Baseline emissions footprint
| Baseline Year: Financial year 2022 – 2023 | ||
| Additional Details relating to the Baseline Emissions calculations. | ||
| Scope 1:
As a software as a service (SaaS) company our product is digital. We do not produce any direct emissions as a result of developing our product. Total gas emissions in our offices are set out below in the scope 2 category. Scope 2: Office energy use calculated from energy bills. Carbon Surveys of our two Bath offices, The Old Dairy (2023) and Widcombe Crescent (2019), were carried out by the West of England Combined Authority and we will be using these for our baseline data. Scope 3: Working from Home (WFH) emissions data is continuously gathered via an internal spreadsheet where employees self-report their place of work each week, the calculations are based on official ‘UK Government GHG Conversion Factors for Company Reporting’ 2023. Currently our highest priority with Scope 3 is to measure and reduce a subset of our emissions in line with the National Health Service supplier reporting requirements for 2024, these are categorised below. As a supplier of digital products we do not have emissions from upstream or downstream transportation, we work on a hybrid basis between 2 small offices and working from home – therefore our office waste is minor and we have measures in place for recycling and composting where possible (see projects section). Business travel data was obtained from our internal timesheet system and expense reports. There is specific outsourcing of our carbon emissions through our data hosting, such as AWS which disclose their carbon emissions separately. Employee Commuting – Commuting values were obtained from a staff survey in 2023 for which we got a 75% return rate. |

*Location-based method calculates emissions based on the emissions intensity of the local electricity grid area where the electricity usage occurs. We used the UK government’s ‘Greenhouse gas reporting: conversion factors 2023’: https://www.gov.uk/government/publications/greenhouse-gas-reporting-conversion-factors-2023.
**Market-based emissions are calculated based on the electricity that we have chosen to purchase, e.g. renewable energy tariff backed by Renewable Energy Certificates.
***Emissions have been calculated based on the fuel mix used to generate electricity supplied by our supplier (Pozitive Energy) between 1st April 2022 and 31st March 2023: Coal 6%; Natural Gas 61%; Nuclear 1%; Renewable 27%; Other 5%. Pozitive Energy reports that this fuel mix generates CO2 emissions at a rate of 319g/kWh. These figures were taken from https://pe.solutions/utilities/electricity/ on 23rd August 2024.
****We have not calculated market-based figures for working from home so emissions are shown as the average grid mix

Scope 3: Employee Commuting – We based current numbers off commuting values obtained from a staff survey in 2023 for which we got a 75% return rate. As the business has grown since our baseline year we have adjusted the value for the current number of FTE Employees. We will revisit the process for obtaining this data in forthcoming years. |

Current emissions reporting
| Reporting Year: Financial year 2024 – 2025 | ||

| Scope 1:
As a software as a service (SAAS) company our product is digital. We do not produce any direct emissions as a result of developing our product. Total gas emissions in our offices are set out in scope 1 category (this was reported under Scope 2 in previous years). Scope 2: Office energy use calculated from energy bills. Carbon Surveys of our two Bath offices, The Old Dairy (2023) and Widcombe Crescent (2019), were carried out by the West of England Combined Authority and we will be using these for our baseline data. Mayden has installed solar panels at our main office in Bath which became operational in July 2025 and will be taken into account in next year’s emissions reporting. Note on Scope 3: Working from Home (WFH) emissions data was gathered via an internal dashboard. The calculations are based on the official ‘UK Government GHG Conversion Factors for Company Reporting’ 2024. Employee Commuting values were obtained from a staff survey in 2023 for which we got a 75% return rate. As the business has grown since our baseline year we have adjusted the value for the current number of FTE Employees. We will revisit the process for obtaining this data in the forthcoming year. Mayden will be introducing cloud based financial reporting software in October 2025 which will streamline accurate analysis of expenses data. This year we have additionally disclosed data on waste generated at our main office in Bath. Note that the operations at the Widcombe office ceased during the year ended 31 March 2025. |

****It is impractical to calculate market-based figures for working from home so emissions are shown as the average grid mix
*****The figure for business travel includes rail which is an estimated total. We plan to put in processes for the robust collection of data on rail travel in time for future reporting years aided by our new financial reporting software.
Emissions reduction targets
In order to make ongoing progress towards achieving Net Zero, we have adopted the initial target of planning to reduce emissions by 50% by 2030. We should also be conscious that we will be making corporate acquisitions, which will need to be included in future submissions.
Emissions target progress
Despite our ongoing projects and new initiatives over the year, we have not been able to meet an ideal 10% target reduction for the year.
Carbon reduction projects
Since the carbon survey of our main office was undertaken by the West of England Combined Authority in April 2023 we have undertaken the following recommendations:
- Upgraded office lighting to LED – work undertaken in January 2024
- The amalgamation of eight on-site electricity meters to one in preparation for the solar panel project.
- Installation of solar panels in our Bath main office building, in operation from July 2025.
- In Autumn 2024 Mayden was partnered with the University of Bath School of Management. A group of masters students joined us for a 6 week project. They undertook a double materiality assessment to help us understand carbon reduction opportunities within the business.
Continuing projects include:
- Promotion of the cycle to work scheme.
- Responsible disposal of electronic waste.
- Composting office food waste.
- Supporting employees to work from home.
- The Sustainability Working Group continues to look for sustainable initiatives and opportunities.
New projects include:
- Soft plastics recycling scheme utilising local recycling points.
- Creation of a new staff commuting survey.
- The addition of a garden pollinator at the Bath main office.
