Episode 2: 6 Types of Greenwashing Every Green-Tech Startup Should Avoid

Logo of Adopter - the marketing agency for deep tech and climate adaptation.

Katherine Keddie and Matt Jaworski, co-founders of Adopter, discuss greenwashing on Episode 2 of Scaling Green Tech, a podcast by Adopter

The episode works through six types of greenwashing identified by Planet Tracker - green labeling, green lighting, green shifting, green rinsing, green crowding, and green hushing - using examples from oil and gas, banking, and consumer goods to illustrate each. Keddie and Jaworski argue that greenwashing is not always deliberate: early-stage companies can drift into it through overclaiming, poorly scaled impact accounting, or decisions made before rigorous sustainability measurement was in place. The episode makes the case that transparent, evidence-backed sustainability claims are a commercial necessity for scaling companies - not just a reputational one.

This episode is relevant for founders, communications leads, and investors at green tech and climate tech companies navigating sustainability claims, ESG reporting, investor due diligence, and evolving regulations around environmental marketing.

Key Takeaways

  • Greenwashing does not have to be intentional. Companies can drift into it through early-stage overclaiming, impact accounting that doesn't scale, or decisions made before rigorous sustainability measurement was in place.
  • Planet Tracker identifies six types of greenwashing: green labeling (unsubstantiated claims), green lighting (spotlighting one initiative while the core business causes harm), green shifting (blaming consumers), green rinsing (quietly revising missed sustainability targets), green crowding (joining initiatives without taking action), and green hushing (deliberately under-reporting genuine progress).
  • Green hushing is the least visible but arguably the most damaging for the industry. When companies underreport real progress out of fear of backlash, it slows the sharing of ideas and makes collective targets harder to reach.
  • For investors, greenwashing is a direct risk signal. If a company's sustainability claims rely on a regulatory loophole, closing that loophole removes their competitive advantage entirely.
  • Build your sustainability story alongside your commercial case, not as a separate track. Programmes like Carbon13 require both from day one - an investor narrative and a carbon story, with ventures expected to demonstrate the potential to remove 10 million tonnes of CO2 per year per venture.
  • Exaggerating sustainability claims raises the question of what else is being exaggerated. Transparent impact accounting is both a trust signal and a commercial asset.
  • A specific, measurable sustainability story is essential for raising investment, acquiring customers, and keeping pace with tightening regulation - not a nice-to-have.

FAQs

  1. What is greenwashing? 

Greenwashing is when a company misrepresents its environmental credentials - either by making false or exaggerated claims, by emphasising a minor green initiative while the core business causes harm, or by staying silent about genuine progress to avoid scrutiny. It covers a wider range of behaviours than most people initially assume, and it does not have to be deliberate to cause reputational or regulatory damage.

  1. What are the six types of greenwashing? 

Planet Tracker identifies six types. Green labeling is making sustainability claims without evidence - for example, describing a product as biodegradable without proof. Green lighting is spotlighting a small positive initiative while the majority of the business causes environmental harm. Green shifting is deflecting responsibility onto consumers rather than addressing the company's own footprint. Green rinsing is announcing ambitious sustainability targets, missing them, and quietly replacing them with new ones. Green crowding is joining a high-profile sustainability initiative for the PR benefit without taking meaningful action. Green hushing is the reverse - deliberately under-reporting genuine progress out of fear of backlash.

  1. Why is green hushing a problem? 

Green hushing slows the sharing of real progress across the industry. When companies stay quiet about what is working - whether from fear of criticism or political backlash - it becomes harder for others to learn from them and for the sector to move faster. Waiting until your claims are fully verified is reasonable. Staying silent because you're worried someone will find fault is a different problem, and one that holds the whole industry back.

  1. Why does greenwashing matter to investors? 

Greenwashing is a risk signal in due diligence, not just a reputational one. If a company's sustainability claims rest on a current regulatory loophole, that advantage disappears the moment the rules tighten. Investors focused on green technology are increasingly asking detailed questions about impact accounting from the outset - and companies that can't answer them clearly are harder to back with confidence.

  1. How do you build a credible sustainability story from the start? 

Start with claims you can fully evidence. Be specific and measurable rather than broad and aspirational. Build your sustainability narrative alongside your commercial case - not as a separate track added later. If your impact accounting is still being validated, say so. That's different from greenwashing. The companies that avoid greenwashing as they scale are usually the ones that set up rigorous impact measurement early, before it becomes a problem to unpick.

  1. What is the difference between greenwashing and honest uncertainty?

A company that is transparent about the limits of what it can currently measure is not greenwashing. The distinction is transparency. Greenwashing - deliberate or not - involves presenting claims with more certainty or significance than the evidence supports. Saying clearly what you know, what you're working to verify, and what you don't yet know is the opposite of that - and it tends to build more credibility than overclaiming does.
