The Greenwashing
Literacy Project

An independent educational initiative

Read the claim before it reads you.

Greenwashing literacy: the ability to recognise a misleading sustainability claim, reason about its evidence and omissions, and respond constructively.

The project exists to make that ability ordinary — at the supermarket shelf, in the seminar room, and in front of an annual report.

01 / Definition

What is greenwashing?

Greenwashing is misleading or overstated environmental communication. It can appear in advertising, packaging, institutional statements, annual reports, public relations, social media posts and campaign slogans.

Not every sustainability claim is false. The literacy task is to ask whether a claim is specific, evidenced, scoped and honest about its limits — and to notice when warmth is doing the work that evidence should do.

Vague product claim

“100% planet kind”

A warm phrase can sound responsible without saying which impact has improved, compared with what, or by how much.

Transition claim

“Powering today, building tomorrow”

A both-and statement can present expansion and transition as equally compatible without showing the pathway between them.

Energy-security claim

“Keeping the lights on for decades”

A security frame can turn long-term dependence into common sense while leaving the alternatives unexamined.

02 / Change

Why greenwashing has changed

Contemporary greenwashing is not only vague green packaging. Increasingly it works through climate-delay framings: accepting that climate change matters while making slow or inadequate action feel reasonable.

Lamb et al. (2020) identify four broad delay families. They help us notice how a message can appear realistic while quietly narrowing what counts as possible.

1

Redirect responsibility

Move attention away from institutions, systems or producers and towards individual choices alone.

Tell: “It's in your hands.”

2

Push non-transformative solutions

Promote improvements that sound decisive but do not alter the underlying high-emission model.

Tell: “Innovation will solve it.”

3

Emphasise the downsides

Make climate action feel too costly, disruptive or unfair, while giving less attention to the costs of delay.

Tell: “Change puts jobs at risk.”

4

Surrender

Suggest that meaningful change is impossible, too late, or unrealistic enough to excuse inaction.

Tell: “Nothing we do will matter.”

Six fictional statements. Which delay family is each one closest to?

03 / Tool

The four-question tool

The tool slows a claim down. It does not ask you to be suspicious of everything — it asks you to look at what a communication includes, what it leaves out, and what kind of future it makes feel normal.

01

What is claimed?

Identify the exact promise, benefit or impression. Separate measurable statements from mood words.

Look for
Scope, comparison, time frame, product versus company, absolute versus relative language.
Mini example
“Lower impact” only becomes readable when you know lower than what, and across which impact.
Warning sign
The central words feel positive but cannot be measured or tested.
02

What evidence is offered?

Check whether the communication gives enough evidence for the scale of the claim.

Look for
Named data, independent verification, methods, dates, baselines and accessible sources.
Mini example
A recycling claim is stronger when it states actual collection access and material recovery limits.
Warning sign
The evidence is a logo, a nature image or a broad value statement rather than substantiation.
03

What is omitted?

Ask what relevant information would change how the claim is understood.

Look for
Lifecycle impacts, offsets, exclusions, trade-offs, supply chains, absolute emissions and rebound effects.
Mini example
A “plastic-free” pack may still rely on high-impact materials or hard-to-recycle coatings.
Warning sign
The claim highlights one improvement while avoiding the main source of impact.
04

What future is normalised?

Notice the future the claim invites you to accept as sensible, inevitable or desirable.

Look for
Promises of later action, permanent demand, technological rescue, consumer responsibility and “realistic” delay.
Mini example
“By 2050” may be meaningful, or it may move responsibility into a future without near-term milestones.
Warning sign
The message makes continued high impact feel unavoidable while describing action as optional.
04 / Practice

The claim lab

Choose one of six fictional claims — from product packaging to an institutional pledge — then work through the four lenses. For each lens, pick the observation you find strongest and compare it with our reading. There is no perfect answer; the aim is to make the claim more inspectable.

05 / Response

From critique to response

The aim is not cynicism. A stronger literacy habit ends with a constructive move: rewrite the claim more transparently, or ask one public scrutiny question.

