Our Environmental Policy

Our carbon roadmap


of CO2 per employee by 2022

Based on 1.68 tCO2eq/employee in 2017 on emissions linked to our travel (by car and air), the energy consumption of our offices (electricity and gas) and waste management and recycling in our offices

Our approach is in line with the recommendations of the Paris Agreement on Climate Change, which provides for a 40% reduction in CO2 emissions by signatory countries by 2030 to restrict the rise in temperatures to less than 2°C. Kallista Energy wants to contribute as much as it can to this global objective. Moreover, we are especially aware of the CO2 emissions generated by the life cycle of the wind turbines that we install and that relate to our Scope 3 activity: the manufacturing, installation, decommissioning, recycling and recovery of wind turbines. We integrate environmental criteria in our choice of suppliers and opt for those that share similar requirements to our own.

Our commitments to the environment

  • 01. Electrify 80% of our vehicle fleet by 2022
  • 02. Ban domestic flights and limit international flights
  • 03. Avoid, reduce, and recycle waste from our offices
  • 04. Improve the energy efficiency of our equipment
  • 05. Encourage consideration of ESG criteria in activities within our scope 3
  • 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

2020 Carbon Footprint Of Kallista Energy

CO2 emissions

9,107 tonnes due to our wnid farms1

50,9 tonnes due to our "support" activity2

CO2 avoided

19,909 tonnes thanks to renewable energy production3

Two changes have been made in the methodology for estimating our 2019 carbon footprint compared to that of 2018 (more details in our 2019 CSR Report):

-Vehicle-related emissions now take into account the entire life cycle analysis of vehicles in order to integrate emissions related to construction and not just those related to fuel consumption. This new calculation method allows a more realistic assessment of electric vehicles.

-Due to our wind farm renewal plan, our calculations take into account a “depreciation” period of construction-related emissions shortened to 15 years as opposed to 20 years.

Even though not all CO2 emissions in this category fall within the direct scope of Kallista Energy (Scope 3), we endeavour to work with responsible suppliers who are also seeking to minimise their carbon footprint. ESG criteria are therefore systematically integrated in our contracts with our suppliers.

Minimising the environmental impact of our projects and our daily activity

We call on independent firms that are known for their expertise to conduct environmental impact studies prior to the construction of a wind farm. Studies into fauna, flora, acoustics and landscaping 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 decommissioning.

Consequently, Kallista Energy has committed to going beyond the regulatory requirements and completely removing all traces of the concrete foundations of the wind turbines, in order to return the land to farmers in its original state.

Moreover, we seek to limit the environmental impacts of our teams on a daily basis: electrification of our vehicle fleet; sorting and recovery of our office waste; replacement of appliances (lights, boilers, etc.) with more energy-efficient items.

Kallista Energy has also decided to completely ban all internal flights. SNCF season tickets and videoconferencing services are provided to our employees to allow them to travel quickly and comfortably anywhere in France, or to work remotely if they need to.
