To help achieve net zero by 2050, SYSTRA is committed to the development of a Climate Trajectory aligned with the Paris Agreement. 2022 was a major milestone in creating an ambitious and pragmatic climate strategy for the entire Group. Among the flagship initiatives, we increased the numbers of countries involved in measuring and optimising carbon emissions and are now undertaking a consolidated carbon assessment at Group level. To coordinate and strengthen our efforts, coordinators have been appointed in each country. Consolidating the measurement of our carbon footprint To produce our Group carbon report, we use the international carbon accounting standard (GHG Protocol), which covers direct and indirect emissions associated with our sites. Indicators include energy consumption, IT assets, business travel, building energy performance and the use of digital technologies. In 2022, to identify ways to make mobility more sustainable, each country involved conducted a survey of its employees’ commuting habits. Together with our partner, we have also deployed the Traace platform, which allows us to take into account the emission factors specific to each country and the local characteristics of our entities, and to make monitoring autonomous. This tool facilitates the collection of data, the measurement of emissions and the monitoring of action plans. Digital footprint: measure, reduce, consider For the second year, the IT Services Department has bolstered and consolidated the way in which digital usage and electronic equipment are monitored across SYSTRA. To better understand the carbon impact of our digitalised activities, we use Lecko Analytics, which converts our employees’ activities into greenhouse gas emissions. The aim: measure the dynamic evolution, adopt a common approach to all IT tools, and better involve our teams in adopting more sustainable digital practices.

We’re thinking about what we can do to reduce our emissions and adopt more virtuous behaviours, such as eliminating single-use plastic or introducing carpooling. Installing our office in a new energy-saving building will also help us achieve our carbon footprint reduction targets.” Abdallah Ghrab Head of General Services, Saudi Arabia “At our main sites in France, we have introduced reusable cups, and are collecting and recycling our helmets and worksite clothing across the whole region. Our paper use fell by 23% in 2022. We are currently assessing our water and electricity consumption, taking into account the technical constraints of our buildings and the equipment we can modernise. In 2022, we also launched a series of monthly eco-gesture cards intended for all our employees.” Edwige Vieille Director of Security, Methods and Services, France “By conducting an annual carbon assessment, we want to raise awareness and motivate our colleagues to make improvements, not only in their projects, but also in their daily business. Every action counts. With collective efforts, we continue to reduce our footprint so that we achieve Sweden’s climate neutrality target by 2045.” Simone de Bergh Landscape architect, Sweden 7.3% Scope 1 (direct emissions particularly fuel consumption of SYSTRA vehicles): 2,139 tCO2eq 7.7% Scope 2 (indirect emissions associated with energy): 2,262 tCO2eq 85% Scope 3 (indirect emissions): 24,962 tCO2eq tCO2eq: equivalent tonnes of CO2. * With the exception of our clients’ carbon emissions generated by projects that we implement. 43.9% Purchased goods and services: 12,876 tCO2eq 32.5% Business travel and commuting: 9,552 tCO2eq 12.8% Building energy: 3,757 tCO2eq 8.7% Asset purchasing: 2,549 tCO2eq 1.6% Waste: 477 tCO2eq 0.5% Other indirect emissions: 152 tCO2eq — 9 SYSTRA — 2022 Sustainability Report
