Arcadis

Carbon per million dollars of revenue. The legacy industry-standard reference (CDP, MSCI). Useful for cross-sector context, but distorted by margin — high-margin firms appear artificially efficient. Read alongside the operational and asset intensities for the full picture.

OpEx (operating expenditure) is the running cost of the business — staff, services, energy, materials. This shows how carbon-intensive operations are per million dollars of spend. Removes the margin distortion that revenue-based ratios introduce.

EVIC (Enterprise Value Including Cash) is the firm's total capital footprint — equity + debt + cash + minority interest. The EU's standard intensity measure (SFDR PAI 3) — answers: how much carbon does each million of capital deployed in this business produce?

PP&E (Property, Plant & Equipment) plus leased real-estate assets is the firm's physical infrastructure on the balance sheet. This shows the carbon intensity of that physical footprint — uses Scope 1+2+3 for consistency with the other headline intensities. Surfaces stranded-asset risk for asset-heavy firms.

Carbon per FTE (full-time-equivalent employee) — the diagnostic measure for people-leveraged businesses where headcount, not capital, drives delivery. Captures the office, energy and travel footprint per person.

Arcadis purchases Renewable Energy Certificates (RECs/GOs) to cover 100% of its electricity use, resulting in a reduction of approximately 7,200 tCO2e in 2025 Scope 2 emissions and keeping market-based Scope 2 emissions 97% lower than location-based emissions. The share of energy from contractual instruments (RECs, GOs, etc.) was 78% of total energy consumption in 2025 (83% in 2024). Self-generated solar electricity from office rooftops contributed 537 MWh in 2025. The company also integrates sustainability clauses into leases and prioritises third-party accredited office properties (LEED, BREEAM), receiving 2025 Green Lease Leader Silver recognition from IMT.

To achieve net zero by 2035, Arcadis plans to neutralise residual GHG emissions (after a 90% reduction) by investing in carbon removal projects, including a reforestation project in India launched in early 2023 with Fair Climate Fund India. Resulting removal credits will be verified under the PLAN VIVO framework. In parallel, Arcadis purchases REDD carbon offset credits for Scope 1, 2 and selected Scope 3 categories (2-7) from the 'Nii Kaniti' forest conservation project in Peru (VERRA VCS & CCB, project 1360), with approximately 62,000 tCO2e contracted annually. These credits are not deducted from reported gross emissions but are used beyond the value chain.

• Business travel carbon budgets and travel management to cut Scope 3 Cat 6

  In 2025, Arcadis launched its first business travel carbon budgets at the group business unit level, resulting in a 21% reduction in business travel emissions (from 34,250 tCO2e in 2024 to 27,200 tCO2e in 2025). Quarterly personalised traveller emissions reports are sent to individual employees, and a consolidated travel management provider with integrated carbon emissions data was adopted. An updated travel policy focuses on large meetings, long-haul business travel and short-haul rail travel. The company also participates in the KLM-Air France Sustainable Aviation Fuel (SAF) programme, though SAF credits are not deducted from declared emissions.

• Fleet electrification to cut Scope 1 vehicle emissions

  Arcadis is transitioning its leased vehicle fleet to electric vehicles (EVs) with a target to complete the transition by 2030. By end-2025, EVs comprised 43% of the fleet (up from 35% in 2024), and internal combustion engine vehicles were reduced by 16%. EV transition is expected to cut fleet emissions by approximately 6,600 tCO2e—about two-thirds of combined Scope 1+2 market-based emissions. Fleet electrification is classified as a medium-impact, medium-to-short-term measure managed by Global Business Areas and People.

• Office consolidation, hybrid working, and gas-to-electric heating conversion

  Arcadis leverages hybrid working and office space reductions to lower Scope 1 and 2 emissions through reduced energy consumption. Office consolidation combined with switching from natural gas to electricity or biogas for heating is estimated to reduce emissions by approximately 2,500 tCO2e (about one quarter of combined Scope 1+2 market-based emissions). Scope 2 location-based emissions fell 21% in 2025, approximately 60% below 2019 base year, partly due to these measures. Solar PV installation on offices is an additional low-impact short-term lever.

