What’s changing
The KEY ESG carbon calculators (our tool for building up scope 1, 2 and 3 emissions from activity data, like fuel use or electricity bills) can now be switched on or off per organisation. This means we can offer the calculators as an add-on rather than including them for every account by default.
If your organisation was already set up and explicitly includes the carbon calculators, you keep the calculators exactly as they are. There’s nothing for you to do.
If you’re a new organisation joining after and do not have the calculators included in your license, you’ll start by reporting your scope 1, 2 and 3 emissions as direct totals, and you’ll see exactly what the calculators would add, with a one-click way to request them.
Reporting your totals directly
If you don’t have the calculators, each scope now opens straight on direct entry, so there’s no setup to work through first. On each scope page, you’ll see:
A banner showing what the KEY ESG calculators would calculate for that scope, with a Request the calculators button
A Data entry method: Direct entry button, which opens a method picker showing the calculators as a locked option, tagged Add-on
If you used the calculators for that scope last year, the page will tell you so, for example: “In 2025, scope 1 was set up for the KEY ESG calculators. Your 2025 data and reports are unchanged.” Nothing from a previous year is affected.
If the calculators are switched off for your organisation
If you’ve been using the calculators and they’re switched off, any data you’ve already entered through them stays exactly as it was, and still counts towards your totals and reports. It simply becomes read-only: you’ll see a Read-only label and a lock icon on those entries, and editing, uploading evidence, and similar actions are disabled.
A banner on the page explains the benefits of keeping the calculators (emission factors applied and kept up to date, emissions broken down by source and entity, and factors recorded in your audit report), and you can switch to direct entry instead if you’d prefer. Nothing is ever deleted: if the calculators are switched back on later, your data and access return exactly as they were.
Requesting the calculators
Wherever you see Request the calculators, clicking it sends a request straight to your account manager, and you’ll see a confirmation message letting you know they’ll be in touch. (Requests for CSRD access now go through the same route, to support@keyesg.com.)
A few other things to know
For scope 3, Category 3: if scopes 1 and 2 are entered as totals rather than through the calculators, Category 3 will hide the rows that would otherwise be calculated automatically, and you’ll need to complete that category by hand.
If you switch from the calculators to direct entry, your calculator entries are removed after a confirmation step. This is a one-way action for now, there isn’t yet a way to restore them if you switch back.
If you have any questions about which option is right for your organisation, reach out to your account manager or support@keyesg.com.
