@riccardobaioni.bsky.social, Nicolás Águila, Janina Urban, @paulahaufe.bsky.social, @simonschairer.bsky.social & @jwullweber.bsky.social discuss how the European Commission attempted to reinvigorate the stalled Capital Markets Union project by reframing it as a vehicle for green investments 👇

Disclaimer: Many activities necessary for the green transition will never be bankable, and therefore will never be attractive for financial investors. As a result, the state should directly provide the necessary financing.
You can find our full policy report here: www.uni-wh.de/en/your-camp...

The figure illustrates how financial policies should function: Green investments require derisking policies and better financing conditions to become bankable. For greenhouse gas-emitting investments, policies should increase risk and decrease returns in order to reduce their bankability.

Figure from our #policy #report: 1. The main barrier to #financing the necessary activities for the sustainable transition is their lack of #bankability
2. High GHG-emitting activities remain #bankable and thus continue to attract financing from banks and shadow banks

#4 This taxonomy forms the basis for the projects’ policy recommendations that can increase the bankability of not-yet bankable firms and projects, decrease the bankability of high-GHG emitting ones, and expand financing for never bankable activities. @wbgu.bsky.social @ioew.bsky.social

#3 In other words, many green firms and projects are considered as ‘non-bankable’. Based on our analysis, we propose a classification that considers two criteria: 1) Is the investment green or does it generate high GHG emissions? 2) Is it bankable, not yet bankable, or never bankable?

#2 We show that the problem is not the lack of capital, but the lack of bankable green projects. Increases in green lending and investments by banks and other financial institutions remain negligible because green investments fail to meet the desired risk-return profiles of investors.

Our #policy #paper has just been published: "Financing the #green #transition: Increasing #bankability, phasing out carbon investments and funding 'never bankable' activities". We ask: Why does a large green financing gap persist? What policies do we need to change it: www.uni-wh.de/en/your-camp...

We had an intense week at the German Advisory Council on Global Change @wbgu.bsky.social. In light of the challenges facing the German society and societies all over the world, how can the WBGU support policymakers in addressing global environmental change? Stay tuned for our answers!

A great paper!

Our second [tra:ce] working paper, which addresses the challenges of financing green investments, is out: "The green banking gap: how bankability, business models, and regulations challenge banks' decarbonisation". Join our public paper launch on Monday, 26 May, 11h (CET)!

(1) loan securitization, (2) emissions risk transfers, (3) bond financing, (4) carbon asset partitioning, (5) offshore corporate wealth chains, (6) private credit, and (7) proved developed producing reserves securitization.

Drawing on qualitative expert interviews and financial market data, the paper explains how the offshore-shadow-banking nexus hampers the green transition by introducing the concept of ‘shadow carbon financing’, which can operate through the following seven channels:

These blind spots seriously undermine regulatory efficacy because offshore finance enables the obfuscation of financial flows, while shadow banking facilitates alternative financing to high carbon-emitting firms.

Recent years saw regulatory efforts to steer the financial system towards financing the transition to a net-zero economy and phase out carbon financing. However, EU regulation has left the nexus of offshore finance and the shadow banking system untouched.

Out of the light, into the dark: how ‘shadow carbon financing’ hampers the green transition and increases climate-related systemic risk

How can we finance a globally just sustainable transformation? In this piece with @naguila.bsky.social, @jwullweber.bsky.social we explore the need to reform the international monetary system for that purpose. Big thank you to @isrfoundation.bsky.social for publishing it and amazing editorial work👇
