Since 2010, Groupe Rocher has been pursuing an ambitious carbon trajectory. By adopting an approach focused on energy sobriety, the company prioritizes directly reducing its consumption and transitioning to carbon-free energies. These efforts have already reduced CO2 emissions by 43% on scopes 1 and 2, and by 32% on scope 3 in five years.
In 2024, the group's 2030 targets were validated by the Science-Based Targets initiative (SBTi): a 42% reduction in carbon emissions on scopes 1 and 22 and 25% on scope 3, compared to 2022 levels.
A large-scale project: the solar carports in La Gacilly
At the heart of this strategy, the partnership with GreenYellow provides tailor-made solarization solutions to meet Groupe Rocher's energy ambitions. At La Gacilly, the group's headquarters and historic production site, the deployment of solar carports across 4 parking zones in 2025 will mark a significant milestone.
- 4,900 solar panels installed on an area of nearly 10,000 m²
- An installed capacity of 2.1 MWp, allowing an annual production of 2 GWh, equivalent to the energy consumption of 1,000 inhabitants.
- A 20-year self-consumption model, covering 16.7% of the site's energy needs, the equivalent of 2 months of annual consumption.
This initiative highlights GreenYellow's key role as a committed accelerator to the energy transition. Through its expertise in decentralized solar production and energy efficiency, GreenYellow allows Groupe Rocher to adopt a cleaner energy mix while optimizing its costs.
Local, sustainable and globally integrated impact
Beyond the production of renewable energy, this project illustrates a global approach in favor of the environment. The installation of solar caports is complemented by an ecological restoration component:
- Desartificialisation of 1,500 m² of soil, aimed at restoring the land to its natural function.
- Planting of 200 trees on the sites concerned, with the participation of the group's volunteer employees, strengthening local biodiversity and contributing to the quality of the ecosystem.
These combined actions reflect the Groupe Rocher's commitment to reducing carbon emissions and protecting the environment, while also improving the comfort of employees and visitors at its Morbihan sites.
A meaningful partnership
"We are proud to support Groupe Rocher in its energy transition and to contribute to the achievement of its ambitious decarbonization objectives. This solar carport project in La Gacilly perfectly embodies our vision: to offer innovative and tailor-made solutions that combine energy performance, respect for the environment and a positive impact on the territories. By combining our expertise, we show that a local and sustainable energy transition is possible. " says Mathieu Cambet, Deputy General Manager, in charge of solar photovoltaics at GreenYellow France
For Marion Decroix, Quality and CSR Director of Operations at Groupe Rocher : "This project is fully in line with our historical commitment to nature and the low-carbon transition. Thanks to our partnership with GreenYellow, we are strengthening the resilience of our La Gacilly sites while taking concrete action for a more sustainable future. This initiative reflects our ambition to build a sustainable harmony between our company, the territories where we operate, and the environment.''
