Climate and Valuation: Alternatives
Private markets test the same climate logic at asset level, where there is no liquid market price and the analyst must build the cash flows. The exam focuses on real assets, private equity and natural capital.
Infrastructure
Value thermal and renewable generation through contracted versus merchant revenue, regulated asset base mechanics, concession life against technical asset life, and cost of capital. Transition risk in merchant thermal assets is a volume-and-price story once a carbon cost enters the dispatch curve and a phase-out date caps the residual life. Greenfield renewables carry construction and grid-connection risk; blended finance with concessional first-loss capital is the standard way to improve risk-adjusted returns in emerging markets.
Real estate
CRREM decarbonisation pathways give each building a stranding year - the point at which its energy intensity breaches the sector pathway. That year drives retrofit capex, exit cap rate and financing availability. Minimum energy efficiency standards, EPC ratings, insurance withdrawal in flood and wildfire zones, and physical hazard modelling sit alongside the carbon analysis. Brown discounts widen as regulation approaches.
Natural capital and private equity
Forestry and agriculture valuation stacks timber income with carbon credit revenue, but credits are finite in duration, subject to buffer pool deductions for permanence risk, and priced on verification standards such as Verra or Gold Standard. Climate tech venture and growth investing relies on cost-curve learning rates and first-of-a-kind risk; the exit route matters more than the terminal multiple.
Worked example
A 40m office asset generates 2.0m net operating income, a 5.0% cap rate. Its CRREM stranding year is 2029. A 4m retrofit cuts energy intensity by 40% and pushes stranding to 2040, but income dips to 1.8m during works. Without retrofit, a brown discount widens the exit cap rate to 5.5%, giving 36.4m. With retrofit, 2.05m at 5.0% gives 41.0m, less 4m capex, so 37.0m plus a longer hold option. The decision turns on the cap rate spread, not the energy saving, so model the spread explicitly.
Traps
Applying listed REIT liquidity and multiples to direct assets; assuming insurance remains available in a high-hazard zone; capitalising carbon credit income in perpetuity; ignoring concession expiry when valuing infrastructure; using a corporate WACC for a project-financed asset.
