This study uses multi-regional input-output tables (1995-2015) to examine how global value chain (GVC) participation influences carbon emissions. It finds a strong link between backward GVC orientation (upstream sourcing) and emissions, emp…

Lu Li, Stephen Obinozie Ogwu, Afamefuna A. Eze +1

This study examines the joint effects of R&D investment and trade openness on renewable energy transition across 18 OECD countries from 2010 to 2023. Using bootstrap quantile regression and CS-ARDL, it finds that R&D has positive effects at…

Rongshen Lai, Liu Z, Hang Zhang +1

This paper proposes a key technology system for emission reduction and carbon sink enhancement oriented towards China's dual-carbon goals. It is policy-oriented, though specific technologies and findings are unclear from the title.

Gaetano Iaquaniello, Gabriele Centi

This paper proposes a hydrogen energy efficiency index to compare low-carbon hydrogen production technologies and assess their potential for carbon-negative operation. It quantifies energy efficiency across various hydrogen production pathw…

Xianfeng Hu, Lena Sundqvist Ökvist, Guozhu Ye +1

This review examines pathways and challenges for carbon-neutral steelmaking. It explores the use of renewable electricity, hydrogen, and biocarbon as reducing agents and heat sources to transform conventional processes. Key constraints incl…

Accounting for foregone production in farm-level climate interventions is critical; ignoring it may overstate net benefits. This study highlights the importance of opportunity costs in carbon accounting.

Yang Ye, Feng Dong (142012), 边祥海 +8

This study developed a novel photobiohybrid system that efficiently synthesizes the aviation fuel precursor epi-isozizaene from CO2. Using a bifunctional catalyst of iron single atoms on nitrogen-doped carbon quantum dots (Fe-NC QDs), CO2 i…

Julián Atilio Puszkiel

This review covers hydride-based materials and renewable energy systems for hydrogen storage and CO2 conversion. Metal hydrides offer efficient, compact hydrogen storage under mild conditions, enabling power-to-gas-to-power concepts. The wo…

Komal Bamugade and Archana Jadhav

This review systematically examines AI (ML, deep learning, etc.) applications in climate change modeling and prediction, with emphasis on improving carbon footprint accuracy and climate pattern understanding. It identifies challenges like d…

Sellami O, Youssef SB

This study examines the effect of government R&D spending on fossil energy consumption (FEC) in G7 countries (1990-2023) using MMQR. Findings show that renewable energy R&D (RDR) significantly reduces FEC, especially at lower quantiles, whi…

Suh S, Xie X, Xu M

This paper compiles a facility- and corporate-level GHG emissions inventory for global AI hardware manufacturing and AI data center operations. Under market-based accounting, AI hardware manufacturing emitted 5–7 Mt CO2e/yr in 2024, exceedi…

Bernabeu Santisteban, Andrés, Dadjo Tavakoli, Saman, del Pozo Gonzalez, Hector +3

This paper develops a hybrid dynamical modeling framework for hydrogen electrolyzers (HEs) operating under Frequency Sensitive Mode (FSM) and Virtual Synchronous Mechanism (VSM). Using a 17.5 MW Siemens Silyzer 300 case study, it shows cell…

Biffi, Sofia, Chapman, Pippa, Grayson, Richard +1

This study evaluates the impact of planting hedgerows on soil organic carbon accumulation in agricultural landscapes. Results show consistent carbon storage under hedges, driven by increased light particulate organic matter, contributing to…

Rashad Tariyel ALIYEV

This study empirically examines the effectiveness of Pigouvian environmental/carbon taxes in reducing CO₂ emissions in G7 countries from 1994 to 2014. Using second-generation panel methods, it finds a long-run cointegration relationship and…

Leo Themjung Makan, Navin Chettri, Kailash Chandra Kabra

This study examines the relationship between carbon disclosure and carbon performance using Fortune Global 500 data. It investigates moderating effects of environmental exposure, certification, and committee. Findings show a significant lin…
