About the publication
The Apparel Impact Institute’s Energy and Carbon Benchmark complements current methodologies by offering data on specific processes within facilities, allowing for year-on-year performance tracking and objective comparisons across facilities and regions. It is designed to serve as a transparent, independent reference that helps brands, manufacturers, and stakeholders align on consistent metrics and drive collective progress toward industry-wide decarbonization.
Building on existing data and tools, the benchmark consolidates existing GHG performance data from verified sources such as the Higg Index, technical experts, and direct mill assessments. At this stage, it functions as a voluntary reference point, not a compliance standard, intended to benefit manufacturers by highlighting strong performers and enabling data-driven decision-making. Ultimately, it supports a unified, industry-aligned approach to reducing emissions across the textile supply chain.
Version 1.0 of the Carbon and Energy Benchmark has now been released. Further information on using the tool can be found below.

Technical review committee
With the publication of V1, Aii is sunsetting the Technical Review Committee and creating a new advisory body, the Benchmark Advisory Committee (BAC), that will provide ongoing technical and strategic guidance. We are currently seeking potential members of the BAC with expertise in energy systems, emissions estimation, methodology development, and benchmark creation to ensure the review process is robust and well-informed. The review is intended to be an ongoing process to ensure the benchmark methodology remains accurate and up to date.
If you are interested in joining the Benchmark Advisory Council, please email us at benchmark@apparelimpact.org with the subject line “Carbon Benchmark Advisory Council.” In your message, briefly describe your relevant experience and interests in this area. Applications will be open through April 11, 2026.

Informational Webinar
Recorded in 2025, this webinar provides an overview of the draft benchmarking methodology and process as they existed at that stage of development. It also explains how the tool compares facilities with different production mixes, fuel choices, and process configurations, and what an individual benchmark score means for a facility.
