China is the largest paper producer and consumer in the world. However, China's paper industry is inefficient in its consumption of natural resources. Whereas the proportion of wood pulp used by the paper industry in developed countries is up to 63%, the corresponding figure for China is only 23%, leading to high energy and water consumption and severe environmental pollution. This article presents a systematic risk analysis using life cycle assessment and carbon footprint calculation associated with China's straw-pulp and wood-pulp paper industries. Risk prevention measures are proposed based on the results of this analysis. The study has important ramifications for the sustainable development of China's paper industry.

Controlling household consumption is an essential means to achieve carbon neutrality in China, and population ageing has an important impact on its structure. Since older people exhibit different consumption patterns than younger people, an increase in the proportion of aged people affects overall consumption patterns. This paper adopts an input–output model to reflect the heterogeneity in the consumption structure and household carbon footprint of different age groups, followed by a simulation of the future household carbon footprint. The results find that in China, the total household carbon footprint shows an inverted U-shape with age, with the lowest total carbon footprint coming from aged households (age of household head 65 and above) and the highest total carbon footprint from middle-aged households (age of household head 45–54). The average household carbon footprint decreases with age, with aged households remaining the lowest. Aged households, however, have the highest share of the direct carbon footprint. Interestingly, urban households of all ages have a higher carbon footprint than rural households, with the largest difference being among aged households. The projection results show that based on demographic changes, although the average household carbon footprint of elderly households in China is low, as the number of elderly households increases, the total carbon footprint of elderly households will be sizable and need to be taken seriously. The total carbon footprint of elderly households will become more significant and sizable as the number of elderly households increases. Urban life is more carbon-intensive, and China's urbanization is leading to an increase in the carbon footprint. Aged households require more attention in future climate policies. Targeted, consumption-based climate policies are necessary for carbon reduction in China and will have relevance in other countries with similar consumption structure and demographic trends, e.g. with ageing or rapidly urbanizing populations.

This study examines attitudes to tourism and climate change among residents of Hong Kong and evaluates their willingness to voluntarily modify travel behaviours to reduce environmental impacts. Previous studies on environmental behavioural change identified a significant gap between awareness and action, with some studies even suggesting that the most aware individuals are unlikely to change their behaviours. Similar findings were noted in this study. Cluster analysis identified four cohorts of tourists, ranging from the regular international tourist to the least travel active. The regular international tourist group was most aware of global warming and climate change, but least willing to alter its travel behaviour. By contrast, less travel active tourists seem most willing to travel less. The paper concludes that government intervention may be required to create meaningful behavioural change in travel patterns.