• Fleet electrification towards 100% electric vehicles by 2030

  Transitioning the company fleet to electric vehicles is identified as the highest-impact single lever for scope 1 reduction. By end of 2024, 35% of company-owned vehicles were electric (up from 23% in 2023). Full transition is expected to reduce fleet emissions by approximately 6,400 tCO2e, representing ~71% of combined scope 1 and scope 2 (market-based) emissions. The target is full fleet electrification by 2030, with EV charging infrastructure availability considered in leasing decisions.

• Natural gas phase-out and office energy efficiency

  Arcadis is transitioning from natural gas to electricity or biogas for heating wherever possible. This lever is estimated to reduce emissions by approximately 2,200 tCO2e (~25% of combined S1+S2 market-based). Measures include incorporating sustainability clauses in leases, preferring LEED/BREEAM-certified offices, office consolidation, hybrid working to reduce office space, and installing solar PV where feasible. Energy consumption in 2024 was 69,400 MWh total, of which 41% from renewable sources.

• Business travel reduction through 'virtual first' travel policy

  Since May 2021, Arcadis operates a 'virtual first' travel policy requiring employees to default to virtual meetings. Carbon travel budgets were implemented for each business unit in 2024, aligned with a target to reduce business travel by 35% by 2025. The company also consolidated to a single travel management provider with carbon emissions reporting. Business travel (Cat 6) represents 11.3% of total GHG footprint at 32,300 tCO2e in 2024. Personalised quarterly traveller emissions updates and remote site visit technology (drones, 360° imagery) are further levers.

• Business travel reduction via carbon travel budgets

  In 2024, Arcadis implemented carbon travel budgets for each business unit, targeting 35% reduction in business travel GHG emissions and 50% reduction in air travel emissions by 2025. Switched to a single global Travel Management Company with online tools providing carbon information and greener-choice nudges. Updated travel policy in 2022 to prioritize virtual meetings, objective-stacking trips, and guidance on rail vs. air.

• Business travel reduction via mandatory travel booking platform and carbon budgets

  Business travel (S3 Cat 6) is a major Scope 3 lever at 29,000 tCO2e in 2023, down from 46,000 tCO2e in the 2019 base year. In 2023 Arcadis moved to a globally mandatory travel provider (feeding data to Thrust Carbon for emissions calculation), covering ~90% of travel data. Carbon budgets for business travel are being introduced in 2024. Local initiatives such as promoting cycling in the Netherlands and reducing plane travel frequency in the Philippines (65% reduction) further reduce travel emissions. The SBTi base year target requires 45% reduction in absolute S3 by 2029.

• Fleet electrification by 2030

  Arcadis is transitioning its leased vehicle fleet to electric vehicles by 2030. As of 2023, approximately 23-26% of the fleet has been transitioned to electric vehicles. This is identified as a high-impact, medium/short-term Scope 1 reduction lever.

• Office consolidation, hybrid working and electrified heating

  Arcadis is leveraging hybrid working in combination with office space reduction at multiple locations to reduce stationary energy. As office relocations and consolidations occur, transition from non-electric heated buildings to electric heating wherever possible. Workplace energy efficiency efforts aim to reduce electricity consumption per employee. Offices near public transit offer limited or no parking.

• Employee commuting — cycling, transit cards, mobility weeks

  Encourages cycling to work where realistic (saving ~17.6 tCO2 and 224.28 GJ in Netherlands in 2022). Provides public transit cards/allowances in some geographies (e.g., NS Business Card in Netherlands under new WERK-regeling mobility policy). Hosts mobility-week awareness campaigns globally. Limited office parking near public transit. Working-from-home electricity covered by renewable certificates.

