The Little Green Data Book 2009

The 2009 edition of the little green
data book includes a focus section, four introductory pages
that focus on a specific issue related to development and
the environment. This year the focus is on urban areas and
the environment, exploring how cities and climate change are
affecting the way we live and how good public policies can
improve prospects for future generations. Urbanization and
economic growth move in tandem. As emerging market economies
develop, they increase their contribution to greenhouse gas
emissions. The emissions of developed and developing country
economies together increase the vulnerability of cities to
climate change. Cities are particularly vulnerable to
climate change impacts because they concentrate people,
infrastructure, and economic activity. But good public
policies can reduce greenhouse gas emissions and other
pollutants while minimizing the impacts from climate change.
