Terlouw, Tom; et al. (2021): Life cycle assessment of carbon dioxide removal technologies: a critical review

Terlouw, Tom; Bauer, Christian; Rosa, Lorenzo; Mazzotti, Marco (2021): Life cycle assessment of carbon dioxide removal technologies: a critical review. In Energy & Environmental Science. DOI: 10.1039/D0EE03757E.

"We present a critical review on conducted Life Cycle Assessments (LCAs) of a comprehensive set of CDR technologies: afforestation and reforestation, biochar, soil carbon sequestration, enhanced weathering, ocean fertilisation, bioenergy with carbon capture and storage, and direct air carbon capture and storage."

Friggens, Nina L.; et al. (2020): Tree planting in organic soils does not result in net carbon sequestration on decadal timescales

Friggens, Nina L.; Hester, Alison J.; Mitchell, Ruth J.; Parker, Thomas C.; Subke, Jens-Arne; Wookey, Philip A. (2020): Tree planting in organic soils does not result in net carbon sequestration on decadal timescales. In Glob Chang Biol 26 (9), pp. 5178–5188. DOI: 10.1111/gcb.15229.

"We show that planting two native tree species (Betula pubescens and Pinus sylvestris), of widespread Eurasian distribution, onto heather (Calluna vulgaris) moorland with podzolic and peaty podzolic soils in Scotland, did not lead to an increase in net ecosystem C stock 12 or 39 years after planting."

Di Sacco, Alice; et al. (2021): Ten golden rules for reforestation to optimize carbon sequestration, biodiversity recovery and livelihood benefits

Di Sacco, Alice; Hardwick, Kate A.; Blakesley, David; Brancalion, Pedro H. S.; Breman, Elinor; Cecilio Rebola, Loic et al. (2021): Ten golden rules for reforestation to optimize carbon sequestration, biodiversity recovery and livelihood benefits. In Glob Chang Biol. DOI: 10.1111/gcb.15498.

"Here, we highlight the main environmental risks of large‐scale tree planting and propose 10 golden rules, based on some of the most recent ecological research, to implement forest ecosystem restoration that maximizes rates of both carbon sequestration and biodiversity recovery while improving livelihoods. These are as follows: (1) Protect existing forest first; (2) Work together (involving all stakeholders); (3) Aim to maximize biodiversity recovery to meet multiple goals; (4) Select appropriate areas for restoration; (5) Use natural regeneration wherever possible; (6) Select species to maximize biodiversity; (7) Use resilient plant material (with appropriate genetic variability and provenance); (8) Plan ahead for infrastructure, capacity and seed supply; (9) Learn by doing (using an adaptive management approach); and (10) Make it pay (ensuring the economic sustainability of the project)."

Borgen Magazine: Drone Reforestation: How New Tech Is Rehabilitating Forests

"DroneSeed advertises carbon capture as the primary benefit of its technology. The company believes that the use of carbon credits (a form of negative emissions utilized by industry to meet regulatory requirements) could further enhance the economic argument for investment in drone reforestation."

Project: Reforestation Hub

"This map shows county-level estimates of the potential area of new forests (“area of opportunity” in units of acres) and how much carbon those areas could capture (in units of metric ton of carbon dioxide per year). We focused on finding lower cost and more feasible options for restoring forest cover, which included lands already in a natural land use, more marginal agricultural lands, or areas where trees have the potential to provide high additional co-benefits beyond carbon capture, such as flood mitigation or urban cooling."
