Abstract Based on the data of 57 cities in the Yellow River Basin (YRB) during 2006-2019, this study analyzes its spatio-temporal evolution of carbon dioxide (CO2) emissions from energy consumption, and decomposes its CO2 emissions changes into five factors. The results indicate that: (1) The CO2 emissions in the Yellow River Basin has increased but did not reach the peak from 2006 to 2019, which showed a spatial distribution pattern of “high in the east and low in the west”, with Baotou city, Taiyuan city, Xi’an City, Zhengzhou City and Zibo city forming several high CO2 emission centers of d

Abstract:
In Indonesia, transportation sector, specifically road transport consumed most energy compared to other sectors. Eventually, the energy consumption will increase due to the growth of vehicle number that also escalate emission. Vehicle emissions had been recognized as a significant contributor to atmospheric greenhouse gas (GHG) pollution. Heavy-duty vehicles are considered as main sources of vehicular emissions in most cities. Therefore, it is crucial to take into account heavy-duty vehicle emission projections in order to support policymakers to identify vehicle emissions and develop pollutio

Abstract:
China, the world’s top CO2 emitter, is faced with pressure of energy-saving emission reduction. In the 2015 Paris Climate Conference (COP21), China announced its plan, aiming to cut down CO2 emissions by 60%–65% per unit of GDP in comparison to 2005’s level by 2030. To achieve this ambitious goal, reliable national, provincial, and city-level statistics are fundamental for multi-scale mitigation policy-makings as well as for the allocation of responsibilities among different administrative units. However, China implemented a top-down energy statistical system. The National Bureau of Statistics

Abstract:
City size expansion in China creates substantial economic circulation, which impacts CO2 emissions. Since CO2 production primarily comes from human activities, CO2 emissions are mainly in cities. To achieve China’s carbon neutrality and provide specific implementation guidance for future carbon-reduction policies, it is worth assessing China’s pressure on carbon reduction in the urban aspect. Highly developed social productivity and a market economy lead to a dramatic increase in the interconnection between cities, and the spatial distribution of CO2 emissions emerges in a spatial association.

Land use has a very close relationship with transportation. Transportation is formed as a result of the interaction between land use and its support system. Good land use supported by good infrastructure will result in good movement as well.

The increase in population causes an effect on increasing CO2 production, especially from the household energy sector. The increase in the concentration of CO2 in the atmosphere is the main trigger for climate change and the effects of greenhouse gases. Indications of the occurrence of this phenomenon can be seen from the increase in air temperature and the formation of an urban heat island in Kendari City in the last 10 years. This study aims to determine the amount of CO₂ emissions from household activities and the absorption of CO2 gas from tree species in Pondambea Village, Kadia District,
