By TARYN TORO in BERLIN AS THE world’s environmental ministers prepare for a meeting in London at the end of this month, West Germany has taken a dramatic lead in the battle to save the ozone layer by announcing that it is to ban the domestic use and production of ozone-destroying chlorofluorocarbons by 1995. The ban, announced last week, will be enacted in gradual steps starting next year. In 1991, use of CFCs as aerosol propellants and in the manufacture of foam products – packaging material, for example – will be prohibited. By 1995, the Germans will ban CFCs from all solvents, refrigerators and air conditioners, and also in the manufacture of foam insulation. In addition, in 1992, there will be a ban on the use of halogenated hydrocarbons, or halons, in hand-held fire extinguishers and on the use of carbon tetrachloride and methyl chloroform as solvents. Halons will be banned in other firefighting equipment in 1996. The use of another compound, chloro fluoromethane (CFC-22), as a substitute refrigerant and blowing agent (for producing foam) will be permitted until 2000. But its use as a component of building foam will be banned from 1993. Industry has three months to comply with these standards from the day the decree comes into force. On the day the cabinet’s decision was announced, Germany’s two CFC producers, Hoechst and Kali-Chemie, presented the minister of environment, Klaus Topfer, with a written statement in which they committed themselves to ceasing production by 1995. The German Chemical Association issued a similar statement. According to the West German government’s announcement, industry must begin reclaiming and recycling CFCs in existing appliances no later than six months after the decree becomes law. Topfer said the cabinet was merely complying with public opinion: ‘Including CFC-22 in the ban sends a worldwide signal that, for the German government, the substitution of partially halogenated CFCs is not a long-term solution to the ozone problem.’ He also said Germany would support an international commitment to strengthen the measures called for in the Montreal Protocol,
