Baseline year: 2025
Net Zero Emissions: by 2050
Baseline Emissions Footprint
Baseline emissions are a record of the greenhouse gases that have been produced in the past and were produced prior to the introduction of any strategies to reduce emissions. Baseline emissions are the reference point against which emissions reduction can be measured.
Operational greenhouse gas emissions reported in this section are classified according to the Greenhouse Gas (GHG) Protocol1 into Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased electricity), and Scope 3 (other indirect emissions across the value chain such as business travel and waste management).
The following activities have been included under each scope for Siren’s 2025 baseline:
Scope 1: Company vehicle fuel use
Scope 2: Office electricity consumption (Électricité du Liban)
Scope 3: International flights; paper consumption; drinking water consumption
Emissions are calculated using activity data (e.g., fuel consumption, electricity use, travel activity) multiplied by relevant emission factors in accordance with the UK Government GHG Conversion Factors for Company Reporting. Final emissions are reported as tonnes (t) of CO₂ equivalent (e).
Baseline year emissions 2025 | |
Emissions | TOTAL (tCO2e) |
|---|---|
Scope 1 | 14.89 tCO₂e |
Scope 2 | 21.94 tCO₂e |
Scope 3 | 27.1 tCO₂e |
Total emissions | 63.9 tCO₂e |
As seen by the figures above, total operational emissions in 2025 are primarily driven by international business travel and electricity consumption, which together account for the majority of Siren’s carbon footprint. Emissions from direct fuel use represent a smaller but still material share, while those associated with office consumables such as paper and water remain negligible in comparison.
Emissions reduction targets
In order to continue our progress towards achieving Net Zero emissions by 2050, Siren Associates has adopted a “reduce first, offset residual emissions” approach, aligned with international best practice and UK Government requirements.
Our carbon reduction priorities focus on both direct operational reductions and compensatory offsetting measures, including:
Offsetting flight-related emissions through verified reforestation initiatives.
Supporting nature-based carbon removal through tree planting activities and ecosystem restoration.
Reducing travel-related emissions by prioritising remote delivery models, local recruitment, and direct flights where travel is required.
Improving energy efficiency through measures such as LED lighting and responsible energy consumption practices.
Reducing resource consumption, including continued efforts to minimise paper use and transition to digital systems.
Supporting clients’ transition to renewable energy, including solar energy installations, contributing to wider decarbonisation impacts.
Based on our 2025 baseline of 63.9 tCO₂e, and taking into account ongoing operational efficiencies and mitigation measures already demonstrating positive trends (e.g. reduced flights per staff and lower emissions intensity), we project that:
Carbon emissions will decrease to approximately 50 tCO₂e by 2030, representing a reduction of ~22% against the 2025 baseline.
This projection reflects realistic, incremental reductions in operational emissions, particularly from travel and resource use, while maintaining programme delivery capacity in complex operating environments.
Residual emissions will continue to be addressed through targeted offsetting measures, with a view to strengthening and formalising our carbon reduction strategy over time.
