Did you know that over half a trillion dollars is spent on subsidising fossil fuels every year? A new report by the Overseas Development Institute shows how the rules of the game are biased in favour of dirty energy. Here's a game to help you find out more. To start, pick a number. Can I start with two? OK, two. Did you know that for every six dollars spent on fossil fuel subsidies in 2011? Just one dollar went to support clean, green, renewable energy. Wow, can't believe that. Can I go for number one next? One. Yeah. If we stop fossil fuel subsidies to consumers by 2020, we could cut greenhouse gases by 360 million tonnes. That's the equivalent to the annual emissions of France. Pick again. I'll have number six this time. Six. Social costs. This is a surprising one. Some governments spend more on fossil fuel subsidies than on basic services. Then as wailer, Pakistan and Indonesia, for example, spent at least twice as much on these subsidies than on public health. Right, pick another number. And I'll go for number three. Three. Carbon price. This one's important. A high price on carbon could deter the dirtiest forms of production. Unfortunately, today's carbon price is low, falling and rarely applied. So those are some of the facts. But how can we change the game? Vossal fuel subsidies need urgent attention. The G20 countries can take the lead if they phase out these subsidies by 2020 and support other countries to follow suit by 2025.
