Chris Lenon draws on Rio Tinto experience in ideas on emissions trading and tax transparency

Chris Lenon was the global head of tax at Rio Tinto and chaired the Tax Committee of the Business and Industry Advisory Committee to the OECD. He chairs the Green Tax Group at Business Europe and has just launched a new website providing a rare business view on two of the more hotly debated issues in global taxation: green taxes and tax transparency. Lenon talks to Salman Shaheen about the need for tax directors to engage in such a crucial discussion.
