CENTRAL BANKS AND CLIMATE
Common wisdom around central bank independence (CBI) is increasingly a matter of debate. Before the Covid-19 crisis, a growing number of scholars and commentators have proposed means by which central banks can address looming climate catastrophe—either by integrating new risks into their assessments, or by promoting more active resource allocation—and argued that central bank's attention to climate risk has focused too squarely on financial stability.
In a 2018 working paper, SIMON DIKAU and ULRICH VOLZ outline how, despite the "second-best" nature of this kind of intervention, the shift is already occurring:
"Allocating financial resources toward or away from certain sectors and companies implies favoring certain segments of the economy over others and appears to be incompatible with our modern understanding of independent central banks. Nonetheless, many central banks in emerging and developing economies have resorted to these policies as viable, second-best solutions to promote sustainable development and green investment. The notion of the neutrality of monetary policy has come under intense scrutiny more recently, not least in the context of discussions about the distributional consequences of the negative interest and quantitative easing policies adopted by major central banks. It is apparent that central banks in developing and emerging economies especially, and in Asia in particular, have been at the forefront of using a broad range of instruments to address environmental risk and encourage green investment."

Brunnermeier and Jean-Pierre Landau on the applicability of central banking tools for the climate crisis: "The conventional wisdom on monetary policy is that it has no impact on long-term growth; its influence is mostly felt on a 1.5 to 2.5 years horizon. By contrast, climate change is all about the long term; effects and policies materialize and matter over several decades." Link.
