Birganj, Nepal
Eleven years ago, when 74 tons of a contraband gas used in refrigeration and air-conditioning were seized by customs at the Indo-Nepal border here, it was hailed internationally as a major victory in the campaign against smuggling of chemicals that destroy the Earth's protective ozone layer.
But no one thought of what to do with the nearly 900 cylinders of gas, and they have remained in a dusty and stuffy warehouse in Birganj since 2001. Now, after years of negotiations, the last of the chemicals will be shipped to the United States for destruction, and the entire process will be funded by carbon credits earned in removing a potent greenhouse gas.
Called CFC-12, the gas is not just banned by the Montreal Protocol because it is harmful to the ozone layer, it is also 10,900 times more powerful than carbon dioxide as a greenhouse gas. Nepal is a signatory to the Montreal Protocol and, as a developing country, was allowed to use some of the CFC until the complete ban went into force in 2010.
But there was still eight tons of the chemicals left, and Nepal's Bureau of Standards and Metrology, the California-based EOS Climate and the United Nations Environment Programme (UNEP) have joined forces to use the international carbon trading market to pay for the destruction.
