A Review of the Role of Vegetal Ecosystems in CO2 Capture

Abstract

Abstract:The reduction of carbon emissions is a worldwide global challenge and represents the objective of many scientists that are trying to modify the role of carbon, turning a problem into an opportunity. The potential of CO 2 capture and storage by vegetal species is significant because of their capacity to absorb exceeding carbon emission. The purpose of the present paper is to draw a picture of the role of vegetal ecosystems on carbon fixation by identifying the most significant scientific contributions related to the absorption by vegetal species. In particular the aim of this paper is to examine different forms of CO 2 sequestration made by plants and crops involved in reducing greenhouse gas (GHG) emission. Results highlight the important role played by agricultural soils, forests, perennial plants, and algae, looking at the overall reduction of carbon emissions. In addition, results show that some bioenergy crops allow substantial storage of carbon dioxide, providing a significant contribution to climate change mitigation.

Plant Power: Opportunities and challenges for meeting sustainable energy needs from the plant and fungal kingdoms

“…There has been significant research into the role of perennial plants such as Miscanthus in enhancing carbon capture and storage (e.g., Agostini, Gregory, & Richter, 2015), although in the context of energy crops this has tended to concentrate on the restricted set of species listed in Box 1 and shown in Figure 4c. This research suggests that while currently used perennial energy crops may not impact soil organic carbon levels (Ferchaud, Vitte, & Mary, 2016; Ye & Hall, 2020), they do positively impact carbon draw‐down and storage within the plant, but choice of species is critical to achieve carbon capture outcomes (Di Vita, Pilato, Pecorino, Brun, & D’Amico, 2017). We propose that a diversity‐driven approach to plant and fungal energy sources could also involve research to identify novel perennial taxa that simultaneously maximize carbon capture and storage while a standing crop.…”

Enhanced CO2 Adsorption by Nitrogen-Doped Graphene Oxide Sheets (N-GOs) Prepared by Employing Polymeric Precursors

“…In order to overcome this problem, efforts are being made throughout the world to curb pollutions by replacing fossil fuels with other sources of sustainable energy. Apart from this, there are efforts such as afforestation and reforestation for the consumption of CO 2 from the environment [ 2 ]. Other than this, there are attempts being made to enable adsorption of CO 2 into materials, which is also known as CO 2 capture and sequestration (CCS) technology, which can be employed further for the generation of electricity [ 3 , 4 , 5 , 6 , 7 ].…”

Energetic and Economic Analyses for Agricultural Management Models: The Calabria PGI Clementine Case Study

“…As previously mentioned, the I farming system represented the scenario with the second least amount of impact in terms of energy consumption, although it had a higher "fossil energy" requirement than that of the other two farming systems. Based on sustainable development, non-renewable energy sources should be conserved and an attempt should be made to replace them with renewable energy sources [43]. The ratio of this energy category consumption to the total requirement was similar to that of the O farming system but was not similar to that of the other categories (i.e., a higher ratio for "non-renewable, nuclear" and lower ratio for "renewable, water").…”
