This petition was rejected

The Government e-Petitions Team gave the following reason:

It isn't clear whether you want the UK Government to ban just the sale of pure palm oil or products which contain unsustainably farmed palm oil. The Government also only has the responsibility to ban sales in the UK.

You might want to start a petition calling on the Government to ban the sale of products in the UK which use unsustainably sourced palm oil. You might want to offer a definition of sustainable palm oil.
