This is the question Prince Charles pondered when we met with him yesterday to discuss sustainability together with representatives of the accounting bodies of the UK. I certainly hadn't been at a meeting table on a moving train before, and pitied the stewards pouring coffee!

Marking the launch of the Accounting for Sustainability Wales Forum – the meeting was scheduled in order to share objectives with the Prince, whilst he was travelling between Cardiff and Bristol on the Royal Train – promoting sustainability across the UK.
