Dr Jim Goddin, Director

I have spent two decades connecting materials engineering with the economics of resource use. In 2015 I co-developed the Material Circularity Indicator (MCI) with the Ellen MacArthur Foundation, while leading collaborative R&D at Granta Design in Cambridge. Over the same period I built supply-risk metrics for critical materials, including a compositionally aggregated method for assessing whole bills of materials.

Since moving to New Zealand I have led circular economy work at thinkstep-anz, taking the MCI from method to market: verified MCI results in Environmental Product Declarations, the MCI Pro tool, and the 2024 MBIE report on the emissions and jobs impacts of circular approaches in New Zealand. My recent paper in the Journal of Circular Economy sets out practical experience of publishing circularity indicators in EPDs.

I am a contributing author of ISO 59020:2024 and a designated national expert to ISO/TC 323. I sit on the Green Building Council of Australia's Circular Strategies Expert Reference Panel and the advisory panel of ResiLoop, the Australian resilient flooring product stewardship scheme.

  • Hoskins Circular Limited is a New Zealand registered company based in Christchurch. Hoskins began as a UK consultancy in 2020 and now works with clients across New Zealand, Australia, the UK and Europe. Where a project needs more hands, I bring in trusted specialist associates.

    • Manufacturers who need circularity or recycled content claims that stand up to scrutiny;

    • Building and fitout teams working on circular strategy;

    • Procurement and supply-chain leads assessing material supply risk;

    • Government agencies, industry associations and professional bodies shaping policy, standards and training.

  • Recycled content claims. An independent, third-party statement on an Australian construction product manufacturer’s ISO 14021 recycled content claims, used to support its Environmental Product Declarations.

    Circular strategy. A circular economy strategy for another Australian construction product manufacturer, aligned with its key market and regulatory drivers, with an assessment of its data readiness for upcoming reporting and declaration requirements.

    Composites sector framework. The Composites Design for the Environment Framework, guiding New Zealand’s composites sector on circular product and business-model design.

    The Australian projects were delivered at thinkstep-anz.

  • Evidence first. Every figure traced to a primary source, every assumption stated. My standard is work that holds up to a hostile expert reader.

    Materials and economics. I treat circularity as a question of resource security, risk and value. Environmental gains follow.

    Plain English. Clear findings a board can act on, with the technical detail available for those who want it.

  • On long family drives to Orkney, our dad invented a game about a character called Hoskins. Everyone took turns adding to his adventures, and the best stories came when people picked up each other's ideas and ran with them. Good circular business models work the same way: open collaboration, built on together, without a fixed plot.
