It is an honour to be speaking to you today as part of your series of workshops. As Maurice Allais once said, “what could be a better way of preparing for the aftermath of the war than to try to find a solution to the fundamental problem of any economy, namely how to promote the greatest feasible economic efficiency”.

In many ways, his vision was borne out. Prioritising efficiency, both in our internal economic affairs, such as developing the single European market, and in our external trade, led to a period of unprecedented sustained economic growth. And as economies advanced along a path of steadily increasing potential output, central banks like the ECB could focus first and foremost on stabilising inflation by managing demand, without having to worry too much about structural changes in the economy. But Maurice Allais also predicted that widespread global integration without proper governance could “only create instability everywhere”.

And this prediction is now, regrettably, also proving to be correct. Open trade has led to increasing tensions between major powers – although notably not within the EU, where we have had a suitable governance system in place. And as a result, multilateral trade is becoming more fragmented: the number of new global trade restrictions has been rising steadily, from about 650 new restrictions in 2017 to more than 3,000 in 2023. At the same time, the environmental costs of rapid global economic integration – coupled with the undervaluation of ecosystem services – are now having to be paid.

The supply of the nature-related services that underpin global growth, such as timber, minerals and carbon storage, is diminishing. Six of the nine “planetary boundaries” – Earth system processes, including climate change and biodiversity, which maintain the planet’s stability – have been breached. These developments reinforce each other, as increasing animosity reduces the political will to work together on climate issues. And rising trade barriers impede the flow of renewable technologies that are crucial to preventing further climate degradation.

As central bankers, we are now facing a fundamentally different environment: one characterised by more instability, more volatility and more uncertainty about the very structure of the economy. I have argued previously that this new world requires us to rethink our policy frameworks.

Today, I would like to explain why, as we develop strategies to manage this environment, we need to pay particular attention to climate and nature-related risks owing to the unique impacts they have. And I will also explain how the ECB is responding to them. The world never stands still, and central banks are constantly facing new shocks, new risks and changes in the economic environment – be it reversals in government policy, tensions in the financial sector or disruptions in global trade. In most cases, we simply have to take the environment as given and adjust our policy accordingly.

But there are four factors which make climate and nature-related risks a unique challenge for central banks – a challenge that calls for a different type of response. First, they are a new type of systemic risk. Unlike rare tail events known as “black swans”, climate change represents is inevitable because it is doomed to happen if not addressed by appropriate policies.

These risks also extend globally. If we fail to stop the rise in average temperatures, extreme climate events will become inevitable. Among 380 climate scientists from the Intergovernmental Panel on Climate Change, 77% believe humanity is headed for at least 2.5°C of global heating, well beyond the Paris Agreement goal of 1.5°C.

The second factor is the irreversibility of their impacts. If we do not reverse the course of climate change and environmental degradation, we will reach points of no return. Some ecosystems are subject to tipping points which, if reached, may change the climate so much that it is impossible – or extremely difficult and costly – to return the environment to its original state. For example, the Amazon rainforest and tropical peatlands currently store around 220 gigatonnes of carbon, equivalent to 20 years of global CO2 emissions. If these were destabilised, it would become virtually impossible to stay below 1.5°C of global heating.

Third, the impacts of climate and nature-related risks will spread throughout the economy, affecting central banks’ tasks.

The recent energy crisis, although unrelated to the green transition, illustrates how volatile energy prices and shifts in energy markets can significantly influence inflation dynamics. The increase in prices of energy and energy-sensitive goods and services contributed around 6 percentage points to euro area inflation at its peak in October 2022.

Furthermore, climate and nature-related risks create financial risks on the balance sheets of financial institutions. These risks can lead to losses or higher funding costs, reducing the flow of credit to the real economy. This can also affect the transmission of central bank policies to the financing conditions of households and firms. In the euro area, banks are exposed to climate-related risks, with high-emitting sectors over-represented in their corporate loan portfolios, accounting for over 70% of corporate lending. These risks also extend to our own holdings of corporate bonds.

Finally, these risks are also unique in that, unlike for instance geopolitical risks, central banks can contribute towards mitigating them. There is broad political consensus on the need to tackle the causes of climate risks. And while governments are in the lead and have the most powerful tools, we can also play our part, within our mandate, in preparing the economy for the future.

So, what is the ECB doing?

First of all, we are maintaining price stability, which is essential for the transition to a low-carbon and circular economy. The green transition requires substantial investment, and a stable inflation outlook gives firms greater visibility on investment costs, which is particularly important for green projects given their long-term planning horizons. Moreover, price stability supports the relative price signals from policies such as carbon pricing, improving their efficiency.

But beyond creating the right conditions for investment, we are committed to playing our part to address climate change, within our mandate. Our approach can be summarised with three key words: analysing, advising and acting. The basis of contributing to addressing climate change – within the scope of our tasks – is our analysis of how it affects the economy, the financial system and our own activities.

In recent years, we have made significant strides in understanding climate risks. Our findings show that delaying the green transition may result in increased long-term costs. Furthermore, climate change may pose systemic risks to financial stability, and the degradation of nature may pose additional risks in this area.

But there is still more ground to cover. That is why we have announced our plan for 2024-2025, which builds on existing work and explores new frontiers. It calls for robust analysis, and we have identified three core areas for this analysis. First, we are delving deeper into the green transition’s impact on labour markets, economic shocks and investment needs. For example, ECB research shows that the 2022 heatwave in Europe increased food price inflation in the euro area by around 0.7 percentage points.
