Carbon reduction commitment software: the CRC ended in 2018
The CRC Energy Efficiency Scheme was revoked from 1 October 2018 and closed after the 2018–19 compliance year, so there is no carbon reduction commitment for software to report to.
Its reporting role passed to SECR, the energy and carbon disclosure in the directors’ report, and the software to look for now is software that produces every SECR line.
What happened to the CRC
Revoked, with savings, from 1 October 2018
The CRC Energy Efficiency Scheme ran under the CRC Energy Efficiency Scheme Order 2013, which legislation.gov.uk now titles “(revoked)”.
The Revocation and Savings Order 2018 revoked it from 1 October 2018, while saving the provisions needed to finish the last compliance year.
The government’s post-implementation review of SECR describes the 2018 package that announced the CRC’s closure after the 2018–19 compliance year.
Final allowance surrender was due by the end of October 2019, the registry was kept to 31 March 2022, and records were to be kept to the end of March 2025.
The government’s own CRC pages remain online as a record, and the 2019 SECR guidance still mentions the CRC as though it were running; it is not.

What replaced it
SECR took on the reporting; the scheme itself was not replaced
For reporting, the successor is Streamlined Energy and Carbon Reporting, inserted into company law by SI 2018/1155 for financial periods beginning on or after 1 April 2019.
SECR puts energy use in kWh, the related emissions, an intensity ratio, the methodology, energy-efficiency action and last year’s figures into the directors’ report, under Schedule 7 to the accounts regulations.
Quoted companies report; large unquoted companies and LLPs report when they exceed at least two of £36m turnover, £18m balance sheet and 250 employees, judged over two consecutive years after the first.
The test is framed as “not more than” on the exempt side, so a company sitting exactly on a limit is not over it.
The full scope test is on SECR reporting requirements, and the scheme itself on SECR.
ESOS, the four-yearly energy assessment for large undertakings, is a separate duty with its own test, set out by the Environment Agency.

ESOS is a separate test for large undertakings.The software to look for now
SECR software: every Schedule 7 line
A former CRC tool built around allowances and league tables has nothing to do under SECR, which asks for a disclosure, not a trading position.
What a SECR tool must produce is set out line by line on SECR reporting software, which is the page to read next.
The figures underneath — activity data, the DESNZ factor set for the activity year, and the working behind each number — are the job of carbon accounting software.
The independent evaluation of SECR informed the government’s 2026 review, which kept the regime.
Old CRC data
The post-implementation review records that SECR’s original cost estimate was built from CRC data.
A company’s own CRC figures can show a long-run energy trend, but SECR’s comparatives are the previous SECR year.
| What SECR asks for | What a tool must hold |
|---|---|
| Energy in kWh | Meter, bill and fuel data by period, for the UK (and globally for quoted companies) |
| Emissions | The DESNZ factor set for the activity year, stored with each figure |
| An intensity ratio | Your chosen denominator, held beside the emissions |
| Methodology | A written method a director can sign off |
| Energy-efficiency action | A narrative field, not just a chart |
| Last year’s figures | The previous year reproduced as published |

Frequently asked
The CRC and its software, answered
Is the Carbon Reduction Commitment still running?
No. The CRC Energy Efficiency Scheme was revoked from 1 October 2018 by SI 2018/841 and closed after the 2018–19 compliance year.
Final allowance surrender was by the end of October 2019, the registry was kept to 31 March 2022, and records were to be kept to the end of March 2025.
What replaced the CRC?
For reporting, Streamlined Energy and Carbon Reporting (SECR), inserted by SI 2018/1155 for financial periods beginning on or after 1 April 2019, which puts energy and carbon figures in the directors’ report.
The government’s post-implementation review of SECR describes the same 2018 package announcing the CRC’s closure.
Do I need carbon reduction commitment software?
No, because there is no CRC to report to.
If your company is quoted, or a large unquoted company or LLP, you report under SECR instead, and the software question becomes whether a tool produces every SECR line.
Who has to report under SECR?
Quoted companies, and large unquoted companies and LLPs.
An unquoted company is large when it exceeds at least two of £36m turnover, £18m balance sheet and 250 employees — the test is framed as “not more than” on the exempt side — judged over two consecutive years after the first.
Can old CRC data still be useful?
Yes, as history.
The government’s post-implementation review records that SECR’s original cost estimate was built from CRC data.
For a company’s own reporting, old CRC figures can show long-run energy trends, but SECR comparatives are the previous SECR year, converted with the factors for that activity year.
Which software reports SECR?
Most carbon accounting platforms say they cover energy and emissions; 16 of the 60 carbon accounting vendors in this site’s registry make a SECR claim on their own pages. This site has tested none.
Test any tool against every SECR line, including the kWh figure, the intensity ratio, the methodology and last year’s figures.
