GSR Annual Report 2025 Planet Pillar

Our Path to Regeneration is the roadmap that guides how we reduce carbon emissions across our value chain, using a direct, data-driven approach and transparent tracking over time. Building on the progress we made last year, we continued strengthening the systems that help connect data across the business, from our offices and “living labs” to project delivery and operations.

Tracking is important because our 2030 goals require consistent measurement and follow-through, and it helps teams make informed decisions as expectations and conditions evolve. The updates that follow summarize progress in 2025 across a few key areas. 

Reducing waste is one of the most direct ways we can lower environmental impact and improve how work gets done, from procurement and material handling through closeout. In 2025, we continued to focus on practical waste reduction and diversion strategies that teams can apply on projects and in our operations, supported by clearer tracking and more consistent practices.  

On every project, we aim to reduce equipment-related emissions and minimize dust, noise and vibration. We use cleaner technologies, maintain equipment for efficient operation and implement controls to limit particulate matter and environmental nuisances, helping protect air quality, worker health and surrounding communities. 

Beyond power generators, hybrid and electric options have become the default for many other pieces of equipment, including hybrid light towers, PV security towers and electric scissor lifts. These strategies reduce emissions and directly support our decarbonization goals.   

DPR is committed to using water responsibly across our projects. We work to reduce potable water consumption, prevent pollution and protect surrounding habitats through proactive planning, efficient technologies and daily site practices that prioritize conservation and environmental protection. 

In 2025, we expanded water conservation, reclamation and reuse strategies across major projects, reinforcing our commitment to responsible resource management. Monthly water audits, supported by project-level tracking tools, created a consistent feedback loop that helped teams refine practices and reduce consumption over time. We documented over 48 million gallons of fresh water saved in the year.

On large projects, wheel-wash systems that recycle more than 95% of the water used are becoming standard practice, and our concrete washout reclamation systems collectively saved hundreds of thousands of gallons of fresh water each month.

At DPR, who we build is as important as what we build. Creating healthy workspaces is one way we live that belief. We are intentional about shaping environments that support the well-being of our people and allow them to do their best work. 

From how we design and build our offices, jobsites, and prefabrication facilities to how we operate them day to day, we prioritize health as a core part of our culture. By investing in spaces that support our teams, we reinforce our commitment to respect the individual and change the world. 

In 2025, we continued to advance this commitment through measurable actions and meaningful results. 

Our team reported a 2.5% increase in self-perceived performance increase in a WELL Platinum workplace, equating to approximately $150,000 in annual productivity impact at that location.

DPR’s self‑perform concrete group advanced its decarbonization efforts in 2025 by installing low-carbon concrete on projects across the U.S. The low-carbon concrete mixes used supplementary cementitious materials (SCMs) such as fly ash and slag. SCMs partially replace cement—the most carbon‑intensive component of concrete—resulting in a mix that reduces embodied carbon while maintaining the performance characteristics required for structural work. 

The volume installed in 2025 represents a notable increase over prior years, reflecting both rising owner demand and DPR's commitment to integrating lower‑carbon materials across self‑perform operations. This progress also establishes a foundation for continued innovation in concrete mix design as material technologies and owner requirements advance. 

DPR is committed to selecting and using products responsibly to reduce environmental impact. We prioritize materials with lower emissions, safer chemical profiles and verified sustainability attributes, ensuring that products are handled and installed in ways that protect people and the environment. 

We have maintained our commitment to materials transparency through engagement as a MindfulMATERIALS community partner. Our teams continue to educate clients on evaluating materials for selection with the Common Materials Framework (CMF) as part of a more comprehensive approach to sustainable materials. 

Looking ahead, we’re advancing this commitment through innovation. Most notably, in 2025, Digital Building Components (DBC) invested in developing a new Part B Product Category Rule (PCR) to close a gap in the industry and provide a credible pathway for multi-material exterior wall assemblies to obtain Environmental Product Declarations (EPDs).  

This effort has already resulted in first-of-their-kind product-specific EPDs for DBC’s EIFS and MCM wall panel systems with an IMP system EPD expected in Q2 2026. By delivering the first quantifiable carbon data for prefabricated exterior wall panel assemblies, DBC is raising transparency and performance expectations for the entire industry. We are working to prioritize materials that provide these data through online databases that allow our internal teams and partners to search supply chains more efficiently and identify healthier materials.  

DPR is committed to sourcing wood responsibly by prioritizing FSC‑certified and other independently verified sustainable wood products across all permanently installed applicatio520ns. We work closely with suppliers to ensure full Chain‑of‑Custody documentation and transparent sourcing practices that protect forests, support ethical forestry and meet our clients’ sustainability expectations.  

Industry participation and recognition help us stay connected to evolving expectations and emerging tools and help translate what we learn into practical action on projects. 

At Autodesk University 2025 in Nashville, we joined the Sustainability Cohort to collaborate with peers on carbon-aware, data-driven design and construction. The cohort explored tools such as Forma, Revit 2025, and the Insight engine, plus the Sustainability Data API, which connects third-party environmental datasets into BIM workflows. Later in the year at Greenbuild, we led a session with Autodesk focused on how the industry can adopt these technologies to support more informed and sustainable project decisions. Discussions focused on how automation and AI can support better decisions across the project lifecycle. 

2025 Cross-Industry Collaboration:

In 2025, we completed our first climate-related physical risk assessment across our office locations to understand how changing conditions could affect delivery, cost, schedule, supply chain and long-term resilience. Using EarthScan modeling across major office locations and representative project contexts, we evaluated exposure to heat, wind, flooding, drought, extreme precipitation and wildfire under multiple emissions scenarios. Results indicate increasing physical risk, with wind presenting near-term operational considerations and heat stress emerging as a longer-term risk, including high combined risk ratings by 2030 in regions such as California, Phoenix/Mesa, Amsterdam and Seoul.

We are integrating these insights into preconstruction and risk planning, scheduling, design recommendations and crew safety protocols, while also strengthening supply chain resilience. Our experience also helps us support customers as climate risk disclosure expectations evolve, including California SB 261 and the Task Force on Climate-related Financial Disclosures (TCFD) framework. 

REPRESENTATIVE PROJECTS

Louisiana Data Center

The Louisiana data center shows how fuel, water and waste practices can be integrated into daily site operations to reduce environmental impact while maintaining productivity. 
In 2025, the team advanced three efforts:

• The team shifted fleet fueling to R99 renewable diesel (HVO), with 100% of DPR GC and SPW equipment, excluding cranes, fueled with HVO.
• At the concrete batch plant, the team operated a closed-loop washout water reclamation system that captured, treated, and reused water from concrete operations, reducing freshwater demand and preventing contaminated discharge, with zero effluent-contaminated water discharged from the batch plant.
• The team also maintained consistent waste separation in office spaces to divert recyclable and compostable material from landfill.

• 98,000 gallons of R99 renewable diesel (HVO) used in three months
• ~2 million pounds CO2 reduced
• ~540,000 gallons of water saved and recycled over four months (concrete washout reclamation)
• 100+ cubic yards of recyclable and compostable materials diverted monthly (office waste separation)

As we look ahead, we will continue advancing sustainability by embedding it more deeply into how we plan and deliver work. Our focus remains practical and project-ready, with an emphasis on consistent application across the business and adaptability to project conditions.
