Code of conduct for


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.
