Our Net Zero Commitment

Mammoth is committed to achieving Net Zero carbon emissions by 2050. This commitment covers our emissions from direct energy use (Scope 1), indirect energy use (Scope 2) and transport. It does not currently include emissions from refrigerant gas loss or Scope 3 supply chain activity; we are working to establish a methodology for Scope 3 measurement as part of our ongoing carbon reduction journey.

Our carbon footprint calculation follows the international Greenhouse Gas Protocol and UK Government guidance. Figures are based on our best available information and are reviewed annually.

Emissions Baseline (2025/26)

Emission Source	Scope	tCO2e
Energy use in buildings	Scope 2	4.10
Fleet fuel consumption	Scope 1	0.00
Total		4.10

 

Waste and Water Management

Reducing the impact of waste we generate

Waste management is central to our carbon reduction plan. Landfill is the most carbon-intensive method of waste disposal and we are committed to reducing and segregating waste to minimise our environmental impact.

Action Plan:

Develop and implement a waste policy [In Progress]

We are developing a waste policy aligned to the waste hierarchy to communicate our intent clearly to staff and stakeholders.

Introduce segregated mixed recycling bins [In Progress]

Internal and external recycling infrastructure is being introduced across our Belfast and London offices.

Explore food recycling collection services [In Progress]

We are scoping the feasibility of a food waste scheme supplemented by internal and external food waste bins.

Improve bin signage [In Progress]

Clear, consistent signage is being introduced to make correct waste disposal straightforward for all staff.

Implement a waste reduction campaign [In Progress]

An employee engagement campaign is being developed to embed sustainable waste behaviours across the organisation.

 

Reducing waste and avoiding single-use items in our work

We are committed to reducing single-use items across the products and services we develop and the materials we procure, sending a clear signal to clients and stakeholders about our sustainability values.

Action Plan:

Conduct a Life Cycle Analysis of products and services [Not Started]

We will commission an LCA to quantify the environmental impact of our key services and identify areas for improvement.

 

Reducing the use of consumables

Reducing paper consumption has been a longstanding priority for Mammoth. We are building on existing progress to formalise our commitment and extend it across all consumables.

Action Plan:

Encourage a reduction in printing and photocopying [In Progress]

A formal commitment to reduce printing is being embedded in our office operations policy.

Use recycled paper across the business [In Progress]

Where printing is necessary, we are transitioning to recycled paper stock across both offices.

Develop a commitment to becoming a paper-free business [In Progress]

We are undertaking an initial review of paper usage to establish a baseline and set a target date for paper-free operations.

Switch to sustainably sourced materials [In Progress]

We are reviewing our supplier base to ensure consumables are sourced from sustainable, FSC-certified or recycled sources wherever possible.

Put a policy in place to avoid single-use items [In Progress]

A single-use item reduction policy is being developed to formalise our commitment and set measurable targets.

 

Travel and Transport

Reducing the impact of our business travel

We recognise that business travel contributes to our carbon footprint and are committed to reducing unnecessary travel while supporting effective client and stakeholder engagement.

Action Plan:

Develop a travel policy [In Progress]

A travel policy incorporating the sustainable travel hierarchy is being developed to guide staff decision-making.

Implement the sustainable travel hierarchy [In Progress]

Staff are being encouraged to prioritise lower-carbon travel options and to consider virtual alternatives before committing to in-person travel.

Set a target to reduce business travel [In Progress]

We will establish a baseline and set annual reduction targets for business travel mileage and associated emissions.

Reduce the need for in-person site visits where possible [In Progress]

We are actively promoting the use of video conferencing for client meetings and project reviews where an in-person visit is not essential.

 

Maximising the benefits of remote and hybrid working

Mammoth operates a hybrid working model across our Belfast and London offices. We are committed to maximising the carbon and wellbeing benefits of flexible working while ensuring our teams remain connected and productive.

Action Plan:

Identify ways to support and manage remote workers effectively [In Progress]

We are reviewing our remote working infrastructure to ensure staff have the tools and support needed to work productively from home.

Increase the use of video conferencing software [In Progress]

We are standardising our video conferencing platform to reduce the need for travel and improve the remote working experience.

Review software requirements to support agile working [In Progress]

We are ensuring our software stack supports seamless collaboration between office and remote workers.

 

Supporting employees with sustainable commuting options

We are committed to making it easier for our staff to commute sustainably, reducing both the carbon impact and the cost of getting to work.

Action Plan:

Understand current commuting patterns and motivations for change [In Progress]

We will conduct an employee survey to establish commuting baselines and identify the incentives most likely to drive sustainable behaviour change.

Promote a car-sharing scheme [In Progress]

We are exploring the introduction of a formal car-sharing scheme with associated incentives for participating staff.

Promote and incentivise public transport [In Progress]

We are reviewing public transport access from our offices and will explore travel pass loan schemes to reduce the cost barrier for staff.

Install accessible, secure cycling storage [In Progress]

We are assessing the feasibility of improved cycling infrastructure at both offices, including secure storage and end-of-trip facilities.

Introduce a Cycle to Work scheme [In Progress]

We are exploring the introduction of a Cycle to Work scheme to make cycling a more accessible and affordable commuting option for staff.

 

Commitments and Governance

Driving and delivering our sustainability commitments

Mammoth is committed to ensuring our carbon reduction commitments are actively managed rather than aspirational. We are putting in place the governance structures needed to deliver meaningful progress.

Action Plan:

Appoint a senior operational lead for carbon reduction [In Progress]

A named senior lead will be responsible for driving delivery of this plan, supported by the Senior Leadership Team.

Commit to annual progress reporting [In Progress]

We will publish an annual update on our carbon reduction progress, maintaining transparency with clients, stakeholders and the public sector.

Establish a process to manage and monitor progress [In Progress]

A governance framework including regular review meetings and a carbon reduction dashboard is being developed.

 

Improving employee engagement on sustainability

Our people are central to delivering our carbon reduction commitments. We are investing in building sustainability knowledge and green skills across the organisation.

Action Plan:

Include carbon reduction commitments in employee objectives [In Progress]

Sustainability targets will be embedded in relevant staff performance objectives to ensure accountability at every level.

Include sustainability awareness in employee inductions [In Progress]

New starters will be introduced to our carbon reduction commitments and their role in delivering them as part of the induction process.

Offer sustainability and climate change awareness training [In Progress]

We will provide access to Carbon Literacy training or equivalent to staff across the business.

Develop a long-term employee engagement plan for sustainability [In Progress]

A structured engagement plan aligned to the lifetime of this Carbon Reduction Plan is being developed to sustain momentum and embed sustainable behaviours.
