Lovelock was the first scientist to propose that chemical aerosols called CFCs might pose a threat to the ozone layer, but his faith in the restorative powers of Gaia led him to downplay the danger...
...Nearly 100 nations agreed on a ten-year plan to end worldwide production of chlorofluorocarbons (CFCs) and other chemicals that threaten the earth's protective ozone layer...

That pact called for a reduction by the end of the century in worldwide production of ozone-depleting CFCs and halons, man-made chemicals that allow ever increasing amounts of dangerous ultraviolet light to reach the earth's surface. But since Montreal, a consensus had been growing that mere limitation was not enough. All the participating nations agreed that both types of chemicals should be phased out almost entirely by century...
...conference also approved a landmark special fund that would provide $240 million over the next three years to help poorer countries switch to chemicals that are more expensive but less harmful than CFCs for use as refrigerants, solvents and propellants in spray cans. The fund, proposed long before the London meeting, had been a major sticking point until a few weeks ago, chiefly because the Bush Administration had declined to support it.
