MAIRE Secures €185 Million Sustainability-Linked Loan

Italian engineering firm links €185 million borrowing to carbon reduction targets

MAIRE, an Italian engineering and construction company focused on energy transition projects, has raised €185 million through a sustainability-linked loan. The financing ties borrowing costs directly to the company’s ability to cut emissions and engage suppliers in climate action by the end of 2028.

The deal, completed on 20 April 2026, represents the third time MAIRE has used environmental performance metrics to secure funding. It follows a sustainability-linked bond issued in November 2025 and an earlier €62.5 million loan with similar terms.

For UK businesses watching developments in sustainable finance, this transaction illustrates how companies can access capital markets while committing to measurable environmental targets. However, it also highlights the financial penalties that come with missing those goals.

The loan structure and performance conditions

The €185 million loan consists of two tranches. A three-year portion carries a margin of 1.50 percentage points above the six-month Euribor rate. Meanwhile, a five-year tranche has a margin of 1.70 percentage points.

MAIRE must achieve two specific targets by 31 December 2028. First, the company needs to reduce its Scope 1 and Scope 2 greenhouse gas emissions by 28 per cent compared to 2024 levels. Second, at least 20 per cent of its suppliers, measured by Scope 3 Category 1 emissions from purchased goods and services, must adopt science-based targets.

Missing either target triggers a margin step-up, increasing borrowing costs. This penalty mechanism is central to sustainability-linked finance, creating a direct financial incentive for environmental performance.

The loan was placed with banks from Europe, Asia, and the Middle East. Arrangers included BNP Paribas, BPER CIB, Commerzbank, Crédit Agricole CIB as sustainability coordinator, Intesa Sanpaolo IMI CIB, and UniCredit as paying agent. Cassa Depositi e Prestiti provided additional support.

MAIRE has the option to increase the loan to €300 million by the end of July 2026, suggesting potential expansion of its transition-related activities.

MAIRE’s approach to sustainable financing

MAIRE operates primarily through its Nextchem division, which develops decarbonization technologies for energy-intensive industries. The company adopted its Sustainability-Linked Financing Framework in October 2025, setting out how it would link capital raising to environmental performance.

This framework earned alignment with Sustainability-Linked Bond and Loan Principles, as confirmed by Sustainalytics in a 2023 second-party opinion. The validation provides external verification that MAIRE’s targets are material, measurable, and ambitious relative to its operations.

According to MAIRE’s chief financial officer, Mariano Avanzi, the loan enables the company to optimize its financial structure. He noted that continued investor interest reflects confidence in both MAIRE’s financial stability and its commitment to sustainable growth.

The company plans to use the proceeds for general corporate purposes, primarily to repay existing debt facilities early. This refinancing reduces average borrowing costs while extending debt maturities. An earlier Schuldschein refinancing reportedly saved MAIRE over 110 basis points in interest.

What Scope 1, 2, and 3 emissions mean in practice

Understanding the emissions categories in MAIRE’s targets matters for any business considering similar commitments. Scope 1 covers direct emissions from owned or controlled sources, such as fuel combustion in company vehicles or on-site boilers. Scope 2 includes indirect emissions from purchased electricity, heat, or steam.

Scope 3 encompasses all other indirect emissions in a company’s value chain. Category 1 specifically refers to emissions from purchased goods and services. For an engineering firm like MAIRE, this includes materials, components, and subcontracted services.

The supplier target is particularly significant. MAIRE cannot simply reduce its own operational emissions to meet the loan conditions. Instead, it must engage suppliers representing at least 20 per cent of Category 1 emissions and persuade them to set science-based targets.

Science-based targets align with the level of decarbonization required to keep global temperature rise below 1.5 or 2 degrees Celsius. They require companies to commit to specific percentage reductions over defined timeframes, validated by the Science Based Targets initiative.

This requirement pushes carbon responsibility down the supply chain. Consequently, suppliers to large contractors may face increasing pressure to measure and reduce their emissions, even if they have not previously considered such commitments.

Implications for UK engineering and construction businesses

Several aspects of MAIRE’s financing approach carry relevance for UK firms in similar sectors. First, sustainability-linked debt is becoming more accessible across European markets. Businesses no longer need to issue green bonds exclusively for renewable energy projects. Instead, they can tie general corporate borrowing to performance metrics.

Second, the deal demonstrates that lenders now expect companies to address supply chain emissions, not just direct operations. For construction and engineering firms, this means procurement decisions carry environmental consequences that affect capital costs.

Third, the margin step-up mechanism creates real financial risk. If MAIRE misses its 2028 targets, borrowing costs increase immediately. This structure differs from voluntary sustainability reporting, where missing targets might damage reputation but not trigger contractual penalties.

UK businesses in construction, manufacturing, and engineering sectors should note that this approach to financing may influence tender requirements. Public sector buyers already evaluate carbon reduction plans through mechanisms like PPN 06/21. Private sector clients may increasingly favor suppliers with demonstrable emissions targets backed by financial commitments.

Additionally, the supplier engagement requirement creates potential challenges. Businesses may need to assess supplier emissions data quality, provide technical support for target setting, and potentially adjust procurement decisions based on supplier climate commitments. These activities require resources and expertise that many SMEs currently lack.

The rise of performance-linked sustainable finance

Sustainability-linked loans and bonds differ from green finance instruments in several important ways. Green bonds must allocate proceeds to specific environmental projects, such as renewable energy installations or energy efficiency improvements. Issuers must track and report how they spend the money.

In contrast, sustainability-linked instruments allow general corporate use of proceeds. Instead, the borrower commits to achieving specific sustainability performance targets. The environmental benefit comes from the borrower’s overall performance improvement, not from how it spends the borrowed money.

