In 2026, Spain’s environmental regulatory framework will face two major regulatory changes.
This will have a direct impact on both industrial facilities and the organization of workplaces. On the one hand, the draft Royal Decree on atmospheric protection and the update to the CAPCA, currently in the public consultation phase, introduces a comprehensive overhaul of the air emissions control regime. On the other hand, Royal Decree-Law 7/2026 of March 20 significantly brings forward the deadline for complying with the requirement to have sustainable commuting plans in place.
Both initiatives reinforce a common approach: regulatory foresight, higher technical standards, and alignment with European objectives regarding public health, air quality, and reducing energy dependence.
A new Royal Decree to modernize air quality protection
The draft Royal Decree on the protection of the atmosphere represents a comprehensive update to the regulatory framework established by Law 34/2007, replacing and repealing regulations that, in some cases, had been in effect for decades. The stated objective is clear: to bring Spanish regulations in line with technical advances, the most recent European directives, and the current reality of industrial and energy activities.
One of the main focuses of the text is the comprehensive revision of the Catalog of Activities with the Potential to Pollute the Atmosphere (CAPCA). The new catalog is designed to be a more accurate and consistent tool that is aligned with emissions inventories.
The new version of the catalog includes new activities, adjusts power and capacity thresholds, corrects historical inconsistencies, and facilitates reclassification into groups (A, B, or C) based on actual pollution potential.
In addition, the Royal Decree introduces, for the first time, a basic and systematic system of emission limit values (ELVs) applicable to activities that previously lacked clear guidelines or were subject to outdated regulations. Of particular importance is the establishment of specific ELVs for sectors such as the drying of wet oil-rich pomace, crematoriums, asphalt mixing plants, and small boilers—areas that have traditionally been complex from an environmental control perspective.
The text also advocates for a more integrated approach to prevention, control, and monitoring, strengthening requirements for self-monitoring, external monitoring by accredited bodies, and the maintenance of emissions records over long periods, which is expected to lead to greater traceability and stricter inspection standards.
Reduced red tape and greater legal certainty (with the fine print)
Although the draft essentially retains the structure of Royal Decree 100/2011, it introduces significant changes to authorization and notification procedures, paving the way for administrative streamlining when equivalent sector-specific regulations or certified environmental management systems, such as ISO 14001 or EMAS, are in place.
However, this simplification is accompanied by greater responsibilities for facility operators, particularly with regard to the correct identification of activities, the reporting of changes, and effective compliance with emission limit values. In practice, the update to the CAPCA may entail changes in the administrative group and regime for certain facilities, which requires an advance technical review.
Sustainable commuting: the deadline is reduced from two years to one
Royal Decree-Law 7/2026 introduces a change to Law 9/2025 on Sustainable Mobility that will have a significant operational impact. Specifically, Article 63 reduces the maximum deadline for required workplaces to have a sustainable commuting plan in place from 24 to 12 months.
The requirement applies to workplaces with more than 200 employees, or more than 100 per shift, when that workplace is the employees’ usual place of work. According to the preamble to the Royal Decree-Law itself, the measure responds to the need to immediately reduce energy costs associated with commuting, in a context of high price volatility and dependence on fossil fuels.
This earlier deadline is forcing many organizations to rethink their internal schedules. The impact is greatest on those that had planned to implement these plans at later stages of the law’s rollout.
In addition, failure to comply with this requirement may have further consequences for companies receiving public aid under the Royal Decree-Law itself.
A clear message for affected businesses and facilities
The common thread between the two regulations is clear: tighter deadlines and stricter technical requirements. Whether regarding air emissions or sustainable mobility, lawmakers are sending a clear signal that they are staying ahead of the curve and aligning with European goals of zero pollution and the energy transition.
