Seven of nine planetary boundaries are crossed. What is your progress measured against?
Most corporate targets still measure progress against their own baseline, not against fixed physical limits. That gap is now a financial, regulatory and reputational exposure.

Less impact is not the same as sustainable.
Efficiency gains lower unit costs, widen markets and are re-spent as further output, so total pressure on the Earth system can rise while intensity per unit falls. The dominant approaches improve or report relative performance; none tests whether a business is compatible with a fixed physical ceiling. We help you decide where to play, how to win and how to execute within planetary boundaries.

The APres Framework for Business within Planetary Boundaries.
APres, the Adaptive Planetary Resilience Exchange System, is a framework that reframes the logic of economic exchange to account for the planetary boundaries. It gives practitioners a set of methodologies and tools to strategise and create value while maintaining ecological balance. It includes a methodological canvas and an evaluation system that scores value propositions against eight dimensions mapped to the planetary boundaries.

Bridging Earth system science and business economics
Business and economic theory still overlook planetary thresholds. A growth forecast or a cost curve can be set with no reference to physical limits. The Think Tank's research puts them back into the decision.
