Summary
The objective of this study is to describe future visions and scenarios for achieving the goals of Low Carbon Society (LCS) and Sustainable Development (SD) and explain modeling tools to assess future scenarios of LCS and SD toward 2050. There is no silver bullet to achieve LCSs. A portfolio of options and international cooperation is necessary to realize global LCS. Aligning SD and climate change actions can reduce the burden and facilitate the transition to stabilization. In the near-term, the LCS actions will deliver multiple dividends if aligned with the Millennium Development Goals (MDGs). In the long-run, climate stabilization will require significant technological change. Mainstreaming the development, transfer and deployment of low carbon technologies in national SD policies and actions will be the key to a cost-effective transition to LCS.
