The Carbon Removal Budget: theory and practice

Carbon Management, Год журнала: 2024, Номер 15(1)

Carbon dioxide removal (CDR) is a necessary complement to emissions reductions achieve state of global net zero and stabilise future warming. Despite its utility, CDR remains poorly understood. Due range constraints, fundamentally finite resource, which we currently do not have enough go beyond zero. This has wide-ranging but underexplored implications for the technical economic feasibility our collective transition. At same time, both opportunity obligation undertake are equally distributed amongst actors geographies. As result, there ongoing questions as how can increase supply quality whilst at time ensure equitable distribution that CDR, within between countries non-state actors. To explore these phenomena, introduce define concept Removal Budget (CRB), illustrate it apply different contexts scales, distinguish from related distinct carbon budget. We further estimate CRB, review constraints considerations outline potential utilisation pathways principles. then examine application CRB tool on public private decision-makers use assess their nationally determined contributions and/or net-zero transition plans. In this manner, forecasts be used today help build tomorrow.

Area demand quantification for energy system-integrated negative emissions based on carbon dioxide removal portfolios

Environmental Research Letters, Год журнала: 2025, Номер 20(5), С. 054064 - 054064

Abstract Climate change mitigation will most likely rely on large-scale carbon dioxide removal (CDR). Often, only a few technology options are used, principally bioenergy, capture and sequestration, as well afforestation reforestation. If climate is based energy crops, the impact of CDR area demand may be significant. The CDR-specific usually not presented. This study compares portfolio prioritising biomass-based solutions to portfolios low cost, demand, high security, readiness in terms demand. model linked with an system include required for solar photovoltaics wind power supply whole energy–industry–CDR system. A quantitative qualitative comparison made using definitions gross net differentiation routes into biogenic, bio-technical, technical options. Gross differentiate total area, including spacing or gathering areas (gross) built-up (or unsuitable biodiversity) (net). We consider demands 500 GtCO 2 1.5°C target 1750 1.0°C by 2100. results indicate advantage regarding compared from crops. Including does lead significant can kept at ca. 1.0% (1.5°C) below 1.4% (1.0°C) land except biomass-prioritising portfolio, which has 3% both targets. Biogenic biotechnical estimated require up 9.7% today’s global cropland end century (net area). additional versus comparably small.

Construction Land Transfer Scale and Carbon Emission Intensity: Empirical Evidence Based on County-Level Land Transactions in Jiangsu Province, China

Land, Год журнала: 2024, Номер 13(7), С. 917 - 917

Опубликована: Июнь 24, 2024

The expansion of the construction land scale has been vital in supporting rapid economic development and meeting social needs. However, spatial heterogeneity effect on carbon emission intensity at county level remains underexplored. Therefore, comprehensively investigating relation between transfer holds substantial research value. Using panel data from 2007 to 2021, this study analyzes spatiotemporal differentiation characteristics Jiangsu Province, China. findings reveal that Province generally exhibits a continuous downward trend over time distribution characterized by gradual decrease southern counties central northern counties. Moreover, there is significant positive intensity, conclusion supported robustness tests. Furthermore, mediating analysis indicates reduction promoting green technology innovation industrial structure upgrading, which, turn, inhibitory intensity. impact different sources, supply methods, types, strength heterogeneity.

Quantifying the Transformational Requirements of the Electricity Sector Under Uncertain Expectations of Carbon Removal

Decarbonization and carbon dioxide removal (CDR) are crucial for achieving global climate targets. The power sector is pivotal in this process, yet the role of CDR deep decarbonization its implications on have been underexplored. Using a multi-sector model, we quantify effects transformation under different reliance levels by 2050 — high (4–10 Gt/yr), moderate (2.5-5 low (≤ 1Gt/yr)—aligned with 1.5°C 2°C We show that BECCS essential future electricity demands, particularly Asia Central America. High pathways could require 10–20% consumption South America Australia/New Zealand removal. Major economies like China, US, India face significant investment needs, risking stranded assets worth up to US$165–225 billion mid-century compared CDR. Regions heavily dependent coal, such as China India, greater stranding costs, while gas-dependent regions Middle East Russia relatively lower costs. Global mitigation efforts limited 15% reduction committed emissions high-CDR scenarios, most pronounced 65% anticipated India.
