Climate change and nature degradation should be treated as economic and financial risks rather than as issues outside the remit of central banks, Frank Elderson, an Executive Board member of the European Central Bank, said in a keynote address in Manila.
Elderson’s argument placed physical disruption, inflation pressures, energy dependence and industrial competitiveness in the same frame. Drought, floods, extreme heat and ecosystem stress can impair production and infrastructure directly, he said, while their effects can also spread through food, electricity, transport and finance. For Europe, the implication is that resilience is not simply a defensive environmental policy but a condition for sustained economic performance.
The speech, delivered at the Green Swan 2026 Conference on 19 October, did not announce a new ECB policy measure, supervisory requirement or forecast. It instead set out Elderson’s view of why climate and nature considerations belong in economic analysis and why adaptation and emissions reduction should be pursued together. He also argued that a transition away from imported fossil fuels can reinforce energy security and competitiveness if it is managed effectively.
Physical shocks can leave longer economic scars
Elderson described climate and nature risks as systemic because individual events can accumulate, overlap and amplify one another across the economy. Looking at a drought, flood or wildfire in isolation may understate the wider exposure, he argued. The central question for policymakers and financial authorities is how repeated shocks affect output, prices, investment, population movements and the resilience of the financial system over time.
His examples were concrete. Extreme heat can cut labour productivity. Drought can constrain agriculture, industry and transport. Flooding can damage infrastructure and interrupt production. In the ECB official’s account, the economic effects need not disappear once the immediate event has passed: major shocks can delay investment, prompt relocation and leave output below its previous path for years.
That distinction matters for an institution whose core responsibilities include price stability and, through banking supervision, the safety and soundness of lenders. A weather event that temporarily reduces output is one economic problem. A succession of disruptions that changes productivity, investment choices and the costs faced by households and firms is another. Elderson said central-bank models and forecasting approaches must reflect how climate change and nature degradation can alter the structure of the economy.
Prices form a second transmission channel in his argument. High temperatures and low water levels can disrupt energy systems and affect wholesale electricity prices, while extreme weather can influence food prices. The result is an inflation question as well as a growth question. Elderson did not claim that every climate event produces a broad macroeconomic crisis. Rather, he said a more frequent and severe pattern of hazards is increasingly becoming a structural factor in economic and financial outcomes.
The cross-border nature of the exposure adds to the difficulty. Food-price pressures, supply-chain disruption and migration pressures can move across national boundaries, he said. Nature-related vulnerabilities can do so through comparable channels. The relevant policy task is therefore not to claim certainty about the timing or magnitude of every hazard, but to improve data and analysis, identify vulnerabilities and respond in proportion to the risks identified.
Water scarcity is presented as a material euro-area exposure
Among the numerical estimates cited in the speech, Elderson pointed to recent ECB research suggesting that severe water scarcity alone could put as much as 24% of euro-area economic output at risk. This is an estimate of output exposed to a specific risk, not a projection of an immediate loss, nor an assessment that such a share of output will necessarily be lost. The speech also referred more broadly to exposure of economic activity and bank lending to flooding.
The estimate illustrates why Elderson treats nature as an economic input rather than a peripheral concern. Water affects households, farming, manufacturing, transport and energy production. Forests, soils, rivers, wetlands and oceans also provide functions on which day-to-day activity depends, he said. When such systems come under pressure, the impact is not confined to a single industry or locality.
For banks and supervisors, the practical challenge is tracing exposures across borrowers, assets, supply chains and regions. A manufacturer may face operational disruption, a transport operator may face low water levels, and a lender may face the consequences through multiple clients at once. The speech does not quantify those potential effects or set out a new methodology for measuring them. It does, however, make the case that the risks merit a place in macroeconomic and financial-stability work because they can affect productivity, growth, inflation and financial resilience.
Elderson also linked the issue to international cooperation. He described exchanges among central bankers, supervisors, policymakers and researchers as valuable in a period of geopolitical fragmentation. The reasoning is straightforward: hazards and economic spillovers do not respect borders, while institutions attempting to assess them confront common problems of incomplete information, uncertain pathways and changing underlying conditions.