• Electric vehicle fleet transition targeting 100% by 2030

  Fleet vehicle emissions represent the largest component of Arcadis' Scope 1 footprint (6,783 tCO2e from business/commuter travel by company vehicles in 2023). Arcadis has set a target to transition 100% of its company fleet to electric vehicles by 2030, with 23% achieved as of 2023. The EV transition delivered ~895 tCO2e of S1 reductions in 2023. Arcadis works with fleet managers and people directors in each country; fleet electrification is also partly captured under EU Taxonomy-aligned CapEx (6% of total CapEx in 2023 for low-emission vehicles).

• Office energy reduction and transition to all-electric buildings

  Arcadis' Scope 1 stationary energy (natural gas heating) and Scope 2 electricity together represent the primary operational floor of emissions. As leases expire, Arcadis evaluates moving to all-electric offices wherever feasible, and considers making all-electric offices a requirement for new leases under its workplace policy. In 2023, office downsizing and work-from-home policies reduced office-related emissions by ~1,400 tCO2e. Arcadis has also piloted energy efficiency programmes such as implementing electricity-saving guides and reducing office floor space, with example savings of 6.4 tCO2e in Romania via floor space reduction.

• Business travel reduction — 35% cut in Scope 3 travel emissions by 2025 vs 2019

  Business travel (Scope 3 Cat 6) is Arcadis' largest direct operational emission source. From a 2019 baseline of 42,820 tCO2e, Arcadis targets a 35% reduction and a 50% cut in domestic/international flights by 2025. In 2022 travel emissions rose to 21,410 tCO2e but remain 50% below the 2019 baseline intensity per FTE. Data is collected by Thrust Carbon directly from travel agencies and covers private vehicles, air travel, public transport, rental vehicles and taxis. Arcadis also participates in KLM's Corporate Biofuel program since 2017.

• Fleet electrification – transitioning company vehicle fleet to EVs by 2030

  Arcadis targets 100% low-carbon vehicles in its company fleet by 2030 (vs 0% in 2019 base; 11% achieved by 2022). In the Netherlands, EVs are now the default choice under the new WERK-regeling mobility policy (October 2022) and lease contract duration was shortened from 5 to 3 years to accelerate turnover. Arcadis is a signatory to the Anders Reizen Coalition fossil-free fleet pledge by 2025. In 2022, >55% of Dutch carbon emissions still came from fossil-fuel lease cars, making fleet electrification the primary near-term Scope 1 lever. Delivery has been delayed by EV supply chain disruptions in Europe.

• Employee commuting and working-from-home emissions reduction

  Arcadis includes both employee commuting and working-from-home (WFH) emissions in its Scope 3 inventory and SBT Int2 target. WFH emissions (10,070 tCO2e in 2022) are calculated using Ecometrica country-specific homeworker factors. Commuting (4,856 tCO2e) is estimated via employee surveys on distance and mode. Initiatives include cycling incentives (Fynch app rewards, 17.6 tCO2e saved in Netherlands), NS Business Card extension for private rail use, public transport promotion, and office locations near train stations. The combined Scope 3 commuting+WFH intensity of 0.55 tCO2e/FTE in 2022 is slightly above the 0.53 tCO2e/FTE 2019 baseline, making this a key area of ongoing focus.

• Office energy efficiency and footprint reduction

  Arcadis reduces Scope 1 stationary energy (gas heating) and Scope 2 electricity through office lease rationalisation, awareness campaigns, and efficiency upgrades (insulation, HVAC, LED lighting). A specific initiative in China involves promoting working from home alongside office space reduction, saving 18.4 tCO2e in Scope 2 in 2022. Spain and Portugal offices reduced electricity consumption per employee despite headcount growth, saving 0.2 tCO2e. Offices are located next to train stations where possible to reduce commuting and travel emissions. In 18 of 23 countries (78%), Arcadis holds ISO 14001 certification and dedicated budget for EMS maintenance.

