The european investment bank’s ‘quantum leap’ to become the world’s first international climate bank

peer reviewedIn November 2019, the European Investment Bank (EIB) announced its ‘metamorphosis’ into a ‘Climate Bank.’ Associated with the EU’s Green Deal, presented a month later, the EIB claimed to be the first international climate bank and a front runner in the EU’s priority climate agenda. The EIB is mandated through the treaties to support EU policymakers. However, with its ‘makeover,’ the EIB also announced the launch of a new climate strategy and energy lending policy, ending fossil fuel financing after 2021. It is thus valuable to examine the question of whether the EIB has developed into a policymaker, and if so, how this can be best understood. In exploring this question, this article follows a principal‐agent approach, attempting to discern the rational interests behind organisational rhetoric and posits that the EIB’s claimed transforma-tion hints at a type of policymaking activism, exploiting a policy window to serve the EIB’s rational interests in a strained political and market contest. This represents a paradigm shift in the EIB’s institutional behaviour and rhetoric within the EU governance constellation and is, in fact, in this sense a ‘quantum leap’ as suggested by the EIB. However, it remains to be seen if the bank’s metrics will prove a bold departure from their current activity or simply another adaptation to a policy field of intense interest to the EU, as has occurred on several occasions in the past
