The Green Paper on Sustainable Finance in Spain, led by the Secretary General of the Treasury and International Finance, with collaboration from the Ministry for the Ecological Transition and financial supervisors, establishes the Consejo de Finanzas Sostenibles (Council for Sustainable Finance), serving as a public-private collaboration forum to address the challenges of the ecological transition and promote sustainable finance in Spain. It brings together representatives from public administrations, supervisory bodies, the financial sector, the private sector, the third sector, and independent experts. Its main work includes:
- Driving and monitoring the actions outlined in the Green Paper on Sustainable Finance.
- Developing complementary lines of work, such as analyzing challenges related to the sustainable finance regulatory framework and Creating knowledge and capacities in the field.
- Impelling new financial instruments and initiatives to facilitate the transition for companies. This includes launching a Sustainability Sandbox, creating a repository of best practices or publishing sectoral guides.
One of the working groups, led by CEOE (Confederation of Business Organizations) and the Treasury is focused on Developing Practical Guidelines: Creating specific, practical guidelines for various economic sectors to help companies, particularly SMEs, understand and implement sustainable finance criteria. The guides are being designed to help businesses align their activities and investments with the requirements of the ecological transition. A key focus is on providing clear instructions on how to apply complex European sustainable finance regulations—such as the EU Taxonomy and mandatory disclosure rules—to their specific industrial context.

A key focus is on providing clear instructions on how to apply complex European sustainable finance regulations—such as the EU Taxonomy and mandatory disclosure rules—to their specific industrial context.
In essence, the CEOE-Treasury group acts as a bridge between financial regulation and the real economy, ensuring that sustainability standards can be practically adopted by companies across all sectors to drive the shift towards a more sustainable economic model. Within this framework. The cement industry, through its national association Oficemen is leading the work by being the first industrial sector to present the guideline. This interview is framed in this context.
The cement sector is pioneering sectoral guidelines in the Council. How would you define sustainable finance in this EU context?
Sustainable finance for the cement sector must demonstrably align with the EU Taxonomy threshold of cement and the Oficemen’s Sustainable-Finance Guide. This is achieved by transforming granular decarbonization metrics (like clinker factor and alternative-fuel rate) into verifiable, investable cash-flows, with compliance and results secured through ISO 53001 / PAS 53002 management systems and third-party assurance. Sustainable finance, therefore, serves a dual purpose: ensuring a profitable, acceptable risk-adjusted return on every Euro of CAPEX while simultaneously validating environmental performance via a verifiable and compliant management system that also meets «Do-No-Significant-Harm» and Minimum Social Safeguards.
The cement industry is a “hard‑to‑abate” sector. How can sustainable finance help decarbonise it?
The strategy for financing the decarbonization of the Spanish cement industry involves blending public funding mechanisms with market instruments to reduce the Weighted Average Cost of Capital (WACC) and provide necessary price certainty for low-carbon cement production.
This approach is critical because Spanish producers require an estimated €7–9 billion for essential upgrades by 2030, including the development of CCUS (Carbon Capture, Utilization, and Storage) hubs, adoption of Alternative Fuels (AF) systems, and deployment of LC³ (Limestone Calcined Clay Cement) technology.
The financing blend includes:
- Public Support: Utilizing Innovation Fund grants to cover up to of capital expenditures (CAPEX), and employing Carbon Contracts for Difference (CfDs)—similar to Germany’s Klimaschutzverträge or the Netherlands’ SDE++—to cover operational expenditures (OPEX) over 15 years. These CfDs function by bridging the cost gap between the EU ETS price and the cost of clean production.
- Market Instruments: Integrating sustainability-linked loans and bonds.
By securing predictable revenues through CfDs, the strategy effectively lifts debt-service coverage ratios, which enables financial institutions to confidently finance these first-of-a-kind, high-CAPEX technologies.
Give examples of successful sustainable‑finance initiatives within the EU cement industry.
There is a deep and demonstrable investor demand for well-structured, KPI-linked financial instruments within the cement industry, as shown by several recent transactions from major issuers. This market interest spans different types of debt, including bonds and loans, and is universally tied to specific, measurable decarbonization targets. Examples include:
- Heidelberg Materials’ €750M Sustainability-Linked Bond (SLB) from 2023, which features a 75 basis points step-up penalty unless their net-specific emissions are by 2030.
- Holcim’s CHF 425M SLB (2022), directly linked to achieving a absolute emissions cut.
- Cementos Molins’ €300M sustainability-linked loan (2024), whose performance is tied to operational metrics like clinker factor and alternative fuel (AF) rate.
- Cemex Spain/EU’s US$1 billion perpetual Green Notes (2023), with significant funds (US$571M) allocated to tangible decarbonization projects such as using decarbonated raw material and optimizing clinker factors, all of which are subject to ISAE 3000 assurance.
