Our four paths to more sustainable construction


Reducing CO2 emissions

We are one of the most carbon-efficient in the world and are committed to reducing emission levels in line with the COP21 2-degree scenario.


Reusing waste in operations

We reuse waste as a substitute for fossil fuels and other raw materials, addressing society’s waste problem.


Reducing water usage

We optimize and prevent the use of freshwater and mitigate the risk of water depletion or pollution, particularly in water-scarce areas.


Creating social value

We regularly interact with stakeholders at all levels to preserve our standing as good members of our communities.
