The environmental impact of traded plastic waste hinges on how it is treated. Existing studies often use domestic or scenario-based recycling rates for imported plastic waste, which is problematic due to differences in recyclability and the fact that importers pay for it. We estimate the minimum required recycling rate (RRR) needed to break even financially by analysing import prices, recycling costs, and the value of recycled plastics across 22 leading importing countries and four plastic waste types during 2013–2022. Here we show that at least 63% of imported plastic waste must be recycled, surpassing the average domestic recycling rate of 23% by 40 percentage points. This discrepancy suggests that recycled plastics volumes from the global North-to-South trade may be underestimated. The country-specific RRR provided could enhance research and policy efforts to better quantify and mitigate the environmental impact of plastic waste trade.

This paper systematically analyzes the effect of energy efficiency on transacted rental and capital values of Dutch retail property assets from 2015–2021. Prior research on Energy Performance Certification (EPC) and energy premiums consistently showed a pricing effect, but recent investigations reveal inconclusive results, particularly when considering non-residential properties. Leveraging a unique dataset of 1015 lease transactions and 478 sale transactions, this study provides one of the first estimates of how EPC labels impact retail value. We utilize ordinary least squares (OLS) regression, considering characteristic retail determinants such as footfall, catchment area type, and retail type, among others. This study finds a premium of 11 percent for rental transactions with Label C or higher on a price per square meter basis. Capital premiums for energy-efficient transactions are more marginal and complex, particularly when accounting for data limitations such as geographic distribution. The nexus between sustainability and financial benefits incentivizes investors and policymakers to embrace energy-efficient measures. Pioneering spatial analyses of EPCs in the retail sector, this paper offers insights for informed policy-making amid geographic variations. In the era of transparency, this research provides empirical evidence to drive responsible investments in energy-efficient retail, shifting from risk management to stakeholder benefits and improved capital efficiency.@en

The global trade of plastic waste has raised environmental concerns, especially regarding pollution in waste-importing countries. However, the overall environmental contribution remains unclear due to uncertain treatment shares between handling plastic waste abroad and domestically. Here, we conduct a life cycle assessment of global plastic waste trade in 2022 across 18 countries and six plastic waste types, alongside three “nontrade” counterfactual scenarios. By considering the required cycling rate, which balances importers’ costs and recycling revenues, we find that the trade resulted in lower environmental impacts than treating domestically with the average treatment mix. The trade scenario alone reduced climate change impact by 2.85 million tonnes of CO₂ equivalent and mitigated damages to ecosystem quality, human health, and resource availability by 12 species-years, 6200 disability-adjusted life years (DALYs), and 1.4 billion United States dollars (USD in 2013), respectively. These results underscore the significance of recognizing plastic waste trade as a pivotal factor in regulating global secondary plastic production when formulating a global plastics treaty.
