UN Urged by Own Staff to Look at Its Climate Footprint Reuters GENEVA - More than 1,000 United Nations employees have called for the global body to reduce its carbon footprint, including through curbs on their own diplomatic perks like business-class flights and travel handouts, a letter obtained by Reuters showed. The United Nations calls climate change the "defining issue of our time" and is hosting a New York summit on it next week. But reformers within say in the letter addressed to Secretary-General Antonio Guterres that it needs more radical change to get its own house in order. "Our commitments need to be more ambitious and at least as concrete as those of the UN Member States and non-party stakeholders attending the UN Climate Action Summit," said the letter, signed by more than 1,000 employees. It was organized by a group called Young UN, an internal network committed to ensuring the organization embodies the principles it stands for. .
