The Spanish company SPG, specialised in flexible and sustainable packaging solutions, has received the “Calculo + Reduzco” seal from the Spanish Ministry for Ecological Transition and Demographic Challenge. The certification rewards companies that, in addition to calculating their carbon footprint, can demonstrate a measurable reduction over time. For SPG, this achievement confirms a long-term strategy focused on cutting emissions and improving the energy efficiency of its production processes.

What is the “Calculo + Reduzco” seal

Introduced by Spain’s Ministry for Ecological Transition, the Calculo + Reduzco programme forms part of the country’s official Carbon Footprint Register. Companies joining the scheme must first calculate their direct and indirect emissions and then demonstrate — with certified data — that they have achieved a measurable reduction compared with previous years.

The certification is divided into three stages: Calculo (calculation of the footprint), Reduzco (verified reduction), and Compenso (voluntary offset through environmental projects).

In SPG’s case, the Calculo + Reduzco seal covers the 2021–2023 period and reflects an overall reduction of 3.99% in greenhouse gas emissions at its main production sites in Andalusia. This result was achieved through a set of actions including the use of 100% renewable electricity, modernisation of industrial equipment and continuous monitoring of energy consumption.

The meaning and impact of the certification

Granted by Spain’s Ministry for Ecological Transition and Demographic Challenge, the Calculo + Reduzco seal confirms that SPG has verifiably reduced its greenhouse gas emissions from production activities. The evaluation is based on official data recorded in the national emissions register, which allows the progress of environmental indicators to be monitored over time.

Beyond formal recognition, the certification has a tangible operational value. It enables the company to document its environmental results transparently and to strengthen trust among clients and partners that require measurable sustainability standards. At the same time, registration with the public database managed by MITECO allows SPG to compare its environmental performance with that of other companies in the sector, promoting competition based on environmental, not only economic, criteria.

At a broader level, this recognition is consistent with the European framework that encourages companies to make their environmental impact traceable. The EU’s industrial policy and the Fit for 55 strategy promote progressive emission reductions and the adoption of recognised verification systems. Within this context, SPG’s pathway helps make the transition towards energy-efficient and resource-responsible production models more concrete.

Relevance for the United Kingdom and foreign markets

Although SPG has its roots in Spain, the Calculo + Reduzco certification has significance beyond national borders. The verified reduction of greenhouse gas emissions strengthens the company’s position in the European markets where it operates, including the United Kingdom. In a context where environmental traceability is increasingly required across supply chains, having an official certification of this kind provides assurance to clients and regulatory bodies alike.

In the packaging sector, major distributors and international brands now select their suppliers according to strict environmental criteria. Demonstrating with official data that emissions have been effectively reduced enables SPG to align with European sustainability standards and to respond more credibly to environmental compliance requirements in the UK market.

The case of SPG also highlights a relevant trend across the industry: the growing convergence among national carbon footprint regulations. Programmes such as Calculo + Reduzco anticipate, at state level, the direction taken by European and British policies on measuring, reducing and offsetting emissions in industrial operations. In this sense, SPG’s certification forms part of a shared approach to environmental responsibility connecting companies and institutions across countries.

Future perspectives for SPG and sustainable packaging

Experience gained through the Calculo + Reduzco certification has allowed SPG to consolidate a working method based on continuous monitoring of environmental impact. Energy data management and life cycle assessment of materials have become central tools in guiding production choices and anticipating regulatory demands affecting the entire packaging industry.

The company’s innovation strategy extends to research on recyclable and mono-material solutions designed to simplify post-use recovery. The testing of new lower-density plastic films and cooperation with suppliers to reduce raw material consumption form part of a long-term plan that links environmental sustainability with industrial competitiveness.

Growing consumer attention to the origin and composition of packaging reinforces the importance of a transparent, data-based approach. In this scenario, companies that integrate environmental evaluation into production decisions strengthen market trust and help define more coherent standards of shared responsibility between industry and society.
