Scope 1 Emissions

Smart Air UK does not generate Scope 1 emissions, as we do not own or operate any fuel-burning equipment or vehicles. As a tenant, our office energy usage falls under Scope 2, while transport, distribution, and supplier emissions are accounted for under Scope 3.

Scope 2 Emissions (UK Operations)

  • Headcount: 6 employees
  • Office Energy Use: Our rented building promotes energy-saving practices, including signs to ask for lights to be switched off when not in use, centralised heating, and waste separation.
  • Employee Commuting: Hybrid work model with public transport and walking-only travel when in the office, minimising transport emissions.
Total Scope 2 2,344.93 kg CO₂e
Office Energy Lighting Usage (kWh) 109.52
Office Energy Heating Usage (kWh) 32.27
Office Energy Permanent Equipment Usage 684.48
Office Energy Temporary Equipment Usage 328.55
Remote Work Heating/Cooling Usage 1,190.11

Scope 3 Emissions (UK Operations & Supply Chain)

Upstream
  • Freight & Logistics: Evergreen Freight follows ISO14064-1:2018 standards and has a Greenhouse
  • Gas Inventory Team working on annual carbon reduction targets.
  • Warehousing (Essex & London): We use 3PL but emissions aren’t measured. Our calculations are based on the m3 of our pallet storage
  • Waste & Packaging: We actively reuse packing materials, recycle toner cartridges, reduce paper use, and collect cardboard waste for recycling.
Total Scope 3 Upstream 27,010.70 kg CO₂e
Shipping Cost of sales - Freight 20,093.54
Warehouse Warehouse (3rd party) 2,155.01
Business Business (meals / travel) 4,757.39
Waste Management Recycled Packaging Use 0.03
Commute Public Transport 4.74

Shipping and warehouse data based on actual weight and dimensions. Commute is based on staff surveys. Business meals and waste management are estimates from £ spent

Downstream
  • Royal Mail aims for Net Zero by 2040, using 5,000+ electric vans and green logistics. Currently, they estimate an average emission of 0.218 kg CO₂e per parcel
  • FedEx is transitioning its parcel fleet to electric and provides carbon tracking tools. We are therefore using exact emission data for our deliveries
  • Mango Logistics were used for the ‘last-mile’ electric distribution into London as part of the Mayor’s School Filters Programme (see below).
Total Scope 3 Downstream 3,537.34 kg CO₂e
Royal Mail Transport and delivery 513.98

How we calculate our emissions

This emissions report focuses on the categories required for public sector contracts, ensuring compliance with reporting standards while providing an accurate reflection of our operational footprint. While broader corporate emissions tracking is valuable, this report prioritises the essential data relevant to procurement criteria.

Additional emissions categories may be explored in future sustainability assessments as our environmental strategy evolves.

To ensure accuracy, we have prioritised actual data over broad estimates when calculating emissions:

  • Royal Mail, shipping, and warehouse emissions are determined by weight, dimensions, and item quantity, ensuring precise freight calculations
  • FedEx and Mango couriers are able to provide actual figures based on mileage
  • Commuting emissions are directly based on employee surveys, rather than industry averages
  • Office energy use and remote work emissions are calculated using exact employee hours, factoring in heating, lighting, and equipment energy consumption
  • Business meals and travel, and recycled packaging use are calculated based on spend (£ spent) rather than assumed impact

This approach ensures our emissions reporting reflects real operational impact rather than inflated generic estimates.

In this reporting period, we were awarded the Mayor of London’s School Filters Programme to supply air filters to 200 schools in some of the most polluted areas across London. This contract significantly increased our warehouse, shipping and distribution emissions compared with 2024/25. By choosing Mango Logistics as our delivery partner, 94% of deliveries were completed using electric vehicles. We estimate this reduced emissions from distribution by around 70% compared with using equivalent diesel vehicles.

Future reductions: planned structural changes

Building on the measures already implemented, we will continue to identify opportunities to reduce emissions across our operations and supply chain. Particular focus will be placed on improving logistics efficiency, reducing transportation emissions intensity and evaluating lower-impact product designs.

Key emission-reducing initiatives include:

  • Consolidated B2B and public sector deliveries - As our sales mix increasingly includes larger business and public sector contracts, we will seek to reduce the number of individual deliveries through greater use of consolidated shipments. This approach has the potential to improve vehicle utilisation and reduce emissions per unit delivered.
  • Low-emission logistics partnership – For larger public sector contracts, we will partner with local EV logistics company to offer last-mile delivery using electric vehicles and cargo bikes where appropriate. These measures are intended to improve delivery efficiency and support reductions in downstream transportation emissions associated with product distribution.
  • Product design and material optimisation - In 2026, we will launch the Airbon range of air purifiers. Approximately 95-97% of the product weight consists of wood-based material, reducing reliance on plastic and metal components compared with conventional product designs. As the range is introduced, we will assess its impact on emissions associated with purchased goods and materials and identify opportunities for further reductions.
  • Packaging and circularity improvements - We will continue to review packaging materials and processes to minimise waste and encourage reuse where practical, supporting broader resource-efficiency objectives across the business.25 onwards.

As these initiatives are implemented and further data becomes available, we will continue to monitor their impact and incorporate measurable emissions reductions into future reporting periods.

Carbon reduction measures

To reduce emissions and progress towards Net Zero, we commit to the following actions:

  • Supply chain optimisation – Partnering with logistics providers that prioritise low-carbon transport, electric vehicle fleets, and sustainable freight solutions. We will also collaborate with our warehouse partners to implement carbon tracking tools for improved emissions monitoring.
  • B2B growth strategy – Expanding our business-to-business operations to reduce distribution emissions by consolidating shipments - sending more products to single destinations instead of multiple individual addresses.
  • Energy-efficient office practices – Continuing our commitment to hybrid working, waste separation, and energy-saving initiatives, such as promoting refillable water bottles and bamboo travel cups to reduce single-use waste.
  • Ongoing emissions monitoring – Strengthening engagement with our shipping and distribution partners to track, report, and actively reduce emissions on an annual basis.
  • Scope 3 offsetting initiatives – We have partnered with Carbon Footprint to support certified tree-planting projects, offsetting 4 tonnes of CO₂e emissions, primarily covering our shipping freight emissions (2,508.25 kg CO₂e) which we will be unable to reduce via this plan. This initiative substantially decreases our overall carbon footprint and aligns with our commitment to responsible environmental action.

Monitoring and governance

Our team will review and update our Carbon Reduction Plan annually. We commit to full transparency in tracking our carbon footprint and ensuring alignment with NHS sustainability targets. Further details on our supply chain sustainability initiatives can be found here.
