Label excessive packaging as false advertising and unjust use of resources.

Tighter legislation on the unnecessary use of plastic/cardboard packaging to make a product look larger (whether food or item) should be introduced as it is both a breach of marketing law, and a waste of unsustainable materials.

Petitions need to call on the UK Government or Parliament to take a specific action.

We're not sure exactly what you'd like the Government or Parliament to do. In particular, we're not sure what you mean by "labelling" excessive packaging as false advertising. Marketing and advertising are subject to codes of practice and Regulations. You can find out more here:

You could start a new petition explaining clearly what changes you would like the Government or Parliament to make.

There are already petitions about unsustainable packaging, for example this one about plastic food packaging, which you might like to sign. You're more likely to get action on an issue if you sign and share a single petition:

Ban the use of all non-recyclable and unsustainable food packaging
