This Glossary will overtime evolve into a knowledge center for CO2 re-use. You think we are missing something? Get in touch at enco2re@climate-kic.org


  • Carbon Capture Storage

    Carbon capture and storage (CCS), also referred to as carbon capture and sequestration, aims at preventing large amounts of carbon dioxide (CO2) from being released into the atmosphere. This technology involves capturing CO2 from large industrial plants, compressing it for transportation and then injecting it deep into a rock formation where it is permanently stored.


  • Carbon dioxide CO2

    Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth’s atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas. (Source Wikipedia)


  • Carbon dioxide uses

    Carbon dioxide is used by the food industry, the oil industry, and the chemical industry


  • Carbon removal

    Any technology or process that can capture and safely store carbon-based molecules from the atmosphere.


  • Catalysis

    The increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. In most cases, reactions occur faster with a catalyst because they require less activation energy.


  • CCU

    Carbon Capture and Utilization. To use carbon dioxide either directly or in its parts after the separation of the CO2 molecule.


  • Circular economy

    A circular economy is an industrial economy that promotes greater resource productivity aiming to reduce waste and avoid pollution by design or intention, and in which material flows are of two types: biological nutrients, designed to reenter the biosphere safely, and technical nutrients, which are designed to circulate at high quality in the production system without entering the biosphere as well as being restorative and regenerative by design. This is contrast to a Linear Economy which is a ‘take, make, dispose’ model of production.


  • CO2 as Feedstock

    Use CO2 as a feedstock to produce chemicals (including fuels and polymers) and find applications for the end products.


  • CO2 re-use

    To use carbon dioxide either directly or in its parts after the separation of the CO2 molecule.


  • CO2 sequestration

    Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming and avoid dangerous climate change. It has been proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.


  • CO2 transformation


  • CO2 utilization

    Carbon dioxide utilisation is a broad term that covers a variety of innovative industrial processes, which use CO2 from point source emitters (and in the future from direct air capture) as a feedstock to transform CO2 into value added products. Therefore, CO2 is treated as a resource, rather than a waste.


  • Industrial symbiosis

    Industrial symbiosis is an association between two or more industrial facilities or companies in which the wastes or byproducts of one become the raw materials for another.


  • Resource efficiency

    Means using the Earth’s limited resources in a sustainable manner while minimizing impacts on the environment. It allows us to create more with less and to deliver greater value with less input.
