2 Strategy The Group’s environment SAINT-GOBAIN UNIVERSAL REGISTRATION DOCUMENT 2021 41 Saint-Gobain, through its unique position in the value chain, contributes to meeting the decarbonization challenge by offering its industrial and construction customers options that actively contribute to this objective (see chapter 3, section 2.1.4). The solutions sold by the Group in one year allow to reduce(1) CO2 emissions a total of nearly 1,300 million tons over their entire life cycle (thus exceeding by far the Group's own carbon footprint), by improving the energy efficiency of buildings and by avoiding emissions through light construction techniques. Saint-Gobain also plays a key role by helping to mobilize the entire building value chain towards a common goal of decarbonization. The Group is also working to reduce the impact of its own operations in terms of GHG emissions, in particular by constantly improving the efficiency of its processes. Environment and use of natural 1.1.2 resources The pressure on natural resources is increasing markedly, and yet their extraction continues to grow. The “day of exceedance” is the date on which humanity’s annual demands on nature (ecological footprint) exceeds the Earth’s capacity to regenerate natural resources over the entire year (biocapacity). If this benchmark day – calculated by the NGO Global Footprint Network (2) – was at the beginning of November in 1980, in 2021 it was July 29, indicating that it would take 1.75 planet Earths to meet the current global consumption of resources without exceeding the capacity of natural regeneration. However, economic crises prove that specific actions have tangible results: as the WWF notes, “The measures taken to deal with the pandemic have in fact pushed back the date by three weeks: the lockdown led to a reduction of the global carbon footprint of 14.5% (3)”.

According to the latest WMO account the gradual depletion of fossil resources report, more than five billion people will suffer from extracted, and in particular hydrocarbons. At the same insufficient access to water by 2050, i.e. more than half of time, it is estimated that the consumption of natural the world’s population (7). Here too, buildings play an resources has tripled over the last 50 years (5). Fresh water, essential role, accounting for 40% of energy consumption an essential and scarce resource (only 0.5% of the earth’s and also 12% of drinking water consumption, 38% of water is usable and available for consumption) is a greenhouse gas emissions and 40% of solid waste representative example of this trend: necessary for cities, production (8).
