Sustainability has become a key consideration in healthcare procurement, with NHS organisations and healthcare providers increasingly focused on reducing their environmental impact while maintaining high standards of patient care.

As a result, sustainability claims in healthcare have become more common. Terms such as net zero, carbon footprint, recyclable packaging and circular economy now appear across product literature and company communications. However, these claims can vary significantly in how they are measured, verified and reported. Understanding the evidence behind environmental claims is therefore becoming just as important as the claims themselves.

Why transparency matters when assessing environmental claims

Not all sustainability claims offer the same level of transparency.

A healthcare product may be described as sustainable, recyclable or low carbon, but without supporting evidence it can be difficult to understand its true environmental impact. Healthcare organisations should look for measurable data, recognised methodologies and independent verification when evaluating sustainability claims.

Good to know

The Green Claims Code in six principles

Published by the Competition and Markets Authority (CMA) for claims made to consumers, it’s also a useful benchmark for claims made to healthcare buyers. It says environmental claims must:

  • 1Be truthful and accurate
  • 2Be clear and unambiguous
  • 3Not omit or hide important information
  • 4Only make fair and meaningful comparisons
  • 5Consider the full life cycle of the product
  • 6Be substantiated with evidence

Five questions to ask when reviewing environmental claims

Select a question to see what good evidence looks like.

1
Is the sustainability claim backed by data?

Credible claims point to measurable figures, such as kilograms of CO2e per unit or the percentage of recycled content, not general words like “eco-friendly” or “green”.

Look for: specific numbers, units, and the date the data was collected.

2
Has the product carbon footprint been independently verified?

A third party checking the calculation against a recognised standard gives confidence that the figures are accurate and comparable with other products.

Look for: the name of the verifying body and the standard used, such as ISO 14067 or PAS 2050.

3
Does the assessment consider the entire product lifecycle?

Environmental impact happens at every stage: raw materials, manufacture, transport, use and disposal. A claim based on one stage alone can give a misleading picture.

Look for: a cradle-to-grave scope, or a clear statement of which stages are included.

4
Are environmental targets science-based?

Targets aligned with climate science show how planned reductions fit the pathway to limiting global warming, rather than being set arbitrarily.

Look for: validation by the Science Based Targets initiative (SBTi) and a clear baseline year.

5
Is sustainability progress reported transparently?

A target means little without regular public updates on progress, including where it has fallen short.

Look for: annual reporting, a consistent methodology year to year, and published data.

Scenario challenge

How would you assess this claim?

A supplier’s brochure says: “Our wipes are now carbon neutral, making them the sustainable choice for your department.”

Show how to assess it +
  • 1
    Is it backed by data? Ask what the claim is based on. “Carbon neutral” often means emissions were offset, not reduced, so ask for the product’s actual footprint in kg CO2e.
  • 2
    Has it been independently verified? Look for a named third party and a recognised standard, such as ISO 14067 for a product footprint.
  • 3
    Does it cover the whole lifecycle? Check whether the claim covers materials, production, distribution, use and end of life, or only part of it.
What would a stronger claim look like? +

“This product has a cradle-to-grave carbon footprint of [X] kg CO2e per unit, calculated to ISO 14067 and independently verified by [named body].”

Common healthcare sustainability terms

Try to define each term first, then tap the card to check your answer.


Carbon footprint
Tap to reveal

A measure of greenhouse gas emissions associated with a product, service or organisation. Carbon footprints are typically reported as carbon dioxide equivalent (CO2e).


Product Carbon Footprint (PCF)
Tap to reveal

Measures the greenhouse gas emissions generated throughout a product’s lifecycle and helps organisations compare environmental impacts using a recognised methodology.


Net zero
Tap to reveal

Reducing emissions as far as possible and balancing any remaining emissions through recognised removal methods.


Circular economy
Tap to reveal

A system designed to keep products and materials in use for longer through reuse, repair, recycling and recovery.


Independent verification
Tap to reveal

An external review process that confirms environmental data and calculations have been assessed against recognised standards.


Cradle-to-grave assessment
Tap to reveal

A lifecycle approach that evaluates environmental impacts from raw material extraction through to product disposal.

In focus

The five stages of a product lifecycle

A cradle-to-grave assessment looks at every stage. Select a stage to see what it covers and what to ask.


1
Materials

Where raw materials come from and how components are processed.

Ask: Are suppliers and materials traceable?


2
Production

Energy, resources, emissions and waste during manufacture.

Ask: Is the site powered by renewable electricity?


3
Storage and distribution

How products are stored and moved, and by which transport modes.

Ask: Is air freight avoided where possible?


4
Use phase

Water, electricity and consumables needed each time the product is used.

Ask: What does each use require in practice?

5
End of life

Recycling, recovery, incineration or landfill once the product is finished with.

Ask: Can packaging be recycled in your local system?

Environmental considerations in infection prevention and control

Sustainability within infection prevention and control (IPC) presents unique challenges. Access to independently verified sustainability data, including Product Carbon Footprints and lifecycle assessments, allows healthcare organisations to better understand the environmental impact of the products they use without compromising infection prevention standards.

Reducing environmental impact matters. But in infection prevention, patient safety, clinical efficacy and regulatory compliance must always come first.

Ultrasound probe in a clinical setting

By balancing sustainability objectives with clinical requirements, healthcare providers can support both environmental goals and patient care outcomes.

How healthcare providers can make better purchasing decisions

As healthcare organisations work towards ambitious sustainability and net zero goals, understanding how to evaluate sustainability claims in healthcare products has never been more important.

The NHS net zero journey

Why supplier evidence matters more every year

2028–2032

80% cut in the emissions the NHS controls directly

2036–2039

80% cut in the emissions it can influence, including suppliers

2040

Reflect on your practice

Choose one product your team uses every day. Can you find a verified Product Carbon Footprint for it? If not, which of the five questions above would you put to the supplier first?

Check your understanding

3 questions

Choose an answer to see if you’re right. You can open as many as you like.

Question 1. What does a cradle-to-grave assessment cover?

AManufacturing only

Not quite. Manufacturing is one stage, but it leaves out materials, distribution, use and disposal.

BRaw materials through to disposal

Right answer. It covers every stage, from raw material extraction to end of life.

CUse and disposal only

Not quite. These stages matter, but the assessment also includes materials, production and distribution.

Question 2. Which is the strongest evidence behind a product carbon footprint?

AThe supplier’s own estimate

Not quite. Self-reported figures are a start, but without verification they’re hard to rely on or compare.

BA footprint calculated to ISO 14067 and independently verified

Right answer. An independent check against a recognised standard gives the most confidence.

CA green logo on the packaging

Not quite. Logos and colours aren’t evidence. The Green Claims Code expects claims to be substantiated.

Question 3. In IPC, when should sustainability take priority over clinical efficacy?

AWhen the cost savings are large

Not quite. Cost matters, but it never outweighs patient safety or efficacy.

BWhen the product is recyclable

Not quite. Recyclability is valuable, but it can’t compensate for a product that doesn’t perform clinically.

CNever: patient safety and efficacy come first

Right answer. Sustainability is weighed alongside clinical requirements, never above them.
