Abstract: Reports a policy to reduce America's emissions of `greenhouse gases' was conspicuously missing from the proposals announced by President Bill Clinton on October 19, 1993: a tax on fuel. `The Climate Change Action Plan' presented by Clinton and Vice President Al Gore contained a lot of hot air; Clinton's hope that voluntary co-operation with industry will produce a reduction in emissions; Partnerships to stimulate development of energy-efficient motors; Other ideas; Green lobbies.
