It was a shock to hear that Graeme has passed away. I had the honour of being the lawyer on his CO2 leadership team at Shell for a few years. I was always impressed by his knowledge about science and business, but also football and music, his wisdom, humour, agility and openness. In many aspects he was way ahead of his time. Thank you, Graeme, for your leadership. Rest in peace. My deepest sympathy to his whole family.
