Production and carbon emission abatement decisions under different carbon policies: supply chain network equilibrium models with consumers’ low‐carbon awareness

We investigate and compare their equilibrium decision conditions under three common carbon policies: carbon cap, carbon cap, and carbon levy, among others. However, an appropriate carbon cap size will not only encourage manufacturers to minimize carbon dioxide pollution but also raise their profits. The effectiveness of a carbon cap u2010trade scheme is similar to that of a carbon cap policy, but it has greater flexibility.

Effect of straw biochar application on soil carbon, greenhouse gas emissions and nitrogen leaching: A vegetable crop rotation field experiment

We undertook a field trial to determine the effects of biochar application on these variables in a lettuce, water spinach, and ice plant rotation. By 1. 5 percent and 12. 4 percent, respectively, during the lettuce and water spinach seasons, respectively, with the lowest N2O emissions due to the 20 t hau20101 application rate leading in the lowest N2O emissions during the lettuce and water spinach seasons. Following a 7. 3 percent decrease in dissolved nitrogen content in the soil, Biochar also reduced the dissolved nitrogen content in leachate by 9. 8 percent. U201336. 2%. Following a 3. 8 percent decline in the soil nitrate level in leachate, biochar reduced the nitrate concentrations by 3. 9 percent, reducing by 3. 2 percent.

Does duration of team governance decrease corporate carbon emission intensity

The research explores the effect of team longevity on carbon emission intensity of 608 U. S. listed companies' carbon dioxide levels over the period 2009-2013 using unbalanced panel data analysis. The results reveal an inverted Uu2010-shaped relationship between DTG and carbon emission intensity. Carbon dioxide pollution intensity increased when the period is less than 6. 52 years, but it exceeds 6. 52 years, as carbon dioxide pollution intensity decreased. The study reveals that the low-u2010carbon innovation, rather than DTG, is a good mediator for DTG to reduce carbon emission intensity.

Investigation of bending performance of printed continuous carbon fiber reinforced polylactic acid using acoustic emission

The effects of deposited space and layer thickness on bend results are investigated, and failure modes are determined accordingly. In a range of layer heights of 0. 7, 0. 8, and 0. 9 mm, the bending strength and modulus of the printed composites decreased in parallel with layer thickness rises. When the fused deposited space is between 0. 6 and 0. 8 mm, the bending strength and modulus decrease correspondingly as the increase in the deposited space. The test signal could be represented by three key elements, and by using kmeans++ cluster algorithm analysis, the three key elements can be divided into five clusters, which correspond to the material failure mode of matrix cracking, interlayer delamination, fiber, and fiber cracking, fiber cracking, and fiber cracking. As a result, the bending failure process can be properly investigated in detail with the clustering results.

Cropland intensification mediates the radiative balance of greenhouse gas emissions and soil carbon sequestration in maize systems of sub‐Saharan Africa

Here, we're based on 2 years of field investigation of soil variations in SSA, providing the first, complete account of GWP for maize systems in reaction to cropland intensifications. To confirm our field findings on SOC change, we developed a process-u2010oriented model parameterized with field data to simulate SOC dynamics as time progress. Overall, we find encouraging results that combine residue and fertilizer delivery resulted in sequestering 82 million kilograms of CO2 per Mg of maize grain grown across two soils, as shown by the following table. All reports pointed to a success of sandy soils over clay soils in meeting increased SOC sequestration goals, and prompted a re-u2010evaluation of sandy soils in SSA croplands.

Effect of experimental exposures to 3‐D printer emissions on nasal allergen responses and lung diffusing capacity for inhaled carbon monoxide/nitric oxide in subjects with seasonal allergic rhinitis

28 young people with seasonal allergic rhinitis were exposed to 3u2010D printer emissions, either from polylactic acid or from acrylonitrile butadiene copolymer, each, for 2 h each, using a cross-over scheme. The exposures resulted in marginally reduced lung diffusing capacity for inhaled nitric oxide, which were similar to PLA and ABS. After ABS exposure versus inclusion day, In nasal secretions, concentrations of interleukin 6 and tumor necrosis factor were marginally reduced, while the percentage of interleukin 5 was marginally increased after PLA exposure versus inclusion.

Contextualizing embodied carbon emissions of concrete using mixture design parameters and performance metrics

Multiple organizations have called for reducing the tangible carbon associated with concrete production. The findings show that the cement content is the most reliable predictor of global warming potential, and that significant GWP savings can be achieved by lowering and replacing cement without compromiseing results. Clear correlations of GWP with compressive strength were not established, but the findings showed that reduced GWP and increased electrically based resistivity were common in synergy, which were not discovered.

Impact assessment and mechanism of water conservancy policy on carbon emission performance under the background of artificial intelligence

With the growing body of carbon pollution, the study into the introduction of water conservancy measures in carbon dioxide has progressed, and its operational implications are of utmost importance in addressing the challenge of raising carbon dioxide efficiency. With the in-depth study on carbon pollution, the issue of raising carbon dioxide efficiency has gradually evolved. This paper has been designed to investigate the effects and mechanism of water conservancy policies on carbon reduction progress in the context of artificial intelligence. Through the analysis and review of the water conservancy policy under artificial intelligence, the double difference model is used to evaluate it in order to determine the effect and mechanism on carbon pollution results, so as to solve the issue of increasing carbon emission results. The results have shown that water conservancy policy has a significant and persistent driving effect on carbon emission reduction, and that its interaction coefficient under the control variable is u22120. 934, which is significantly negative.

Digital economy, new‐type urbanization, and carbon emissions: Evidence from China

China has been a major carbon dioxide emitter. According to the World Energy Statistics Yearbook 2021, China's total carbon emissions in 2020 reached 9. 899 billion tonnes, accounting for 30. 7% of the world's total emissions and ranked first in the world. This article empirically investigates the consequences of digital economy and urbanization of neo-u2010type urbanization on carbon pollution in 30 provinces of China based on the decoupling scheme and threshold regression model. The results show that 23 provinces of China have a stronger decoupling relationship between digital economy and carbon reduction, with 20 provinces of China having a stronger decoupling relationship between new-u2010type urbanization and carbon emission reduction, and 20 provinces of China have a better decoupling relationship between new urbanization and carbon reduction than those of carbon dioxide reduction. With energy intensity as the threshold variable, the threshold regression models have a significant threshold characteristic, with a negative non-u2010linear effect on per capita carbon emissions.
