Geoengineering

The term "geoengineering" encompasses various technologies aimed at mitigating the impacts of climate change by intervening in Earth's systems. These technologies involve reflecting sunlight back into space or removing carbon dioxide from the atmosphere. They offer a potential solution for climate change but come with far-reaching social, political, and environmental risks.

Here you will find current articles, publications, and thematic focuses on geoengineering.

Ban Solar Geoengineering

Background

Countless scientists and experts have warned that solar geoengineering would give emitters an excuse not to end their fossil-fuel addictions and cause far-reaching unintended consequences.

UN climate talks could undermine precaution on geoengineering called for by the biodiversity convention

Analysis

UNFCCC negotiations on Article 6 of the Paris Agreement risk legitimising dangerous Carbon Dioxide Removal (CDR) schemes and undermining precautionary work being undertaken in other UN fora.

UN-Science Summit: Countries Call for the Non-Use of Solar Geoengineering

Analysis

Recent developments at the 79th United Nations General Assembly and its accompanying Science Summit signal a growing political momentum toward restricting the development and potential deployment of solar geoengineering technologies.

Solar geoengineering at COP 28

Analysis

In the upcoming UNEA6 meeting in Nairobi, Kenya, to be held between February 26 and March 1st, Switzerland has proposed a resolution to advance global talks on controversial solar radiation manipulation techniques.

Surface Albedo Modification and Arctic Ice Management

Factsheet

Changing the surface albedo is a proposed solar geoengineering method that aims to reflect more sunlight back into space by increasing the Earth’s albedo—the reflectivity of the Earth’s surface.

Stratospheric Aerosol Injection (SAI)

Factsheet

Stratospheric aerosol injection is a proposed solar geoengineering method in which large quantities of tiny reflective particles are released into the stratosphere to cool the Earth by reflecting sunlight back into space.

Enhanced Photosynthesis

Factsheet

Enhanced photosynthesis techniques are theoretical geoengineering technologies based on the idea that plants and algae can be genetically modified to absorb and metabolize and therefore store more carbon dioxide.
