July 5, 2012. The low-carbon products and services sector, often referred to as green business, could contribute 20 billion pounds ($31.16 billion) to Britain's economy by 2015. But the CBI warned that if the government does not adopt the right policies the sector will not reach its full potential, putting 400 million pounds in net green sector exports at risk in 2014/15. The CBI wants the government to meet its fourth carbon budget, which sets goals for Britain's carbon-cutting programme, to ensure its current electricity market reform gives long-term investment signals. It also wants the government to reduce complexity in low-carbon regulation.
