Metrus Impact Report
Investing in Energy as a Service
We are leading the way to a sustainable, low-carbon future by bringing energy efficiency and clean energy projects to life.
Metrus has operational Sustainable Energy Services Agreement (SESA) projects in 34 states, encompassing more than 940 sites.1 Our portfolio consists of over 30 different types of energy efficiency measures and technologies.
Energy Efficiency Measurements (EEMs)
79% of Metrus projects involve multiple measures, which is consistent with our efforts to bundle upgrades with varying economic and technology profiles to achieve scale. Although 97% of Metrus SESAs include LED lighting upgrades, 48% of all CO2 savings this year originated from non-LED lighting measures. The non-LED lighting measures include deep retrofits to compressed air systems, boilers, chillers, cooling towers, and building automation systems. This performance reflects Metrus’s expertise in executing complex, multi-site, multi-measure, SESAs.

Annual Performance
Over the last decade, our realized savings have exceeded the expected savings (as projected in an initial energy audit) each year. On average, our portfolio performs at 101.5% of its expected savings.2

CO2 Savings per $1,000 of Investment
Metrus measures the efficiency of its investment portfolio in reducing CO2 (metric tons) by using CarbonCount™ as a scoring tool.3 Higher ratios mean greater carbon reduction per $1,000 of investment.4 The data below represents the average scoring for Metrus projects located within 21 different regional eGrid zones.5 Our investments in the SPNO and SRMW zones have the highest CO2 efficiency ratings due in large part to the higher carbon content in the midwestern power grid.

Environmental performance is interwoven into each of our projects. We prepare annual reports that detail project-level CO2 savings broken out by scope 1 and scope 2 emissions to facilitate customer reporting under SBTi.6 This is also our second year of reporting on Metrus’ annual reduction of sulfur oxides (SOx) and nitrogen oxides (NOx), atmospheric pollutants caused by burning fossil fuels.

2024: SOx and NOx
In addition to reducing greenhouse gases, our efforts to accelerate the transition to a sustainable, low-carbon future directly reduce atmospheric pollutants such as sulfur oxides (SOx) and nitrous oxides (NOx). In 2024, Metrus reduced SOx emissions by 36 metric tons and NOx emissions by 53 metric tons. These reductions are helping to achieve the levels set forth in the EPA’s National Ambient Air Quality Standards (NAAQS).

2024: Total Annual Energy Savings
Our projects include a wide range of energy efficiency improvements that generate both electric and thermal energy savings.10
In 2024, our portfolio saved a total of 763,579 MMBtu of energy. That’s equivalent to 131,652 barrels of oil.11

2024: Total Water Savings
According to the EPA, office buildings, hospitals, hotels, and schools, among other commercial and institutional facilities, use 17% of the public water supply, making the sector the 2nd largest consumer in the country.12
Metrus has projects with water efficiency measures across private sector business, higher education, and healthcare customers. According to the EPA, each American uses an average of 82 gallons of water per day at home. So, the 77,345,253-gallon reduction in water consumption is equivalent to the water used by 2,584 Americans for an entire year.

A holistic look at our overall carbon impact, including Metrus’ own emissions.
While we maintain a low energy profile within our own built environment, we take responsibility for the impact of scope 3 emissions for assets that we own and install on behalf of our customers. Our goal with this report is to provide complete transparency into the energy savings and environmental impact of our business as well as our project investments.
Our Scope 1 Emissions
Metrus generates no direct emissions from fuel combustion.
0
Our Scope 2 Emissions
For its office space, Metrus purchases utilities that produce emissions.
18
Our Scope 3 Emissions / Travel
For employee travel and commuting, Metrus generates a nominal amount of emissions.
176
Our Scope 3 Emissions / Assets
Metrus’ project assets consume energy and produce CO2, albeit more minimally than the equipment they replaced.

Metrus is committed to accelerating and scaling climate action by financing, owning, and operating sustainable energy projects.
Sixteen years ago, we introduced a groundbreaking finance solution that enables companies to decarbonize and reduce their environmental impact with no upfront cost. We remain steadfast in our mission to drive climate action by championing energy efficiency projects and accelerating the transition to a sustainable, low-carbon energy future. We’re living at a pivotal time when investment, innovation, and decisive action can make a real difference in the shape of tomorrow and we’re fully committed to driving progress and being accountable.
Our Partnerships

$300 million
The Department of Energy’s Better Buildings Challenge is a partnership of businesses, manufacturers, cities, states, universities, and school districts committing to improve the energy efficiency of their buildings by at least 20% over 10 years. Metrus was one of the first financial allies to join this program. After exceeding our first two commitment goals, we’ve recently reupped our target to $300 million.

$200 million
The America Is All In initiative (formerly We Are Still In) is a diverse coalition of U.S. leaders who support halving U.S. emissions by 2030 and reaching net zero emissions by 2050. As part of this ongoing initiative, Metrus increased its financing commitment from $100 million of sustainable energy projects to $200 million and is now 43% of the way towards its new target.

In 2021, Metrus became a signatory to the internationally-recognized Principles for Responsible Investment (PRI), publicly demonstrating our commitment to responsible investing, at a global level. We join an international cadre of investors and asset owners who believe that an economically efficient, sustainable global financial system is a necessity for long-term value creation

In 2023, Metrus joined Mission Efficiency in their pursuit to accelerate the transition towards energy efficient economies worldwide. Mission Efficiency is a collective of actions, commitments, and goals from a coalition of governments, organizations, and initiatives coming together to drive progress on energy efficiency, and Metrus is providing strategic support on key issues in the US.

The Cool Coalition is a partnership of proactive governments, businesses, and civil society organizations that aims to accelerate progress toward efficient and climate-friendly cooling. Metrus joined the coalition in 2023 in order to promote the adoption of environmentally friendly cooling technologies and to facilitate equipment upgrades through its Energy as a Service financing solution. As part of the first-ever Global Cooling Pledge announced at COP28, Metrus has committed $100 million in sustainable cooling projects.
