Belgian banks lag Paris climate alignment, report warns

Belgium’s financial sector is confronting a credibility challenge after a new Climact report for the federal environment service revealed that fewer than 40% of Belgian banks have climate strategies aligned with the Paris Agreement. Published on 12 November 2025, the findings underscore a widening gap between national climate ambitions and the practical integration of transition risk, financed emissions and climate-stress testing inside bank decision-making frameworks. While Belgium positions itself as a supporter of EU-wide climate leadership, its banking system’s incomplete alignment reveals structural vulnerabilities that may influence credit allocation, capital requirements and long-term competitiveness.

The mechanism behind the alignment shortfall is threefold. First, many Belgian banks still maintain significant loan and investment exposures to carbon-intensive sectors — ranging from chemicals and metals to legacy manufacturing and transport systems. Financing portfolios remain insufficiently shifted toward renewable energy, green infrastructure or low-carbon industrial technologies. Second, most banks lack granular, sector-level decarbonisation pathways consistent with a 1.5°C or even 2°C warming trajectory. Without clear emissions baselines, scenario tools or counterparty-transition scoring, internal climate-risk assessments remain descriptive rather than quantitative. Third, smaller banks confront resource constraints in integrating climate models, ESG data systems and EU Taxonomy-compliance frameworks, making transition planning operationally challenging.

Macro-financial implications extend beyond environmental concerns. As EU regulations tighten—particularly through the Corporate Sustainability Reporting Directive (CSRD), European Banking Authority (EBA) stress-testing and forthcoming climate capital charges—banks misaligned with Paris goals face higher regulatory costs, potential capital add-ons and reputational risk. Lending portfolios weighted toward high-emission sectors risk value impairment if carbon pricing increases or EU state-aid rules accelerate industrial decarbonisation. Belgian banks with weaker alignment may also become less attractive to institutional investors prioritising Article-8/9 EU-SFDR strategies.

The Belgian economy is structurally exposed to transition risk given its energy-intensive industrial clusters, including petrochemicals in Antwerp, metallurgy, and transport-logistics hubs. Banks’ inability to shift capital allocation could slow industrial decarbonisation, complicating Belgium’s ability to hit its 2030 climate targets. Moreover, fragmented climate-risk integration creates uneven incentives for companies trying to finance green upgrades, resulting in competitive distortions between corporates with access to sustainability-linked financing and those dependent on traditional credit.

Market reactions to the report were muted but directionally important. Climate-focused investors highlighted persistent ESG laggards in Belgian portfolios, and several funds indicated that banks with slower transition plans may face exclusion from sustainable indexes. Bond-market pricing suggests that lenders with robust green-financing pipelines trade at tighter spreads relative to peers slow to adopt climate frameworks.

Looking ahead, key indicators include: (1) banks’ financed-emissions disclosure under CSRD; (2) alignment of credit portfolios with EU Taxonomy thresholds; (3) uptake of sustainability-linked loans for SMEs; and (4) EBA climate stress-test outcomes in 2026. If Belgian banks accelerate Paris-aligned lending trajectories and adopt sectoral decarbonisation pathways, they can reduce regulatory and balance-sheet risk while capturing green-finance demand. Failure to act, however, may lead to punitive capital charges, investor reallocation and erosion of cross-border competitiveness.

Belgium’s climate-finance gap is therefore more than a compliance issue—it is a structural economic risk. The next phase of alignment will determine whether the financial sector becomes an enabler of Belgium’s transition goals or a bottleneck constraining industrial transformation.
