The ASA have published some advice for marketers when dealing with ads which make environmental claims, I have copied it below but this is available on their website.
The 5th of June was World Environment Day, a UN initiative to raise awareness and encourage action to protect the environment. To coincide with this we’ve put together some guidance to help you make sure you make sustainable claims in your advertising.
Be 100% sure about your renewable energy claims
In applying the ad rules, the ASA considers that consumers are likely to generally understand that electricity generated from renewable sources will be distributed through the national grid. Energy providers who can prove that all the energy they produce is from renewable sources can therefore claim that they offer ‘100% renewable electricity’ or similar, since the overall environmental impact of changing from a provider not offering 100% renewable tariffs will be the same. However, they should still make clear that the energy will be supplied to the national grid and not imply that it will be supplied directly to homes.
Hold appropriate substantiation
The ASA has always expected advertisers making claims about the environmental impact of products and services to hold substantial evidence and the CAP Code makes clear that absolute claims (like ‘green’ or ‘environmentally friendly’) should be supported by a high level of substantiation. Comparative claims like ‘greener’ or ‘friendlier’ will require verifiable evidence that proves an environmental benefit over comparable products (Rule 11.3).
Take care with recycling claims
If a marketer wishes to claim that their product is recyclable, they must hold appropriate evidence, as in this ruling on Carpet Recycling UK Ltd. Similarly, marketers should make clear if only part of a product is recyclable.
If a marketer claims that their product is 100% recycled then it really must be 100%, not merely close, as this ruling on Colourful Coffins Ltd demonstrates.
On that note, read all the details in our advice on recycling claims.
Keep emissions claims in check
Claims about the environmental impact of electric or hybrid vehicles and their emissions should be suitably qualified, for example claims that an electric car produces no emissions should be clarified to make clear it is while driving only. Official fuel consumption claims, as for any vehicle, need to be qualified to make clear that they’re primarily for comparison purposes and are not intended to reflect results in real-life driving.
So, environmental claims can be acceptable but must be supported by first-rate evidence. As always, you can get expert, free and confidential advice on your non-broadcast campaigns by contacting the CAP Copy Advice team.
