“…The obtained results for the EU-27 are in line with other empirical papers. Thus, Guo et al (2022) [55] found that a 1% increase in renewable energy consumption led to a decrease in carbon emission balance of 5.8%. For G7 countries, it was proven that hydroelectric and renewable energy production was able to reduce CO 2 emissions in all regression models [56].…”

Recent trends prove that energy production is shifting from traditional fossil fuel combustion technologies to renewable energy-based technologies. To estimate the economic efficiency of renewable energy technology implementation, the data for the EU-27 member states during the 2012–2021 period were collected; additionally, technological efficiency was analyzed based on a critical literature review. Breusch and Pagan Lagrangian multiplier tests were employed to select the most suitable econometric model. The results suggest that an increase in the share of renewable energy sources by one percentage point (1) decreased CO2 emissions by 0.137 metric tons per capita (technological efficiency) and (2) decreased greenhouse gases by 13 g per EUR, in terms of GDP (economic efficiency). Regarding the Kyoto Protocol implementation, it was found for EU-27 that an increase in the share of renewable energy sources by one percentage point was related to a decrease of one percentage point in the greenhouse gases index. GDP per capita appeared to be an insignificant driver for reductions in per capita CO2 emissions, while it proved to be important for economic efficiency models. Thus, increasing GDP per capita by 1000 USD reduces greenhouse gases by 7.1 g per EUR of GDP in EU-27. This paper also confirmed that a unit of electricity (1 kWh) generated by traditional energy plants is seven to nineteen times more environmentally costly than renewable energy generation. This paper thus concludes that digital transformations and additive manufacturing brought about the significant dematerialization of industrial production and the promotion of renewable energy on industrial and household levels.

Everyday activity incurs carbon footprints, which are classified as personal, production, organizational and national, and may be assessed by input–output analysis (IOA), life-cycle assessment (LCA), or the combination of LCA and IOA methods. Notwithstanding international standards, like ISO 14064 and Publicly Available Specification (PAS) released for standardization, carbon footprint results can vary and sometimes lack consistency that due to variations in data sources, crossover boundary definitions, and operational boundaries for indirect emissions. The novelty of this study is the direct utilization of condensed water in an existing cooling water system, without the need for prior wastewater treatment, as typically required for greywater. The lack of practical case studies exploring the water–energy nexus in the context of reclaiming condensed water for evaporative cooling tower systems makes this research particularly significant. This highlights that condensed water can be a straightforward and cost-effective solution for both water conservation and energy savings. This case study highlights the benefits of reclaiming condensed water as supplementary cooling water, which proved effective in water quality treatment and dilution augmentation, considering that a higher cycle of concentration (CoC) was achieved, leading to reduced bleed-off that resulted in a water saving of 44% for make-up and 80% for bleed-off water, and energy savings from 6.9% to 13.1% per degree Celsius of condensing refrigerant temperature (CRT). The analytical assessment revealed that reclaiming condensed water is a promising answer for green building and is a by-product of condensation without extra power demands, avoiding the generation of an increased carbon footprint and exacerbation of greenhouse gas (GHG) emissions from freshwater resource extraction, and for the production of energy-efficient devices or substitutions. By eliminating the need for wastewater treatment, this research enhances the practicality and feasibility of direct use of condensed water in various applications. This approach not only promotes sustainability by conserving water and energy but also renews interest among proponents of green building practices. It has the potential to accelerate the adoption of this method and integrate it into green building designs.

A reduction in SO2 emissions is important for sustainable development. However, China uses territorial emissions to determine its SO2 emission mitigation targets, ignoring the emissions that are incorporated into interregional trade. In addition to the transfer of pollution, value added can also be exchanged with trade, resulting in environmental inequality among regions. In this study, we estimate the embodied SO2 emissions (ESE) under production-, consumption-, and income-based accounting principles and quantify the embodied value added (EVA) within the interprovincial trade during 2007–2017 using the multi-regional input–output (MRIO) model. The inequalities between the ESE and EVA are further investigated using the Gini coefficients method and the regional environmental index method. The results indicate that ~34.7–43.4% of SO2 emissions and ~24.6–30.8% of value added were triggered by interprovincial trade. Furthermore, developed provinces mainly outsourced their emissions to less developed provinces, particularly to those nearby. Concerning the value added, it was mainly outsourced from less developed provinces to developed provinces during 2007–2010, with no clear patterns observed during 2012–2017. The study’s findings indicate that the high inequality of SO2 emissions and value added also occurred between developed and less developed provinces. Particularly, the Gini coefficients of value inflow–SO2 outflow (VISO) were larger than those of value outflow–SO2 inflow (VOSI), which indicated that, besides the direct emissions, consumption-based emissions should be considered when allocating the environmental responsibility among provinces. These findings are valuable for shaping pathways towards achieving regional economic coordination and sustainable development.
