International climate change negotiations received an unexpected blow when the UN’s top climate change official, Yvo de Boer, announced he will step down from the post as of July 1. A Dutch national, de Boer was appointed as the Executive Secretary of The United Nations Framework Convention on Climate Change (UNFCCC) in September 2006. De Boer has been largely well regarded during his time in the position and is widely credited with raising the profile of climate negotiations and delivering a series of breakthroughs towards a deal. Though in recent months, the UNFCCC and their seminal reports produced by the Intergovernmental Panel on Climate Change (IPCC) have come under fire. While the science that underpins the IPCC studies remains strong, slight errors in the IPCC reports have raised the ire of climate change detractors. In a statement, de Boer announced he will take up a post as global adviser on climate and sustainability at consultancy giant KPMG, adding that it is the private sector that will ultimately deliver the deep cuts in carbon emissions that are required. “Copenhagen did not provide us with a clear agreement in legal terms, but the political commitment and sense of direction toward a low-emissions world are overwhelming. This calls for new partnerships with the business sector and I now have the chance to help make this happen,” said de Boer. His successor is expected to be named in the next few months.
