Taux d’intérêt vert vs brun : comment faire ?

The document advocates for the European Central Bank (ECB) to create a 'green' versus 'brown' interest rate differential to incentivize sustainable energy and building renovations. It argues that while national subsidies and capital requirements for banks are possible, a targeted ECB mechanism—similar to the TLTROs used during the Covid-19 crisis—would be more effective and consistent with the ECB's mandate to maintain price stability by reducing fossil fuel dependency.

• High interest rates currently disadvantage sustainable energies and energy-efficient building renovations because these activities require higher initial investments compared to fossil fuels, despite having lower lifetime production costs.
• European banks are not investing enough in clean energy to meet 2030 targets; they currently invest 1.6 euros in clean energy for every euro invested in fossil fuels, whereas the International Energy Agency states 6 euros are needed. Furthermore, these banks provided over $85 billion in support for fossil fuels in 2022.
• The author proposes that the ECB implement a differentiated rate for green activities, potentially using a mechanism based on Targeted Longer Term Refinancing Operations (TLTROs) where reduced rates are granted based on green targeting rather than loan volume.
• Such a measure is argued to be compatible with the ECB's mandate of price stability, as climate crises and fossil fuel dependence cause price volatility and inflation, exemplified by the gas price surge between 2021 and 2023.
• Other potential levers, such as mandatory investment ratios for banks, increased capital requirements for fossil fuel financing, or national public subsidies, are viewed as less effective or more costly than a centralized ECB rate differential.