- Buzzi Unicem’s green term loan, which was leveraged alongside an EU Horizon grant to fund the CLEANKER Ca-looping demonstration project, achieving a capture rate at the pilot scale.
These examples confirm that the market is willing to finance the sector’s transition, provided the instruments are credibly linked to verifiable decarbonization metrics and robust projects.
What are the biggest challenges in implementing sustainable‑finance strategies in such a capital‑intensive industry?
The sustainable transition of the cement sector faces significant hurdles, primarily characterized by high CAPEX, carbon-price volatility, technology risk, and gaps in audit-grade data. Specifically, the cost of implementing a full CCUS (Carbon Capture, Utilization, and Storage) chain is prohibitive, estimated at €140–180 per ton of and over €400 million per plant. This high investment is often undermined by the volatility of the ETS (Emissions Trading System) price, which recently dipped to around €60 in early 2024, squeezing investment margins. Although Carbon Contracts for Difference (CfDs) are a powerful tool to mitigate this price risk, they remain scarce. Furthermore, financial diligence is complicated by the lack of standardized, reliable environmental data, as only of EU kilns produce full Environmental Product Declarations (EPDs). To streamline credit processes and reduce diligence costs, initiatives like the Oficemen’s standard KPI templates and ISO 53001 verification systems are essential for providing the necessary audit-grade data.
How is Oficemen supporting its members in overcoming these obstacles?
The strategy to accelerate investment involves standardizing data, publishing a national project «deal book,» and hosting annual investor days in collaboration with major financial institutions like the (European Investment Bank), the (Instituto de Crédito Oficial), and commercial banks.
This approach is facilitated by a centralized data system where members upload quarterly (Key Performance Indicators) to a portal, ensuring alignment with reporting standards. Oficemen then aggregates this data into anonymized sector curves, which are shared with financiers to improve transparency and diligence. The «deal book» itself serves as a pipeline for finance, listing (Carbon Capture, Utilization, and Storage), , and retrofit projects that have been pre-screened for eligibility for key public funding mechanisms like the Innovation Fund or Carbon Contracts for Difference (CfDs).
What role should EU governments and regulators play in enabling sustainable finance?
The core policy message is the need to provide long-term policy visibility and consistent revenue support for industrial decarbonization through mechanisms like Carbon Contracts for Difference (CfDs), implemented alongside the full auctioning of the ETS and the rollout of the CBAM (Carbon Border Adjustment Mechanism).
CfDs are crucial because they de-risk investment revenues and significantly speed up financing for costly, first-of-a-kind projects. This strategy is already being adopted in Europe: Germany launched a €4 billion CfD tender in 2024, and the Netherlands’ SDE++ scheme is already supporting Carbon Capture and Storage (CCS) projects in Rotterdam. Furthermore, the Net-Zero Industry Act (NZIA) is set to pilot EU-level CfDs specifically for heavy industry. By combining these revenue-stabilizing CfDs with upfront Innovation Fund grants, these public policies create the financial certainty necessary for banks to invest in deep decarbonization technologies.
Are institutional investors showing more interest in the cement sector from a sustainability perspective?
Yes, the financial markets are now actively rewarding credible transition plans within the cement sector instead of excluding it outright. This shift is demonstrated by the robust investor demand for sustainable financial instruments: EU labeled issuance in the sector exceeded €4 billion in 2024. Financial institutions and rating agencies are recognizing concrete decarbonization commitments, evidenced by Sustainalytics upgrading the risk scores for industry leaders like Heidelberg Materials and Holcim after they aligned their targets with the Science Based Targets initiative (SBTi) pathway. Furthermore, the market’s enthusiasm was clear when Cemex’s Green Notes were oversubscribed more than three times, a success underpinned by independent KPMG assurance of their sustainability claims.
What long‑term financial benefits accrue to companies that embrace sustainable finance?
The financial incentives for decarbonization are driven by a combination of a lower cost of capital, preferential procurement, and premium pricing for low- products, alongside effective carbon-cost hedging. This strategic combination is crucial for making massive investments, like those in CCUS (Carbon Capture, Utilization, and Storage), viable. For instance, the strategic blending of Carbon Contracts for Difference (CfDs) and Innovation Fund grants can drastically cut the payback period for CCUS projects to less than eight years. Furthermore, low- products are commanding a premium in the market; branded products like Holcim’s ECOPact, Heidelberg’s evoZero, and Cemex’s Vertua® typically enjoy a price uplift of €10–15 per ton. This price premium provides a critical buffer that cushions producers against volatility in carbon prices, ensuring stable margins and making the sustainable business model financially attractive.
