As environment experts meet at a UN summit on climate change in Durban to come up with the elusive 'binding agreement' on reducing carbon emissions, Counting the Cost looks at the real costs of climate change: How much money is being spent, what is not being spent and what is being spent smartly? And do spending habits make a difference while the search for a Kyoto Protocol replacement goes on?

Carbon trading is supposed to cap the amount of emissions made by companies, but could it be a huge waste of money? How can low-lying small islands protect themselves from rising sea levels? 

And we look at alternatives - examples from Pakistan and Japan in how climate change is challenged in small but effective ways.
