Scope 1 and 2 emissions: 161 tCO2e (+81%)
Revenue: £81m*
Emissions per £1m revenue: 2.0 tCO2e

The Swedish and Finnish arms of this Nordic reseller and MSP powerhouse have both committed to the Science Based Targets initiative, with the former having its targets approved in June 2023.
Advania’s UK business – which is based on its 2021 acquisition of Content+Cloud – saw its Scope 1 and 2 emissions rise 81% to 161 tCO2e in calendar 2022, according to its latest SECR disclosure.
The UK business is “committed to achieving net zero by 2030”, Advania Group’s 2022 Sustainability Report states. In an effort to cut air and inter-office travel, the UK arm has recently built more governance into the justification and approval process, and has also seen “significant update across the business” of an electric car salary sacrifice scheme.

20. Natilik
Scope 1 and 2 emissions: 26 tCO2e
Revenue: £96m
Emissions per £1m revenue: 0.3 tCO2e

Becoming a B Corp in January 2023 has made London-based Natilik “look at ourselves and mark our homework”, its Chief People Officer Kelly White told IT Channel Oxygen.
Natilik pegged its Scope 2 emissions at 26 tCO2e in its fiscal year to 31 March 2023, according to its latest SECR disclosure. Its reported Scope 1 emissions were zero (as it does not own vehicles and leases accommodation from managed service office providers).
Some 54% of its reported Scope 3 emissions – which totalled 522 tCO2e – were attributed to employee commuting.
Natilik has recently engaged one of its clients, the Energy Savings Trust, to carry out an environmental audit of the business this summer, meanwhile. “We want to go a step further and set some net zero targets,” White added of the partnership.
19. ARO
Scope 1 and 2 emissions: 876 tCO2e (+77%)
Revenue: £99m
Emissions per £1m revenue: 8.9 tCO2e
This rapidly expanding business comms and IT provider saw its reported Scope 1 and 2 emissions rise by 77% to 876 tCO2e in calendar 2022, according to its most recent SECR disclosure.
Arrow’s car fleet of 52 vehicles comprises 46 EV or hybrids, with the remaining eight set to be replaced by hybrid/electric at end of lease, the report noted.
Solar panels are live at one of its sites, with a viability project for its Liverpool datacentre also being undertaken, the Godalming-based outfit added.
18. ANS
Scope 1 and 2 emissions: 6,191 tCO2e (+1%)
Revenue: £119m
Emissions per £1m revenue: 52 tCO2e
Going LED-only across its datacentre estate in 2022 saved 50% in energy use, ANS said in its 2023 ESG Impact report.
The report also flagged up the Manchester-based cloud and digital transformation outfit’s introduction of an electric car scheme with free charging.
Although ANS’ reported Scope 2 emissions fell from 5,848 to 5,004 tCO2e in calendar 2022, an increase in refrigerants stemming from a large-scale datacentre project saw its Scope 1 emissions hike from 298 to 1,186 tCO2e.
ANS pegged its Scope 3 emissions at 1,843 tCO2e (its reporting here spanned seven categories).
