Adapt or Collapse: Renewable Assets, Turning Avoided Emissions into Investment Value

Avoided emissions are increasingly used to show the climate value of renewable assets. Most estimates still treat them as a fixed number. They are not.

In this second episode of Adapt or Collapse, we look at what it takes for avoided emissions to support investment decisions rather than headline claims. The result depends on choices that are easy to overlook: the reference scenario, the grid an asset actually displaces, life‑cycle emissions, and how much the asset will produce over its lifetime. Small differences in these inputs can change the outcome materially.

The paper sets out three pillars for credible avoided emissions estimates (methodology, data and governance) and applies them to a real solar PV asset in northern France. Using Altitude’s renewable energy production analysis, it shows how the asset’s output is expected to change under three IPCC scenarios (SSP1‑2.6, SSP2‑4.5 and SSP5‑8.5) through 2050, with P50 and P90 estimates, and why a decarbonising grid gradually reduces the emissions avoided per MWh. It also brings in physical risk: for this asset, flood is the main exposure, which affects how durable its climate contribution will be.

The outcome is a dynamic view of avoided emissions, one that links climate impact to production reliability and physical resilience, and helps distinguish between assets that look similar at entry but evolve differently over the holding period.
