Your Company's Climate Report Says You're Fine. It Shouldn't.
Planet Simple Trap - Scenario Analysis vs Sensitivity Analysis
A retailer plans to grow by opening one new store a month for the next five years. To check whether the plan is sound, leadership stress-tests it against changing conditions: slower consumer spending, higher real estate costs, faster wage growth. The plan still works in each case, with margins compressed but the model intact. The plan is declared resilient.
Now consider a different exercise. The same team asks what futures the business might actually face over five years – not just shifts in cost or demand, but real changes in how people shop, where they live, what they value. They ask which parts of the growth plan would still apply, which would have to be rebuilt, and what kind of organization the company would have to become in each future.
Both exercises look like rigorous planning. Only one of them puts the plan itself in question.
That’s the difference between sensitivity analysis and scenario analysis. They look similar. They are not. And this distinction is at the heart of one of the most widespread Planet Simple traps in corporate sustainability today, one that most companies making the mistake don’t know they’re making.
What Scenario Analysis Is Actually For
Since the Task Force on Climate-related Financial Disclosures (TCFD) made climate scenario analysis a mainstream expectation for corporations, there has been a proliferation of published analyses. Many of them are well-intentioned. Many of them are, upon close inspection, sensitivity analyses.
The difference is structural. Scenario analysis asks: How might the world change, and how would our strategy need to evolve to succeed across those futures? It takes the future as genuinely open and asks what it would mean for the business model – not just for current financial performance – if conditions changed substantially.
Sensitivity analysis asks: How would our current strategy perform if conditions changed? The business model is fixed. The question is whether the existing strategy is durable against a particular challenge.
Most corporate climate analyses don’t challenge the business model. They take the current business strategy as given and quantify a financial impact from climate-related variables. The output is usually something like: our EBITDA could be affected by 1.8% under a 2°C scenario. The company declares itself resilient. Nothing about the business model has been examined.
Why the Distinction Matters
A sensitivity analysis capped at 2 percent of revenue will not tell you that your core market might not exist under a 4°C world. It will not reveal that your logistics model depends on infrastructure that becomes unreliable under high-emissions pathways. It will not force you to confront whether your strategy is viable across futures that look fundamentally different from today.
These are questions that genuine scenario analysis surfaces. They’re uncomfortable because they require challenging assumptions about the business, not just running projections against the existing one. That discomfort is precisely why the sensitivity analysis masquerades as the scenario analysis.
I’ve seen companies disclose that they are “resilient to climate change” because their modeled financial effects under a defined scenario were less than 2 percent of today’s revenue. That disclosure isn’t dishonest. It’s something more insidious: it’s technically defensible while being strategically meaningless.
What Genuine Scenario Analysis Looks Like
It starts by acknowledging that climate change is a form of systemic instability that affects the entire environment in which a business operates, rather than a specific, bounded risk to be stress-tested.
And critically, the output isn’t a number. The output is a set of strategic questions: Which elements of our current strategy are robust across these scenarios? Which are only viable in the scenarios most like today? What would need to change if the world moved toward the high-emissions pathway?
That’s what scenario analysis is for. Not to declare resilience. To earn the right to say you’ve examined it.
