Carbon Reduction Plan

Decarbonisation Plan for GreenLight Engineering Group – 2025 

GreenLight Engineering Group is committed to reducing its direct and indirect greenhouse gas emissions. Our overarching goal is to embed sustainability across the three businesses that make up our group—GreenLight Fit Out, GreenLight Facility Management (FM), and GreenLight Renewables. 

This commitment to sustainability is being systematically implemented through the calculation and reduction of our carbon footprint. After our initial attempt at assessing our carbon footprint, we undertook a more thorough evaluation to include all relevant and material emission categories. Our first carbon footprint calculation only included Scope 1 and Scope 2 emissions, but as a first attempt it did not fully reflect the impact of our operations. With our 2024 recalculation, we expanded our scope to include Scope 3 emissions, which, as expected, account for the majority of our emissions. Since 2024 is a more comprehensive calculation, it is our new baseline. 

While we have established a strong foundation for tracking our carbon footprint, our next steps are to implement additional measures that will systematically reduce emissions across all areas, setting us on a clear path toward achieving Net Zero by 2050. 

Current Emissions Overview: 

Our carbon footprint in 2024 has been calculated to include all relevant Scope 1, Scope 2, and Scope 3 emissions categories. A key part of this process involved identifying data gaps, relying on estimations where necessary, and improving our approach by requesting lifecycle assessment (LCA) data directly from suppliers. This has provided a clearer picture of our emissions profile, enabling the development of a more targeted decarbonisation plan. 

The current baseline of our carbon emissions is as follows: 

• Scope 1 Emissions: 14.38 tCO2e 

• Scope 2 Emissions: 3.40 tCO2e 

• Scope 3 Emissions: 956.26 tCO2e  

Our emissions per employee is 41.51 tCO2e and emissions per £1m of revenue is 125.82tCO2e. 

While we will always try meet our reduction targets, in the event that our total emissions rise due to anticipated business growth and the increase in purchasing materials and services, our decarbonisation efforts will be evident in our reducing intensity ratios. This means that even if our total carbon footprint may increase in some areas, our efficiency in reducing emissions relative to revenue and employee numbers will improve as we decarbonise our operations. 

 

Decarbonisation Goals and Strategy: 

Our decarbonisation objectives are ambitious but achievable. We have set clear reduction targets over the coming years to guide our path toward Net Zero by 2050: 

• 15% overall reduction by 2035 

• 40% reduction by 2040 

• 65% reduction by 2045 

In the first year of our decarbonisation efforts (2025), we aim to reduce our total carbon emissions by 20 tCO2e. This reduction will be primarily achieved through a variety of measures aimed at reducing Scope 1 and Scope 3 emissions. 

 

Decarbonisation Measures and Actions: 

Scope 1 Emissions: Our current focus in reducing Scope 1 emissions is on transitioning more of our fleet to more sustainable vehicles. Over 50% of our fleet is now made up of hybrid or electric vehicles (EVs), and we are committed to converting the entire fleet as car leases come up for renewal. We will also monitor vehicle usage closely to ensure optimal efficiency. 

Additionally, as we operate from the historic Merton Abbey Mills in Wimbledon, we are working with our landlord to improve the energy efficiency of the building. The building is poorly insulated, and we currently rely on gas heating to regulate temperature. With the support of our landlord, we aim to implement improved temperature controls to minimise heating and cooling needs. 

Scope 2 Emissions: To reduce energy consumption and Scope 2 emissions, we have already worked with our landlord to implement measures such as switching to LED lighting and installing motion-sensor bathroom lights. We will continue to build on these efforts with an appliance audit to identify and replace inefficient equipment when it comes up for renewal. Additionally, we are exploring the potential for solar PV installation on-site at our head office to offset some of our electricity usage with renewable energy. 

We are also collaborating with our landlord to enhance energy efficiency across the entire estate, including both facility and equipment improvements within our building. 

Scope 3 Emissions: The majority of our emissions come from Scope 3, particularly from purchased goods and services, which account for 93% of our total carbon footprint. Our approach to reducing these emissions includes: 

• Engaging suppliers: We are working with suppliers to better understand their emissions profiles through supplier questionnaires. This will allow us to gather data on their products’ life cycle emissions (LCAs) and identify opportunities to shift toward more sustainable products and services. 

• Procurement practices: We will actively integrate sustainability into our procurement process by prioritising lower-carbon alternatives and energy-efficient technologies for our projects and services. This will also involve a continued push to educate both our suppliers and customers on the benefits of more sustainable choices. 

• Internal collaboration: Cross-departmental workshops will focus on educating our teams about the importance of reducing carbon-intensive products and services in favour of more sustainable solutions. We are also updating out finance and data management processes to improve the efficiency of gathering information for improving the accuracy of our carbon footprint calculations. 

We are committed to regularly reviewing and updating our procurement practices to ensure that we are consistently able to pursue the most sustainable options, both environmentally and financially. We aim to recommend the most sustainable alternatives to our clients, helping to reduce both our own emissions and those of our clients. 

 

Waste and Water Management (Scope 3): 

We are taking a number of measures to manage waste and water usage in a sustainable manner: 

• Waste management: In 2024, we began separating waste on-site to ensure it is properly processed by our waste management supplier. Within our corporate operations we have also started separating organic waste, which will be processed through a worm farm once the landlord installs it on the estate. Our goal is to continue to achieve zero waste to landfill each year. 

• We will also begin monitoring the waste generated on project sites to gain a clear understanding of our actual waste production. This will enable us to explore and implement sustainable waste management solutions where feasible. 

• Water use: In response to the increased awareness of water scarcity, with our landlord, we are exploring the possibilities of low-flow taps and low-flush toilets to be installed in the office restrooms, contributing to reduced water usage. We are also exploring other water-saving technologies across all the facilities that we manage like water butts and greywater systems- which will not reduce our own carbon footprint but that of our clients. 

 

Tracking and Reporting: 

GreenLight has committed to continuous improvement in tracking our progress towards our decarbonisation goals. Key components of this process include: 

• Annual Carbon Footprint Reporting: We will report our progress on carbon reductions annually, including a comprehensive carbon reduction report that tracks progress against our 2035, 2040, and 2045 targets. 

• Employee Involvement: We will ensure that all staff are kept informed about our decarbonisation goals and progress. We have regular “All Hands” meetings to provide updates, encourage feedback, and keep everyone involved in our sustainability journey. 

 

By implementing this Decarbonisation Plan, GreenLight will continue to reduce its carbon footprint in line with our long-term sustainability goals (see our sustainability goals). Through a combination of strategic actions, continuous monitoring, and collaboration with our suppliers and clients, we are confident in our ability to contribute to a more sustainable future and meet Net Zero by 2050 latest.
