Methodology SYSTRA is bound by its regulatory non-financial reporting obligations as provided for in Law no. 2017-1180 of 19 July 2018, and in the order enacted pursuant to Law no. 2017-1265 of 9 August 2017. The Sustainability Report meets these obligations. This report for 2022 presents SYSTRA’s main challenges and achievements in relation to sustainable development. To establish the reporting scope, it was decided to use the financial consolidation scope which includes all of the SYSTRA Group’s subsidiaries. The quantitative information given in the social and environment sections mostly applies to the SYSTRA SA legal entity and its French subsidiary SYSTRA France, excluding branches. This represents 2,242 employees, namely 25.2% of the Group’s total workforce as of 31 December 2022. The reporting period is for the calendar year, from 1 January to 31 December 2022. There may be some methodological limitations associated with the environmental and social indicators. This is because of a lack of standardisation across definitions and local practices, and the availability of certain data over a limited scope. SYSTRA is committed to an ongoing progress and improvement approach so as to bolster its internal reporting process and increase the reliability of the data that we share. A reporting protocol, completed with definitions of the indicators used, together with information about the various data collection and consolidation procedures has been updated and is shared each year with the relevant contributors. For 2022, the key performance indicators published by SYSTRA which have been audited by Mazars are: Social information • Group workforce and breakdown of employees by gender and geographical region. • Women-men equality index (SYSTRA France and SYSTRA SA). • Share of women making up the Global Leadership Team, the Supervisory Board and the Group’s top 100 managers. • Percentage of employees trained during the year (SYSTRA France and SYSTRA SA). • Number of hours of training per employee on key issues (SYSTRA France and SYSTRA SA). • Number of potentially serious incidents which resulted in or could have resulted in the death or permanent disability of our employees (including those which did not have any actual consequences). • Share of employees who have received training on the “9 Life Saving Rules”. • Frequency rate (SYSTRA France and SYSTRA SA). • Percentage of letters returned confirming compliance. • Percentage of employees who have followed the online course on the anti-corruption code of conduct. • Client satisfaction rate on projects. Environmental information • Countries involved in the carbon footprint process: Australia, Brazil, Canada, France, India, Italy, Saudi Arabia, Sweden, United Kingdom and Ireland, United States. • Carbon assessment – Direct and indirect GHG emissions per country: – Scope of common carbon assessment: purchase of furniture(1), purchase of IT equipment, purchase of services(2), purchase of cars, energy consumption (scopes 1, 2 and 3), waste(3), commuting trips, business trips(4), refrigerant fluids(5), catering(6), digital uses (e-mails, OneDrive, SharePoint); – United Kingdom/Ireland: energy consumption when working remotely. The carbon footprint of the ten countries involved has been extrapolated on the basis of the number of employees in order to consolidate the results at Group level. The following information has been excluded since it does not apply to the Group’s activities: tackling food waste, tackling food poverty, ensuring animal welfare and a responsible, equitable and sustainable diet, initiatives designed to promote the practice of sport and physical activity.
