The carbon cost of breakfast at COP26
Can a vegan croissant really be worse for the environment than a bacon roll? Tim Harford questions how the carbon cost of food is calculated.
A French minister told people to eat fewer croissants at this year鈥檚 COP26 summit, after the menu said the carbon cost of the pastry was higher than that of a bacon roll, even if it was made without butter. Tim Harford investigates whether this claim could be true, and how the effect of food on climate change can be measured.
