Over the last two years, sustainability has risen up the boardroom agenda, with an increasing number of businesses setting targets to reduce their impact on the environment.

As co-founder of business-focused environmental campaign group A Plastic Planet, Sian Sutherland, puts it: “It’s gone from being the sustainability director who no one really wanted in the room, to the person who is absolutely front and centre.”

Perhaps most visible is the sector’s war on plastic. A move in the UK that was spurred by David Attenborough’s 2017 Blue Planet II BBC series, which – after showing how plastic pollution was devasting the world’s marine environment – ignited a major public debate.
