Holahan, R.; Kashwan, P. (2019): Disentangling the rhetoric of public goods from their externalities: The case of climate engineering. In: Global Transitions 1, S. 132–140. DOI: 10.1016/j.glt.2019.07.001.

"Public goods are defined by the technical conditions of nonexclusion and nonrivalry. Nonetheless, public goods are frequently viewed in environmental policy and scholarly debates as providing strictly positive benefits (or, in the case of public ‘bads’, providing strictly negative costs). We provide a theoretical understanding of heterogeneous externalities produced by public goods to challenge this assumption, by highlighting the ways in which a single public good can simultaneously produce positive benefits for some and negative externalities for others."

"As part of Stripe’s environmental program, we fully offset our greenhouse gas emissions by purchasing verified carbon offsets. Starting this year, we’re going a step further. In addition to our offset program, we are committing to pay, at any available price, for the direct removal of carbon dioxide from the atmosphere and its sequestration in secure, long-term storage. We’re announcing this commitment to solicit technology partners and to urge other companies to follow suit."

"Scientists in Sweden have engineered cyanobacteria that can photosynthesise the petrol substitute butanol out of carbon dioxide. The microorganisms could not only provide a way to make transportation fuels that don’t depend on fossil fuels, but they could also remove carbon dioxide already present in the atmosphere."

"This conference focuses on better understanding the processes and impacts associated with radiation management. This includes processes specific to individual methods, the projected climate response and its uncertainties, and the impacts, including those in the developing world, as well as the engineering aspects and the design of research to address risk."
