Energy poverty occurs when a household cannot fulfill its energy needs. Despite its widespread occurrence, Chinese cities have yet to formally recognize energy poverty as distinct from general poverty at the national level, thereby limiting the effectiveness of countermeasures. Guangzhou, a subtropical first-tier city in China, has a complex population comprising diverse migrants and locals of all ages. This age diversity greatly affects energy demand and poverty sensitivity, so analyzing age's impact on energy poverty is crucial. Thus, this paper surveyed 1072 households in 2020 to measure the extent of energy poverty. The energy poverty rate was found to be 13.85 %. Additionally, a U-shaped relationship was discovered between age and energy poverty, with a turning point at age 44. The adults in Guangzhou who are in energy poverty are not in income poverty. Higher education levels were found to impact energy consumption in households of both younger and older adults. For individuals older than 42—or 46 with a higher education level—the likelihood of experiencing energy poverty gradually decreases with age. Our findings indicate a unique pattern in which both younger and older individuals are susceptible to energy poverty in a humid subtropical climate. To achieve the UN's 2030 clean energy goals, policymakers must focus on tailored skill training, enhanced social welfare, and effective affordable housing policies to alleviate energy poverty. • We use survey datato measure Guangzhou household energy poverty. The LIHC indicator is 13.86%. • The relationship between age and energy poverty in the household is U-shaped. • Younger and older residents are vulnerable to energy poverty. • Younger and older highly educated individuals are more vulnerable to energy poverty than those without higher education.

Strew pellet production not only contribute to regional sustainable development and localized energy transition, but also help to mitigate global greenhouse gas emissions. With the development strew pellet products in China, it is critical to uncover the embodied emissions, land use and economic cost effectiveness from producing strew pellet. In order to reach such a target, two main categories of biomass pellet production including a large-scale centralized factory and a small-scale distributed workshop are investigated. Compared with raw coal production, the unit co-benefits in terms of per gigajoule of straw pellets from centralized factory are 1687 kg CO 2 , 8.65 g SO 2 , 3.21 g NOx, and 3.897 g PM 10 , and 0.33 m2 land use, and those for straw pellets from centralized factory are 1352 kg CO 2 , 8.46 g SO 2 , 3.12 g NOx, and 4.22 g PM 10 , and 0.33 m2 land use. Cost-effectiveness for the two straw pellets production system were also uncovered so that the relevant interested agents such as decision makers, business investors or environmental researchers can see the potential economic performance from developing such kind biomass plants. We conclude that environmental performance of the straw pellets whether from centralized factor or decentralized workshop have attractive alternatives to coal production. Image 108297 • LCA-based co-benefits approach was applied to investigate biomass pellet production. • The analysis framework includes energy consumption, equipment and infrastructure. • Emission factors and land demand for producing one-unit products are presented. • Environmental performance of straw pellets has attractive alternatives to raw coal. • Electricity is an important factor affecting the performance of pellets production.

Considering the significance and importance of urban sustainability in China and China's history of rapid urbanisation and industrialisation, this paper aims to incorporate the investigation of climate change and air pollution in urban sustainability research in China through a driver-pressure-state-impact-response model. The model has 12 indices: population, enterprise, registered vehicles, energy consumption, emissions and concentrations of carbon dioxide and sulfur dioxide, land use change, annual temperature, tropical nights and reforestation were selected. It was used in the analysis of 14 cities in the Liaoning Province. The results show that the model is an effective tool for urban sustainability research, allowing for the investigation of interactions of climate change and air pollution and contributing to the body of knowledge by aiding generation of realistic and practical measures.

Based on household-level survey data collected from Qinghai Province of China, we estimated the greenhouse gas (GHG) and air pollutant emissions from spatial perspectives, including household energy consumption in pastoral, agropastoral, and agricultural zones. The findings suggest that the total annual GHG and pollutant emissions per capita in the area was 2296.32 kg per year. The highest amount of pollutants was emitted from the pastoral zones, followed by the agropastoral and agricultural zones. CO 2 is the primary GHG emitted by household energy consumption. Dung burning was the cause of the high PM 2.5 emissions in the pastoral areas, while the use of coal was the primary cause of GHG and pollutant emissions in the agropastoral and agricultural zones. • We used empirical data from rural households in Qinghai, China. • This paper indicates the reliance of local energy consumption on non-commercial energy. • We estimate greenhouse gas and pollutant emissions resulting from solid-fuel combustion. • We compare indoor pollutant emissions from pastoral, agropastoral, and agricultural zones spatially. • This paper provides policy recommendations for energy transition towards clean energy. Energy consumption in the household sector has become an important issue in China's energy consumption and an important unit of China's clean energy transformation. Currently, the potential air pollution, carbon emissions and health risks caused by energy consumption in many areas cannot be ignored, and refined and regionalized index-based research data necessary to support decision making are lacking.

Dung burning was the cause of the high PM 2.5 emissions in the pastoral areas, while the use of coal was the primary cause of GHG and pollutant emissions in the agropastoral and agricultural zones. These findings highlight the need to integrate household energy policies with rural development to enable a complete transition towards cleaner fuels. [ABSTRACT FROM AUTHOR]
