Since the Paris Agreement, interest in decarbonization and sustainable finance has grown rapidly. Within the prevalent derisking regime, investment for decarbonization must come predominantly from the private sector. However, growth in ‘sustainable finance’ assets is not necessarily causing more sustainability-advancing productive investment to drive the green transition. We thus argue that sustainable finance is not exclusively about investing or providing finance, but crucially also about changing corporate practices toward greater sustainability. To shed light on how private financial actors can influence sustainability in a derisking context and to facilitate this broader research perspective on sustainable finance, we introduce the conceptual framework of ‘channels of influence’. These channels are different strategies and mechanisms used by private actors that influence the behavior of financial and non-financial corporations to increase financial flows to sustainable productive investments. We identify ten channels of influence concerning sustainable finance: (1) initial financing; (2) refinancing; (3) (re)insurance; (4) ratings; (5) climate-litigation; (6) company engagement; (7) divestment; (8) reputation; (9) coalition-building; and (10) standard-setting. These are grouped according to the specificity and breadth of their sustainability impact. Using these channels enables private actors to advance sustainability within the status quo of state-market relations and regulation.
