Carbon Reduction Plan
Carbon Reduction Plan
Supplier Name: Solirius Reply Ltd
Publication Date: 25th September 2026
Commitment to achieving Net Zero
Solirius is committed to achieving Net Zero emissions by 2030.
Baseline Emissions Footprint
Baseline emissions are a record of the greenhouse gases that have been produced in the past and were produced prior to the introduction of any strategies to reduce emissions. Baseline emissions are the reference point against which emissions reduction can be measured.
Baseline Year: 2019
Additional Details relating to the Baseline Emissions calculations.
Scope 1 emissions are not applicable to Solirius Reply - as a technology services company we do not produce emissions directly through owned or controlled sources. In previous years we have calculated Scope 2 emissions which are related to the rented company office space, however our data for Scope 3 has been limited.

Scope 1 emissions are not applicable to Solirius Reply - as a technology services company we do not produce emissions directly through owned or controlled sources.
Scope 2 emissions are calculated as Solirius Reply’s portion of energy consumption at the Nova London Office.
Scope 3 see above
Category 2 - these are the cradle to grave emissions from laptops purchased over the year using supplier published carbon emission reports
Category 4 - n/a as a technology service consultancy we do not purchase raw materials for use in delivery of our services
Category 5 - n/a we do not produce waste in our operations
Category 6 - covers business travel to client sites using the spend based method and hotel stays based on number of nights
Category 7 - employee commuting has been calculated using the average data method assuming most employees in London commute by train
Category 9 - n/a as a technology service consultancy we do not deliver tangible products to clients
Emissions reduction targets
In order to continue our progress to achieving Net Zero, we have adopted the following carbon reduction targets.
We project that carbon emissions will decrease over the next 5 years to 0 tCO2e by 2030. This is a reduction of 100%.
Carbon Reduction Projects
Completed Carbon Reduction Initiatives
The following environmental management measures and projects have been completed or implemented since the 2019 baseline. The carbon emission reduction achieved by these schemes equate to 0 tCO2e, a 0 percent reduction against the 2019 baseline and the measures will be in effect when performing the contract.
The carbon emission reductions have not yet been achieved due to increasing the size of our company nineteen-fold over the 7 years. The carbon emissions have been maintained proportionally to our company size.
The following environmental management measures and projects have been completed or implemented since the 2019 baseline.
-
Our remote working policy has significantly reduced the frequency of employee travel
-
We have implemented a hybrid working policy where there is no minimum requirement for staff to work in the office. This has reduced our per head emissions from employee commuting.
-
Implemented standard operating procedures for reduction of energy consumption.
-
A policy for sustainable business travel has encouraged employees working on client sites to choose journeys with lower carbon footprints.
-
Awarded “committed” badge by EcoVardis demonstrating our commitment to sustainability.
-
Closed our Leadenhall office, reducing our commercial office footprint.
-
Joined the Reply group will mean that we will adopt their sustainability initiatives and goals.
However, carbon emission has increased against the 2019 baseline. There are several key reasons for the increase:
-
The company has grown significantly and workforce has increased dramatically
-
Commuting has increased post-pandemic, with offices returning to normal working hours
-
Business travel has increased as our clients have returned to their offices.
-
As part of Reply, our head office is much larger than our previous office.
Future carbon reduction initiatives
In the future we hope to implement further measures such as:
-
Participating in Reply’s voluntary Group-level Net Zero target for 2030, defined on the basis of 2021 emissions data.
-
With Reply, we are currently developing a science-based Transition Plan, including the identification of the relevant decarbonisation levers across the value chain. As disclosed in the 2025 Consolidated Sustainability Statement, the outcome of this work may also lead to an update of the current Net Zero target and timeline.
-
In 2025, Reply achieved its Carbon Neutrality target for Scope 1 and Scope 2 emissions. This was achieved through the use of Energy Attribute Certificates (EACs) to cover the Group's electricity consumption and the cancellation of carbon credits equivalent to the Group's Scope 1 and Scope 2 emissions relating to district heating. This achievement does not extend to Scope 3 emissions.
