Britain’s emissions of greenhouse gases, blamed by many scientists for contributing to global warming, have fallen by 14 percent since 1990, according to the latest government report.
British lakes and rivers are also on the road to recovery from acid rain poisoning, following successful curbs to air pollution from cars and heavy industry.
The report by the National Atmospheric Emissions Inventory (NAEI) attributed the drop in greenhouse gas emissions to several factors including: the introduction of catalytic converters on cars, a move toward low sulphur and lead-free petrol and a switch to gas from coal and oil in power generation.
Environment Minister Michael Meacher said the downward trend was welcome, but warned of complacency.
"Even though these figures are encouraging, we must not be complacent. There are still significant problems where we need to do more, for example, to further reduce greenhouse gases and harmful pollutants (污染

Owing to the insufficient gas supply in the United States, the gas price has dramatically risen. The new gas price reality and the policy decisions it may trigger will undoubtedly lead to critical financial implications for some individuals or companies, but the situation can hardly be termed a "national crisis" or even a "shortage". What is true is that buyers--particularly those in the chemical industry and in independent power generation -will not be able to acquire the quantity of gas they wish at the prices they wish to pay, or even at prices that will allow them to remain competitive in their markets, particularly during peak demand seasons.
Over the next year or two, the result will be higher, and more volatile prices, to be sure, but there are market-driven adjustment mechanisms even in the short term, e.g., more electric power from coal and oil, reduced production of domestic chemicals, and a commensurate substitution of
