Thesis

Industrial Returns With Structural Conservation & Carbon Upside

This is not impact-adjacent investing. Core returns are anchored by genuine industrial and commercial cashflows scaling to US$5.10B in annual revenue and US$1.89B in EBITDA by 2047, while conservation funding is embedded in every partnership through the 1.75% Torqua reserve and 1-5% B-Corp levy. Bottom-up GHG accounting across all 66 SPVs and the Mentawai Conservation Foundation adds US$464M (Base) to US$852M (Article 6.2 ITMO Upside) in verified Carbon NPV - flipping green-premium industrial assets like HVO/SAF biofuels and regenerative agriculture comfortably above the 8% WACC hurdle.

Portfolio

Diversified Across Sectors and Risk Profiles

The portfolio spans geothermal energy, HVDC transmission, desalination, mineral processing, dual-hub data centres, low-carbon modular construction, HVO/SAF biofuels, regenerative agriculture, luxury hospitality, and green financial services. Geothermal baseload cuts internal power costs by 65%-75% (to US$0.07-$0.09/kWh), while low-carbon construction locks away 500-750 kg CO2/m3 to certify island real estate as Net-Zero Embodied Carbon.

Structure

Ring-Fenced SPVs

Each major operation is held within one of 66 dedicated special purpose vehicles under 11 sector holding companies, providing clear governance, standardized 22-year financial and carbon valuation workbooks, and defined investor rights. SPV structures enable both direct investment into specific operations and portfolio-level participation.