Original

“100% carbon neutral by 2050”

Eight words, no boundary, no baseline, no interim date.

Build a more transparent version

Rewritten

One scrutiny question to keep: What emissions, products, places and time periods are included in this claim — and what is left outside it?

06 / Glossary

Small glossary

Eight terms that do a lot of quiet work in sustainability claims. Knowing them makes most claims easier to question.

Scope 1, 2 and 3

Three boundaries for counting an organisation's emissions: direct emissions (1), purchased energy (2), and the value chain — suppliers, products in use, investments (3). Scope 3 is usually the largest and the most often excluded. Always ask which scopes a target covers.

Baseline

The reference year a reduction is measured against. “50% less” means little without one — a conveniently high baseline year can make modest progress look dramatic.

Offset

Paying for emission reductions or removals elsewhere — tree planting, renewable projects, capture — instead of reducing one's own emissions. Quality varies widely, and offsets inside a “neutral” claim often go unmentioned.

Lifecycle (LCA)

The full journey of a product: raw materials, manufacture, transport, use and disposal. A claim about one stage — say, packaging — may sit inside a lifecycle whose main impact lies elsewhere, such as the use phase.

Carbon neutral vs net zero

Often blurred. “Carbon neutral” frequently leans on offsets for a narrow boundary; “net zero” is meant to involve deep reductions first, with removals only for the residue. The words alone do not tell you which is happening.

Absolute vs intensity

An intensity measure (emissions per unit, per litre, per passenger) can fall while total emissions rise, if output grows. “Cleaner than ever per product” is compatible with a growing footprint.

Rebound effect

When an efficiency gain lowers cost and so increases consumption, eating part of the saving. Efficiency claims rarely mention it.

Climate delay

Discourse that accepts climate change is real while making inadequate action feel reasonable — by redirecting responsibility, pushing non-transformative fixes, stressing the downsides of action, or surrendering (Lamb et al., 2020).

07 / Educators

For educators

This resource can support a 60 to 90 minute activity for students, sustainability learners or programme teams. It works best as a guided reading exercise, not a test of personal virtue.

  1. Warm-up trust question

    Ask what makes a public sustainability claim feel trustworthy.

  2. Four-question tool

    Introduce claim, evidence, omission and future as a shared vocabulary.

  3. Real or regulator-validated case

    Use a careful public example where evidence has already been assessed.

  4. Fictional group cards

    The claim lab's six cards let groups practise on different claim types without accusing named organisations.

  5. Individual reflection

    Invite students to name one question they would ask next time.

Facilitators should avoid personal disclosure pressure and keep the focus on public communication, not personal guilt. A short session can build useful habits of scrutiny, but it should not be overclaimed as transformation.

08 / About

About the project

The Greenwashing Literacy Project is an independent educational initiative. Its mission is to make the critical reading of sustainability claims an ordinary public skill — the kind of habit people carry from the supermarket shelf to the ballot box.

The project's method is grounded in three bodies of research: critical media literacy, the study of climate-delay discourses, and transformative learning. It grew out of postgraduate education research at the University of Manchester, and everything on this site is free to use and adapt for non-commercial education.

10 / FAQ

FAQ

Is every sustainability claim greenwashing?

No. Many claims are useful, specific and well evidenced. Greenwashing literacy helps readers distinguish stronger claims from vague, selective or overstated ones.

Is this about blaming consumers?

No. The focus is public communication. Consumers and students should not be made responsible for solving every sustainability problem alone.

Can greenwashing be legal but still misleading?

Sometimes a claim may avoid a clear legal breach while still giving an unbalanced impression. This resource is educational and does not provide legal advice.

Why use fictional examples?

Fictional examples let learners practise the method without turning a workshop into a debate about a named organisation. Real cases can be added when they are carefully sourced or regulator-validated.

Can educators use the four-question tool?

Yes. Educators can adapt it for short classroom activities, media analysis, sustainability modules or staff development sessions.

How is this different from carbon literacy?

Carbon literacy focuses on understanding carbon impacts and actions. Greenwashing literacy focuses on reading sustainability claims, climate-delay framings and evidence in public communication.
