Abstract: | Increasing atmospheric concentrations of greenhouse gases are widely expected to cause global warming and other climatic changes.
It is important to establish priorities for reducing greenhouse-gas emissions, so that resources can be allocated efficiently
and effectively. This is a global problem, and it is possible, on a global scale, to identify those activities whose emissions
have the greatest potential for enhancing the greenhouse effect. However, perspectives from smaller scales must be appreciated,
because it is on scales down to the local level that response measures will be implemented. This paper analyzes the relative
importance of emissions from the many individual sources, on scales ranging from global to national to subnational. Individual
country perspectives and proposed policy measures and those of subnational political entities exhibit some commonalities but
differ among themselves and from a global-scale perspective in detail. |
