Learn more about our organisational commitments and why we're optimistic about what Which? can achieve

Which? is committed to championing sustainability for consumers and bringing sustainability to the core of our values, mission and purpose. We’ve always helped you to confidently buy better products, now we’re eager to help you to make more sustainable choices that can reduce harm to the environment – including when not to make a purchase. We are also putting consumers at the top of the agenda when we work with policymakers and businesses to deliver sustainable solutions.

Working for consumers

Our Eco Buy badge now highlights the most sustainable products that have the smallest impact on the environment, while our investigations team is working on introducing green ratings into our energy provider and supermarket recommendations. Our product testing team is working with other European consumer testing organisations to introduce full lifecycle analysis into our reviews. In addition to this, we’ve focused our traditional reliability surveys firmly on brand longevity and repairability, and stopped making Best Buy recommendations for lithium-ion cordless products that don’t have replaceable batteries.

Which? has worked with Consumers International on projects that include the United Nations environment programme on plastics. We’ve given our support to Climate Assembly UK Climate Assembly UKA randomly selected and representative group of over 100 UK citizens, aged 16–79, tasked with working out how the country should reach the 2050 net-zero target and taken account of its findings and government plans in our policy work. We continue to provide feedback to government consultations on product eco design, energy labelling, electric vehicles and misleading green claims. 

We want to make sustainability simple for consumers. All of our advice on how to live and buy better for you and the planet can be found in one place on our website.

Working on ourselves

Following an assessment to understand and benchmark the waste output and energy use of our offices, we are making changes to our procurement practices and we’re set to switch to a greener energy supplier. These are the first steps towards building science-based targets in the year ahead with the ambition of making Which? a net zero Net ZeroA target of completely negating the amount of greenhouse gases produced by human activity, to be achieved by reducing emissions and implementing methods of absorbing CO2 from the atmosphere organisation in the future. We’ve also launched a full review of our print operations – from the paper we use, to the packing and shipping process. 

We acknowledge that our staff have a key role to play in reducing their carbon footprint, Carbon footprintThe amount of carbon dioxide (or the equivalent in other greenhouse gases) released into the atmosphere as a result of the activities of an individual or organisation so we’re looking at ways to support them to make changes – this isn’t a difficult task as many staff members are already green ambassadors. A network of Sustainability Champions has been set up and will hold Which? to account in all environmental issues. As an organisation we’re motivated and eager to embrace further change.

Which? Investigates podcast

The Which? Investigates podcast filters fact from fiction, and our first series shines a light on sustainability. From plant-based food to plastic-free products and electric cars, Electric CarsA zero-emission car that is powered entirely by a battery-driven electric motor. science journalist Greg Foot puts claims of sustainability under the spotlight to find out what genuinely reduces our environmental footprint.

Greg explains: 'I’ve always wanted to dig deeper into sustainability, to find out what genuinely reduces our carbon footprint and what is actually just marketing “greenwashing”, GreenwashingThe process of conveying a false impression or providing misleading information about how a company's products or services are more environmentally sound. and this podcast is going to do just that.'
