Electrocatalysts constantly experience structure evolution during CO₂RR, directly affecting activity, selectivity, and long-term durability. In this review, researchers explain how atomic migration, redox transitions, and surface restructuring determine catalytic performance, and highlights advanced in-situ characterization techniques for decoding these dynamic processes. Understanding such reconstruction mechanisms plays a key role in designing robust catalysts for industrial CO₂ conversion.

Forest restoration, a critical strategy for mitigating climate change and rejuvenating natural ecosystems, is a global priority, with the Intergovernmental Panel on Climate Change (IPCC) targeting substantial atmospheric carbon removal through these efforts. However, understanding the factors that govern the recovery of soil organic carbon (SOC) – the largest terrestrial carbon pool – has remained a complex challenge. A comprehensive global meta-analysis, led by Shan Xu and Junjian Wang from the Southern University of Science and Technology with international collaborators including Nico Eisenhauer from the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig, now clarifies these crucial drivers, offering vital insights for effective climate change mitigation strategies.

A new investigation led by researchers at the African Centre of Excellence in Future Energies and Electrochemical Systems (ACE-FUELS) at the Federal University of Technology, Owerri, provides a detailed molecular-level blueprint for using Nigerian coal deposits to simultaneously capture carbon dioxide (CO₂) and enhance natural gas production. The work by Victor Inumidun Fagorite and his colleagues offers a scientific foundation for implementing CO₂-Enhanced Coalbed Methane (ECBM) technology, a process with significant economic and environmental potential for the nation.

A team of researchers from Guizhou University has published a comprehensive review on the synthesis and application of catalysts derived from a ubiquitous and challenging source: solid waste. The paper synthesizes a vast body of research to demonstrate how materials like industrial sludge, agricultural residue, and metal-containing byproducts can be converted into valuable solid waste-derived carbonaceous catalysts (SW-CCs). This work, authored by Tao Jiang, Bing Wang, Masud Hassan, and Qianqian Zou, provides a critical overview of how these advanced materials can address pressing environmental and energy challenges, offering a viable pathway toward a circular economy.

The increasing global demand for sustainable energy and carbon materials, alongside pressing environmental concerns, necessitates innovative approaches to resource management. Biomass, a versatile renewable resource, offers significant potential for conversion into biochar, an alternative fuel and valuable carbon material. However, efficiently transforming diverse biomass types into high-quality biochar remains a challenge. A recent investigation, conducted by Zhilong Yuan, Ye Wang, Lingfeng Zhu, Congcong Zhang, and Yifei Sun from Beihang University and Hainan University, addresses this by developing a sophisticated machine-learning framework to optimize biochar production from aquatic biomass. This work bridges a crucial gap, as previous modeling efforts largely overlooked aquatic sources.

A new economic analysis from Pandit Deendayal Energy University provides compelling evidence that financial development and digitalization are key drivers in reducing carbon dioxide emissions across six major Mediterranean countries. The research, authored by Dhyani Mehta and published in Carbon Research, examines nearly three decades of data to understand the complex relationship between economic activity and environmental impact, revealing that while some growth factors increase emissions, others offer a promising route to decarbonization.

Agricultural systems worldwide face increasing pressure to enhance productivity while mitigating environmental impact, particularly regarding greenhouse gas emissions linked to fertilizer use. The production and application of nitrogen fertilizers account for a substantial portion of agriculture's carbon footprint. Addressing this challenge, a collaborative research effort from Shenyang Agricultural University explored a novel approach: utilizing monosodium glutamate waste liquid residue (MSGWLR) as a complete or partial substitute for conventional chemical nitrogen fertilizers in rice cultivation. This investigation sought to quantify the effects on rice yield, quality parameters, and crucially, the overall carbon emissions associated with rice production, proposing a pathway toward cleaner agricultural and industrial practices.

Achieving national carbon neutrality targets necessitates precise and reliable carbon accounting across all sectors, particularly in waste management. As municipal solid waste incineration (MSWI) plants expand globally, their role in energy generation and waste reduction is balanced against the imperative to accurately quantify greenhouse gas emissions. Traditional accounting methods often encounter challenges with the heterogeneous nature of waste, evolving waste composition due to sorting initiatives, co-incineration practices, and the underestimation of inert materials. Researchers from Tongji University and the Shanghai Institute of Pollution Control and Ecological Security have developed an advanced methodology that significantly improves the accuracy of direct carbon emission calculations from waste incineration, a critical step towards enhancing sustainable waste management strategies and furthering carbon neutrality efforts.

The global surge in automotive industry growth presents an escalating challenge: the disposal of billions of end-of-life tyres (ELTs) annually. These durable, complex materials resist natural degradation, posing significant environmental and societal burdens. To address this mounting problem, a recent comprehensive review meticulously examines cutting-edge thermochemical processes as a viable pathway to transform ELTs into valuable products, thereby fostering a more circular economy.

Published in Carbon Research, the article meticulously synthesizes advancements in thermochemical techniques, specifically focusing on gasification, pyrolysis, and incineration. Researchers delved into the primary by-products of these processes, including oil, gas, and char, assessing their energy efficiency, product yield, and overall environmental footprint. The study clarifies the intricate correlations between diverse process parameters and the resulting composition, yield, and quality of these recovered materials, providing a robust foundation for future applications.
