of its major reforms was not utilised to create policies to support the shift towards a carbon neutral welfare society. The political will did not convert into action on the social security reform. The main reason seems to be related to the strongly guiding legislative frame in the reform. The legislative frame impacted on the utilised knowledge, which focused solely on the system level of social security. It could have been useful to utilise research knowledge about large‐scale reforms and how to formulate them cross‐sectionally. 收起
