While captured CO2 can be used in fuels, building materials, and chemicals, directly applying it to enhance agricultural yields through atmospheric application is not a primary utilization pathway for captured CO2.

Direct Air Capture (DAC) refers to technologies that remove carbon dioxide directly from the surrounding air, rather than from a point source of emission.

Traditional CCUS systems typically capture CO2 from concentrated sources like emissions from power plants and heavy industrial processes.

CCUS is an acronym for Carbon Capture, Utilization, and Storage, a set of technologies aimed at reducing CO2 emissions.

The negotiations are being carried out through a series of Intergovernmental Negotiating Committee (INC) meetings, bringing together representatives from UN member states.

A successful treaty is expected to foster a circular economy for plastics, where materials are reused, recycled, and repurposed, minimizing waste and environmental impact.

The treaty's ambition is to cover the entire lifecycle of plastics, encompassing production, design, consumption, waste management, and remediation of pollution.

A significant disagreement among member states revolves around whether the treaty should focus primarily on managing plastic waste or also include measures to limit the production of plastics.

The United Nations Environment Programme (UNEP) is spearheading the negotiations for a legally binding global treaty to address plastic pollution.

Cheetahs are apex predators in grassland ecosystems, and their reintroduction is vital for maintaining the health and balance of these habitats.
