By 2025, more than 12 billion tonnes of plastic had been produced globally – and plastic pollution is not gender neutral. Our publication Combatting Global Plastic Pollution presents feminist perspectives for a gender-just approach to the plastic crisis. 

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 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 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.

Microbubbles proposals suggest that by injecting millions of tiny air bubbles into the ocean or spraying sea foam onto surface waters, the albedo of large areas of ocean could be increased, thereby reflecting more sunlight back into space.

Ocean fertilization is a proposed method for CO2 removal in which large quantities of micro- or macronutrients are introduced into marine areas with low biological productivity to stimulate the growth of phytoplankton.

Artificial upwelling aims to artificially pump cooler, nutrient-rich water from the depths of the oceans to the surface in order to stimulate phytoplankton activity and reduce CO2.

Direct Air Capture (DAC) schemes aim to extract carbon dioxide and other greenhouse gases from the atmosphere by chemical and mechanical means, generally using a chemical sorbent and large fans to move air through a filter.

Carbon Capture Use and Storage (CCUS) aims to put carbon dioxide captured from industries such as cement production to an alternative use, such as a feedstock for manufacturing products, where the carbon is then stored.     

Carbon capture and storage (CCS) is a technology proposed for the removal of carbon dioxide, which aims to capture CO2 emitted from processes such as the combustion of fossil fuels and store it underground.
