What the practice does
Our focus is to integrate ecological priorities with financial and development strategies, ensuring that every intervention creates tangible benefits for both people and nature.
Advisory work sets the direction the rest of the group follows: what a landscape needs, what balance of protection and production it can carry, and which of those decisions can be financed. The practice publishes its analysis openly — each working paper carries the reasoning, the data, and the assumptions behind it.
Programs
three program teams
Just Energy Transition Program
Power market reform, coal retirement, and transition finance: how Indonesia's electricity system can be sustainable, affordable, equitable, and low-carbon at the same time — and who pays for the shift.

Nature-Based and Ecosystem Services Program
Forests, peat, water and coasts as working infrastructure: nature-based recovery and resilience, ecosystem service development, and the measurement that makes both credible.
Program page →
Climate Crisis Risks, Carbon Management, and Net Zero Strategies
What the climate crisis costs, what carbon on the balance sheet is worth, and what a credible path to net zero requires: risk modeling, emission accounting, and costed roadmaps.
