This week I was joined by Andrew Griffiths Director of Policy and Partnerships from Planet Mark for the Sustain Talks chat.   Andrew shares his views on sustainability and net zero and setting targets and how Planet Mark encourages businesses to reduce their carbon footprint.    He also shares his thought on COP27 having attended giving a very candid view on what he thought of the event and the outcomes.    We also discussed accreditations, what they mean and why they matter and what the future looks like and how he sees it.
