To avoid these windfall profits and to decrease leakage, two major modifications have been implemented for the third phase: electric companies no longer receive free allowances, while energy intensive and trade exposed sectors are granted free allowances that are calculated based on firm production capacity. This paper theoretically shows a new type of profit increase in sectors that are not exposed to international competition. This paper also illustrates the profit increase for the third phase of the EU-ETS and shows that profits in the electricity sector may increase by approximately 2% when free allowances are given to the other sectors.

In this work, we integrate the concepts of Industry 4.0, smart manufacturing, and sustainable manufacturing in a model that provides a conceptual framework for the study of long-term solutions with a high degree of specialization, according to the specific context of each investigation. This study offers a holistic analysis and evaluation of the main challenges facing the Industry 4.0 concept. We also diagnose the current methodological proposals aimed at solving the challenges of Industry 4.0 and sustainability using a systemic review of the literature from the past 5 years. Firstly, we identify 14 technological trends linked to Industry 4.0. Subsequently, the trends are integrated into the proposed model to identify opportunities, evaluating their relationship with three performance areas. This allows the identification of trends that present the greatest number of opportunities in the context of sustainability. The second stage complements the literature review with a descriptive analysis of the studies and discusses the findings. The study concludes that the identified technological trends positively impact Industry 4.0 challenges, helping to achieve sustainable manufacturing objectives.

This paper analyzes the implementation of pollution permits. It focuses on the distributional impacts linked with the stringency of output-based allocation when two sectors are covered by the market for permits and the total cap is held constant. A new type of profit increase in sectors that are not exposed to international competition, when energy-intensive trade-exposed (EITE) sectors are granted output-based allocations, is demonstrated theoretically. The paper also illustrates a profit increase in the electricity sector in a possible fourth phase of the European Union Emission Trading Scheme, in which output-based allocation will be granted to EITE sectors, compared with the case in which all permits are auctioned.
