The 5 features emissions tracking software should have

Emissions tracking software helps a business measure, report and reduce its carbon footprint on one platform. When you compare carbon emission software, five features matter most: automatic data import, a clear view of emission hotspots, coverage of the UK rules you report under, supplier data collection for Scope 3 and built-in reduction planning. Each section below explains what to look for and gives you a test to run in a vendor demo, using your own data. Regulation is moving too: the UK published its sustainability reporting standards (UK SRS) in February 2026, and the FCA finalised its listing rules for them in September.

The method behind it is greenhouse gas accounting: every figure is an activity multiplied by an emission factor, sorted into three scopes. Scope 1 covers direct emissions from owned or controlled sources, Scope 2 covers emissions from purchased energy, and Scope 3 covers all other indirect emissions in the value chain. Some vendors sell the same job as carbon tracking software or carbon footprint tracking software, and it sits at the heart of carbon accounting.

In the UK, the stakes have risen. The Department for Business and Trade published final UK SRS S1 and S2 on 25 February 2026, and the FCA’s final rules apply them to listed issuers from 2027. Both raise the bar on data quality and audit trail.

It should, and it should flag errors as it goes. The best tools take your accounting files, energy data and supplier records directly, instead of asking you to rekey spreadsheets.

Collecting and cleaning data is usually the hardest first step, so import speed and accuracy shape everything that follows. The software should accept four main sources: accounting ledgers, energy bills and meter readings, travel records and supplier data. Look for connections to the systems you already use, such as your accounting package or ERP, so the data does not need re-entering each year.

The type of data also drives accuracy. The GHG Protocol’s Scope 3 calculation guidance describes four methods for purchased goods and services: supplier-specific, hybrid, average-data and spend-based. Supplier-specific and hybrid methods need supplier data, while average-data and spend-based methods rely on industry averages. Spend-based is the fallback when other methods are not feasible.

The Department for Energy Security and Net Zero (DESNZ) publishes UK government conversion factors each year. They convert activity data, such as litres of fuel or kWh of electricity, into Scope 1, 2 and 3 emissions for UK operations. The 2026 set was published on 11 June 2026, so check that the tool applies current factors and records which version it used.

To test this feature, run a live import of your own files in the demo. Check how the tool flags errors, and whether each figure traces back to its source line.

It should, and quickly. A good tool ranks your emissions by activity, supplier and site, so you can see where reductions will count. This is called hotspot analysis.

Why does hotspot analysis matter?

Hotspots differ by industry, scale and business model. A manufacturer may find that its production processes are the largest source, while a service firm may find that commuting and business travel dominate. Knowing which is which lets you direct effort and budget where it cuts the most emissions, which makes carbon management cheaper as well as more efficient.

Check that the tool can slice results by scope and by category, and drill down to the underlying records rather than only showing a total.

To test this, ask the vendor to rank your emissions by activity, supplier and site in the demo, using your own data.

It should produce the output each framework asks for, and show how every figure was calculated. Four frameworks matter most to a UK company, and the first two changed during 2026.

Law firm CMS reports that the government will review how UK SRS and SECR interact, to reduce duplication.

For finance teams, the audit trail matters most. To test this feature, ask the vendor to produce each framework’s output from your data and show how one figure was calculated, including who can see the source record behind it.

It should, because the value chain is where the largest share of emissions often sits. CDP found that in 2023, companies disclosing to it reported supply chain emissions 26 times higher than their Scope 1 and 2 emissions on average. Only 15% of them had set a supply chain emissions target.

Supplier data is what lets you replace spend-based estimates with figures specific to each source of Scope 3 emissions. A supplier workflow should cover four steps: invitation, questionnaire, validation and an audit trail showing where each figure came from. Validation matters because supplier figures vary in scope and quality, so the tool should flag gaps and outliers before they reach your Scope 3 total.

To test this, invite one of your real suppliers during the evaluation and check where its data lands in your Scope 3 total.

It should, because a footprint only pays off when it leads to action. Look for four functions in the same tool as your footprint: target setting, reduction scenarios, action assignment and progress tracking.

A reduction plan has to fit your emission sources, processes and objectives, so the tool should let you test options and compare their effect before you commit budget. Suppliers, customers and employees all play a part, so the plan should also record who owns each action.

To test this, ask the vendor to build a sample plan with targets and progress linked to your footprint data.

The five features above work as a checklist for any platform, including Greenly’s. Four extra questions are worth asking every vendor:

• How much manual work does data entry actually require? Some platforms automate collection from your existing systems; others leave you uploading spreadsheets by hand.
• Does it cover Scope 3 as well as Scope 1 and 2? Supply chain emissions are often far larger than direct ones, so a tool that stops at direct emissions leaves your biggest opportunity untouched.
• Which frameworks does it map to? GHG Protocol coverage is table stakes; check whether it also handles the rules you report under, such as UK SRS, SECR or CSRD.
• What happens after the measurement? A platform that stops at a number leaves you to build the reduction plan yourself.

Use this table to turn each feature into evidence to request in a demo.

What is the best software for tracking carbon emissions?

The best software for tracking carbon emissions depends on your company’s size, your reporting frameworks and your Scope 3 needs. A company reporting under SECR alone needs different depth from a listed group preparing UK SRS disclosures. Apply the table above to each shortlisted vendor and compare the evidence side by side. To compare named products, the UK top 10 carbon management software covers ten options.

Greenly is the carbon accounting and climate management platform that helps companies measure, reduce and report their emissions with AI. It answers the problems above in four ways:

• Manual data entry. Greenly imports accounting, Excel and CSV files directly, adds physical flow data and integrates with more than 100 systems through APIs, including ERP and accounting tools.
• Choosing the right factor. Each entry is matched against more than 300,000 traceable emission factors, and the 2026 UK government conversion factors are already built in.
• Supplier data. Greenly sends suppliers a questionnaire, scores each one on more than 40 criteria with a grade from A to E, and logs every data entry for auditor review.
• Plans that follow the footprint. Targets, reduction plans and progress tracking sit in the same platform as the data.

More than 3,500 companies use Greenly to measure, report and reduce their emissions. Request a free demo with one of our experts to see Greenly’s carbon footprint platform running on your own data.
