Assessing carbon greenhouse gas emissions from aquaculture in China based on aquaculture system types, species, environmental conditions and management practices

Aquaculture is one of the world's fastest-growing food production industries, but many of the small-hold operations are poorly evaluated for their climate impacts. CO2082 and CHu2084 fluxes from various aquaculture techniques in China have been reviewed in the literature. The best CHu2084 emission was recovered from mudflat, but there was no CO 2082 emissions at the time, according to the Aquaculture system. We estimated that aquaculture plants in China generated 181. 66 Tg CO [u2082-eq yru206bb9, offsetting 7% of the national terrestrial carbon sink, with the bulk of the emissions occurring in coastal provinces and along the main rivers in the southeastern quadrant.

Carbon Monitor Cities near-real-time daily estimates of CO 2 emissions from 1500 cities worldwide.

This survey seeks to extend and temporal resolution of city-level pollution inventories and includes estimates for both functional urban areas and urban administrative areas that are consistent with national and regional averages. Cities around the world include the first estimates for several cities in low-income countries, including the first estimates for many cities in low-income countries. City Streets is a near-real-time, city-level emission dataset that includes cities around the world.

The impact of shadow banking activities on carbon dioxide emissions: empirical evidence from China.

Following the 2008 financial crisis, shadow banking operations, informal and less regulated financial activities, have emerged as a key part of financial markets. In previous studies, however, the impact of shadow banking activities on carbon dioxide pollution has been overlooked. The effect of shadow banking activities on carbon dioxide emissions in this paper is based on the panel annual reports of 30 Chinese provinces over the period 2013-2020. According to Heterogeneity's report, the impact of shadow banking activities on carbon dioxide is more pronounced for the secondary industry, indicating that shadow banking activities benefit more environmentally friendly firms. In addition, we investigate the causal consequences of shadow banking surveillance policy on carbon dioxide reduction by using the difference-in-difference method, showing that the shadow banking policy can reduce carbon dioxide pollution reduction by using difference-in-difference.

Spatial and temporal distribution characteristics of carbon emissions and their drivers in shrinking cities in China: Empirical evidence based on the NPP/VIIRS nighttime lighting index.

Shrinking cities are a group of cities characterized by population decline, and their environmental issues are often ignored. This paper examines the spatial and temporal distribution of carbon dioxide in shrinking cities in China and the driving causes using panel data from 2012 to 2019. According to the data, carbon emissions in shrinking cities have risen from 2012 to 2019, and in non-shrinking cities have decreased. Cities in Northeast China have higher carbon pollution levels than other regions due to earlier industrial growth and ecological neglect. The effect of living conditions on carbon pollution in shrinking towns is not significant. This paper outlines the driving factors of carbon pollution in shrinking cities in China, and, as a result, the findings of this paper provide valuable reference value for the formulation of carbon reduction plans in shrinking cities in developing countries.

Land use change and carbon emissions of a transformation to timber cities.

Using an open-source land system model, we investigate the global and regional impacts of increased demand for engineered wood on land use and associated CO 2 emissions until 2100. If 90% of the new urban population be housed in newly built urban mid-rise buildings with wooden constructions by 2100, we estimate that 106 Gt of additional CO 2 could be saved by 2100. Forest plantations will grow by up to 149 Mha by 2100, and harvests from unprotected natural forests will increase.

Effects of urban land intensive use on carbon emissions in China: spatial interaction and multi-mediating effect perspective.

Land intensive use is crucial for sustainable land use, however carbon capture is a barrier to achieve carbon freeness; they are closely linked and committed to sustainable socioeconomic growth, which is tied to sustainable socioeconomic growth. This paper incorporates the spatial Durbin model and mediating effect model to explore the consequences of urban land intensive use of carbon dioxide in 30 provinces in China between 1995 and 2018. The new ULIU's observed values are less than the inflection point of the curve, which means that the ULIU's improvement will result in more CEs.

Effect of environmental regulation policy synergy on carbon emissions in China under consideration of the mediating role of industrial structure.

For the design and decision-making of the other policy combinations, a comprehensive knowledge of the effect of environmental regulation policy synergy on carbon pollution is crucial. The effect of environmental legislation synergy on carbon reduction at low quintiles, i. e. , has an inverted U-shape trend, and after the turning point, it shows an "green paradox" effect, with a "green paradox" result, and after the turning point, it shows an 'emission reduction" effect.

Organic matter contributions to nitrous oxide emissions following nitrate addition are not proportional to substrate-induced soil carbon priming.

The addition of carbon substrate often reduces the rate of soil organic matter decomposition. Nitrous oxide emissions from soil have also been attributed to C substrate dynamics, although the relationship between the priming cause and soil N2O emissions is not clear. This research was designed to investigate the effects of C and N substrate addition on the linkages between SOM priming and N2 O emissions. Both CO 2 - and SOM-derived N 2 O emissions from soils with added glucose were higher than those from soils treated with acetate or butyrate, respectively, but carbon substrate addition increased both CO 2 - and SOM-derived N 2 O emissions in the presence of exogenous N 2 O emissions. There was no consistent correlation between the priming effect and SOM-derived N 2 O emissions. Priming in relation to soil N2O emissions needs to be investigated further.

Monitoring spatiotemporal characteristics of land-use carbon emissions and their driving mechanisms in the Yellow River Delta: A grid-scale analysis.

A comprehensive and accurate understanding of land-use carbon dioxide pollution level and its driving mechanism is critical to China's pursuit of low-carbon development, and it is also the scientific backbone for the development and implementation of regional carbon pollution policies. u2460 The total number of LCE in the study area increased from 2000 to 2019, but the growth rate slowed, but the peak of LCE hadn't been reached yet. The H-H aggregation region had a relatively stable spatial distribution area; the L-L aggregation area had wide distribution patterns that extended the entire study region; and the aggregation regions of H-L and L-H, which have yet to reach the scale.

Mapping carbon emissions of China's domestic air passenger transport: From individual cities to intercity networks.

The air transport sector plays a vital role in China's decarbonisation efforts as a key carbon emission source with high growth prospects. However, the spatial pattern and evolutionary dynamics of aviation carbon pollution in China have yet to be investigated thoroughly. The novelty of the study lies in the subtraction of carbon dioxide pollution of air passenger transportation in China's cities and intercity lines, which helps to reveal the spatial characteristics of individual cities in the intercity network, using data from 2019 to establish the aviation carbon emissions network. According to Corcorcor's study, a city's carbon emissions are highly linked to its demographic and economic characteristics, as well as its proximity to other cities, although a city's carbon footprint can be influenced by its centrality in the entire network and the community to which it belongs.