This structure suits companies like MAIRE that need flexible capital for general operations while demonstrating climate commitment. It also appeals to lenders seeking to support transition-focused businesses without restricting fund usage.

However, the model depends entirely on robust target setting and verification. Weak targets or inadequate measurement allow companies to benefit from lower borrowing costs without meaningful environmental progress. Therefore, external validation by organizations like Sustainalytics has become standard practice.

The market for sustainability-linked debt has grown significantly since 2019. European companies have led adoption, particularly in sectors with high emissions profiles seeking to finance transition activities. UK businesses considering similar approaches should prepare for detailed due diligence on baseline emissions, target ambition, and measurement methodologies.

Essential details about MAIRE’s sustainability loan

• MAIRE raised €185 million on 20 April 2026 through a sustainability-linked Schuldschein loan with two tranches at 1.50 per cent and 1.70 per cent margins over Euribor for three-year and five-year terms respectively.
• The loan requires MAIRE to reduce Scope 1 and 2 emissions by 28 per cent by 31 December 2028 compared to 2024 levels, with margin increases if targets are missed.
• At least 20 per cent of suppliers by Scope 3 Category 1 emissions must adopt science-based targets by the same deadline, pushing carbon accountability into the supply chain.
• This marks MAIRE’s third sustainability-linked financing following a bond in November 2025 and an earlier €62.5 million loan, forming part of a broader refinancing strategy.
• The company’s Sustainability-Linked Financing Framework, adopted in October 2025, received validation from Sustainalytics confirming alignment with international sustainable finance principles.
• Proceeds will primarily refinance existing debt at lower average costs, with an option to increase the facility to €300 million by end of July 2026.
• Strong demand from European, Asian, and Middle Eastern banks indicates growing investor appetite for transition-linked debt in engineering and construction sectors.

What this means for businesses considering similar commitments

MAIRE’s loan structure offers a template for companies wanting to demonstrate environmental commitment while accessing competitive finance. Nevertheless, several considerations matter before pursuing this approach.

Baseline data quality is fundamental. Companies need accurate Scope 1 and 2 emissions measurements covering all relevant activities. For Scope 3 supplier targets, businesses must collect data from multiple organizations with varying measurement capabilities. This often proves more challenging than measuring direct emissions.

Target ambition must be defensible. Lenders and validators assess whether proposed reductions align with science-based pathways. Targets that are too easy invite accusations of greenwashing. Targets that are unrealistically ambitious create financial risk through margin step-ups.

Operational control over outcomes is critical. Companies retain full control over their Scope 1 and 2 emissions through investment decisions, operational changes, and procurement choices. However, supplier engagement targets depend partly on external parties’ willingness to participate. This introduces execution risk that companies cannot fully control.

Resource requirements should not be underestimated. Measuring emissions, engaging suppliers, implementing reduction projects, and reporting progress all require dedicated personnel or external support. For businesses considering carbon reporting programs aligned with net zero commitments, these capabilities need development well before linking them to borrowing costs.

The penalty mechanism creates board-level accountability. Missing targets does not simply require disclosure in a sustainability report. Instead, it immediately increases finance costs, affecting profitability. Therefore, sustainability commitments embedded in loan terms become strategic business priorities, not voluntary initiatives.

Broader context for supply chain emissions requirements

MAIRE’s supplier target reflects a wider trend in corporate climate action. Scope 3 emissions typically represent the largest portion of a company’s carbon footprint, particularly for businesses that purchase significant materials or services.

For engineering and construction firms, purchased goods and services often generate several times more emissions than direct operations. Steel, cement, chemicals, and manufactured components carry substantial embedded carbon. Consequently, meaningful emissions reductions require supply chain engagement.

However, supplier emissions data remains inconsistent across industries. Many smaller suppliers lack the systems to measure and report their carbon footprint accurately. This creates challenges for companies trying to assess their Scope 3 baseline or track supplier progress toward targets.

Some businesses address this through supplier development programs, providing tools and training to improve measurement capabilities. Others use industry average emissions factors as proxies until primary data becomes available. Both approaches require significant effort and may not satisfy validator requirements for sustainability-linked finance.

UK businesses should anticipate increasing client demands for supply chain emissions data. Public sector frameworks already require this information for larger contracts. Private sector clients, particularly those with their own sustainability-linked finance commitments, will likely extend similar requirements to their suppliers.

Organizations needing to develop compliance capabilities for carbon reporting and supply chain assessment should begin building measurement systems now, rather than waiting for client mandates.

Financial benefits and risks of sustainability-linked debt

The primary advantage of sustainability-linked finance is potentially lower borrowing costs. Lenders often offer margin reductions for borrowers who meet environmental targets, creating a direct financial return on climate investment.

For MAIRE, refinancing existing debt at lower rates while extending maturities improves cash flow and financial flexibility. The company reportedly saved over 110 basis points through an earlier refinancing, representing substantial interest savings over a multi-year term.

Additionally, sustainability-linked instruments can improve access to capital. A growing number of investment funds have mandates to deploy capital only to borrowers with credible environmental commitments. Consequently, companies with validated sustainability frameworks may access larger pools of capital than competitors without such commitments.

Nevertheless, the margin step-up risk is real. If MAIRE misses either target by 31 December 2028, borrowing costs increase immediately. Over a five-year term, the additional interest expense could be substantial, potentially exceeding the cost of emissions reduction investments.

This risk profile suits companies with high confidence in their ability to deliver environmental performance. It may not suit businesses with limited control over key variables, inadequate measurement systems, or insufficient resources to implement reduction projects.

Furthermore, the reputational risk of missing targets should not be overlooked. Public disclosure requirements mean that failure to achieve sustainability-linked debt targets becomes visible to investors, clients, and competitors. This could affect future financing terms and commercial relationships.