• Office energy reduction and hybrid working to cut Scope 1, 2 and commuting emissions

  Arcadis reduces its Scope 1 and 2 footprint through the Global Environmental Management System Standard, requiring all entities to track energy consumption and pursue reduction roadmaps. 68% of entities hold ISO 14001 certified EMS. The 2021 Global Workstyle Promise institutionalised hybrid working across all offices, reducing both commuting (Scope 3 Cat 7) and office energy. A global real estate optimization program is also underway, reducing the physical footprint post-pandemic.

• Fleet electrification — transition all company vehicles to electric by 2030

  Arcadis has committed to transition its entire company fleet to electric vehicles by 2030. For the first time in 2022, renewable electricity certificates were sourced to cover the electricity consumption of company-owned/leased electric vehicles and employee private EVs used for business travel and commuting, effectively zeroing out the emissions from this category under the market-based accounting method.

• Business travel reduction via 'virtual first' travel policy

  In May 2021 Arcadis implemented a 'virtual first' travel policy requiring employees to start from the assumption all meetings will be virtual and justify any in-person travel. Flights under 700 km to destinations reachable by train are restricted. Air travel policies were tightened further in 2022 (video-conferencing preference, no creative ticketing, quickest not cheapest flights). In 2022, flight emissions intensity was 0.48 tCO2e/FTE vs 1.07 tCO2e/FTE in 2019 – a 55% reduction, exceeding the Int3 target of -50% by 2025. Absolute business travel emissions (22,720 tCO2e) remain ~50% below 2019 levels despite travel restrictions lifting. SAF purchases via the KLM-Air France programme saved 79 tCO2e in 2022 (Dutch flights only).

• Business travel reduction via 'virtual first' travel policy

  In May 2021 Arcadis implemented a global 'virtual first' travel policy, instructing all employees to assume meetings will be virtual and to justify in-person travel. This built on COVID-era learnings and targets a 50% reduction in flight emissions per FTE by 2025 (Int3, already achieved at 81% reduction in 2021). Short-haul flights under 700 km to train-accessible destinations are restricted, and biofuel partnerships with KLM/SkyNRG (since 2017) reduce flight emissions (28.6 tCO2e saved in 2021). Business travel (cat 6) represents the largest single S3 category at 12,613 tCO2e in 2021 versus 42,815 tCO2e in 2019.

• Employee commuting and work-from-home emissions reduction

  Employee commuting (11,003 tCO2e in 2019 baseline) and working from home (2,967 tCO2e in 2019; 13,891 tCO2e in 2021 due to pandemic) are included in the SBTi Int2 target (74% reduction per FTE by 2035). Arcadis encourages cycling to offices (Fynch app with cycling rewards in NL), promotes public transport and locates offices near train stations. Flexible working arrangements reduce overall commuting frequency. In 2021, commuting emissions per FTE were 33% of 2019 levels, putting the target 90% achieved.

• Office energy efficiency and green electricity for leased office portfolio

  Arcadis manages its office energy footprint through its global Environmental Management System (EMS, ISO 14001) implemented across 350+ offices. Measures include activity-based working (ABW) with hot-desking to maximise occupancy and minimise space, flexible working programmes, and selection of office locations near public transport. Stationary energy (gas for heating) accounts for 1,262 tCO2e of S1 and offices consume 22,318 MWh of electricity. The Dutch offices have solar PV panels generating 157,950 kWh (Den Bosch) and green electricity contracts covering 100% of Netherlands consumption.

• Fleet electrification targeting 100% low-carbon vehicles by 2030

  Arcadis set a target (Oth2) to transition 100% of its company-owned and long-term leased vehicle fleet to low-carbon (primarily electric) vehicles by 2030, from a 0% base in 2019; 11% was achieved by 2021. The company partners with the Anders Reizen Coalition committing to a fossil-free fleet by 2025. Electric vehicle orders increased in 2021, saving approximately 50 tCO2e in the Netherlands alone. Company-owned vehicle travel is the largest Scope 1 activity at 6,410 tCO2e out of 7,672 tCO2e total S1.

