The HALO Methodology

We know it's hard to understand what is best for the planet and it can be difficult to tell the good projects from the bad. That's why we built the HALO assessment matrix.

We have carefully assessed every project we fund using this tool so you can rest assured your money is having the maximum impact.

We use a selection of the most respected best practice guides to assess the projects key impacts across our 4 key areas:


  • Planetary Pressures adapted Human Development Index

  • Multi-Dimensional Poverty Index

  • Project incentives to build resiliency and sustainable livelihoods


  • Project Drawdown climate solution ranking

  • Oxford Carbon Offsetting Principles

  • TSCVM Offsetting Principles

  • Carbon credit vintage


  • AICHI Biodiversity Goals

  • Kew Tree Planting Principles

  • Impact on consumption

  • Impact on pollution


  • AICHI Biodiversity Goals

  • Impact on consumption

  • Impact on pollution

We then assess our projects against the United Nations 

Sustainable Development Goals.

We score our projects against all of these key indicators then balance our portfolio to optimise your impact.

We go the extra mile to ensure the projects we fund don't create broken incentive systems or have unintended consequences.

We do the hard work so you don't have to.
