Greenly alternative: how TrackZero compares for carbon accounting
If you’re looking for a Greenly alternative, you may be approaching renewal, reviewing costs, or asking whether your business still needs the same level of consultancy-led support — or if software can do more of the work.

TrackZero is significantly more affordable than Greenly, but it is not a stripped-back imitation. Both carbon accounting platforms help organisations measure Scope 1, 2 and 3 emissions, plan reductions and engage their supply chains. The difference lies in how the service is delivered.
Greenly combines its software with a relatively high level of ongoing expert support. TrackZero gives internal teams the tools to manage more of the process themselves: gathering data, reviewing calculations, producing reports and maintaining the reporting process year after year. Users retain the option to involve a consultant, but can choose to do that where specialist expertise is required.

What is the main difference between Greenly and TrackZero?
Greenly and TrackZero support different ways of measuring, reporting on, and reducing your carbon footprint.
TrackZero
TrackZero is more deliberately software-led. It provides the structure, calculations, reporting tools and audit trail an internal team needs to manage carbon accounting itself. Support is still available through TrackZero partners or your own carbon consultant, but you do not have to buy a heavily supported service to access the software.
Crucially, the consultant is separate from the platform. You can work with a TrackZero partner, use your existing adviser, manage the process entirely in-house or change consultants later without losing the platform or the data held within it. Your reporting history, calculations and supporting evidence remain with your organisation, so changing adviser does not mean rebuilding the process from scratch.
Greenly
Greenly positions itself as an all-in-one sustainability suite combining carbon accounting software, reporting and access to climate experts. Its platform covers broader international use cases, including GHG disclosure, product carbon footprints and ESG compliance. Greenly says online support is included in all packages and customers can receive help from a dedicated climate expert.
This model suits businesses that want a higher level of guidance throughout the carbon reporting process, or prefer an external expert to play a significant role.
For some businesses, outsourcing more of the work will be the right choice. For others, especially those that have already completed one or more carbon footprints, paying for the same level of external involvement every year may no longer be necessary.
“Once assurance enters the picture, a spreadsheet stops being enough. You need to be able to show your working, and stand behind it. TrackZero gives you the infrastructure to do the work properly, without getting in your way.”

Why organisations bring carbon accounting in-house
The first footprint is the hardest
The first carbon footprint is often the most difficult. Many businesses need help establishing their reporting boundary, deciding which Scope 3 categories are relevant, identifying the right data sources and selecting appropriate calculation methods. Internal responsibilities may not yet be clear, and different departments may not understand what information they need to supply. Once that work has been done, the picture changes.
The process doesn’t become effortless, but it becomes more familiar and repeatable. Instead of starting again, you improve the quality of the same underlying process each year.
What bringing it in-house unlocks
Bringing carbon accounting in-house can help a business:
- Retain knowledge of its boundaries, methods and assumptions
- Give internal teams greater visibility over the final footprint
- Create a repeatable annual reporting process
- Retain the freedom to change consultants without changing platforms or losing reporting continuity
- Direct consultancy spend towards complex or strategic work
You still collect the underlying data
There is another practical consideration: the business usually has to collect much of the underlying data regardless of which platform or consultant it chooses.
An external expert can tell you what information is needed, help interpret it and review the results. They cannot independently obtain every energy bill, mileage record, finance export, supplier response or waste report held across your organisation. The question isn’t whether consultant-led software has value; it’s whether every part of the process requires support.
How TrackZero supports in-house carbon accounting
TrackZero is designed to give internal teams enough structure to complete robust carbon accounting without leaving them to build the entire process from a blank spreadsheet.
Guided data collection
Guided Scope 1, 2 and 3 data collection so teams know what to gather and where it belongs.
Transparent calculations
Transparent calculations and supporting evidence you can review, explain and stand behind.
UK reporting & plans
UK carbon reporting and reduction planning, including SECR and Carbon Reduction Plans.
Supplier engagement
Supplier engagement and Scope 3 data collection with requests, reminders and response tracking.
Expert support when needed
Access to expert support — or your own external consultant — without locking it into the platform.
Why does TrackZero cost less than Greenly?
A different support model
TrackZero is not less expensive because it offers less carbon accounting software. It is less expensive because organisations choose how much expert support they need, rather than paying for a consultancy-led service model by default.
Greenly combines its platform with a relatively high level of ongoing expert involvement. That can be valuable for organisations that want an external team to remain closely involved throughout measurement, reporting and reduction planning, but it also contributes to the overall cost.
Choose how much support you buy
TrackZero gives organisations more choice. The same core platform supports carbon measurement, reporting, reduction planning and supply-chain engagement, while the level of support varies by package. Teams that are comfortable managing more of the process internally can choose a self-serve plan. Those that want closer guidance can choose an expert-supported package, commission a bespoke solution or work with their own external consultant on the platform. TrackZero’s pricing reflects that flexibility.
Comparing like for like
Most organisations considering a move from Greenly are unlikely to use TrackZero’s £295 Essentials plan. A more realistic comparison will usually be Comply, Accelerate or a bespoke package.
Even at those levels, TrackZero can remain significantly more affordable because customers are not automatically paying for substantial ongoing consultancy time. They pay for the software and the level of expert involvement that suits their organisation.
The price difference is therefore not about offering less capable software. It reflects a different model: one that separates the platform from the support wrapped around it and gives customers greater control over what they buy.
Why TrackZero is technology-first
TrackZero is a technology-first business. Our model depends on making the platform as useful, intuitive and capable as possible, because the software is the product — not a gateway to selling additional consultancy. That means our incentive is to improve the technology, remove unnecessary friction and help users complete more of the carbon accounting process efficiently within the platform.
Because additional consultancy is not the basis of our business model, our focus is on helping users complete as much as possible efficiently within the platform. Our success depends on the technology delivering value in its own right, with expert input available where it is genuinely needed.
Who each platform is best suited to

Book a CallConclusion: choosing the right Greenly alternative
The right carbon accounting platform is not necessarily the one with the longest feature list or the highest level of support. It is the one that reflects how your organisation wants to work.
Greenly may suit a business looking for a broad carbon and ESG platform with ongoing expert guidance built into the proposition.
TrackZero is designed for organisations that want to own more of the process: collecting and managing their data internally, understanding their calculations, producing UK-focused reports and involving experts when their expertise adds genuine value.
If carbon accounting is becoming a repeatable internal process rather than a consultancy project, TrackZero gives your team the tools to manage it with confidence while keeping expert support available when it is genuinely needed.
