Scientists raise doubts over Leon’s ‘carbon-neutral’ burgers

Experts question credibility of environmental claims made by UK restaurant chain

The environmental credentials of Leon's carbon-neutral" burgers have been questioned after it emerged the fast-food chain was using controversial carbon offsets to make the claim.

In January, Leon announced it would become the first restaurant chain in the UK to serve carbon-neutral burgers and fries at more than 60 locations by reducing and offsetting the emissions they produce.
