"Measures to reduce emissions can, in the main, be achieved at starkly low costs especially when compared with the costs of inaction," said Achim Steiner, executive director of the United Nations Environment Program, which, together with the World Meteorological Organization, established the Intergovernmental Panel on Climate Change in 1988.
The final report addresses possible ways of reducing emissions from principal sectors:
The energy supply sector: Governments would need to promote a range of options. Carbon-intensive fossil fuels could be substituted for by natural gas or mature renewable energy technologies like large hydroelectric dams and burning biomass (which does not add new carbon dioxide to the atmosphere like the burning of a long-buried fossil fuel does). Other renewable sources in development include solar-assisted air conditioning, wave power and nanotechnology solar cells. The report also included nuclear power, which - while saddled with issues - does not generate greenhouse gases.
Buildings: Greater use can be made of existing technologies like passive solar design; high-efficiency lighting and appliances; high-efficiency ventilation and cooling systems; solar water heaters; insulation materials and techniques; high-reflectivity building materials; and multiple glazing. Government policies like continuously updated appliance standards and building energy codes could further contribute.
Transport: Efficiencies could come from new and emerging technologies like directed-injection turbocharged diesels; improved batteries for road vehicles; regenerative braking and higher efficiency propulsion systems for trains; and blended wing bodies and unducted turbofan propulsion systems for airplanes. Biofuels also have the potential to replace a substantial part of the petroleum now used by transport.
Public transport and nonmotorized transport can reduce emissions.'
