Given that the global winegrape planting area is 7.2×106 hm2, the potential for winegrape crop-mediated carbon capture and storage as an approach to reducing greenhouse gas emissions warranted further research. Herein, we employed an allometric model of various winegrape organs to assess biomass distributions, and we evaluated the carbon storage distribution characteristics associated with vineyard ecosystems in the Hongsibu District of Ningxia. We found that the total carbon storage of the Vitis vinifera ‘Cabernet Sauvignon’ vineyard ecosystem was 55.35 t·hm−2, of which 43.12 t·hm−2 came from the soil, while the remaining 12.23 t·hm−2 was attributable to various vine components including leaves (1.85 t·hm−2), fruit (2.16 t·hm−2), canes (1.83 t·hm−2), perennial branches (2.62 t·hm−2), and roots (3.78 t·hm−2). Together, these results suggested that vineyards can serve as an effective carbon sink, with the majority of carbon being sequestered at the soil surface. Within the grapevines themselves, most carbon was stored in perennial organs including perennial branches and roots. Allometric equations based on simple and practical biomass and biometric measurements offer a means whereby grape-growers and government entities responsible for ecological management can better understand carbon distribution patterns associated with vineyards.

Carbon capture and storage in deep saline aquifers is a promising technology to mitigate anthropologically emitted CO2. Our high-pressure microfluidics can help assess the relevant time-scale and CO2 mass transfer in different reservoir conditions.

Change Mitigation

This article presents an analysis of twenty-six industrialized countries’ support for the carbon-sequestration-based mitigation measures carbon capture and storage (CCS) and reduced emissions from deforestation and forest degradation (REDD+) during the 2007–2014 period. The article explores whether these proposed solutions to climate change share characteristics that make them feasible for reasons that can be observed in cross-national patterns. Insights from political economy, public policy, and international relations form a “triply engaged” theoretical framework. Relationships are tested using bivariate statistics and multivariate regressions. The analysis reveals that the same states show stronger support for both CCS and REDD+, and mostly for the same reasons. Proponents of such measures are generally petroleum-producing, large, and affluent, and they do not take on more ambitious mitigation targets. This article is the first to suggest that the widely different carbon-sink-based mitigation measures CCS and REDD+ may share similar political functions in similar political contexts.

<p>Current scenarios assume that in addition to a rapid reduction in greenhouse gas emissions, land-based carbon mitigation will also be necessary to achieve the targets of the Paris Climate Agreement. Possible measures are increased carbon sequestration via planting new forests, the cultivation of bioenergy crops, possibly in combination with carbon capture and storage (BECCS), or increasing the carbon storage of existing forests. However, currently available scenarios that are in line with IPCC storylines (SSPs, Shared Socioeconomic Pathways and RCPs, Representative Concentration Pathways) usually have  a global  perspective, while in practice mitigation projects have to be realized regionally or locally. Here, we investigate the carbon mitigation potential via alternative management of Bavarian ecosystems using an ecosystem model with an explicit representation of climate impacts and land management. Bioenergy cultivation on existing agricultural land has a larger mitigation potential than reforestation only if combined with carbon capture and storage (BECCS).  The mitigation potential in the forestry sector via alternative management is limited (converting coniferous into mixed forests, nitrogen fertilization) or even negative (suspending wood harvest) due to decreased carbon storage in product pools and associated substitution effects. Overall, the potential for land-based mitigation in Bavaria is limited because the majority of current agricultural lands will still be needed for food production and the forestry sector offers only small per-area carbon mitigation potentials.</p>

Abstract The paper presents the results and analysis of biomass processing in order to provide the conditions for the most profitable use of the biomass in modern and efficient power generation systems with particular attention put on the decrease of the emission of carbon dioxide (CO2) and no need to develop carbon capture and storage plants. The promising concept of CO2 storage via the production of biochar and the advantages of its application as a promising carbon sink is also presented and the results are supported by authors’ own experimental data. The idea enables the production of electricity, as well as (optionally) heat and cold from the thermal treatment of biomass with simultaneous storage of the CO2 in a stable and environmentally-friendly way. The key part of the process is run in a specially-designed reactor where the biomass is heated up in the absence of oxygen. The evolved volatile matter is used to produce heat/cold and electricity while the remaining solid product (almost completely dry residue) is sequestrated in soil. The results indicate that in order to reduce the emission of CO2 the biomass should rather be ‘cut and char’ than just ‘cut and burn’, particularly that the charred biomass may also become a significant source of nutrients for the plants after sequestration in soil.

Carbon capture and storage (CCS) is one of the number of approaches to mitigating climate change by reducing the emission of greenhouse gases (GHGs) into the atmosphere. It involves capturing carbon dioxide (CO2) emissions from large point sources such as power plants, prior to compressing, transporting, and storing it securely in geological formations. The CO2 emitted is thus prevented from entering the atmosphere. CCS is believed, by many, to have massive potential to significantly reduce GHG emissions, with the UN's Intergovernmental Panel on Climate Change suggesting that CCS could contribute between 10 and 55 per cent of the world's total carbon mitigation effort until 2100. This article considers the principal impediments to the development of CCS projects and the steps taken in the European Union (EU) to overcome them. The development of CCS requires not only the establishment of adequate funding mechanisms and, most likely, the existence of consistently higher carbon prices than those prevail today, but also the settlement of a number of key legal issues. Although much further work is required on the part of legislators, a regulatory framework for CCS is slowly growing in various jurisdictions, especially in the EU where a large step forward was taken in December 2008 with the passing of a CCS Directive.

The inherent uncertainty in information about the Earth's subsurface requires experts to interpret and reach judgements about geological data based on their individual experience and expertise. This is particularly true for the geological storage of CO2 in subsurface saline aquifers where the fate of the injected CO2 needs to be predicted far into the future. In this chapter, linear modelling is used in a structured elicitation exercise to estimate the relative influence of individual experts within a group and to assess whether a group consensus reflects a genuine shared opinion or is biased towards or away from any dominant member or subgroup. The method is applied to a real expert evaluation of the carbon storage potential of a siliciclastic formation. This reveals herding behaviour amongst the experts, and levels of inter-expert influence that are undue given individual experts' levels of expertise, though neither phenomena was apparent during the meeting.