• Business travel reduction — policy, EVs, and sustainable aviation fuel

  Business travel (Scope 3 Cat 6) is Arcadis' largest single emission source at 12,372.5 tCO2e in 2020, representing approximately 75% of the total reported footprint including Scope 3. Key levers include: (1) electric vehicle fleet policy — EVs added to company car selection since 2015, reducing footprint by ~132 tCO2e in 2020; (2) tightened car eligibility criteria (minimum 17,500 km/year) reducing fleet size; (3) sustainable aviation fuel investment via KLM/SkyNRG since 2017 (21 megatonne biofuel purchased in 2020, saving 49.8 tCO2e); (4) an internal carbon price of €13/tCO2e used as a shadow price to guide travel decisions. COVID-19 caused >50% reduction in flights and public transportation in 2020.

• Employee commuting reduction through flexible working

  Employee commuting (Scope 3 Cat 7) totalled 10,764 tCO2e in 2020. Arcadis has implemented flexible working arrangements across most OpCos, enabling employees to work from home. The Global EMS is being extended to collect more specific and consistent commuter travel data globally. Currently only 48% of commuting data is from supplier/value-chain partners. The company notes that promoting working from home increases home electricity usage (classified as Scope 3), creating a trade-off. ABW programmes reduce office footprint needs.

• Office energy efficiency and EMS implementation

  Arcadis operates 20+ ISO 14001 certified EMS programs locally and is implementing an enterprise-wide Global Environmental Management System Standard (EMSS) to standardise data collection and drive energy efficiency improvements. Office energy (Scope 1 natural gas and Scope 2 electricity) is managed through Activity Based Work (ABW) programmes with open-plan hot-desking to minimise occupied floor area and energy use. Arcadis seeks a 4.2% annual reduction in Scope 1+2 emissions. COVID-19 related office closures contributed to an estimated ~5.6% additional Scope 1+2 reduction in 2020.

• Business travel reduction via policy change and sustainable aviation fuel

  Business travel is the most significant source of emissions (~75% of total GHG footprint including Scope 3). Arcadis changed its travel policy so that flights under 700 km that can be replaced by train default to train booking (~110 tCO2e saving). Since 2017, Dutch operations purchase sustainable aviation biofuel from KLM/SkyNRG (102.6 tonnes in 2019, ~240 tCO2e reduction). An internal carbon price of €13/tCO2e is used to justify such investments. The company is evaluating SBTi-approved Scope 3 targets that would formalize business travel reduction commitments.

• Office energy efficiency and lease selection for lower Scope 1 and 2 emissions

  Arcadis reduces office energy consumption through Activity Based Work (ABW) programs with open floor plans and hot-desking, flexible working arrangements, and strategic selection of greener buildings when signing or renewing leases. Regions actively invest in energy-efficient office upgrades. The global EMS (being implemented 2019–2021) will centralize tracking of energy consumption across 400+ offices globally, enabling systematic identification and pursuit of efficiency measures.

• Global EMS deployment to improve GHG data quality and drive continuous improvement

  Arcadis operates 20+ ISO 14001 certified EMS programs regionally and in 2019 committed to a global enterprise-wide EMS. The EMS will standardise emissions measurement across 30+ countries, replace worst-case scenario assumptions with measured data (improving accuracy ~10%), and embed systematic reduction programs. Set 2019 as the new global baseline. The EMS also underpins the SBTi evaluation for Scope 1, 2 and potentially Scope 3 targets, and supports ISO 14001 certification required by key clients.

• Company fleet electrification and fuel efficiency improvement

  Arcadis reduces Scope 1 fleet emissions by tightening company car eligibility criteria (raising minimum annual mileage from 15,000 to 17,500 km, saving ~140 tCO2e), replacing vehicles with fuel-efficient models (~8 tCO2e), adding electric vehicles to the selection menu (~91 tCO2e saved), and providing shared low-carbon vehicles (~33.5 tCO2e). Total fleet initiative savings were ~270 tCO2e in 2019, with monetary savings of €165,000/year.

