SUSTAINABILITY AT BGC Sustainability at BGC is not only about understanding our own environmental footprint, it is about equipping the people we work with to make better, risk-informed decisions that protect health and safety, strengthen communities, and support longterm infrastructure resilience. Our role is to bring technical expertise and practical solutions that help clients navigate complex challenges and adapt responsibly to a changing world.

Internally, our approach to sustainability is focused on embedding environmental, social, and governance (ESG) considerations into our business operations. This includes strengthening governance, developing systems for ESG-related data collection and reporting, creating programs and policies that protect the health and wellbeing of our employees, and engaging people across the organization in shaping our approach.

BGC Engineering Sustainability Report 2025

In 2025, we strengthened our ESG reporting by establishing a Sustainability Report Steering Committee, composed of senior leaders and a member of our Board of Directors (BOD). Operating within BGC’s broader risk governance structure, the committee provides strategic oversight and coordinates cross-functional sustainability priorities. It complements BGC’s established day-to-day risk management functions such as our Technical and Corporate Risk groups and our Health and Safety Team, which continue to identify, assess, and manage operational risks across the organization.

Together, these groups support a cohesive approach to risk management under the direction of the BOD and Management Team (MT).

GREENHOUSE GAS ACCOUNTING AND CARBON OFFSETS We have tracked our greenhouse gas (GHG) emissions annually since 2017 using the GHG Protocol Corporate Standard (WRI and WBCSD, 2004). Our inventory includes Scope 3 emissions from electricity and heating, business travel, commuting, shipping, paper use, and IT hardware.

Between 2022 and 2024, total emissions increased as in-person collaboration, office use, and business travel rebounded post-pandemic. As our team continues to grow and we require larger office spaces, wherever possible, we seek out workspaces with more efficient HVAC systems so our team growth does not have an equal impact on our emissions.

Importantly, emissions per employee remain below pre-pandemic levels, reflecting improved operational efficiency.

In 2023, tracked emissions from hardware are higher due to a more comprehensive dataset: previous years included only laptops and monitors, whereas the 2023 and 2024 inventories incorporated all IT equipment—such as workstations, servers, and phones—based on detailed spending records. These emissions are captured in the “Other” category in the charts below.

Since 2018, we have purchased carbon offsets for emissions from

our Annual General Meeting (AGM) events (excluding 2020, which was held virtually). Since our last report, this includes offsets for two AGMs: for the 2023 AGM, 561 tCO2e were retired through eight Gold Standard–certified projects, and for the 2024 AGM, 515 tCO2e were retired through a similar diversified portfolio.

Looking ahead, we plan to strengthen our GHG accounting by evaluating additional Scope 3 categories, including cloud computing and software use. We also plan to expand offsetting beyond our AGM to include travel associated with our social impact program, BGC Squared.

EVENT HIGHLIGHT

Post-Helene Lidar Change Detection Client: Pro bono Location: North Carolina, USA After Hurricane Helene struck in September 2024, Cambio Earth demonstrated a rapid, data-driven model for post-disaster recovery. Within six weeks of the storm’s landfall, BGC and partners secured airborne lidar surveys over two isolated North Carolina communities and completed change-detection processing for a vast area (approximately 240 km2) in only five days.

The results, shared openly with 75 users across 15 agencies, provided safe-access routing, objective damage metrics, and a reliable baseline for reconstruction.

Sustainability is built into the approach through speed, openness, and accessibility. Traditional field surveys can take months, but this standardized workflow compresses decision timelines to days.

BGC Engineering Sustainability Report 2025

This enables responders to act swiftly and reduce cascading risks to people and infrastructure. Highresolution change models revealed landslides, scour, and channel migration, helping engineers size culverts, stabilize slopes, and adapt maintenance for intensifying climate hazards.

Beyond technical outcomes, the data availability through Cambio broadened access for local responders and university partners, creating shared capacity for risk-informed rebuilding.

This replicable blueprint (pre-event contracts, rapid acquisition, and transparent release) supports climate resilience while empowering communities to adapt and recover more effectively from climate-driven disasters.

PROJECT HIGHLIGHT

Landslide Mapping using AI for Resilient Communities and Infrastructure Client: BGC and Cambio Earth Location: USA and Canada (pilot regions) This project leverages artificial intelligence to better equip communities and infrastructure operators in responding to or understanding climatedriven geohazards. Lidar change detection data are currently a cornerstone of geohazard identification and characterization, whether in rapid response mode or part of a longer-term monitoring plan. However, the manual review process of lidar change detection data is still time consuming and fraught with nuance.

