It is not difficult to become a believer in global warming. According to the U.S. National Climatic Data Center 2001 was the second warmest year on record and it was the 23rd consecutive year of above normal temperatures. Perhaps most troubling is the fact that the rate of temperature increase is accelerating. Add to this the data just released from insurer Munich Re stating that deaths from natural disasters were more than double in 2001 versus 2000 and insured losses were up more than 50%.UNEP estimates that the extra economic costs of disasters attributable to global warming are running at more than $300 billion annually.
Some 180 countries are proceeding toward an expected ratification of the Kyoto Protocol by the end of this year. Of the six gases it will control CO2 is by far the largest contributing nearly 90% of the global warming impact. The primary source of CO2 is the burning of fossil fuels. Therefore the focus on energy will continue to increase.
Throughout the world different methods are being used to encourage reduced energy use. Japan has enacted the Energy Conservation Law in 1999 mandating huge efficiency improvements by 2004 for nearly all air conditioning products. The U.S. has revised ASHRAE Standard 90.1 for buildings to raise the minimum COP level for centrifugal chillers from the current value of 5.2 to 6.1 effective in October 2001. DOE and Green Seal have revised their recommended efficiency levels to an even higher level of 6.27.
Some countries use laws. Others use codes and standards. An increasing number of countries are using environmental costing which increases the price of energy thereby increasing the financial attractiveness of high efficiency products. European countries have been using such