• Sustainable procurement programme to reduce Scope 3 Cat 1 purchased goods and services

  Scope 3 purchased goods and services (Category 1) represent the largest portion of Arcadis' carbon footprint at 231,500 tCO2e in 2025. Arcadis is expanding its Sustainable Procurement Programme with an impact-driven approach: key suppliers are invited to disclose emissions through CDP, smaller partners receive tailored support via an automated reporting tool, and internal capability is built through net-zero supply chain training and hotspot analyses. ESG contractual clauses embedding health, safety, human rights and environmental performance requirements were developed in 2025 for integration into supplier contract templates. Operational effectiveness across the value chain is targeted by 2027.

• Carbon Impact initiative: whole-of-life carbon assessment for client projects

  As part of Arcadis Future IMPACT+, the Carbon Impact initiative operationalises Arcadis' November 2023 commitment to assess the whole-of-life carbon impact of key projects and deliver carbon savings for clients. Pilot projects have demonstrated that life-cycle carbon assessment can unlock 30–47% emission reductions when low-carbon design alternatives are adopted. The initiative addresses the primary climate transition risk (rising costs of Scope 3 Cat 1 emissions) and supports upcoming CSRD phase-in requirements for value chain impact reporting by 2027. 2026 projects tracked via the Arcadis Future IMPACT+ platform.

• Supply chain engagement to reduce purchased goods & services emissions

  Purchased goods and services (Cat 1) is by far the largest emission source at 78.6% of total footprint (223,400 tCO2e in 2024). Arcadis joined a third-party supply chain management platform (CDP Supply Chain) in 2023 and expanded supplier coverage in 2024, now collecting emissions data from 70 of its largest suppliers covering ~10% of spend-based emissions. The Sustainable Procurement Program is being professionalised with category management strategies targeting higher-emitting categories. A Supplier Code of Conduct requires suppliers to report and reduce emissions.

• Sustainable project choices and whole-life carbon in client delivery

  Arcadis integrates carbon footprint assessments into major project pursuits and has launched 'Project Carbon' to measure whole-of-life carbon on new major projects. The Net Zero Catalyst digital tool (launched end of 2024) helps clients set and execute net zero roadmaps. The Energy Transition Academy trains 2,500+ Arcadians by 2027 to support client decarbonisation. Arcadis aims to embed sustainability lenses (energy & carbon, circularity, nature, water, societal impact) into all client engagements, with sustainable project choices as one of three strategic pillars of the 2024-2026 strategy.

• Supplier engagement on purchased goods & services

  Purchased goods & services is the largest emissions category (~181,000 tCO2e in 2023, ~73% of Scope 3). Arcadis is future-proofing procurement, developing category management strategies for higher-emitting categories, and engaged the CDP Supply Chain program to encourage suppliers to report emissions and collaborate on emissions reduction and net-zero targets.

• Growing Sustainability Advisory and Energy Transition client services as revenue-linked decarb lever

  Arcadis' strategy explicitly links commercial growth to client decarbonisation, framing its sustainability advisory, energy transition consulting, net-zero building design, climate adaptation, and rail infrastructure services as both a commercial opportunity and an indirect Scope 3 avoided-emissions lever. EU Taxonomy-aligned turnover reached 13% (EUR 649M) in 2023 across rail infrastructure (8.7%), MEP/energy performance services (2.3%), and climate adaptation engineering (1.9%). The firm is growing its Sustainability Advisory and Energy Transition practices globally. While avoided emissions are not formally quantified at the corporate level, select project-level quantification began in 2023.

• Supply chain engagement via CDP Supply Chain programme to reduce S3 Cat 1 purchased goods emissions

  Purchased goods and services (S3 Cat 1) is the largest single Scope 3 category at 181,000 tCO2e in 2023 (vs 218,000 tCO2e in 2019 base). Arcadis joined CDP Supply Chain for the first time in 2023, inviting 126 suppliers (by spend and emissions intensity) with a 57% response rate; supplier primary data now covers ~10% of Cat 1 calculations. Category management strategies are being developed to inform decision-making by category. Key levers per category include supplier industry decarbonisation, selecting low-emissions suppliers, and innovative technologies. Arcadis' Sustainable Procurement Programme includes ESG risk matrices, a Supplier Code of Conduct, and Prewave-based monitoring covering ~70% of supply base continuously.

