Cubner's CSR Commitment: Maritime Container and Circular Economy
At CubnerWe believe that the storage of tomorrow should not be built at the expense of the planet. As a maritime container specialist since 2014, our mission naturally falls within a framework of sustainable development,Transforming a used container, which has been in service for years, before being reused as a storage solution, gives a second life to a robust structure, thus reducing the carbon footprint associated with new construction.

1. Environmental Commitment: Circular Economy of the Maritime Container
The 3Rs principle (Reduce, Reuse, Recycle) is the foundation of our daily operations. An unused shipping container represents tons of steel that can be reused without extensive processing.
- Systematic Upcycling: We favour the refurbishment of "last voyage" shipping containers to limit the industrial impact.
- Eco-friendly insulation: For our arrangements with CalcubWe select materials that offer optimal thermal insulation to minimize energy consumption (for example, sprayed cork).
- Extreme Durability: By extending the life of containers over several decades, we are fighting against the planned obsolescence of temporary storage structures.
2. Sustainable Logistics: French Carriers and B100 Biofuel
Logistics is at the heart of our business, but also our main lever for climate action. Cubner is committed to a responsible supply chain by acting on two major axes: local sovereignty and the decarbonization of transport.
A Collaboration with Local Transport Providers
We made the strategic choice to work primarily with French transport subcontractorsThis choice guarantees:
- Improved responsiveness and expertise in the French territory and more broadly in Europe.
- Supporting the local economy and the expertise of our regions.
- A reduction in "light-footed" kilometers (empty journeys) thanks to a dense territorial network.
The Choice of Rapeseed: The B100 Biofuel
To drastically reduce the carbon footprint of your deliveries, Cubner prioritizes partners using the B100 biofuelThis fuel, derived from French rapeseed cultivation, offers major ecological advantages:
- 60% reduction in CO2 emissions minimum compared to fossil diesel.
- Reduction of fine particles by up to 80%, thus preserving air quality.
- 100% renewable energy and not relocatable, sourced from French agriculture.
Environmental impact
du container transport
Compare CO₂ emissions and energy consumption according to the mode of transport, on your actual journeys.
Reading: each cell indicates the % of emissions saved by choosing the online mode rather than the column mode.
Replacing a concrete structure with a reused shipping container saves between 10 and 15 tonnes of CO2e for a 28 m² (40-foot) container. This exceptional result, validated by data from theADEMEThis is contingent upon the use of second-hand containers. For a new container, the environmental impact of steel production negates the ecological benefit, making reuse essential to achieving decarbonization goals.
3. Social Commitment and Professional Ethics
CSR at Cubner doesn't stop at the environment. It also concerns the women and men who contribute to our success.
- Safety and Quality: All our transformations comply with the strictest safety standards to protect our teams and our clients.
- Total Transparency: We ensure complete traceability of the origin and condition of our containers.
- Collaborative Innovation: We encourage our employees to propose innovative solutions to improve our societal impact.
4. Cubner, the benchmark for sustainable storage solutions for businesses
Choosing Cubner means opting for a partner that integrates climate issues into its business model. We support businesses, local authorities, and individuals in achieving a concrete ecological transition through modular construction.
Our CSR approach is an ongoing commitment. Through the optimization of our logistics at rapeseed B100 and the promotion ofcircular economyCubner has established itself as the trusted partner for your sustainable storage projects.

What is CSR at Cubner?
At Cubner, CSR (Corporate Social Responsibility) translates into a concrete commitment to the circular economy. By reusing second-hand shipping containers for storage and modular housing, Cubner gives these steel structures a second life, thus reducing its clients' carbon footprint by more than 95% compared to new construction. We also use bio-based materials (sprayed cork for insulation, wood wool) and transport them using B100 biofuel.
What is the carbon footprint of a used shipping container versus a new one?
According to data from ADEME (Base Carbone), a used 20-foot shipping container generates approximately 0,2 tonnes of CO2 equivalent, compared to 4,4 tonnes for a new one. This represents a 95,5% reduction in greenhouse gas emissions. For a 40-foot container, the savings are even more significant: 0,4 tonnes of CO2 equivalent versus 8,6 tonnes of CO2 equivalent, or 8,2 tonnes of CO2 avoided per container.
How does Cubner reduce its carbon footprint for deliveries?
Cubner works with transport companies that use B100 biofuel, a 100% plant-based fuel made from rapeseed grown in France. This biofuel reduces CO2 emissions from deliveries by 60% compared to conventional diesel, and fine particulate emissions by 80%. By choosing a French agricultural supply chain, Cubner also supports the local economy and reduces fuel supply distances.
Why choose a used container rather than a new build?
Choosing a used shipping container offers numerous advantages: a 95% reduction in CO2 emissions compared to new construction, reuse of existing steel avoiding new mining operations, an extended lifespan of 15 to 30 years, costs up to 40% lower than traditional construction, and unparalleled speed of implementation. It's a concrete circular economy solution for storage, modular housing, and offices.
Is Cubner CSR certified?
Cubner is committed to a voluntary and transparent CSR approach. The company publishes its environmental impact data, uses bio-based materials for insulation, trains its teams in eco-responsible practices, and develops partnerships with local stakeholders. Cubner actively and regularly works to reduce its carbon footprint in order to improve its processes.
What is the B100 biofuel used by Cubner?
B100 (or Oleo100) is a 100% plant-based biofuel produced from rapeseed grown in France. Unlike conventional biodiesel (B7 or B30), it contains no fossil fuels. Its advantages include: 60% lower CO2 emissions compared to diesel, 80% fewer fine particles, zero sulfur, and 99% biodegradability in 21 days. It is approved for heavy goods vehicles and used by Cubner for all its container deliveries within France.
