Associated gas carbon asset development refers to the process of obtaining emission reductions through the recovery and utilization of oilfield associated gas.

Forestry carbon sink is a process of participating in forestry resource transactions through market-based means, thereby generating additional economic value. This economic value includes two aspects: forest management carbon sink and afforestation carbon sink.

Arable land carbon sink refers to the use of photosynthesis of plants to absorb carbon dioxide in the atmosphere through agricultural activities, convert it into organic matter and store it in the soil, thereby reducing the concentration of carbon dioxide in the atmosphere and slowing down the emission of carbon dioxide in the atmosphere.

Grassland carbon sink refers to the process in which grassland ecosystems convert atmospheric carbon dioxide into carbohydrates through plant photosynthesis and fix it in the form of organic carbon in plants or soil, thereby reducing the concentration of carbon dioxide in the atmosphere. Grassland ecosystem is one of the most widely distributed vegetation types on the earth. It has a strong carbon sink function and plays an irreplaceable and important role in responding to global climate change.
