Global Monitoring Report 2008, the fifth in an annual series, is essential reading for those who wish to follow the global development agenda and debate in 2008. The year marks the midpoint toward the 2015 deadline for achieving the Millennium Development Goals (MDGs). It is also an important year to work toward a consensus on how the world is going to respond to the challenge of climate change, building on the foundation laid at the Bali climate change conference in December 2007. The report spans this agenda. It provides a comprehensive assessment of progress toward the MDGs and related policies and actions. It addresses the challenge of climate change and environmental sustainability and assesses its implications for development.
