There was the first joint meeting of the year to study the reduction of carbon in the air from land use. I am in charge of the Indonesian case and will be studying how decarbonisation can be done with biogas plants and composting. I may also research decarbonisation using agroforestry, agriculture in forestry, based on yesterday's talk. I have already written three methods, biogas, composting and agroforestry. Still, I summarise what other decarbonisation methods are available. This categorisation is also an extract from the LANDMARC document.
Negative Emissions Technologies and Practices (NETPs) can be referred to as Carbon Dioxide Removal (CDR) technologies. Energy-saving technologies and renewables such as wind and solar power are not technically NETPs because they do not remove carbon dioxide. It is impossible to eliminate all greenhouse gases such as carbon dioxide even if energy-saving measures are dominated. Therefore, to achieve its goal of becoming climate neutral by 2050 in the European Union (EU), NETPs are needed to offset the rest of its emissions.
NETPs are divided into technologies and practices. Negative emission technologies (NETs) are further classified into biomass/photosynthesis-based and non-biomass/photosynthesis-based technologies. Among the biomass-related ones, there is biochar, which carbonises waste and other materials and Bio-Energy with Carbon Capture and Storage (BECCS) (BECCS).
Negative Emission Practices are further subdivided based on how they are operated and managed on land and in the sea. su-re.co's Indonesian case is working on decarbonising land use including bioenergy production (including biogas) and Agriculture, Forestry and Other Land Use (AFOLU) (including agroforestry and composting). In land use, technologies such as biochar may be employed in land management. BECCS also uses biofuels to decarbonise the air and then burns the biofuels to produce energy, but without emitting carbon dioxide into the air. Therefore, NTPs would be more effective with innovative technologies such as biochar, and BECCS would be useless without biofuels. In other words, NETs and NEPs should be considered together.
