Energy & Carbon Audits That Turn Data Into Decisions
Engineering-led ISO 50002 audits for large pharmaceutical, food and beverage and chemical sites, where energy is a material cost and carbon targets are already in place.
- Engineering-led, not a desktop benchmarking exercise
- Carried out in line with ISO 50002
- Targets the systems driving around 85 to 90% of your energy use
- Ends in an investment-ready roadmap, not a list of ideas
- Part of SHV Energy
- ISO 50001
What This Service Is
An Energy & Carbon Audit is the starting point for most of the work EM3 does with industrial clients. It is not a high-level review or a compliance exercise. It is a structured, engineering-led assessment of how a site actually consumes energy, what is driving its carbon emissions, and where realistic opportunities exist to reduce both.
The audit is carried out in line with ISO 50002, but the intent is practical rather than procedural. The goal is to understand the site in enough detail to move from observation to action, identifying specific opportunities that can be turned into real projects with defined savings and investment cases.
Our engineers go beyond reviewing utility bills or benchmarking performance. They analyse how energy flows through the site, how systems interact, and how the facility is actually operated day to day.

The Challenge It Solves
By the time a client engages EM3, the problem is rarely a lack of data. Most sites already have utility bills, metering information and internal reporting. What they do not have is a clear view of what is actually happening across the site, so opportunities stay unclear, unquantified or disconnected and investment decisions stall.
In practice, most teams cannot answer the questions that decide where to start:
- Which systems are genuinely driving energy cost
- How the different utilities interact
- Where the biggest losses are occurring
- What to tackle first, and what it is worth
How EM3 Delivers It
Data request
You share around 12 months of electricity, fuel and other consumption data. We use it to build an initial picture of the site and pinpoint where most energy is used, focusing on the systems responsible for roughly 85 to 90% of total consumption.
Scope alignment
We meet your site team to agree the scope and confirm which areas of the facility we will examine in detail.
On-site assessment
Our engineers walk the facility, review the major utilities and talk to operational staff. Steam, HVAC, compressed air, chilled water and process loads are assessed in context, for how they behave together rather than how each performs on its own.
Opportunity development
We turn what we observe into a structured list of energy and carbon reduction opportunities, tied to the actual systems and conditions on your site rather than generic suggestions.
Interim review
We hold an interim discussion with your team to surface constraints, operational limits, regulatory requirements and process dependencies, so the final recommendations are realistic and implementable.
Report and roadmap
We deliver the audit report and a phased roadmap that sequences the work from your current state to lower cost and lower carbon.
What You Receive
Energy, carbon and cost baseline
A full breakdown of how energy use, carbon emissions and costs are distributed across your systems and processes, establishing a clear baseline.
System-level analysis
Energy consumption by system, electrical and fuel usage profiles, and thermal demand and heat usage, all analysed at system level.
Significant Energy Users identified
The systems that account for the majority of your consumption (your SEUs), pinpointed so effort and investment go where they count.
Sankey energy-flow diagrams
Visual representations of how energy moves through the facility, making losses and inefficiencies visible in a way raw data cannot.
Quantified opportunity list
Each opportunity grouped by system or theme, with estimated energy savings, carbon reduction, IRR, NPV and an indication of implementation complexity.
Phased decarbonisation roadmap
A sequenced plan with estimated investment, showing how the site moves from its current state to lower cost and lower carbon over time.
Proven Outcome
In one completed audit at a single large industrial facility, EM3 identified a total carbon reduction potential of 4,693 tonnes of CO2. This was broken down into defined projects spanning HVAC optimisation, controls improvements, renewable energy integration and process-level decarbonisation.
Alongside it we produced a full financial pathway: around $28.6 million of required capital investment and around $14.1 million of available grant and rebate support. The client left with a structured, investment-ready plan, not just a list of ideas.
Why EM3
Independent of vendors
We do not sell equipment or technology, so recommendations are driven by total cost of ownership and long-term performance, not sales incentives.
Engineering-led, at system level
We assess how systems actually perform together, not high-level benchmarks or theoretical models, which is where the largest gains are found.
Built to lead into delivery
The output is not just descriptive. It is structured to become a pipeline of projects that can be funded, designed and delivered.
Part of SHV Energy
EM3 is part of SHV Energy, working across multiple countries with deep sector experience in energy-intensive manufacturing.
How We Engage
Frequently Asked Questions
How long does an energy and carbon audit take?
Around ten weeks for a full audit with a decarbonisation roadmap, covering data collection, analysis, the on-site assessment, opportunity development and final reporting. The exact timeline depends on site size and complexity.
What standard is the audit carried out to?
It is carried out in line with ISO 50002. The intent is practical rather than procedural: we use the standard to structure the work, but the goal is action, not paperwork.
What happens during the on-site assessment?
Our engineers walk the facility, review the major utilities and speak with operational staff. Steam, HVAC, compressed air, chilled water and process loads are assessed in context, for how they behave together rather than in isolation.
What does the client receive at the end?
A working report: an energy, carbon and cost baseline, system-level analysis, your Significant Energy Users, Sankey energy-flow diagrams, a quantified opportunity list and a phased roadmap you can fund and act on.
How are the opportunities quantified?
Each opportunity is grouped by system or theme and comes with estimated energy savings, carbon reduction, financial metrics such as IRR and NPV, and an indication of implementation complexity.
What happens after the audit?
The roadmap is built to lead straight into delivery. It sequences the projects and the investment so they can be funded, designed and delivered, with measurement and verification to confirm the savings.
