Scope 3 Emissions

Overview

Scope 3 emissions are indirect greenhouse gas emissions resulting from activities across the value chain, outside the direct control of the developer. These emissions are often under-reported due to limited sector-specific guidance and inconsistent application of the GHG Protocol’s Scope 3 Standard.

Mainer Associates provides expert consultancy to help clients manage and reduce Scope 3 embodied carbon emissions throughout the development lifecycle.

Our Approach

    • Support for post-contract teams to meet client-defined embodied carbon targets.

    • Development of embodied carbon strategies aligned with net zero objectives.

    • Deployment of on-site software tools for real-time carbon tracking and reporting.

    • Integration with lifecycle assessment (LCA) workflows.

    • Assistance in drafting development briefs and contract documentation that embed carbon reduction requirements.

    • Early-stage scoping of offsetting strategies and low-carbon design options.

Net Zero Delivery

As-Built Whole Life Carbon (WLC) Assessment

  • Update of pre-contract datasets to reflect final embodied carbon totals.

  • Post-completion reporting including operational carbon forecasts.

Embodied Carbon Strategy

  • A tailored roadmap for procurement and construction phases.

  • Identification of carbon-saving opportunities that are:

    • Cost neutral

    • Programme neutral

    • Technically viable

    • Equal in quality

Supply Chain Engagement

Early engagement with the supply chain is critical to achieving meaningful carbon reductions. Mainer Associates facilitates collaboration between contractors and clients to track and present opportunities through agreed platforms, ensuring transparency and alignment with sustainability goals.
