We examine the meanings of the packaging functions for consumers based on the data collected through an online consumer panel in Finland. The findings show that while the containment function of packaging plays the most important role for the consumer in general, the informative function is particularly relevant from the viewpoint of sustainability. Moreover, we identified two novel functions consumers highly appreciate –usability and disposability – that are largely irrelevant from the industry perspective.

In addition, the UHI vulnerability indicators are aligned with the three pillars of sustainability: social equity, economic viability, and environmental protection.

Under the sensitivity component, the indicators related to built environment, green spaces, and water bodies exhibit high to very high UHI sensitivity indicator scores. Under the adaptive capacity component, the indicators associated with government policy and action, multi-agency collaboration, and access to climate control appliances require corrective action. The metropolis- and administrative district-level UHI vulnerability indexes identify the extent and magnitude of UHI vulnerability of different urban areas, with high exposure and high sensitivity indexes and low adaptive capacity indexes contributing to high UHI vulnerability.

Studies focus on global and national impacts, marginalising the role and preferences of individual consumers. Diet is highly personal and for changes to be widely adopted they should be consistent with peoples' lifestyles, preferences, tastes, and knowledge. We construct global scenarios of reducing meat consumption and model their carbon mitigation potential to 2050. We conduct a simple survey to explore UK consumers' preferences for different approaches to reducing meat consumption, which are used to develop scenarios, and units for communicating the associated portion sizes and emissions savings. Results from our survey suggest that modest reductions in meat consumption are more resonant (e.g., eating three portions per week) rather than absolutes (becoming vegan for one month) or abstractions (consuming 170 cal of meat per day). Similarly, tangible analogies such as number of airline flights are preferred over raw emissions abated. We find that reducing meat intake to recommended healthy levels (92 cal per day) and avoiding ruminant meat could almost halve production-phase GHG emissions from the food system. Our survey illustrates how such information can be rephrased for more engaging communication: <em>“reducing your meat intake to three times per week is equivalent to avoiding six short-haul return flights each year”</em>.</p></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":"7 ","pages":"Article 100249"},"PeriodicalIF":4.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666049024000094/pdfft?md5=5a1a1e6d67ec407582dc553057e93da8&pid=1-s2.0-S2666049024000094-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140188114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The European Supervisory Authorities identify greenwashing risks and pronounce the limited ability of retail investors to make informed investment decisions. The aim of this perspective article is to provide suggestions for a regulation on relevant information on sustainable investments provided by financial service providers to retail investors. Therefore, the existing regulations are put in relation with recent research on investments considering ESG issues. To enable retail investors' self-determined decision-making, financial service providers such as banks, mutual funds, and financial advisors must provide easily accessible, clear, and easily understandable information regarding the ESG-conformity of the offered financial products.

Notably, the production of building materials and the construction phase contribute to the highest percentage (60.29%) of the total life cycle emissions owing to 49.51% of energy use. In contrast, emissions during the operational phase are relatively lower, attributed to increased electricity usage for cooking and minimal energy consumption for heating and cooling.

Investigating the long-term effects of biochar in increasing crop yields is crucial for food security and sustainable agricultural development. To address this issue, this study performed a coupling of meta-analysis and structural equation model (SEM) based on the establishment of a dataset containing 981 sets of observations. The results demonstrated that biochar significantly and durably boosted crop yield, and biochar also has shown an average increase of 36.2% in SOC over a monitoring period exceeding 2 years. Crop yields increased by an average of 16% after biochar application for the long-term scale, although the increase varied across crop types, and biochar application performed better on corn and wheat than paddy rice production. It is noteworthy that the yield still increased by 15% on average after 6 years of biochar application. According to SEM, the yield increase was positively correlated with the application amount of biochar, and the yield increase was higher under low nitrogen (N) input than under high N input. The long-term yield-increasing effect of biochar was more attributable to its enhancement of SOC rather than its effects on soil bulk density and pH.</p></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":"7 ","pages":"Article 100247"},"PeriodicalIF":4.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666049024000070/pdfft?md5=837b21e93b2bbb7e6d674e219fd513e9&pid=1-s2.0-S2666049024000070-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140052282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
