IKEA, the world's biggest furniture retailer, pledged on Thursday to spend 1 billion euros ($1.13 billion) on renewable energy and ways to help poor nations cope with climate change, in a new sign of companies upstaging governments on the issue, Reuters reported. The investments will be "win, win, win. It's good for customers, good for the climate and good for IKEA too," Chief Executive Peter Agnefjall told the wire service in an interview. He added that the plan fits with IKEA's goal of having a "positive impact on people and the planet." Senior officials from about 200 nations are meeting in the German city of Bonn this week to prepare for a summit in Paris in late 2015 at which governments aim to agree a deal to slow global warming.