Adaptation and mitigation serve different economic purposes
A central distinction in the address was between adaptation, which seeks to limit the consequences of climate and nature pressures, and mitigation, which addresses their causes. Elderson said both are required. Past emissions have already produced changes that cannot be reversed immediately, meaning that households, companies, public authorities and financial institutions still need to prepare for effects already in train. At the same time, without mitigation, the scale and cost of required adaptation would grow.
His adaptation agenda included early-warning systems, infrastructure able to withstand extreme weather, water management, flood prevention, energy-efficient cooling and reduced water leakage. He also cited the need for more resilient energy systems, cities, transport networks and production arrangements. These are not presented as optional environmental upgrades. In his formulation, they are measures intended to keep economies functioning under more difficult climatic conditions.
The speech acknowledged that European regions and cities are already investing in resilience, with initiatives at European Union level intended to support preparation for water scarcity, floods and wildfires. Its emphasis was on acceleration and scale rather than on a named new programme. For finance, that framing points to a broad set of potential investment needs, but the address did not offer a cost total, timetable, financing plan or allocation between public and private sectors.
Mitigation, meanwhile, is cast as a way of containing future adaptation burdens. Elderson argued that the two strands reinforce one another: effective mitigation lowers future physical risks and costs, while effective adaptation can help economies stay resilient during the transition. He rejected the notion of a single remedy, presenting instead a direction in which policy, infrastructure, corporate planning and finance would need to work together.
Energy dependence is central to the competitiveness argument
Elderson’s most explicit economic-policy claim was that resilience, energy security, competitiveness and the green transition should not be viewed as competing aims. Companies cannot remain competitive, he argued, if their operations become more exposed to climate and nature shocks. Europe’s dependence on imported energy, much of it fossil-fuel based, was described as a source of vulnerability to geopolitical shocks and uncertainty for households and businesses.
In that context, he said renewable generation and electrification can strengthen resilience by reducing dependence on imported fossil fuels. Electricity accounts for roughly one quarter of final energy consumption in Europe, according to the speech, leaving scope to electrify transport, buildings and industry. That figure describes the starting point cited by Elderson; it does not establish how quickly electrification will proceed or what obstacles particular sectors may face.
The ECB official said renewable technologies have become more cost-competitive and can in some cases cost less than new fossil-fuel alternatives. He also attributed to the International Energy Agency an estimate that a significant share of residential heating, road transport and industrial heat could already be electrified cost-effectively. These are assessments cited in a policy speech, not investment recommendations or guarantees about the cost of any individual project.
His broader message was that the question is no longer whether economic systems will move along a green-energy transition, but how countries and companies position themselves in it. In that view, ownership and financing of future assets, along with the risk that existing assets lose value, are consequential questions for competitiveness and financial stability. The speech did not identify particular companies, securities or sectors as beneficiaries or casualties, and it offered no guidance to investors.
The speech sets a direction, not a policy decision
The immediate significance of Elderson’s remarks lies in the ECB’s continuing effort to describe climate and nature risks as relevant to its established responsibilities, rather than as a separate policy agenda. The address connects physical risks to inflation and output, and it connects the transition to energy security and economic resilience. It stops short of setting new rules, changing interest-rate policy or publishing a fresh supervisory exercise.
Important questions remain outside the speech. It does not specify how the cited risks will be incorporated into future ECB forecasts, how exposures should be compared across firms or banks, or how the costs of adaptation will be financed. Nor does it resolve trade-offs that can arise among affordability, infrastructure build-out, industrial strategy and environmental aims. Those are policy and commercial questions that require evidence beyond the address itself.
The report is based on an ECB page describing Elderson’s keynote and has not been independently corroborated. Its claims should therefore be read as the position and analysis set out by the ECB official, including the research and external estimates he cited, rather than as independently verified findings in this report.
