With the 1997 Kyoto climate change protocol expiring this year, the UN talks in Durban in December offered some hope that developed and developing countries can bind themselves to serious reductions in greenhouse gas emissions. The key word in that sentence was 'hope'. In fact, what the talks in Durban achieved was not a legally binding agreement or treaty but rather the principles on which a future agreement will be based. More talking is therefore needed to get an agreement by 2015 and in force by 2020.
