Leading UK fast-food chains have announced they are fully behind a new initiative to add methane suppressants to burgers in order to help the push towards 'net-zero' and reduce the greenhouse gases allegedly powering climate change.

A spokesperson for a leading fast-food chain told FNN:

Methane suppressants will be added to our burger's 'secret sauce' to ensure that there is a healthier atmosphere in our restaurants and in the surrounding streets.

The additive will made from a fully natural ingredient - Japanese seaweed - much of which will be sourced from the waters around the town of Okuma (in the Fukushima prefecture). Our tasting panel has confirmed that you can't taste the additive amongst all the other stuff people gobble down when they consume fast food.

The rumours that the additive can make you glow are nonsense. The only problem is that it is likely to reduce the air temperature in our restaurants so we may have to up the thermostat a bit to compensate.

EU spokesperson Ursula Von Richthofen told FNN:

We already add methane suppressants to the German national dish - currywurst - so this is just another example of Brexit Britain catching up with the EU. Vorsprung durch Teknik!

Swedish Lutheran Minister Greta Thunderberg is also getting on the bandwagon as one of her recent sermons berated the Swedes for not putting the same additive into Swedish meatballs, also a well-known source of flatulence..