BGC has developed a machine-learning pipeline that applies object detection and segmentation models—originally designed for fields such as medical imaging and autonomous vehicles— to post-event lidar and lidar change-detection data. This approach enables landslides that occurred between lidar acquisitions to be mapped within hours rather than weeks or months. Early versions of the model already exceed human performance in terms of mapping completeness.

2025 CIO AWARD FOR INNOVATION:

In 2025, BGC and Cambio Earth received the CIO Award for AI Innovation in Geohazard Monitoring, recognizing our partnership in advancing earth science intelligence. The award highlights how we combine leading geoscience expertise with responsible, explainable AI to deliver faster, clearer insights for clients facing increasing natural hazard risks.

By transforming complex datasets such as lidar and InSAR into timely, actionable information, our joint work strengthens—rather than replaces—human judgment in critical decision-making. This recognition reflects the power of science-led innovation in supporting safer, more resilient infrastructure and communities.

This rapid, automated process provides communities and infrastructure operators with high-resolution landslide maps that integrate seamlessly into geospatial workflows. By scaling mapping capacity and addressing the subjectivity inherent in manual geohazard mapping, the project enables more complete and timely inventories. These inventories are critical for understanding geohazard potential, assessing climate controls on hazard occurrence, and supporting proactive risk management, early warning systems, and climate-resilient planning.

PROJECT HIGHLIGHT

Searching for drinking water solutions in Amazonas Client: CADENA Colombia (NGO) Location: Amazonas, Colombia In early 2025, four BGC employees travelled to the Amazonas region of Colombia, partnering with Bogotábased NGO CADENA Colombia. The team’s goal was to explore sustainable drinking water solutions for six remote communities affected by severe drought.

“Your technical expertise, professionalism, and commitment have provided us with critical knowledge that goes far beyond data: it represents hope and concrete possibilities for Indigenous communities facing increasing challenges in access to safe water.”

Letter excerpt, Sol Bentolila Cohen, President, CADENA Colombia

BGC Engineering Sustainability Report 2025

Rivers that once sustained daily life had nearly dried up, leaving communities struggling to collect enough rainwater to meet basic needs. To help, our team conducted a groundwater reconnaissance program using electrical resistivity tomography (ERT) to identify sand and gravel layers suitable for freshwater wells.

The team also sampled existing water sources to assess quality and guide future filtration and protection strategies, particularly from artisanal mining impacts.

The findings will help CADENA Colombia apply for grants to implement new water systems, improving access to safe drinking water for six isolated communities. Beyond the technical results, the project strengthened partnerships, blended Western science with Traditional Knowledge, and reinforced BGC’s belief that meaningful change starts with connection, collaboration, and compassion.

GENDER PAY EQUITY We are committed to fair and equitable compensation as part of our broader focus on EDI. Every year, we conduct a gender pay equity analysis to assess whether compensation is fair, transparent, and consistent across our workforce. Our 2025 analysis (based on 2024 calendar year compensation data) and our 2024 analysis (based on 2023 calendar year compensation data) show that there continues to be no statistically detectable pay gap between men and women at BGC when considering role and job class, geography, and performance.

Our analysis includes base salary, bonuses, and longterm incentives, and applies statistical methods aligned with industry best practice. While our current reporting reflects binary gender categories due to data limitations, we are committed to expanding our analysis in future years to better reflect the full diversity of employees as demographics data allows. In 2025, women represented 37% of the BGC workforce, down from 39% in 2024, and made up 36% of our shareholder population, an increase from 35% in 2024. These figures align with overall gender demographics across shareholder-eligible roles.

In alignment with our ESG commitments and legal obligations, BGC meets pay transparency reporting requirements in the jurisdictions where we operate, including the province of British Columbia (B.C.). BGC now includes salary ranges in all Canadian- and U.S.-based job postings, and published an annual B.C. Pay Transparency Report in 2025.

Annual Safety Reporting Contest BGC’s Annual Safety Reporting Contest encourages proactive safety reports and site inspections to help us better understand workplace hazards, strengthen safe work practices, and support a culture of shared responsibility.

Best Hazard Recognition Category 2025 Winner A BGC team member recognized an emerging ergonomic hazard while performing routine groundwater sampling and took timely action that prevented a potential injury. During the day, the team member noticed increasing lower back stiffness while sampling a newly installed deep groundwater well. Although some stiffness was expected following a recent on-site fitness class, the physical demands of the task—manually pulling multiple litres of water from a 125-metre-deep well using a bailer and reel—caused the discomfort to worsen.

