Understanding Scope 3 & Sustainable IT Governance: Where Should SMEs Start?
14 September 2026
For SMEs trying to understand the carbon emissions associated with technology, building a complete picture can quickly become complicated. This includes both the energy used to operate the IT estate, which can contribute to Scope 2 emissions, and the wider Scope 3 emissions associated with the asset lifecycle.
IT equipment has an environmental and financial impact long before it arrives in the organisation and long after it leaves. Manufacturing, transportation, procurement, use, replacement and end-of-life treatment can all contribute to the overall footprint and cost of the IT estate. Better lifecycle decisions can help organisations avoid unnecessary replacement costs, improve asset utilisation and reduce ongoing energy consumption. Sustainability credentials are also increasingly important within supply chains, particularly when organisations are bidding for larger contracts or public-sector opportunities, where environmental requirements can form part of procurement and ongoing supplier assurance.
The challenge is therefore not simply calculating a carbon number.
It is understanding enough about the IT estate to make better decisions.
Understanding Scope 2 and 3 emissions.
Carbon emissions associated with an IT estate sit across different emissions scopes.
Scope 2 relates to indirect emissions associated with purchased energy. For technology, this can include the electricity used to operate IT equipment and infrastructure.
Scope 3 covers other indirect emissions across an organisation’s value chain. For IT, this is particularly important because much of the environmental impact associated with technology can occur before equipment enters the organisation and after it leaves.
A laptop, server or other device has already generated environmental impact through raw-material extraction, manufacturing and transportation before it is switched on for the first time.
Its impact continues through use and ultimately through reuse, recycling or disposal.
Looking at both operational energy and the wider asset lifecycle therefore provides a more complete picture of the carbon emissions associated with IT.
Why IT asset data matters
Understanding the IT estate is an important starting point.
What assets does the organisation have?
What models are they?
How old are they?
How long are they being retained?
What happens when they reach the end of their first useful life?
The quality of environmental information associated with those assets matters too.
Manufacturer and model-level information can provide greater specificity than broad averages. Where detailed data is unavailable, estimates and averages may still provide a useful starting point.
The objective should not be to wait indefinitely for perfect data.
It should be to understand what information is available, recognise its limitations and improve the baseline over time.
Measurement should influence decisions
Once an organisation understands more about its IT carbon impact, the next question is what it does differently.
Could some assets remain in service for longer?
Could equipment be redeployed rather than replaced?
Should environmental information form part of procurement?
Are suppliers providing useful sustainability information?
What happens to equipment at end of life?
These are not simply carbon-accounting questions.
They are procurement, IT Asset Management, risk and governance decisions.
That is why Sustainable IT needs to extend beyond reporting.
From measurement to action
A practical Sustainable IT approach starts with building sufficient visibility of the IT estate and its environmental impact to understand the current position.
That information can then support procurement, asset management, governance and operational decision-making.
The organisation can monitor the effect of those decisions, improve the quality of its data and identify further opportunities for action over time.
COzPro supports this process by helping organisations understand and manage the carbon impact associated with their IT estate, while KA2’s consultancy expertise helps connect that information with wider governance and operational decisions.
