Commitment to achieving net zero

Astroscale Limited (ASUK) is committed to achieving net zero emissions by 2040.

Astroscale was founded with the core mission to make space more sustainable, and we are committed to sustainability on Earth. ASUK is committed to operating in space and on Earth for the benefit of future generations. These two missions are connected at the core; a sustainable space environment is a key enabler for sustainability on Earth.

Satellites are an integral part of climate monitoring, more than half of Essential Climate Variables can only be tracked via satellites, per the Global Climate Observing System. Satellite data also plays a critical, enabling role in services, planning, and damage mitigation across disaster response, security of food and other critical resources, identification of illegal activity, border security, and weather prediction.

By delivering on our mission to achieve the safe and sustainable development of space, we are also supporting sustainability on Earth.

Emissions Reporting

Baseline emissions have been calculated by taking the total ASUK emissions for Scopes 1, 2, and 3. Our total emissions for Scope 1 and 2 emissions are calculated in line with Greenhouse Gas Protocol and PPN06 standards and guidance, more details on methodology can be provided upon request. The Scope 2 number reported is based on the location-based calculation method. The required Scope 3 emissions categories have been calculated for the UK as follows:

1. Upstream transportation and distribution: emissions are based on value of goods, weight transported, distance travelled, and relevant UK government conversion factors

2. Waste generated in operations: emissions are based on building data provided by Harwell Campus

3. Business travel: emissions are based on the method of travel, the distance travelled, and relevant UK government conversion factors

4. Employee commuting: emissions are based on employee commute distances, average days in the office, and relevant UK government conversion factors

5. Downstream transportation and distribution: emissions are based on value of goods, weight transported, distance travelled, and relevant UK government conversion factors

Emissions reduction targets

ASUK is dedicated to reducing operational emissions, whether direct or indirect. To achieve this, ASUK is focusing on reducing energy consumption and emissions of buildings and manufacturing efforts, prioritising renewable sources for energy supply, decreasing high emissions business travel, and implementing project-specific initiatives across programmes.

In order to continue our progress towards achieving net zero, we have adopted the following carbon reduction targets:

We project that carbon emissions will decrease over the next five years to 3778.9 tCO2e by 2030. This is a reduction of 25% with a further planned reduction goal of 50% reduction (totalling 2519.3 tCO2e) by 2035. This falls in line with ASUK’s goal to achieve net zero emissions by 2040.

Completed carbon reduction initiatives

Though ASUK has not formally calculated or reported on emissions prior to the 2024 baseline year, sustainability initiatives in space and on Earth have always been a core part of company strategy. The following environmental management measures and projects have been completed or implemented:

• The selection of Harwell Campus for our UK office offers modern, energy-efficient infrastructure that supports ASUK’s carbon reduction goals to include:

  • Modern insulation to maximise thermal efficiency

  • Advanced HVAC systems that adapt to seasonal and occupancy needs

  • Smart Lighting with energy efficient LEDs

  • EV charging stations

  • Recycling and food waste disposal

  • Commitment to Biodiversity Action Plan

  • Access to green travel options like bike share programmes and discounted bus tickets

• Integration of renewable energy sources, electricity supply is currently 70% sourced from renewable energy, to proactively decrease our Scope 2 emissions

• Choice to shift away from gas-based heating and powered vehicles in favour of electric-power

• Operation under a hybrid work policy (min. 2 days per week), reducing commute-related emissions by up to 60% while supporting employee flexibility and wellbeing

• Implementation of an Environmental Policy with annual review, including:

  • Environmental Protection

  • Energy Conservation

  • Procurement

  • Pollution Prevention

  • Health and Safety

  • Purchasing

  • Waste Reduction

  • Carbon Footprint Reporting

  • Chemicals

  • Cooperation and Compliance

  • Education

  • Commitments

• Prioritise low emissions manufacturing equipment and materials, including electric-operated cranes in the cleanroom.

• Prioritise UK suppliers and subcontractors where possible to reduce distance required for transport of materials

Future Carbon Reduction Initiatives

In line with our founding principles of enabling a more sustainable space environment, which contributes to sustainability on Earth, ASUK’s operational and technical teams continuously seek to integrate emissions-conscious design, delivery, and procurement decisions into our sustainability mission on Earth. To achieve our carbon reduction goals, ASUK is focusing on reducing emissions across Scopes 2 and 3.

ASUK is actively developing new initiatives and tools to further reduce and track carbon emissions in the coming years, including:

• Operate under fully Renewable Energy for Scope 2 emissions by 2035

• Institute an Employee Commuting Survey to accurately track carbon emissions spent while traveling to and from Harwell Campus

• Integrating Logistics Tracking for upstream and downstream transport and distribution into SAP platform to increase the accuracy of emissions transport and delivery related emissions.

• Beginning in Quarter 1 of 2026, begin internal Quarterly Review of an Emissions Dashboard

• Begin cross-functional working group to implement carbon cautious practices and counting throughout operational teams

• Creation of carbon-conscious travel policy in line with strategic initiatives

• Obtain certifications in ISO 14001’Environmental Management Systems’ and Science Based Targets initiative (SBTi)

• Engage key suppliers to align with SBTi, aiming for at least 67% of Scope 3 emissions to be covered by supplier-set targets

• Emphasise sustainable, low-carbon procurement practices across programmes

• Our net zero ambitions will also drive efficiency, innovation, and collaboration across our wider supply chain and partners as we set goals to define project-specific initiatives across all programmes

• Plans for any future expansion or significant capital investment to consider emissions impact upfront

• Actively engaging with and lobbying Harwell Campus for more frequent, reliable local bus services to encourage further use of public transport
