â€œSolar-powered sails the size of a jumbo jet’s wings will be fitted to cargo ships, after a Sydney renewable energy company signed a deal with China’s biggest shipping line. The Chatswood-based Solar Sailor group has designed the sails, which can be retro-fitted to existing tankers. The aluminium sails, 30 metres long and covered with photovoltaic panels, harness the wind to cut fuel costs by between 20 and 40 per cent, and use the sun to meet five per cent of a ship’s energy needs. China’s COSCO bulk carrier will fit the wings to a tanker ship and a bulker ship under a memorandum of understanding with the Australian company, which demonstrates the technology on a Sydney Harbour cruise boat. â€˜It’s hard to predict a time line but at some point in the future, I can see all ships using solar sails – it’s inevitableâ€™, said the company’s chief executive, Dr Robert Dane. Once fitted, the sails can pay for themselves in fuel savings within four years, Dr Dane said. They don’t require special training to operate, with a computer linked in to a ship’s existing navigation system, and sensors automatically angling the sails to catch a breeze and help vessels along.â€

â€œThe British Government has agreed to include aviation and shipping in a law setting targets to cut greenhouse gases. An amendment to climate change legislation tabled by ministers will compel the independent Climate Change Committee to take emissions from planes and tankers into account when it calculates carbon budgets, after more than 50 Labor MPs demanded the legislation be changed.â€
