Environmental declarations for 2025: key obligations and deadlines for businesses

The deadline for submitting the main environmental declarations relating to activities in 2025 is 31 March. These are a set of administrative obligations that apply to industrial companies, waste management operators and other activities with an environmental impact.

Compliance with these requirements is not only necessary from a regulatory perspective but also contributes to more efficient and responsible business management.

Below, we outline the main declarations and who they apply to.

Annual Industrial Waste Declaration (DARI)

The DARI collects information on the waste generated by a production facility throughout the year.

There are two types:

• Standard: for production sites with more than 5 employees, regardless of whether they are directly involved in the production process.
• Simplified: for production sites with up to 5 employees.

Annual Waste Declaration for Waste Managers (DARIG)

This declaration applies to sites that carry out waste management activities.

Depending on the type of activity, it may be necessary to provide additional information, as in the case of:

• Managers of end-of-life vehicles (ELVs).
• Managers of waste electrical and electronic equipment (WEEE).

In addition, the annual report provided for in Article 65 of Law 7/2022 of 8 April must also be submitted.

PRTR: Pollutant Release and Transfer Register

The PRTR collects annual data on emissions and waste transfers from each facility:

• Emissions to air, water and soil
• Waste transfers

This reporting is mandatory for certain facilities and enables the environmental impact of the activity to be monitored.

In the case of livestock farms, the submission deadline is extended to 30 April.

Annual Packaging Declaration (DAE)

The DAE includes information on the quantity of packaging and packaged products placed on the market throughout the year.

This declaration is key to the control and traceability of packaging within the current regulatory framework.

Solvent Management Plan (PDG)

The PDG is mandatory for establishments that use solvents in their production processes or in dry cleaning activities. It enables the associated emissions to be controlled and minimised.

Automatic Monitoring System (AMS)

Establishments with emission sources that require continuous monitoring of a pollutant must manage and report this data using automatic monitoring systems.

Planning and regulatory compliance

The management of environmental declarations requires planning, rigour and regulatory knowledge. Centralising information, validating data and submitting it on time is key to avoiding incidents and ensuring legal compliance.

It is therefore advisable to check in advance which obligations apply to each activity and ensure that all information is correctly compiled.
