Decarbonize. Optimize. Anticipate.

Decarbonize. Optimize. Anticipate.

Sustainably reducing CO₂ emissions while meeting the energy challenges of your business requires concrete solutions, adapted to your uses and constraints.
ALTENS supports you in your transition to more renewable and lower-carbon energies, relying on alternative fuels and energy performance solutions.

Effectively manage your decarbonization strategy

Our approach is based on support from the analysis of your needs to the implementation of energy solutions. We help you identify the most relevant levers to reduce your carbon footprint, secure your supply, and set your business on a more sustainable energy trajectory.

Why start a decarbonization process?

Reduce CO₂ emissions and energy consumption

Control energy costs

Anticipate regulatory changes

Secure long-term investments

We don't guess your energy. We measure it!

Altens’ consulting and support begins with a precise understanding of the site:

  • Consumption analysis
  • Energy usage mapping
  • Identification of highest-emitting areas
  • Process analysis
  • Economic and technical data
  • Site constraints and future needs

Moving from study to a concrete action plan

Short term

Altens first acts on what can be improved without heavy investment, in order to quickly achieve initial energy and carbon gains.

Medium term

We then move on to projects requiring studies and investments. This time, to sustainably reduce consumption and emissions.

Long term

Finally, we prepare for deeper changes to achieve a significant and lasting reduction in emissions.

Alternative Fuel Supply

Alternative fuels and biofuels to reduce your carbon footprint.

Renewable Electricity and Gas Supply

Greener, more local, and more responsible energy for your activities.

Energy Performance Financing (EEC)

Enhance your projects and give new momentum to your energy transition.

Renewable Electricity Production

Local and sustainable solutions to produce cleaner energy.

Deployment of New Technologies (EVCI, solar canopy...)

Innovative infrastructure for more sustainable mobility and energy storage.

Set your goals, reduce your emissions, and showcase your commitment!
