Introduction
Spain has taken a decisive step in the fight against climate change by enforcing mandatory carbon reporting under its Climate Emergency Plan. Anchored in Royal Decree 214/2025 and supported by Law 7/2021 on Climate Change and Energy Transition and Law 11/2018 (Spain’s transposition of the NFRD), the regulation transforms voluntary disclosure into a binding requirement. This makes Spain one of the first EU member states to introduce national rules that require companies to disclose their emissions data in a standardized way. The move underscores the growing emphasis on corporate transparency in environmental performance, and it positions Spain as a testing ground for the broader European Union (EU) agenda on sustainability disclosure.
For companies, the implications are profound. Executives, sustainability managers, and investor relations teams must now integrate carbon reporting into their corporate governance frameworks. This blog explores the details of Spain’s new requirements, how they compare with EU-wide rules like the Corporate Sustainability Reporting Directive (CSRD) and the Emissions Trading System (ETS), and what these changes mean for companies operating in Spain.
1. Overview of Spain’s Climate Emergency Plan
The Climate Emergency Plan requires companies above specific thresholds to measure and disclose their greenhouse gas emissions. The key features include:
- Scope: Companies with more than 250 employees, or assets greater than €20 million, or turnover exceeding €40 million for two consecutive years must comply. Public entities and large event organisers (with over 1,500 attendees) are also included. SMEs are indirectly affected through supply chain pressures.
- Metrics: Standardized greenhouse gas emissions reporting, covering Scope 1 (direct), Scope 2 (indirect), and Scope 3 (value chain). Scope 1 and 2 are mandatory from 2025 data, with Scope 3 reporting required from 2028 for large entities.
- Timelines: First reports due in 2026, covering 2025 data. Annual disclosures required thereafter, accompanied by five-year quantified greenhouse gas reduction plans published online or via the national carbon register.
- Penalties: Non-compliance can result in financial penalties and exclusion from public procurement processes, in addition to reputational risks.
- Assurance: Certain entities, especially large companies, must obtain third-party verification of their reports. Oversight is carried out by MITECO, the Ministry for Ecological Transition and Demographic Challenge.
This proactive step reflects Spain’s ambition to accelerate its path toward climate neutrality and align corporate accountability with national climate goals.
2. Comparison with EU-wide Requirements
Spain’s regulation does not exist in isolation. It interacts with EU-wide frameworks, creating both challenges and opportunities for companies.
CSRD (Corporate Sustainability Reporting Directive):
- Applies to large companies and listed SMEs across the EU.
- Requires disclosure of sustainability impacts, including emissions, based on European Sustainability Reporting Standards (ESRS).
- Spain’s plan accelerates the timeline by requiring emissions reporting before CSRD becomes fully operational.
EU ETS (Emissions Trading System):
- Applies to energy-intensive industries such as power, cement, and steel.
- Focuses on emissions allowances and trading, not broad corporate transparency.
- Spain’s rules extend disclosure to companies beyond ETS sectors, capturing a wider share of the economy.
Streamlining vs. Overlap: While Spain’s plan could create duplication, it may also help companies prepare for EU-wide compliance. Early adoption of reporting practices in Spain can smooth the transition to CSRD and ensure alignment with investor expectations.
Table: Spain vs. EU Reporting Frameworks
| Feature | Spain Climate Emergency Plan | EU CSRD | EU ETS |
|---|---|---|---|
| Scope of Companies | Large companies >250 employees, €20M assets, €40M turnover; public entities; large event organisers | Large companies, listed SMEs | Energy-intensive sectors only |
| Type of Disclosure | Mandatory emissions reporting (Scopes 1, 2, 3 from 2028) + five-year reduction plans | Broader sustainability disclosure | Emissions trading obligations |
| Timeline | Reports from 2026 (covering 2025 data) | Phased rollout through 2025–2028 | In place since 2005 |
| Penalties for Non-Compliance | Financial penalties, exclusion from procurement, reputational risks | National-level enforcement | Allowance shortfalls, fines |
3. Implications for Companies Operating in Spain
For businesses, Spain’s mandatory carbon reporting introduces both administrative challenges and strategic opportunities.
- Data Collection: Companies must implement or upgrade emissions tracking systems to meet reporting standards. Manual processes will struggle; digital platforms and ESG software can automate compliance.
- Compliance Costs: Smaller firms may face disproportionate burdens, requiring external consultants or technology solutions.
- Multinationals: Will need to reconcile Spanish requirements with global reporting frameworks such as GRI, SASB, and TCFD.
- SMEs: Although compliance may be difficult, early adoption can provide an edge in supply chains where buyers demand transparency.
- Technology Solutions: ESG software, such as Asuene’s carbon accounting platform, can automate data collection, engage suppliers for Scope 3, ensure ESRS alignment, and generate audit-ready reports for assurance.
Investor relations teams should anticipate heightened scrutiny. Carbon reporting is no longer optional, and investors will use these disclosures to evaluate both risk exposure and opportunities for long-term growth.
4. Strategic Opportunities and Risks
Spain’s mandatory carbon reporting is not only a compliance exercise but also a chance for companies to demonstrate leadership.
Risks:
- Fines, exclusion from procurement, and reputational damage from non-compliance.
- Increased investor scrutiny if disclosures reveal high carbon intensity.
Opportunities:
- Early movers can differentiate themselves in capital markets.
- Companies can use emissions data to identify inefficiencies, reduce costs, and innovate.
- Transparent reporting strengthens brand reputation with consumers and employees.
- ESG software can transform compliance data into strategic insight, supporting long-term sustainability performance.

5. Conclusion: Spain’s Role in Shaping Europe’s ESG Future
Spain’s new reporting rules are more than a national regulation. They are part of a larger European shift toward climate accountability and corporate transparency. By acting early, Spain provides a preview of how mandatory carbon disclosure may spread across the EU.
For companies, this is a call to action. Rather than viewing compliance as a burden, forward-looking firms can integrate carbon reporting into strategic planning. Doing so not only ensures regulatory compliance but also enhances competitiveness in an economy where sustainability is increasingly a determinant of success.
Spain’s initiative highlights a broader truth: the future of business in Europe is inseparable from climate responsibility. Companies that adapt quickly will not only meet the requirements but also shape the market narrative around sustainability.