Which breakthrough technologies are most promising, and how can finance accelerate their deployment?
The future of cement decarbonization relies on key technological pathways—specifically (Carbon Capture, Utilization, and Storage) clusters, /calcined-clay blends, and -assisted electrified kilns—that are made financially viable by blending grants with operating-phase .
Significant progress is already being made: Norway’s Brevik CCS project is set to capture by 2026, while Buzzi’s Ca-looping pilot has demonstrated a capture rate at costs below . Operational shifts, such as Cemex Alicante’s use of decarbonated raw materials, are already avoiding over of clinker, funded by Green Notes. This model is sustained by smart financing: Innovation Fund grants cover the high upfront capital costs, while operating CfDs (as seen in Germany and the Netherlands) stabilize revenues to improve debt-service coverage, allowing banks to finance these massive projects. Simultaneously, KPI-linked bonds ensure that the financing is directly tied to achieving specific emission reduction milestones.
How is the cement industry addressing the social dimension of sustainable finance?
The scope of sustainable finance in the cement sector is expanding to incorporate crucial social and environmental KPIs (Key Performance Indicators), ensuring a truly just and holistic transition. This evolution moves beyond simple carbon metrics to integrate factors such as just transition, biodiversity, and safety into financing frameworks. Regulatory guidance, like PAS 53002, mandates thorough human rights due diligence. Major companies are already demonstrating this integration: Heidelberg’s evoZero includes initiatives to restore quarry habitats; Holcim links coupons on its Sustainability-Linked Bonds (SLBs) to its Lost Time Injury Frequency Rate (LTIFR); and Cemex actively tracks employee training hours and implements Water Action Plans covering of its high-stress sites. This trend ensures that financing incentivizes a transition that is not only green but also socially equitable and environmentally sound.
If you could give one message to financial institutions about the cement industry, what would it be?
The cement industry offers some of the largest and fastest-verifiable reductions per euro invested, making it a highly impactful area for climate finance. Currently, cement production accounts for approximately, but industry data (such as that from Oficemen) shows that over abatement is technically possible this decade. This massive decarbonization potential is being converted into bankable projects because policy-backed revenue support, primarily through Carbon Contracts for Difference (CfDs) and Innovation Fund grants, is now effectively de-risking revenues. When combined with -linked finance, these mechanisms ensure that the high-impact transition is financially viable and attractive to investors.
Top priorities for the next 5–10 years
The cement industry’s transition to a sustainable model is defined by five key, interrelated milestones, all targeted for the current decade:
- Establishing three Carbon Capture, Utilization, and Storage () hubs.
- Achieving a clinker factor (reducing the most -intensive component).
- Reaching an Alternative Fuels () rate (replacing fossil fuels).
- Utilizing renewable power in operations.
- Financing of CAPEX through labeled instruments (such as Green Bonds or Sustainability-Linked Loans) backed by CfDs (Carbon Contracts for Difference) and Innovation Fund grants.
These ambitious milestones are crucial, as they align with the Oficemen 2030 targets and the CEMBUREAU pathway. Successfully achieving them will cut the sector’s intensity by approximately while ensuring the industry remains competitive under the CBAM (Carbon Border Adjustment Mechanism).
How important is standardisation and metrics in sustainable finance?
Data harmonization, specifically through the use of Taxonomy KPIs, ESRS E1, and ISO 53001, is absolutely crucial as it provides a single, verifiable «source of truth» for investors.
This standardization is a powerful mechanism for market efficiency: it’s estimated that harmonized metrics can cut financial due diligence costs by , significantly curb greenwashing risks, and enable more active secondary trading of labeled debt. Industry tools, such as Oficemen templates, play a vital role by mapping specific plant-level Key Performance Indicators () directly to the required (European Sustainability Reporting Standards) tables. Furthermore, standards like PAS 53002 link corporate performance to the Sustainable Development Goals (), allowing for clearer, more meaningful cross-issuer comparison.
What about the role of digitalisation in sustainability and finance?
Digital technologies are fundamental to achieving emissions reductions and providing the audit-grade data necessary for performance-linked financing, with digital twins, optimization, and blockchain traceability leading the way.
These innovations are transforming operational efficiency and reporting credibility. For example, -assisted kiln control can yield thermal savings, directly cutting energy-related emissions and costs. Crucially, technologies like Cemex’s blockchain-ready passports, which provide -coded footprints, automate the (Measurement, Reporting, and Verification) process. This real-time, tamper-proof data is essential for triggering the margin adjustments (ratchets) built into Sustainability-Linked Loans (). As the (European Sustainability Reporting Standards) moves towards machine-readable formats, adopting robust digital systems is becoming decisive for maintaining investor trust and streamlining financing.
