Governmental policy options in response to increasing concern over an emerging greenhouse warming are reviewed. These will reflect differing levels of pofitical concem as understanding on the future size and impacts of the greenhouse effect evolves. High levels of concem will place emphasis on the option of limiting C02 emissions by restricting fossil fuel use. This option requires emphasis on energy efficiency and changes in energy supply, with increased use of natural gas, nuclear power or renewable energy sources. The progressive industrialization of the LDCs with the consequent growth in energy demand, may put additional pressure on developed countries to take action on this policy option.
