Impact of Biogenic Carbon Neutrality Assumption for Achieving a Net-Zero Emission Target: Insights from a Techno-Economic Analysis

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(29), P. 10615 - 10628

Published: July 11, 2023

Global pathways limiting warming to 2 °C or below require deep carbon dioxide removal through a large-scale transformation of the land surface, an increase in forest cover, and deployment negative emission technologies (NETs). Government initiatives endorse bioenergy as alternative, carbon-neutral energy source for fossil fuels. However, this neutral assumption is increasingly being questioned, with several studies indicating that it may result accounting errors biased decision-making. To address growing issue, we use budget model combined system model. We show including sequestration alleviates decarbonization effort. discuss how management strategy high capacity reduces need expensive technologies. This study indicates necessity establishing most promising before investing capture storage. Finally, describe neutrality lead decision-making because allows more biomass without constrained by biogenic CO2 emissions. The risk higher regions have lower coverage, since available cannot sink emissions short term, importing could worsen situation.

Economic factors influence net carbon emissions of forest bioenergy expansion

Communications Earth & Environment, Journal Year: 2023, Volume and Issue: 4(1)

Published: Feb. 17, 2023

Abstract There is considerable concern that consuming forest biomass for energy will increase net carbon emissions from forests, which defined as debt. Using a market-based economic model, we test the effects of 51 demand pathways bioenergy on future stocks to assess likelihood incurring sustained debt lasting several decades. We show potential expansion, measured near-term decrease in sequestration relative baseline, occurs and persists only under specific set assumptions about accounting, markets, policies, demands. Finally, evaluate whether regulations restricting sourcing could influence scale and/or reduce time needed recover (payback period). similar absence direct imposing limits supply likely payback period but does not avoid initial

Spatiotemporal Evolution and Driving Mechanisms of Forest Tourism in Henan, Central China

Forests, Journal Year: 2025, Volume and Issue: 16(3), P. 483 - 483

Published: March 10, 2025

Forest tourism is a vital avenue for promoting green consumption and constitutes significant part of ecotourism in China. Its development offers substantial economic, social, ecological benefits. Balancing regional economic growth conservation requires analyzing its spatiotemporal evolutionary patterns driving factors. This study established comprehensive dynamic index system to evaluate the forest level (FTDL) 18 prefecture-level cities Henan Province from 2018 2021. Exploratory spatial data analysis geographical detector model were employed examine evolution identify underlying mechanisms. The key findings are as follows: (1) temporal FTDL exhibited “stratified heterogeneity small fluctuations”, while distribution followed “high southwest low east” pattern; (2) over time, autocorrelation shifted positive negative, with gradual decline correlation strength; (3) eight dominant drivers categorized into four groups identified, revealing shift forces environmental supports formulation political strategies harmonize development.

Investing in U.S. forests to mitigate climate change

Carbon Balance and Management, Journal Year: 2025, Volume and Issue: 20(1)

In recent years several U.S. federal policies have been adopted to support forest-based climate mitigation actions. This study focuses on current funds allocated forest for change activities assess how much they could deliver in terms of net sequestration under a best-case (optimized) scenario where the cheapest abatement options are implemented first and if these line achieve domestic targets 2030 2050. Multiple investments pathways tested two different assumptions CO2 fertilization provide range future projections from forests. Results show that annual with (around $640 million), expected carbon flux forests is around 745 MtCO2/yr (+ 12% increase baseline) expand after be 786 2050 17% baseline). When accounted for, by about 1 GtCO2 achieved 2050, increasing likelihood meeting both short-term long-term targets.

Application of multispectral UAV to estimate mangrove biomass in Vietnam: A case study in Dong Rui commune, Quang Ninh Province

One Ecosystem, Journal Year: 2023, Volume and Issue: 8

Published: July 10, 2023

Mangroves play an important role in coastal estuarine areas with different ecological functions, such as reducing the impact of waves and currents, accumulating biomass sequestering carbon. However, estimation terrestrial mangrove areas, especially Vietnam, has not been fully studied. The application unmanned aerial vehicles (UAV), mounted multispectral cameras combined field verification is effective method for estimating mangroves, it reduces survey time allows greater spatial range research. In this study, ground was estimated area Dong Rui commune, based on image data obtained from UAV results 16 standard cells measuring actual according to four regression models: Log-Log, Log-Lin, Lin-Log Lin-Lin. comparing these models show that log-log model highest accuracy a high correlation coefficient (R 2 = 0.831). Based analysis selection ground-based models, map established flying forest values ranging 20 Mg/ha 150 Mg/ha. summary, we present through basic linear ultrahigh-resolution UAV. resulting research can serve basis managers calculate synchronise payment carbon services, thus contributing effectively promoting livelihoods local people.

Land-Based Carbon Effects and Human Well-Being Nexus

Land, Journal Year: 2024, Volume and Issue: 13(9), P. 1419 - 1419

Published: Sept. 3, 2024

In light of international climate agreements and the Sustainable Development Goals (SDGs), there is a growing need to enhance understanding linkages among land use/cover change (LUCC) its carbon effects (CEs), as well human well-being (HW). While existing studies have primarily focused on impacts LUCC CEs or ecosystem services, remains gap in systematically elucidating complex relationships LUCC, CEs, HW. This paper presents comprehensive review nexus between land-based HW, examining: (1) correlation encompassing methodologies for investigating CEs; (2) association introducing concept “low-carbon well-being” evaluation framework; (3) proposed framework “LUCC-CEs-HW,” which delves into intricate connections three elements. The study identifies research gaps outlines potential future directions, including assessments low-carbon exploration “LUCC-CEs-HW” nexus, development standardized measurement approaches. Key opportunities further investigation include establishing unified index system developing scalable methods. elucidates offering insights works.
