Environmental leadership at EPCO​​R

We empower our people to be leaders on environmen​t and public health by anticipating the future direction of regulation and legislation, being early adopters of technologies and improved operating practices, and acting as trusted advisors to policy makers.​​

​This culture of environmental leadership has led to EPCOR being recognized as: one of Canada’s Best 50 Corporate Citizens, an EnviroVista champion-level operator in Alberta, one of America’s Utilities of the Future Today, and a Canada’s Clean50 award winner for environmental sustainability.

EPCOR’s leadership is underpinned by its Health, Safety and Environment Policy​, which commits the company to “preventing pollution and reducing our environmental impacts, including those contributing to climate change and affecting the ecosystems in which we operate.” 

This commitment is backed by disciplined day-to-day operations, with most of EPCOR’s Canadian operations holding third-party ISO 14001:2015 certification for their environmental management systems. Through its Enterprise Risk Management program, the company identifies, manages and monitors business risks that could significantly impact day-to-day operations or its ability to achieve its long-term plans.​​

Scorecard at a ​​glance

Our performance measures, data and targets speak to the importance we place on protecting the environment. We have innovative programs and initiatives underway that are helping to reduce our environmental footpri​nt, protect critical infrastructure and support community resiliency and sustainability. We seek to exceed the minimum requirements for our industry, and are always looking for innovative ways to improve our approach.​​

​Net g​reenhouse ​​gas emissions​ (tCO2e)

​213,927 tonnes

​EPCOR owned and leased, company-wide Scope 1 and 2 emissions net of offsets (tC02e)

193,072 tonnes​
203,626 tonnes​
213,927 tonnes​

Target: 50% reduction in net greenhouse gas emissions by 2025, 85% by 2035, and net zero by 2050, compared to baseline 2020 emissions.

Although the expansion of our operational footprint across North America and growing community demands have resulted in overall yearly increases, we are still on track to meet our 2025 target.

Climate mitigation: Our pathway to net zero​​​

P​​rotect river water quality

​4​​4,321 kilograms/day

Annual discharges of suspended solids into the North Saskatchewan River from land drainage, wastewater treatment operations and combined sewer overflows (kg/day)*

45,205 kg/day​
62,245 kg/day
​65,245 kg/day
31,312 kg/day​​
44,321 kg/day​​

Performance measure: annual discharges of total suspended solids into the North Saskatchewan River from land drainage, water and wastewater treatment operations, and combined sewer overflows.

*Data from 2018 to 2021 was recalculated using new methodology in 2022. Learn more about our methodology and sources of solids loading.

Our work to protect river water quality​​​​

Implementation of Edmonton flood resilience upgrades

Protect utility assets and critical infrastructure from river flooding to at least a 1:200-year flood event (percentage implemented)​

Implementation of Edmonton flood resilience upgrades


Protect utility assets and critical infrastructure from river flooding to at least a 1:200-year flood event (percentage implemented)

2020​ ​4%

Target: complete asset protection and relocation, and backflow prevention, by 2024; and complete flood barriers by December 2027.

*The calculation for progress was improved in 2022 and now includes all flood mitigation components being implemented.

Limi​​t water loss


​Limit the percentage of treated drinking water lost due to transmission and distribution line leaks and failures, and inaccurate meters (U.S. and Canada combined).


Performance data only, with reporting lagging by one year.

W​​astewater reuse (USA)


Percentage of treated effluent reused or used to recharge aquifiers (not including San Tan operations).

2020​ 94.4%​

Target: 90% beneficial reuse and/or recharge of treated effluent by existing U.S. operations and a commitment to set targets for each ne​​w, expanded or acquired U.S. wastewater operation in arid regions.

Environment and climate change at EPCOR

At EPCOR, we're minimizing our own environmental footprint, reducing our greenhouse gas emissions, and enforcing an enterprise-wide Integrated Health, Safety & Environment Management System. These actions, and many others are outlined in our environment and climate change strategy, our climate mitigation plan, and our environment management foundations information.

Our commitment to the environment


​Our commitment in action

From protecting our water to investing in green energy, our environment and climate change strategy is supported by real actions that are making a measurable difference in protecting our environment. We’re building stronger infrastructure and communities, and we’re doing it in a way that positively impacts the environment and address climate change.
