Chart of the week | Green hair, green branches, green skin, green tariffs?

In this ‘Chart of the week’, we look at how prevalent green supply has become, unpick some of the drivers behind this, and look at the challenges now facing consumers, suppliers and policy makers confronted by a sea of green.
