Stiona Software Ltd. is committed to achieving net zero emissions by 2050.
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.
Building Heating – 0.79 tCO2e
Purchased Electricity: 3.26 tCO2e
We purchase only digital services and have no inbound transportation of goods; therefore upstream transportation and distribution is not applicable.
Calculated from .gov.uk Greenhouse gas reporting: conversion factors 2024.
Waste generated is "Household residual waste" - in the form of general waste from staff in the office. This is processed by Belfast City Council.
Approx waste generated for landfill = 5 kg per week * 52 weeks = 260kg
Landfill kgCO2E 497.04416 per tonne
(260/1000) X 497.04416 = 129.231 kg = 0.13 tCO2e
In addition, general waste recyclables are separated and also collected by Belfast City Council.
Approx waste generated for recycling = 5 kg per week * 52 weeks = 260kg
This is roughly 50/50 paper and board / plastics which both have 4.68568 kg CO2.
(260/1000) X 4.68568 = 1.2183 kg = 0.0012 tCO2e which is negligible.

In order to continue our progress to achieving net zero, we have adopted the following carbon reduction targets.
Cloud Computing : Exclusive use of cloud platforms and services, reducing our carbon footprint by reducing hardware needs. Cloud provides use energy efficient data centres which optimise resources and enable virtual working and collaboration.
Reduce energy consumption : Optimising business thermostatic controls, promote virtual meetings, energy efficient lighting, reduce output devices for paperless office.
Reduce travel for business : Optimising cloud and virtual meeting technology to reduce travel emissions.
Electric Company cars : Company cars are all battery electric Executive vehicles with zero emissions (as in UK Government GHG Conversion Factors for Company Reporting)
Paperless office : Monitor the implementation of the paperless office to reduce paper and electricity consumption.
Waste Management : Implement waste reduction strategies and maximise recycling opportunities.
Employee engagement : Educate and engage employees in sustainability efforts.
We project that carbon emissions will decrease over the next five years to 18.87 tCO2e by the start of 2030. This is a reduction of approximately 26%.
The following environmental management measures and projects have been completed or implemented since the 2024 baseline. The carbon emission reduction achieved by these schemes equate to 0.34 tCO2e per month, an approximately 6% reduction against the 2024 baseline and the measures will be in effect when performing all contracts.
Implementing energy efficient technologies: increasing the use of energy efficient appliances, cloud technologies including virtual working.
Encouraging energy efficient behaviour: promoting conscious energy consumption with staff with processes and training.
Employee incentives: Employee energy saving initiatives including bike to work promotions and salary schemes for electric car purchases
In the future we hope to implement further measures such as:
Moving to a virtual working model – reducing office space required and energy consumption.
This Carbon Reduction Plan has been completed in accordance with PPN 006 and associated guidance and reporting standard for Carbon Reduction Plans.
Emissions have been reported and recorded in accordance with the published reporting standard for Carbon Reduction Plans and the GHG Reporting Protocol corporate standard and uses the appropriate government emission conversion factors for greenhouse gas company reporting.Government conversion factors for company reporting of greenhouse gas emissions
Scope 1 and Scope 2 emissions have been reported in accordance with SECR requirements (where required), and the required subset of Scope 3 emissions have been reported in accordance with the published reporting standard for Carbon Reduction Plans and the Corporate Value Chain (Scope 3) Standard.
This Carbon Reduction Plan has been reviewed and signed off by the board of directors (or equivalent management body).