• Client decarbonisation solutions — embedding net zero into project delivery (Project Carbon initiative)

  In 2022 Arcadis launched the 'Project Carbon' initiative to embed carbon impact measurement into all building and infrastructure projects, systematically identifying and implementing decarbonisation opportunities. The five Arcadis Sustainability Themes (Energy & Carbon, Climate Adaptation, Circularity, Nature & Biodiversity, Societal Impact) are being integrated into service delivery. Arcadis' global Sustainability Advisory practice (200+ experts) and Energy Transition practice (360+ experts) directly serve clients seeking net zero pathways, with dedicated Go/No-Go criteria ensuring Paris-aligned client selection.

• Supplier engagement and Scope 3 Cat 1 reduction programme

  In 2022 Arcadis conducted a cross-industry Supplier Sustainability Collaboration Pilot and in January 2023 joined CDP Supply Chain, inviting 126 major suppliers (by spend) to disclose to CDP. The Scope 3 Cat 1 (Purchased goods & services) footprint of 458,200 tCO2e in 2022 is the dominant Scope 3 category and was calculated for the first time using spend-based methods. A Supplier Collaboration programme to reduce Scope 3 impact through the supply base is under development, following ISO20400 sustainable procurement guidelines. Climate-related requirements for suppliers are planned for introduction within two years.

• Purchased goods and services (Scope 3 Cat 1) supplier collaboration program

  Scope 3 Category 1 (Purchased Goods & Services) accounts for 91% of total Scope 3 at 458,200 tCO2e and is by far the largest category. Arcadis reported this for the first time in 2022 using spend-based EEIO methodology. A Supplier Collaboration program on Scope 3 reduction is being developed. A refreshed Supplier Code of Conduct including ESG expectations is in place, alongside a pre-qualification questionnaire with human rights and sustainability questions.

• Supplier engagement on travel and sustainable aviation fuels

  Arcadis engages key travel suppliers to reduce supply-chain emissions, particularly airlines. Since 2017 it has purchased sustainable aviation fuel (SAF) through KLM/SkyNRG (1.7 megaton biofuel purchased in 2021, realising 4.03 tCO2e footprint reduction, plus 28.6 tCO2e saved via biofuel uplift). A 'Supplier Sustainability Collaboration Pilot' extends engagement to IT (data centres), construction, and laboratory suppliers, explicitly capturing GHG emissions data. Arcadis plans to introduce climate-related supplier requirements within the next two years.

• Scope 3 supply chain engagement — SBTi target development including Scope 3

  As part of its 2020 SBTi pledge, Arcadis is developing Scope 3 targets covering material upstream categories. In 2020, it reviewed lessons from prior Dutch scope 3 analysis to develop a global approach, initiated in 2021. Supplier engagement focuses on travel service providers (e.g. Concur) covering ~65% of supplier-related Scope 3 emissions, representing 10% of suppliers by number. Arcadis is updating its global materiality assessment for all 15 Scope 3 categories (results due Q3 2021) and deploying a Global Non-Financial Reporting system in 2021 to improve data granularity.

• Carbon offsetting program to achieve 2030 zero-carbon goal

  Arcadis purchases high-quality carbon offsets to neutralise residual emissions while pursuing reductions. In 2019, 4,697 tCO2e of Gold Standard credits were purchased (cookstoves in India via FairClimateFund, forest protection in Singapore, energy-efficient ovens in Belgium). As of 2020, a global portfolio of six offset projects will cover all global operations. The internal carbon price (€13/tCO2e shadow price) is used to evaluate offset investments. Offsets are a bridging mechanism while SBTi-aligned reductions are pursued.
