ESG and Carbon Reporting in Spain: Practical Compliance for International Companies and Spanish Subsidiaries

Spain’s ESG regulatory landscape: two obligations, not one

International companies with Spanish operations frequently approach their Spanish ESG compliance through the lens of group-level CSRD reporting, assuming that what the group produces for the parent entity will automatically cover Spain. This assumption is incorrect in two important respects.

First, CSRD applies at entity level. A Spanish subsidiary that meets two of three size criteria — more than 250 employees, more than €50M in net turnover, or more than €25M in total assets — is independently subject to Spain’s LEIS transposition of CSRD and must produce, or formally contribute to, a CSRD-compliant sustainability report for fiscal year 2025. The group parent report may satisfy this obligation only if the consolidation exemption conditions established in LEIS are met, which requires specific analysis.

Second, and separately, Spain’s Royal Decree 214/2025 creates a carbon footprint declaration obligation that has no equivalent at EU level. It is a domestic Spanish regulation with its own scope, methodology, verification requirements, and enforcement regime. A company with Spanish manufacturing or logistics operations may be subject to RD 214/2025 regardless of whether it falls within CSRD scope — and the deadline for the first declaration covers fiscal year 2024.

Who is affected and when: the Spanish CSRD calendar

The CSRD reporting calendar in Spain follows the EU-wide phased schedule, now implemented through LEIS:

FY2024 reports (published 2025): Companies already subject to Spain’s former EINF law (Ley 11/2018), essentially large listed companies with more than 500 employees. These entities are already publishing their first ESRS-compliant reports.

FY2025 reports (published 2026): All large companies — listed or unlisted — meeting two of three CSRD size criteria. This represents the largest single expansion of ESG reporting obligations in Spanish corporate history, bringing several thousand additional companies into scope.

FY2026 reports (published 2027): Listed SMEs on EU regulated markets, with the option to apply the simplified ESRS for SMEs standard.

FY2028 reports (published 2029): Third-country companies with more than €150M in EU turnover and significant EU subsidiaries or branches. This catches non-EU parent groups whose Spanish operations alone may not trigger the threshold.

The three scopes of carbon reporting under RD 214/2025

For companies subject to Spain’s carbon declaration obligations under RD 214/2025, the methodology follows the GHG Protocol, which the Spanish regulation adopts as its reference standard. The three scopes are:

Scope 1 — Direct emissions: Combustion in company-owned or controlled sources (boilers, furnaces, generators), industrial processes that release GHGs, and emissions from company-owned vehicles. These are measured directly from energy consumption data and are typically the most straightforward to calculate.

Scope 2 — Purchased electricity: Indirect emissions from the generation of electricity consumed by the company. Spain’s grid emission factor is published annually by IDAE (Institute for the Diversification and Saving of Energy). Companies with renewable energy certificates (GOs or RECs) can apply a market-based method that reduces or eliminates Scope 2 emissions — an important tool for companies with sustainability commitments.

Scope 3 — Value chain emissions: The most comprehensive category, covering all other indirect emissions: upstream from suppliers of materials and services, downstream from use of products sold and their end-of-life treatment, business travel, employee commuting, and logistics by third parties. For most companies, Scope 3 represents the majority of total emissions. RD 214/2025 increasingly expects Scope 3 disclosure, particularly for companies in supply chains of large CSRD-subject customers.

Coordinating Spanish entity ESG data with group reporting

The practical challenge for international groups is ensuring that Spain-specific ESG data collection happens in parallel with — and feeds into — the group-level reporting process. Several coordination points require attention:

Emission factors: Spain uses specific grid emission factors and regulatory calculation methodologies that may differ from those applied by the group’s global ESG team. Applying group-default factors to the Spanish entity’s energy data can produce declarations that do not comply with RD 214/2025 requirements.

Double materiality at entity level: CSRD requires a double materiality analysis that reflects the specific context of the reporting entity. A Spanish manufacturing subsidiary’s material topics may differ significantly from those of the parent group — for instance, water stress in Mediterranean operating locations, or Spanish labour law implications for the workforce disclosures.

Spanish language requirements: LEIS will require that sustainability reports of Spanish entities be available in Spanish. Groups producing their consolidated CSRD report in English will need to ensure the Spanish entity sections are properly localised.

Registry submissions: The RD 214/2025 carbon declaration must be submitted in Spanish to the Ministry for Ecological Transition’s Carbon Footprint Registry, using specific online forms. This is a separate administrative act from any group-level reporting.

ESG data as commercial infrastructure: financing and procurement

Beyond regulatory compliance, Spanish ESG data serves critical commercial functions that international companies sometimes underestimate:

ICO green financing: Spain’s Official Credit Institute (ICO) operates green financing lines that apply preferential interest rates and extended terms to companies and projects demonstrating sustainability credentials. These programmes require verified ESG data and are increasingly important for financing Spanish capital expenditure.

EIB and NGEU funding: European Investment Bank loans and Next Generation EU (recovery fund) grants for Spanish projects carry ESG eligibility criteria. Spanish subsidiaries investing in decarbonisation, energy efficiency, or sustainable infrastructure need structured ESG data to access these instruments.

Spanish public procurement: Spain’s Public Sector Contracts Law (LCSP) requires contracting authorities to include environmental and social criteria in tender evaluations above certain thresholds. Companies without ESG documentation are increasingly disadvantaged in public procurement.
