Geoengineering is central to scenarios that limit global warming to 2 °C —
for example, by removing carbon dioxide from the atmosphere or increasing
the planet's albedo (see Nature 527, 436–438; 2015). However, the
environmental and social implications of such technology are holding back
research. Developing an international code of conduct could resolve this
conundrum by ensuring that geoengineering proposals are subject to societal
scrutiny and oversight.

The code would provide flexible governance for a wide range of projects,
along with general principles and procedures to guide responsible research
and to inform regulatory processes for technologies as they develop (see

As well as encouraging early cooperation and coordination of research,
equity and sustainable development in the spirit of the 2015 Paris climate
agreement, the code should promote precaution, risk assessment, public
participation and transparency.
