Carbon accounting software for companies in Spain
Spanish companies face a fast-moving stack of obligations — Royal Decree 214/2025's mandatory carbon-footprint and reduction-plan rules, the legacy non-financial reporting law (Ley 11/2018), and the EU CSRD as it is finally transposed — and they need a greenhouse-gas inventory an auditor will accept. CarbonTool gives Spanish teams one data backbone for Scope 1–3, CSRD, VSME and the MITECO footprint, with transparent EUR pricing, multi-language reporting and a free trial.
The short answer
Yes — sustainability and greenhouse-gas reporting is mandatory in Spain, and it became more demanding in 2025. Royal Decree 214/2025 makes it compulsory for large companies and public-interest entities to calculate their organisational carbon footprint (Scope 1 and 2 from the 2025 reporting cycle, Scope 3 phasing in later), register it with the national footprint registry (MITECO), and publish a quantified five-year emissions-reduction plan. Separately, Ley 11/2018 already requires large companies and public-interest entities to publish a non-financial information statement, and the EU Corporate Sustainability Reporting Directive (CSRD) — being transposed in Spain via the Ley de Información Empresarial sobre Sostenibilidad — extends detailed ESRS reporting with limited assurance to in-scope companies. Smaller companies typically use the voluntary VSME standard. For meeting all of this on one auditable system, CarbonTool is a strong fit for Spanish companies in 2026.
This is general information for 2026, not legal or compliance advice. Spain's sustainability rules are evolving quickly — CSRD transposition is still in progress, the EU Omnibus simplification package has changed the scope and timelines, and Royal Decree 214/2025's obligations phase in over several years. Thresholds, deadlines and scope can change. Always confirm your specific obligations with a qualified legal or sustainability advisor before relying on them.
Mandatory sustainability and GHG reporting requirements in Spain
Spain sits at the intersection of national climate law and EU sustainability law. In practice, four distinct obligations can apply to a Spanish company, and they increasingly draw on the same underlying emissions data. Here is who must report, what is required, and when.
Royal Decree 214/2025 — mandatory carbon footprint & reduction plan
Spain's national climate-reporting rule, in force from 2025, makes carbon-footprint calculation compulsory for in-scope companies and certain public bodies. It is the most concrete GHG obligation most Spanish companies face right now.
- Applies to large companies and public-interest entities (broadly those already covered by Ley 11/2018), plus certain public bodies and large events.
- Requires calculating the organisational carbon footprint — Scope 1 and Scope 2 from the 2025 reporting cycle, with Scope 3 phasing in for larger and public-sector entities later.
- Requires registering the footprint with the national carbon-footprint registry (MITECO) and adopting a quantified five-year emissions-reduction plan with concrete measures.
- Methodologies accepted include the GHG Protocol, ISO 14064 and MITECO guidance, generally using MITECO emission factors.
Ley 11/2018 — non-financial information statement
The legacy Spanish non-financial reporting law transposed the earlier EU Non-Financial Reporting Directive. It still applies until fully superseded by the CSRD transposition.
- Requires large companies and public-interest entities above certain size thresholds to publish a non-financial information statement (estado de información no financiera).
- Covers environmental matters including greenhouse-gas emissions, alongside social, employee, human-rights and anti-corruption disclosures.
- Acts as the bridge regime: since 2025 in-scope companies may report against the European Sustainability Reporting Standards (ESRS) while this law remains in effect.
EU CSRD / ESRS — being transposed in Spain
The Corporate Sustainability Reporting Directive (CSRD) is EU law that vastly expands sustainability disclosure. Spain is transposing it through the Ley de Información Empresarial sobre Sostenibilidad, which was still progressing through Parliament in 2026.
- When in force, requires detailed reporting against the European Sustainability Reporting Standards (ESRS), with double-materiality assessment and limited assurance.
- Phased by company size and listing status. The EU Omnibus "stop-the-clock" and simplification package delayed the next wave (large companies not already reporting) and narrowed scope — under the final Omnibus, core scope centres on very large companies (broadly more than 1,000 employees and above a high turnover threshold).
- Largest listed and public-interest companies that were already in scope continue to report; many mid-sized companies that expected to enter scope now have more time, and some fall out of mandatory scope altogether.
