A retailer plans to grow by opening a new store every month for the next 5 years. To check the plan, leadership stress-tests it against changing conditions: slower consumer spending, higher real estate costs, faster wage growth. Margins get squeezed in every case, but the model holds. The plan is declared resilient.
Now take a different exercise. The same team asks what futures the business might actually face over those 5 years, including real changes in how people shop and where they live. They ask which parts of the growth plan would still apply, which would have to be rebuilt, and what kind of company they’d need 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’re easy to confuse, and confusing them is one of the most widespread Planet Simple traps in corporate sustainability. Most of the companies making the mistake don’t know they’re making it.
What scenario analysis is for
Since the Task Force on Climate-related Financial Disclosures (TCFD) made climate scenario analysis a mainstream expectation, published analyses have multiplied. Look closely and a lot of them are sensitivity analyses.
The difference is structural. Scenario analysis asks how the world might change, and how your strategy would need to evolve to succeed across those futures. It treats the future as open and asks what substantial change would mean for the business model itself.
Sensitivity analysis asks how your current strategy would perform if conditions shifted. The business model stays fixed. The only question is whether the existing strategy can take a particular hit.
Most corporate climate analyses take the current strategy as given and put a financial number on climate-related variables. The output usually reads something like “our EBITDA could be affected by 1.8% under a 2°C scenario.” The company declares itself resilient. The business model never comes up.
Why the distinction matters
A sensitivity analysis capped at 2 percent of revenue won’t tell you that your core market might disappear in a 4°C world. And it won’t reveal that your logistics model depends on infrastructure that gets unreliable under high-emissions pathways.
Those are the questions scenario analysis surfaces. They’re uncomfortable because they put the business’s own assumptions on the table. I think that discomfort is a big part of why sensitivity analyses keep getting passed off as scenario analyses.
I’ve seen companies disclose that they’re “resilient to climate change” because their modeled financial effects under one defined scenario came in under 2 percent of today’s revenue. That’s technically defensible and strategically meaningless. In some ways it’s worse than a false claim, because it’s so hard to challenge.
What real scenario analysis looks like
It starts from the premise that climate change is systemic instability, affecting the entire environment a business operates in. The scenarios describe whole futures, including the disruptive pathways at the edges of the range.
And the output is a set of strategic questions. Which parts of our current strategy hold up across these scenarios? Which only work in the scenarios that look most like today? What would have to change if the world moved toward the high-emissions pathway?
That’s what scenario analysis is for: earning the right to say you’ve actually examined your resilience.
