Does your business need to report its carbon footprint in Spain? Royal Decree 214/2025 has made emissions reporting and reduction planning mandatory for many organisations. Here's what you need to know.
Carbon data is no longer just a sustainability nice-to-have. It’s becoming business-critical. Royal Decree 214/2025 makes this shift official in Spain, introducing mandatory carbon reporting for many organisations operating there.
This article explains what the regulation requires, who it affects, and what businesses should consider as reporting obligations take effect. If you operate in Spain, or supply businesses that do, this is worth ten minutes of your time.
Spain has run a voluntary carbon footprint registry since 2014 under Royal Decree 163/2014. Royal Decree 214/2025 strengthens that framework by making reporting mandatory for organisations within scope.
Affected organisations must:
The introduction of mandatory reduction planning is a significant change. Organisations are no longer expected simply to measure emissions; they must also show how they plan to reduce them over time. This puts long-term carbon management firmly on the agenda, not just annual reporting.
To keep reporting consistent and comparable, emissions must be calculated using recognised international methodologies, including the Greenhouse Gas Protocol and ISO 14064-1.
At a minimum, organisations must report:
Scope 3 emissions aren’t currently mandatory for most organisations under the decree, but they’re becoming harder to ignore. Many businesses already receive requests for value chain emissions data from customers, investors and reporting frameworks looking for greater visibility across supply chains.
Understanding Scope 3 emissions now, even ahead of any formal requirement, can give a fuller picture of environmental impact and help identify future reporting risks before they arrive.
The regulation mainly applies to large organisations already subject to Spain’s non-financial reporting requirements, along with certain public sector entities.
This generally includes organisations with:
Importantly, the regulation applies only within the scope of Spanish reporting requirements. It doesn’t automatically extend to UK operations or wider global activities outside the reporting boundary of the relevant Spanish entity. For multinational organisations, working out clear organisational boundaries is a critical first step in deciding exactly which emissions sources need to be included.
Even businesses outside the direct scope are likely to feel the effects. Large organisations increasingly ask suppliers for carbon data to support their own reporting obligations and procurement decisions. The question for many businesses isn’t whether emissions information will be requested, but how prepared they’ll be when it is.
Royal Decree 214/2025 came into force in June 2025, and organisations within scope are now progressing through their first mandatory reporting cycle. For many, disclosure of 2025 emissions data and reduction plans is already underway.
For businesses that haven’t yet established robust carbon accounting processes, time matters. Emissions data is often scattered across facilities, suppliers, departments and systems, which makes collection and validation harder than many organisations expect.
Building a reliable carbon footprint takes more than gathering energy bills. It requires:
Delaying this work tends to make compliance more resource-intensive later, and increases the risk of reporting gaps.
Carbon footprint data increasingly supports procurement decisions, supplier assessments, sustainability disclosures, investment evaluations and decarbonisation planning. Organisations that can provide reliable emissions data, and show progress against reduction targets, are often better placed to respond to tender requirements and stakeholder scrutiny.
Preparing a carbon footprint also tends to surface useful operational insights. Understanding where emissions come from can highlight inefficiencies and help prioritise reduction activity. For many organisations, measuring emissions becomes the starting point for a broader carbon management strategy, supported by our SECR services and carbon management support.
Royal Decree 214/2025 is part of a wider move towards greater carbon transparency across Europe. Similar expectations already exist through the UK’s Streamlined Energy and Carbon Reporting (SECR) regime, while the Corporate Sustainability Reporting Directive (CSRD) continues to expand disclosure requirements across the EU.
The direction is consistent: regulators, investors, customers and procurement teams increasingly expect organisations to understand their emissions, disclose performance and show measurable progress.
For businesses operating in Spain, compliance with Royal Decree 214/2025 is best treated as a starting point, not an end goal. A robust carbon footprint, a clear view of emissions hotspots, and a credible reduction strategy will help you respond to today’s obligations and tomorrow’s expectations.

It’s Spanish legislation that makes carbon footprint reporting and emissions reduction planning mandatory for certain organisations operating in Spain.
Broadly, large organisations already subject to Spain’s non-financial reporting requirements, including those with more than 500 employees, consolidated reporting obligations, or public interest status.
Not currently mandatory for most organisations under the decree, though it’s worth preparing for given wider market and supply chain expectations.
It came into force in June 2025, with organisations within scope now in their first mandatory reporting cycle.