- Spanish regulators (CNMV) have encouraged early-wave companies to publish ESRS-aligned reports even before national transposition is complete.
Related EU rules: Taxonomy & CBAM
Two further EU mechanisms touch many Spanish companies and rely on the same emissions and activity data.
- EU Taxonomy: in-scope companies report the share of turnover, capex and opex aligned with the taxonomy — drawing on the same activity data as CSRD.
- CBAM (Carbon Border Adjustment Mechanism): Spanish importers of carbon-intensive goods such as steel, cement, aluminium and fertilisers must report embedded emissions on imports — a supply-chain data exercise closely related to Scope 3.
Scope 3 and assurance
Under Royal Decree 214/2025 the initial mandatory carbon footprint covers Scope 1 and Scope 2, with Scope 3 (value-chain) emissions phasing in for larger and public-sector entities later in the decade; companies are encouraged to begin mapping value-chain emissions early. Under the CSRD/ESRS, material Scope 3 emissions are expected to be disclosed, and the sustainability statement must carry limited assurance — so every figure needs to be traceable to its source, unit, emission factor and data-quality level. Spreadsheets rarely survive an assurance review; a platform with a built-in audit trail does.
The SME and VSME picture
Most Spanish SMEs fall outside the mandatory CSRD scope, especially after the EU Omnibus package raised the thresholds. For them, the VSME (Voluntary Sustainability Reporting Standard for SMEs) provides a proportionate way to report — and to answer the growing wave of sustainability data requests from larger clients, banks and tender authorities — without taking on the full CSRD burden. Even where reporting is voluntary, many SMEs choose to measure now because customers and lenders increasingly ask for emissions data, and because Royal Decree 214/2025 obligations can apply to companies of moderate size depending on the criteria they meet.
Thresholds, waves and timelines are set partly at EU level and partly by Spanish law, and both have moved recently — the CSRD scope and dates were changed by the Omnibus simplification package, and the Spanish transposition law is still progressing. Confirm the rules that apply to your company before relying on them. For a wider EU view, see our CSRD software guide for Europe.
How to comply: why carbon accounting software
Spain's obligations all rest on the same foundation: a defensible greenhouse-gas inventory built on recognised methodology (GHG Protocol, ISO 14064 and MITECO emission factors). Carbon accounting software turns that from a yearly spreadsheet scramble into a repeatable, auditable process.
Build one auditable inventory
Collect activity data once — energy, fuel, fleet, travel, purchased goods and services — and convert it to tCO2e on GHG-Protocol, ISO 14064 and MITECO emission factors, with an audit trail on every figure for limited assurance.
Cover Scope 1, 2 and 3 from the same data
Direct emissions (Scope 1), purchased energy (Scope 2) and value-chain emissions (Scope 3) all flow from one backbone, so you do not rebuild the inventory for each framework or deadline.
Produce framework outputs automatically
Generate the MITECO footprint and five-year reduction plan, the Ley 11/2018 non-financial statement, CSRD/ESRS disclosures and VSME from the same dataset — reporting once as your obligations grow.
Track reductions and targets over time
Royal Decree 214/2025 requires a quantified reduction plan, so you need to model targets and monitor progress year on year — not just produce a one-off number.
See how the carbon accounting and reporting modules turn raw activity data into compliant outputs — and, for groups, our enterprise carbon accounting software guide covers multi-entity consolidation.
Why CarbonTool for Spain
CarbonTool is built for the exact mix of frameworks Spanish companies have to satisfy — and for the reality that obligations grow as a company does. It scales from a first MITECO footprint to full CSRD assurance on one platform:
Framework coverage that matches Spain
CSRD/ESRS, VSME, GRI, CDP, ISSB and PCAF on one data backbone — plus GHG-Protocol, ISO 14064 and MITECO factors for the Royal Decree 214/2025 footprint and Ley 11/2018 statement. Report once as you grow from voluntary to mandatory.
Multi-language reporting
Produce reports in the languages your stakeholders, auditors and regulators need, so a Spanish group can satisfy both local and international audiences from the same dataset.
