Sustainability Summary
Message from Leadership
Ron Holmes, Vice President of Corporate Sustainability
This year marked a pivotal step in advancing sustainability as a core element of how Haskell operates, innovates and creates long-term value. Teams across the enterprise demonstrated a strong commitment to responsible growth, transparency and continuous improvement.
We strengthened our environmental performance by implementing more accurate greenhouse gas tracking and deploying IsoMetrix Lumina, improving data integrity and decision‑making. We also enhanced the quality and consistency of our disclosures to third‑party rating agencies, increasing the reliability of information shared with clients, team members and stakeholders.
Collaboration was central to our progress. Together with Human Resources, we developed key policies reinforcing ethical operations and governance. In partnership with Preconstruction and Legal, we established the Sustainable Procurement Policy and integrated the Supplier Sustainability Code of Conduct into contractual agreements, thus promoting accountability throughout our supply chain.
To support long-term success, we launched a cross-functional Sustainability Steering Committee and revitalized the Sustainability Council, aligning our
efforts with business objectives. These groups helped formalize Haskell’s Sustainability Vision, Mission and Purpose, providing unified direction for the organization.
We advanced risk preparedness by working with the Risk Management and Safety teams to develop the Climate Financial Risk Report, thereby strengthening our resilience to climate-related risks. In the field, we partnered with construction teams to lay the groundwork for consistent jobsite sustainability practices across all projects.
As I reflect on this year’s accomplishments, I am proud of the cross-functional leadership and teamwork that enabled them. Sustainability continues to shape the expectations of our clients, stakeholders, team members and communities. Through our collective efforts, Haskell is well-positioned not only to meet those expectations but also to lead.
Together, we can build a more sustainable world—one that embeds sustainability into every decision and discipline. I look forward to continuing this work and expanding our impact in the years ahead.

Materiality Assessment
In May 2025, Haskell’s Sustainability Steering Committee conducted a materiality assessment to identify key environmental, social and governance (ESG) priorities. The findings, approved by the Executive Leadership Team, serve as a strategic guide for aligning sustainability efforts with long-term business objectives.
The 2025 materiality assessment confirms that Haskell’s future is grounded in people, integrity, innovation and environmental stewardship. By aligning sustainability priorities with the issues most critical to our business and stakeholders, we reinforce a strong foundation for long‑term success.
Several themes emerged:
- People First: Employee satisfaction, workplace safety and inclusion remain top priorities.
- Trust & Integrity: Ethics, compliance and supply chain practices are essential to how we do business.
- Innovation & Resilience: Technology, infrastructure and security are critical to our future success.
- Environmental Impact: Energy, water and sustainable building practices continue to drive our environmental agenda.
- Community Engagement: Strong relationships with the communities we serve are highly valued.
Looking ahead, Haskell will:
- Integrate findings into overall business strategy
- Maintain strong transparency and accountability
- Foster ongoing collaboration with stakeholders
- Continue driving innovation for a sustainable future
- Strengthen employee engagement, satisfaction, and safety
- Safeguard trust by strengthening data security and resilience
Haskell’s Sustainability Pillars
Throughout the year, we have often been asked, “What is sustainability?” and “What does sustainability mean to Haskell?” To bring clarity, we developed the Haskell Sustainability Pillars, a structured framework that will guide our long‑term sustainability ambitions. By identifying our impacts and opportunities, the pillars help organize complex sustainability challenges into focused priority areas that align with our business strategy. Together, they form the foundation for setting measurable goals, directing resources, and ensuring consistent progress toward a more resilient and responsible future.
Commitment
Leverage advanced technologies and best practices to mitigate risks
Carbon
Decarbonize buildings and jobsites and enhance energy efficiency
Water
Optimize water use and reduce stormwater runoff impacts
Waste
Maximize landfill diversion, advance circular practices and strengthen material reuse
Employee Wellness
Ensure healthy, safe work environments for all employees
Materials
Source sustainable materials to minimize environmental impact
Haskell’s Emissions
2025 marked Haskell’s second year of calculating greenhouse gas emissions. Building on our 2023 baseline, we streamlined our data collection processes and accounting practices, resulting in more accurate and reliable emissions data.
One of the key improvements was the implementation of IsoMetrix, Lumina. Lumina is a cloud-based software solution designed to manage our greenhouse gas emissions inventory. The software is tailored to our industry and is scalable to support all of our office and jobsite locations.
As a reminder, Scope 1 covers direct greenhouse gas emission from company-owned sources such as fuel burned in vehicles, and onsite equipment. Scope 2 includes indirect emissions from purchased energy such as electricity, heating and cooling. Scope 3 accounts for all other indirect emissions across our value chain, including purchased goods and services, waste, business travel and products use.
Below is the breakdown of our Scope 1, Scope 2 and Scope 3 emissions representing our 2024 Greenhouse Gas Emissions.
Third Party Rating
Haskell participates in global sustainability disclosures and benchmarking platforms to evaluate performance and strengthen transparency. These assessments provide independent validation of our sustainability practices and help guide continuous improvement in our program.
CDP
CDP provides a platform for reporting environmental impacts across categories such as climate change, deforestation and water security. Submitted data is scored to reflect an organization’s level of transparency, awareness and climate-related risk.
Our 2025 CDP results showed strong progress, improving from a D (Disclosure) to a C (Awareness) in both Climate Change and Water Security.
EcoVadis
This evaluation measures the strength of our environmental, social and governance programs across four categories: Environmental, Labor & Human Rights, Ethics and Sustainable Procurement.
Using the gap analysis from our 2024 results, Haskell improved its performance and earned the EcoVadis Committed Badge by making meaningful progress in all four areas, supported by strong collaboration with our HR and Procurement teams.
Sustainable Building Practices Adoption Maturity Index
The Sustainable Building Practices Adoption Maturity Index (SAMI) is an evaluation of our sustainable jobsite practices. The assessment is conducted by AXA XL, our insurance company. The assessment benchmarks Haskell directly against other North American construction companies of similar size and operations; it also shows how we compare with all participating construction companies, regardless of size. The assessment uses the Contractor’s Commitment as a conceptual framework to evaluate factors within the control of builders and is composed of six categories: carbon, jobsite wellness, waste management, water management, materials and commitment. Each fall, AXA XL conducts a desktop review of our programs to evaluate our progress and provide a personalized report comparing our performance with current industry trends and peers.
SAMI has provided Haskell with a framework to create, grow and compare our sustainability efforts with the rest of the industry. In 2025, Haskell demonstrated significant improvement across all categories, doubling our overall score and achieving a “Good” rating in carbon and water management and a “Better” rating in commitment. We were
commended for our clear focus on developing our team and our tactics across the board. Through the Sustainable Building Practices Adoption Maturity Index, Haskell has the guidance necessary to build a better, more sustainable future.
