Carbon Nanomaterials for the Removal of Endocrine-Disrupting Chemicals
The large-scale production and frequent use of endocrine-disrupting chemicals (EDCs) have led to the continuous release and wide distribution of these pollutions in the natural environment. At low levels, EDC exposure may cause metabolic disorders, sexual development, and reproductive disorders in aquatic animals and humans. Adsorption treatment, particularly using nanocomposites, may represent a promising and sustainable method for EDC removal from wastewater. EDCs could be effectively removed from wastewater using various carbon-based nanomaterials, such as carbon nanofiber, carbon nanotubes, graphene, magnetic carbon nanomaterials, carbon membranes, carbon dots, carbon sponges, etc.

Carbon Polygons and Carbon Offsets
The most important area of study concerning carbon polygons is the problem of assessing the reserves and trends in the stability of organic matter in the soil of natural ecosystems. An adequate assessment of these stocks should be based on verified methods for determining the content of organic matter (direct and indirect methods and the problem of the correlation of results) and on unified ideas about the depth and regularity of sampling within soil profiles and monitoring sites. This problem is particularly relevant to the development of a spatial network of carbon polygons in the Russian Federation.

Carbon Potential of Green Hydrogen
As a potential storage material, hydrogen (H2) is considered to be promising and considerable research has been invested into this matter. Scientists and industry discriminate between different colors of hydrogen depending on the method of production: Green hydrogen, for example, implies that production is (almost) CO2-neutral using e.g., bio gas or renewable energies such as wind power; whereas gray hydrogen is produced using fossil fuels such as oil or gas. Turquoise hydrogen implies using methane pyrolysis fueled by renewable energy sources, i.e., it is also considered to be CO2-neutral.

Carbon Reduction and Pollution Control Effect of IIG
The coordinated promotion of pollution control and carbon reduction is intended to build a more beautiful China. Intelligent industrial technology plays an important role in the fight against climate change and in improving the ecological environment. Based on panel data from 30 provinces in China from 2006 to 2020, researchers used a two-way fixed effects model to evaluate the synergistic effects of industrial intelligent transformation on pollution control and carbon reduction and its mechanisms.

Carbon Sequestration
Carbon sequestration or carbon dioxide removal (CDR) is the long-term removal, capture or sequestration of carbon dioxide from the atmosphere to slow or reverse atmospheric CO2 pollution and to mitigate or reverse global warming. Carbon dioxide (CO2) is naturally captured from the atmosphere through biological, chemical, and physical processes. These changes can be accelerated through changes in land use and agricultural practices, such as converting crop and livestock grazing land into land for non-crop fast growing plants. Artificial processes have been devised to produce similar effects, including large-scale, artificial capture and sequestration of industrially produced CO2 using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks, bio-energy with carbon capture and storage, biochar, ocean fertilization, enhanced weathering, and direct air capture when combined with storage. The likely need for CDR has been publicly expressed by a range of individuals and organizations involved with climate change issues, including IPCC chief Rajendra Pachauri, the UNFCCC executive secretary Christiana Figueres, and the World Watch Institute. Institutions with major programs focusing on CDR include the Lenfest Center for Sustainable Energy at the Earth Institute, Columbia University, and the Climate Decision Making Center, an international collaboration operated out of Carnegie-Mellon University's Department of Engineering and Public Policy.

Carbon Sequestration as a Climate Change Mitigation Strategy
Agriculture is the second-highest, after energy use, source of greenhouse gas emissions, which are released from soils and animal digestion processes and as a result of energy consumption at various stages of agricultural production. However, changes in the management of agricultural systems may mitigate the negative impact of this sector on the atmosphere and climate. Carbon farming, which focuses on carbon sequestration, is closely linked to soil quality. Carbon converted to organic form in the soil stimulates the activity of soil enzymes, promotes the growth of beneficial microorganisms and improves chemical and physicochemical properties, including pH, sorption capacity and water retention.

Carbon Sequestration by Biofuel Crop Switchgrass
Under the macroenvironmental background of global warming, all countries are working to limit climate change. Internationally, biofuel plants are considered to have great potential in carbon neutralization. Several countries have begun using biofuel crops as energy sources to neutralize carbon emissions. Switchgrass (Panicum virgatum) is considered a resource-efficient low-input crop that produces bioenergy.

Carbon Sequestration in Soil
The agroforestry systems with a high potential for carbon (C) sequestration are those degraded by poor management strategies. Studies on changes in soil C status in these ecosystems mostly take into account labile C pools. Labile and stable soil organic matter (SOM) fractions are affected by soil management and land-use changes. Stable C pools are essential to understanding effects of land-use on soil C storage in the long term.

Carbon Source and Sink in Arable Land Ecosystems
As a subsystem of terrestrial ecosystems, the arable land ecosystem is most closely related to human beings because it not only provides food, fiber, fuel and other products, but also supports and maintains the natural environment on which human beings depend for survival. An arable land ecosystem can act as either a carbon source or a sink.

Carbon-Based Nanomaterials Biodegradation
Carbon-based nanomaterials (CNMs) have attracted a growing interest over the last decades. They have become a material commonly used in industry, consumer products, water purification, and medicine. The knowledge about the biodegradation of nanomaterials will facilitate the development of the principals of “biodegradable-by-design” nanoparticles which have promising application in medicine as nano-carriers and represent lower toxicity and risks for living species and the environment.
