This study uses the GTAP-E-Power model to examine economic and environmental implications of transitioning different energy generation mixes in Vietnam by 2030. Three scenarios were considered for that year: (1) low-coal high-gas, (2) high-renewables, (3) high-coal. Scenario 2 emerges as most balanced approach, resulting a 1.02% GDP decline 0.78% increase CO2 emissions. In this scenario, electronics sector grows slightly (+0.3%), while metals (-3.1%) chemical products (-1.0%) experience moderate declines. terms exports, gives rise an trade balance (151 million USD) modest gain exports China (+0.46%), Japan (+0.37%), Korea (+0.33%), Western Europe (+0.35%). Across all three scenarios, output industry shows sensitivity mix changes, coal mining seems be resilient changing mix.

Approaches and perspectives on the transition to the circular economy in the European Union

Frontiers in Environmental Science, Год журнала: 2025, Номер 13

Опубликована: Март 4, 2025

Introduction The transition to a circular economy is key pillar of European sustainable development. However, in the current context, shaped by multiple crises and geopolitical conflicts, efficiency resilience this are particular concern. policymakers national authorities must adapt their approaches mitigate risks posed external factors while ensuring progress towards sustainability goals. This study analyzes from 2010 2022, assessing economic environmental variables. Methods employs an econometric approach using panel data 27 EU Member States. A linear regression model with fixed effects applied alongside spectral analysis descriptive statistics examine relationships between private investment, gross value added, municipal waste recycling rates, recyclable material flows, greenhouse gas emissions. These methods allow for in-depth evaluation influencing transition. Results Findings indicate that investment integration materials significantly enhance economy. varies across States due regional disparities, inadequate infrastructure, inefficient management. High-emission countries face greater challenges achieving targets, demonstrating need tailored resilient policy measures. Discussion results highlight necessity public policies promote attractiveness sectors, reduce improve management infrastructure. Additionally, emphasizes importance coordinated region-specific accelerate By integrating seasonal analyses, research contributes literature offering nuanced understanding affecting progress. insights valuable supranational developing effective strategies at level.

AI-Driven Circular Economy of Enhancing Sustainability and Efficiency in Industrial Operations

Sustainability, Год журнала: 2024, Номер 16(23), С. 10358 - 10358

Опубликована: Ноя. 27, 2024

This study investigates integrating circular economy principles—such as closed-loop systems and economic decoupling—into industrial sectors, including refining, clean energy, electric vehicles. The primary objective is to quantify the impact of practices on resource efficiency environmental sustainability. A mixed-methods approach combines qualitative case studies with quantitative modelling using Brazilian Land-Use Model for Energy Scenarios (BLUES) Autoregressive Integrated Moving Average (ARIMA). These models project long-term trends in emissions reduction optimization. Significant findings include a 20–25% waste production an improvement recycling from 50% 83% over decade. Predictive demonstrated high accuracy, less than 5% deviation actual performance metrics, supported by error metrics such Mean Absolute Percentage Error (MAPE) Root Square (RMSE). Statistical validations confirm reliability these forecasts. highlights potential reduce reliance virgin materials lower carbon while emphasizing critical role policy support technological innovation. integrated offers actionable insights industries seeking sustainable growth, providing robust framework future management applications.
