Alan cc list and Emily Shucks. I agree with you about the SRM form of "geo" not being mitigation.
But I was hoping that this list might agree that the mitigation term "reducing" could/should be interpreted broadly enough to include "removing". The reason to not do so is what?

They are jargon, but the community accepts these definitions, rather than a broader dictionary definition. Mitigation means reducing emissions that cause global warming.

Neither address the source of the problem, but they mitigate one of the problems. It could be called Symptom mitigation. CDR is also mitigation - reducing the pollution directly once emitted. Reducing emissions (what NGOs call mitigation) is mitigating the cause of the pollution. Mitigating climate impacts, indirect impacts and transboundary impacts on fauna and flora are a legal duty for any country with legislation like NEPA in the USA and the EIA directive in the EU. Analogous legislation exists elsewhere too. Should we be litigating any company with big projects covered by theses and countries not complying? Any lawyers on the list? Best wishes, Emily.

It is nonrival: one person’s consumption of the good does not inhibit another person’s consumption. It is also nonexcludable: once it is available to some, others cannot be prevented from consuming it. Gardiner argues that we already know that everyone cannot benefit from solar geoengineering. This seems to be an empirical claim that is possibly true but not well-supported by quantitative analysis. It is often said that there will be winners and losers but that is a claim that has not been established. In most analyses based on commonly-used metrics of "cost", everyone benefits by some level of solar geoengineering [cf. RIcke et al, attached]. Gardiner also imagines scenarios of coercion which, while possible are merely speculation. It may be premature to assert that we solar geoengineering is a public good, but it also seems premature to assert that it is not.

This paper argues that the paradigm example of geoengineering—stratospheric sulfate injection (hereafter ‘SSI’)—does not fit the canonical technical definition of a global public good, and that more relaxed versions are unhelpful. More importantly, it claims that, regardless of the technicalities, the public good framing is seriously misleading, in part because it arbitrarily marginalizes ethical concerns. Both points suggest that more clarity is needed about the aims of geoengineering policy—and especially governance—and that this requires special attention to ethics. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
