"The United States joined Saudi Arabia to derail a U.N. resolution that sought to improve the world's understanding of potential efforts to lace the sky with sunlight-reflecting aerosols or use carbon-catching fans.
The two countries were joined by Brazil in blocking the resolution at the U.N. Environment Assembly conference in Nairobi, Kenya, earlier this week. The measure asked the world's decisionmaking body on the environment to commission a report outlining research and planning related to carbon dioxide removal and solar radiation management. Those controversial efforts are still in the planning stage and are not operational.
Switzerland and nine other nations originally asked the U.N. Environment Programme for guidance on possible future governance options and analysis of the implications of geoengineering, but they agreed to substantially reduce the scope of their resolution in hopes that the United States, Saudi Arabia and Brazil would allow it to move forward. The final version, which failed to gain consensus Wednesday, would have asked UNEP only to provide a compilation by next year of current scientific research on geoengineering and U.N. bodies that have adopted resolutions regarding it."
