IPCC treads carefully on geoengineering

As the Intergovernmental Panel on Climate Change (IPCC) wound up its expert meeting on geoengineering in Lima, Peru, which included all three IPCC Working Groups, it committed to remain “policy relevant but not policy prescriptive.” Despite getting off on the wrong foot (no transparency), with some of the wrong experts (scientists with financial interests), on some of the wrong topics (governance), the IPCC has now confirmed that it will not make recommendations to governments regarding research funding for the controversial technologies, governance models or the legality of experimentation.

At a press briefing following the close of the expert meeting, the IPCC stated that its focus will be “establishing the scientific foundations for an assessment of geoengineering.” This assessment would include risks, costs, benefits and social and economic impacts, intended and unintended consequences as well as uncertainties and gaps in knowledge and will be based solely on peer-reviewed literature. “Of course, a real assessment of geoengineering will need to be much broader than a scientific peer-review process,” said Silvia Ribeiro of ETC Group from Lima, though outside the meeting. “Civil society organizations have been clear that we do not want these dangerous technologies developed; they are a new threat from the very same countries that are responsible for the climate crisis in the first place!”
