Summary: The Intergovernmental Panel on Climate Change's mitigation scenarios database is a valuable resource for policymakers, but there are variations in models and scenario designs. This analysis focuses on scenarios with warming limited to 2 degrees C or below, examining the feasibility and trajectory of different fossil fuel reduction pathways. The findings emphasize the importance of clear reduction benchmarks in coal, oil, and gas production and use, along with other climate mitigation targets.

Summary: Climate policy analysis requires reference scenarios to assess emission targets and trends. Countries often compare their target trajectories to fictitious baselines when presenting their national climate policies. Independent modeling groups can provide different interpretations through scenarios, offering a more realistic backdrop for evaluating projected emission trajectories.

Summary: The study found that secondary copper has the potential to replace primary copper as a major component of future copper production. Copper in-use stock shows a peaking trend, while the flow intensity is projected to show an overall decreasing trend. The increase in recovery level contributes positively to copper production.

Summary: Cities are monitoring atmospheric CO2 to evaluate climate policies. In New York City, vegetation within developed land covers plays a crucial role in regional biogenic CO2 fluxes. The type of vegetation, such as grassland or forest, significantly impacts CO2 estimates. Accurate characterization of urban vegetation is essential for effective atmospheric monitoring.

Summary: This study evaluates the contribution of sustainable pyrogenic carbon capture and storage (PyCCS) to negative emissions (NE) targets. Simulation results show that this method can alleviate land use pressure and competition with food production caused by biomass-based NE technologies, while achieving net CO2 extraction.

Summary: A novel grey model is proposed in this paper, which introduces an exponential parameter to regulate the weight of information for studying carbon dioxide emissions of BRICS countries. The results show trends in CO2 emissions for each country and can be used as reference for relevant authorities.

Summary: This study investigated the impact of background CO2 concentration and indoor temperature on the rate of CO2 emission. Results indicated a higher CO2 emission rate at higher temperature levels and a lower emission rate with increased background CO2 concentrations. Further physiological measurements are needed to fully explain these findings.

Summary: Urban areas present key opportunities for mitigating emissions through supporting renewable energy systems, improving urban planning, and increasing resource efficiency. This research develops different emissions scenarios for urban areas and finds that it is possible to reduce annual urban emissions by 58.72 MtCO2eq in 2030 through a 100% renewable energy pathway.

Summary: Many companies' emission reduction targets may lead to temperature overshoot without explicit commitment to using negative emissions technologies in the long term. A proposed alternative approach suggests deriving corporate targets directly from the global remaining cumulative carbon budget to ensure consistency with long-term temperature goals. This study underlines the importance of a more precautionary and robust approach to corporate target setting.

Summary: In the context of the national 'dual carbon' strategy, expediting the green and low-carbon transformation has become a focal point across various industries. The challenge of reducing carbon dioxide (CO2) emissions in the transportation sector is exceptionally formidable, given its heavy reliance on energy. This article aims to identify an attainable, comprehensive pathway towards achieving net-zero emissions within the industry.

Summary: The study found that under severe drought conditions, denitrification pathways dominated N2O emissions in managed grasslands. Despite high variability in fluxes, denitrification continued to be the main emission pathway during rewetting, indicating feedback between precipitation changes and N2O emission pathways.

Summary: Integrated Assessment Models (IAMs) often underestimate global land-use fluxes compared to countries' GHG inventories, with a mismatch of about 5.5 GtCO(2) yr(-1). By adjusting IAMs' land-use mitigation pathways using a 'Rosetta stone' method, cumulative emissions can be reduced by 120-192 GtCO(2) relative to original pathways. These adjustments are crucial for ensuring an accurate assessment of progress towards the Paris Agreement.
