The document discusses transitioning to low-emission development. It summarizes that international climate change negotiations aim to establish a new global agreement by 2015 to reduce emissions starting in 2020. Many countries have already developed low-emission development strategies and climate action plans. Transitioning to low-emission development will require significant emission reductions through policies like carbon pricing, clean technology development, reducing deforestation, and changing consumption behaviors. Governments are also promoting energy savings through initiatives like efficiency standards, consumer information programs, and incentives. Rapid urbanization presents both challenges and opportunities for reducing emissions through more sustainable city development.
