Standards & Evidence

Evidence-first sustainability work

Trail Net Zero operates on an evidence-first model. We focus on practical, documented work that helps practitioners make credible decisions and avoid greenwashing—without pretending there’s a single perfect answer for every context.

What we prioritize

  • Peer-reviewed research

    When available, we start with the strongest external evidence and translate it into usable practice.

  • Life-cycle assessment (LCA) data

    We use LCA inputs to compare options, define boundaries, and understand trade-offs.

  • Field-tested pilot results

    Real-world trials, measured outcomes, and what changed when conditions shifted.

  • Transparent documentation

    Methods, assumptions, and data sources are as important as conclusions.

  • Continuous improvement

    Standards evolve as new evidence emerges and as pilots reveal constraints and opportunities.

How members use this

Members use shared templates to document pilots, assess claims, and distinguish between proposed ideas, tested practices, and validated outcomes.

This approach supports credible decision-making and helps the community build shared knowledge over time—especially in areas where data is incomplete or context-specific.
