Our Environmental Policy

Our carbon roadmap

Our short-term climate targets are validated by the Science Based Targets initiative (SBTi)

A new carbon roadmap to eventually achieve Net Zero

Between 2017 and 2022, thanks to the combined efforts of all its employees, Kallista Energy was able to reduce its emissions per employee linked to its office activities by more than 40% (Scopes 1 and 2). The actions we have taken, in particular the electrification of our vehicle fleet and the efficiency of our heating equipment, have borne fruit.

In 2023, a new carbon roadmap has been defined and validated, with short-term objectives based on the methodology of the Science-Based Carbon Initiative (SBTi) to maintain the company’s contribution to the fight against climate change and achieve Net Zero by 2050.

  • Scope 3: Kallista Energy is committed to ensuring that 71% of its suppliers of emissions covering goods and services have science-based targets by 2027.
  • Scope 2 Kallista Energy is committed to increasing its annual electricity supply from 70% in 2021 to 100% by 2030.
  • Scope 1: Kallista Energy is committed to reducing its absolute GHG emissions by 50% by 2030 from a base year of 2021.

5 stars in the GRESB ranking

For the 5th year running, our company has been awarded 5 stars in the GRESB ranking, placing us 2nd in the “Onshore wind power generation / Operation & maintenance” category in Europe in 2023.

The GRESB is an independent organisation that publishes an annual ranking of companies according to their environmental, social and governance (ESG) commitments.


Our commitments to the environment

  • 01. Electrify 100% of our vehicle fleet by 2023*

  • 06. Develop the best projects with the help of independent experts
  • 07. Guarantee an exemplary site for each of our projects
  • 08. Ensure the environment is protected and noise disturbances are limited around our wind farms
  • 09. Invest in the repowering of our ageing wind farms to optimise renewable electricity generation
  • 10. Recover the blades of dismantled wind turbines and contribute to searching for solutions adapted to future volumes

*Commitment brought forward from 2024 to 2023

Minimising the environmental impact of our projects and our daily activity

To carry out environmental studies prior to the construction of a wind or solar farm, we call on independent firms recognised for their expertise. Studies of the fauna, flora, acoustics and landscape are carried out in strict compliance with the standards in force to minimise the environmental impact of the wind farm as much as possible, from its construction to its dismantling. The risks associated with extreme physical phenomena, natural disasters and climate change are also included in these studies.

Back in 2017, Kallista Energy committed to completely levelling the concrete foundations of the wind turbines during dismantling, before this principle was enshrined in law. The land where the wind turbines were installed can therefore be returned to farmers in their original state.

In addition, we seek to limit the environmental impact of our teams on a daily basis: electrification of our fleet of vehicles, sorting and recovery of waste in the offices, replacement of equipment (lamps, boilers, etc.) with more energy-efficient appliances.
