Low carbon

The priority to consume less energy drives us and guides our choices throughout the design, construction and operation phases of our buildings. Limiting our greenhouse gas emissions is vital.


Reasons for our commitment 

Greenhouse gas emissions in the building sector account for 25% of all emissions produced in France. Cutting them is therefore a major challenge for the planet, and something we're fully aware of. To achieve this, we are taking action when it comes to designing, renovating, and managing our buildings. 

Material and equipment choice is geared toward the lowest emitters of greenhouse gases. When we renovate a building, we look for the most energy efficient solution. We make every effort to use low carbon or renewable energy sources in the buildings we operate. Our energy efficiency is measured and corrective actions are taken.

We act alongside our employees to involve our stakeholders −  customers and suppliers −  in this commitment each and every day. 


Our objectives

  • Cutting our greenhouse gas emissions 60% by 2030 (from 2008) and becoming carbon neutral by 2050

  • Making low carbon the standard when it comes to managing our operating portfolio by supporting our customers and training our staff in best practices 

  • Producing renewable energy in each of our buildings under development. 10 of our current projects are striving for 65 kWh/m2 in net total energy, or 4 times less than an average Haussmann-era office building

  • Instituting a carbon fund to finance our CSR projects and stimulate innovation 

Be Issy, a positive footprint on the city

As the first energy positive office building in the district, Be Issy produces more energy than it consumes. Discover

Our performance

Our commitment to low carbon manifests itself through our concrete initiatives and results but we are only at the beginning.

As at December 31, 2019

Our main initiatives 


We are ramping up our greenhouse gas-cutting initiatives. We also imposed an internal CO2 emissions tax on ourselves. 


  • We have introduced an internal carbon fund to accelerate the decarbonization of our portfolio 

  • 41% of our buildings are connected to urban heating networks 

  • We have installed a remote-reading system on 95 office building which represents 68% of our office portfolio

  • Photovoltaic panels were installed at “7 Madrid”

  • Although initially designed to be built with concrete, wood was chosen for the Domaine de la Ronce in Ville-d’Avray, i.e., 125 residences built using wood, yielding record CO2 gains: 180 kg/m3 for wood versus 400 kg for concrete

Our 4 CSR pillars

We are committed every day to safeguarding people, the planet, and the environment. The low carbon building is one of our 4 CSR policy pillars.


People are changing their mindsets and ways: we are meeting their expectations by enhancing their wellbeing at work and at home.
