Climate talks in Poland this week have been characterised by a widely different agendas and a failure to reach agreement on the hard targets necessary to halt emissions and reverse global warming. This debate is taking place in the Polish city of Poznan against protests by thousands of young people from across Europe. Promoters of renewable energy, such as the designer of the Solar Taxi that toured the world earlier this year have used the opportunity to promote potential solutions to reducing carbon consumption. Developed countries have argued for a global target to halve emissions (from 1990 levels) by 2050, developing countries have argued that developed countries have to set aggressive targets for the next decade. The US, for example, has agreed to reduce emissions to 100 percent of 1990 levels by 2020, Australia has refused to announce a target, but flagged that 95 percent is realistic. Developing countries have emphasised the need to provide financial and technical support to implement post-carbon solutions.