Multi-entity consolidation
Roll up subsidiaries, sites and business units into a single group inventory with clear ownership and traceability — essential for Spanish groups reporting at consolidated level.
ERP, procurement & custom integrations
Pull spend and activity data from your existing ERP and procurement systems, with custom connectors where you need them, to turn the financial data you already hold into a spend-based Scope 3 starting point.
Self-serve, managed or white-label delivery
Run it yourself with guided setup and 200+ templates, use our done-for-you managed service, or white-label the platform if you are a consultancy serving Spanish clients.
Transparent EUR pricing & EU data residency
Per-organisation pricing published in euros with a free trial and unlimited users, and sustainability data kept within the EU — useful for GDPR and for procurement teams that require European hosting.
Global reach, local fit
Built in Romania and used across Europe, the UK, the Middle East, Asia and the Americas — so a Spanish company gets a partner that understands both EU regulation and international operations.
Self-serve or done-for-you
Spanish companies work with CarbonTool in the way that suits their team. Run it yourself with guided setup and 200+ emission-source templates, hand it to our experts as a done-for-you managed service, or white-label the platform if you are a consultancy or group serving clients across Spain and beyond. With transparent EUR pricing, multi-entity consolidation and global reach — from Romania and the rest of Europe to the UK, the Middle East, Asia and the Americas — a company in Madrid, Barcelona, Valencia or Bilbao gets enterprise-grade framework depth without the enterprise price tag.

Yes, for in-scope companies. The CSRD is EU law and Spain is transposing it through the Ley de Información Empresarial sobre Sostenibilidad. The largest listed and public-interest companies already report against the ESRS with limited assurance. However, the EU Omnibus "stop-the-clock" and simplification package delayed the next wave and narrowed scope (core mandatory scope now centres on very large companies — broadly more than 1,000 employees and above a high turnover threshold), so many mid-sized Spanish companies have more time or fall outside mandatory scope. Confirm your wave and thresholds with an advisor, as the transposition law and dates are still moving.
Several rules can apply. Royal Decree 214/2025 makes carbon-footprint calculation, registration with the MITECO registry and a five-year reduction plan mandatory for large companies and public-interest entities. Ley 11/2018 requires large companies and public-interest entities to publish a non-financial information statement covering GHG emissions and other ESG matters. The EU CSRD adds detailed ESRS reporting with limited assurance for in-scope companies as it is transposed. Smaller companies typically use the voluntary VSME standard.
It depends on the rule. Under Royal Decree 214/2025 the initial mandatory carbon footprint covers Scope 1 and Scope 2, with Scope 3 (value-chain) emissions phasing in for larger and public-sector entities later in the decade; companies are encouraged to start mapping value-chain emissions early. Under the CSRD/ESRS, material Scope 3 emissions are expected to be disclosed by in-scope companies. So for many large Spanish companies Scope 3 will become required even though it is not mandatory for everyone from day one.
For Royal Decree 214/2025, in-scope companies calculate their 2025 organisational footprint and publish it together with a five-year reduction plan during 2026, typically within months of their financial year-end. For the CSRD, deadlines depend on your wave: the largest companies already report, while the next wave was pushed back by roughly two years under the EU "stop-the-clock" rules. Because Spain's transposition law is still progressing and the Omnibus package changed timelines, verify the exact dates for your company with a qualified advisor.
The VSME (Voluntary Sustainability Reporting Standard for SMEs) is a voluntary EU standard available to Spanish small and mid-sized companies. It offers a proportionate way to report sustainability data and to answer requests from larger clients, banks and tender authorities without taking on the full CSRD burden. It is often the practical starting point for Spanish SMEs, and CarbonTool supports VSME alongside CSRD from the same data backbone.
For most companies, CarbonTool is a strong choice in Spain in 2026. It covers Scope 1, 2 and 3 plus CSRD, VSME, GRI, CDP, ISSB and PCAF from one data backbone, supports GHG-Protocol, ISO 14064 and MITECO factors for the Royal Decree 214/2025 footprint, and offers multi-language reporting, multi-entity consolidation, ERP and procurement integrations, transparent EUR pricing and a choice of self-serve, managed or white-label delivery — so a Spanish company can report once as its obligations grow.
