This report is on the recent public debate on the Rio Earth Summit agenda, which took place at St Martin-in-the-Fields, London. The Secretary General of the UN has labelled the Rio+20 Conference as one of the most important conferences in the history of the United Nations. In not attending the Rio Earth Summit, the Prime Minister is sending out a powerful signal that the UK Government does not see sustainability as a priority. Public attention is understandably focused on the financial crisis, but we risk sleep walking into an even worse environmental crisis if world leaders cannot find a greener and cleaner way of developing our economies in future. It is down to us to find these solutions and to insist that our governments do so too. The Committee have produced a previous report on the Rio+20 agenda (HC 1026, session 2010-12, ISBN 9780215561954), and since then there has been a debate in the House of Commons on that report and the Government's response to it. The Committee intends to examine the outcomes of the Rio+20 Summit, and the action the UK will need to take, later in the year. That will provide an opportunity to review the way the Government approached the Summit and its role there. Key issues to be examined will be the extent to which the Government shows leadership at the Summit on the green economy agenda, and subsequently whether the Government revisits its 'Enabling the Transition strategy' to reflect the outcomes of the Summit.
