Net zero emissions as a concept has recently tremendously evolved from a physical science topic to a strategical challenge of various actors. With the IPCC's call to the urgent transition towards Net Zero economy, operationalisation of climate pledges has become crucial. Financial institutions face double challenge-to decarbonize investments and drive real economy decarbonization. The credibility of net zero commitments of both financial and non-financial companies could be jeopardized and criticized if not backed by solid transition planning. Need for net zero implementation motivates a massive collective reflection. To ease, orient, shape and govern such a transformation many frameworks attempt to address the challenge. Recently emerged standards on extended disclosure as well as first guidelines and methods provide insightful content for financial sector on how to plan net zero transition. This study provides an overarching state-of-the-art review of standards, disclosure, guidelines, and assessment frameworks. Once compared and analysed these first recommendations help financial sector to get started with drafting plans. The process of decabonisation planning is integral to entity strategy and requires significant internal transformation as well as reconsideration of relations with stakeholders. The paper suggests a structure of transition plan, thus, facilitating a timely delivery of first results of robust net zero demarche by banks, insurance companies, asset owners and managers. learn more on SSRN