After several repetitions, the team member assessed that continuing the work could lead to injury. They made the safe decision to stop work and requested assistance from on-site client personnel to complete the remaining tasks. This proactive response ensured the work was completed safely while protecting personal health. The team member also discussed the challenges of the unique well setup and their limited experience with it, helping identify contributing factors such as equipment features that increased physical effort.

As a positive outcome, arrangements were made to use an electric winch for future sampling, significantly reducing physical strain.

The team member also sought immediate support from the onsite physiotherapist, reinforcing a strong safety culture centered on early hazard recognition, communication, and prevention.

GOVERNANCE

INTRO | ENVIRONMENT | SOCIAL | GOVERNANCE OUR APPROACH TO GOVERNANCE Governance at BGC is grounded in many of the same principles that guide our technical work: responsibility, collaboration, and transparency. As a privately held, 100% employee-owned company, we operate with a flat and participatory governance structure. Over half of our employees are shareholders (53%), and almost all senior and principal engineering and geoscience staff are shareholders.

Ownership carries both rights and accountability. This model fosters a long-term perspective that prioritizes integrity, safety, and the sustainability of our company, our people, and the communities we serve.

OVERSIGHT AND RISK MANAGEMENT BGC’s BOD provides oversight of strategic, financial, operational, environmental, social, and governance risks.

Directors are elected annually by shareholders. As outlined in its Terms of Reference, the BOD is accountable to shareholders and works closely with the Chief Executive Officer and Management Team to make decisions that are informed, balanced, and aligned with our purpose.

The BOD meets with the Management Team at least monthly, in addition to attending four quarterly board meetings, a midyear and year-end shareholder meeting, and other meetings as required.

Our governance framework integrates risk management across all areas of operation. Risk management is not viewed as a constraint, but as a foundation for responsible decision-making.

It enables us to make significant internal investments in areas such as training and research and development, and to deliver resilient, high-quality work while maintaining the trust of clients, partners, and communities.

ETHICS AND INTEGRITY Ethical conduct is a non-negotiable standard at BGC. Our Code of Conduct defines expectations for integrity, professionalism, and respect, and applies to all employees, contractors, and partners. It supports fairness and compliance with laws, professional standards, and human rights principles. As a firm of licensed professionals, we also align our internal practices with the ethical obligations established by the professional bodies that certify many of our team members.

BGC’s Privacy Policy outlines our responsibility to safeguard personal information and ensure that data is collected, used, and stored in a manner that respects individual rights and complies with applicable legislation. Our Respectful Workplace Policy further reinforces our commitment to a safe and inclusive environment by setting clear expectations for professional conduct and providing confidential processes for addressing bullying, harassment, or discrimination.

INTRO | ENVIRONMENT | SOCIAL | GOVERNANCE CYBERSECURITY AND DATA PROTECTION Safeguarding client and company information is a critical aspect of good governance. BGC’s Cybersecurity Policy outlines standards for responsible data management, access control, and threat mitigation. Regular employee training, multi-factor authentication, and encryption protocols help ensure information security across all of BGC’s operations.

Cybersecurity performance and risk management are subject to BOD oversight.

In 2025, Cambio Earth achieved ISO 27001 certification, an important milestone for the organization and clear evidence of our commitment to cybersecurity.

LEADERSHIP AND DIVERSITY Strong governance depends on diverse perspectives and inclusive leadership. As of 2025, 29% of BGC’s BOD and 43% of the Management Team are women. Beyond gender representation, the BOD reflects diversity of thought through representation across the geographies in which we operate and across all major practice areas.

This breadth of experience helps the BOD understand industry challenges on the ground and identify opportunities to lead in delivering resilient, risk-informed solutions for our clients and the communities we serve. Directors and many Management Team members also bring a wide range of business and technical backgrounds, adding valuable depth to decision-making.

The BOD reviews diversity, equity, and inclusion progress annually to support equitable access to leadership, mentorship, and career development.

Looking Ahead

2026 & BEYOND As we look to the future, our focus remains on advancing the science, relationships, and practices that support sustainable and resilient outcomes for the communities, clients, and environments we serve. We will continue to integrate climate intelligence, earth and environmental science, and risk-informed decision-making across our work, with a growing emphasis on water security, climate adaptation, and community resilience.

We will also continue to strengthen the internal systems that support transparency, ethical practice, and a safe, inclusive workplace. This includes ongoing investment in training, professional development, and opportunities that foster diversity of thought and equitable career pathways. Our safety culture will remain a priority through proactive reporting, continuous learning, and collaborative problem-solving.

As we move into 2026 and the years ahead, we are committed to building on the foundations set out in this report and delivering science-based solutions and responsible stewardship for the benefit of people and the planet.
