TL;DR: In this paper, the main strategies for climate change abatement, namely conventional mitigation, negative emissions and radiative forcing geoengineering, are reviewed, and it is evident that conventional mitigation efforts alone are not sufficient to meet the targets stipulated by the Paris agreement; therefore, the utilization of alternative routes appears inevitable.

TL;DR: In this article , the authors present a strategy to reach a carbon neutral economy by examining the outcome goals of the 26th summit of the United Nations Climate Change Conference of the Parties (COP 26).

TL;DR: In this article , the authors review application of biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, and energy storage.

TL;DR: A techno-economic study is carried out on the potential of biogas production from different types of food waste generated locally and polynomial models were used to predict the production of total gas and methane during the fermentation periods, which showed good matching between the theoretical and practical values.

TL;DR: The major commercialized technologies for offering atmospheric carbon removal are forestation, direct air carbon capture utilization and storage, soil carbon sequestration, wooden building elements and biochar, with corresponding fees ranging from 10 to 895 GBP (British pounds) per ton CO2.
