The energy transition for the industrial sector is not limited to a reduction in energy consumption: the real issue is to combine sustainability with growth, by mixing the two ingredients (the rational energy use and the industrial growth) which are not always compatible. The National Energy and Climate Plan (NECP) and the New Green Deal policies in Italy have the goal to promote an economic development as well as the environment sustainability and social inclusion. RSE 1 has investigated the role of the national incentive plan 'Impresa 4.0' in Italy (currently 'Transizione 4.0', equivalent to 'Industry 4.0') as a measure to promote the energy transition, analysing whether and how is it possible to combine economic development with energy efficiency. Originally, it was developed to increase the competitiveness of industrial sector, but, progressively, it was also used to promote energy efficiency and sustainability. A survey was carried out by RSE on about 300 companies that implemented innovation and digitalisation interventions, monitoring the effects and impacts that the '4.0 choice' has determined on energy consumption, on their environmental externalities and, in general, on other costs. Moreover, some case studies were collected, together with a database of 'Impresa 4.0' application, which supported technical and economic evaluations. The impact of these measures on energy performance of the companies was estimated from the analysis of actual projects and from interviews and discussions with the operators. In this paper, the results of the survey are presented and the outcomes are analysed in comparison with the Italian manufacturing sector performance, in order to establish the potential of 'Impresa 4.0' policies in supporting the decarbonisation process and reaching 2030 environmental targets.

Since the introduction of the International Pollution Prevention and Control (IPPC) directive and of the Best Available Techniques Reference (BREF) documents, the best available techniques (BATs) have become a reference both for policies and for companies to compare performance and to identify investment opportunities. Due to the environmental core of the IPPC and the Industrial Emissions Directive (IED), energy efficiency (EE) BATs are not always detailed and often lack energy-performance indicators. The H2020 EU-MERCI project is aimed at fostering and facilitating the implementation of EE projects in the manufacturing industry sectors by selecting and disseminating technological and policy best practices. A set of EE 'Good Practices' (GPs) was developed considering both BREF indications and literature analysis, and as innovative approach the outcomes of EE obligation and support measures aimed at the industrial sector. This was implemented through an in-depth analysis of the existing schemes in four countries (Austria, Italy, Poland and UK) and a thorough activity to normalise and compare the data made available by the different schemes. The outcome is available through the European Industrial Energy Efficiency good Practices platform implemented by EU-MERCI Partners. On the platform, a database of EE projects implemented in industry under the existing schemes is available. The database is searchable by country, sector, supporting scheme, implementation year and company size. The complete list is also downloadable as Excel file. Besides, a library divided by sectors is available, in which it is possible to look for the available GPs (both BATs and projects implemented under the national schemes) for each phase of the manufacturing processes. Sectoral and national analyses are finally available. This article will illustrate the methodology used for the project and the main outcomes.

In the near future, cities will have to supply innovative and high value-added mobility services, that shall be sustainable in terms of environmental impact, traffic management and energy efficiency. This represents a great challenge: transportation accounts for 20% of the global energy consumption, with a large share in urban areas (around 40% of total transport consumption). One of the most promising solutions to reduce congestion, energy consumption and air pollutants in highly-populated areas is Ride Sharing. Ride Sharing systems aim to bring together travellers with similar itineraries and time schedules, thus providing significant societal and environmental benefits, such as reducing the number of cars used for personal travel and improving the utilization of available seat capacity (also defined "occupancy rate"). This paper examines the impact of Ride Sharing by developing an enhanced transport model in Visum, which takes into account the shareability of passengers mobility patterns. The model is applied to the Milan Metropolitan Area, which represents an interesting test case for two main reasons: first, its high population density and strong transport offer and second, the large amount of information and data available on passengers mobility. The paper assumes an optimal 20% participation rate to Ride Sharing and estimates its benefits in terms of congestion reduction, energy efficiency and environmental impact. The COPERT software is used to estimate Carbon Dioxide emissions and fuel consumption savings. The simulation results show that Ride Sharing brings a sort of rebound effect, since there is an increase in passengers traveling by car. However, the overall effect is a reduction in the number of vehicles used, with consequent reductions in vehicle kilometers travelled (-3,8%). This translates into 6% energy savings and 6% Carbon Dioxide emissions reduction. Some policy recommendations are provided to develop Ride Sharing in order to increase the effectiveness of this system while restraining side effects.

With the publication of the Energy Efficiency Directive (EED) in 2012, energy savings in the Industry processes have gained more and more importance in the European Union (EU). Industry (with building and transport) is one of the three main sectors where Energy consumption and efficiency play a fundamental role, to accomplish the EU energy objectives. Many countries in EU have already adopted schemes and mechanisms to implement the Directive: however deep differences of approaches still remain among the Member States (MSs), especially with respect to the identification of the real benefits of measures and to the assessment of their efficiency and sustainability. As a consequence, a huge amount of the efficiency potential still remains untapped. This paper proposes some criteria for the evaluation of the applied Energy Efficiency measures, leading to the identification of Good Practices of Energy Efficiency. These criteria are taken from the 'real world' of industry, and are susceptible to be replicated in other contexts (e.g. different sectors or other countries). The proposed criteria have been developed in the EU H2020 project EU MERCI (nr 693845) and through a national research (part of the 'Ricerca di Sistema' national funding system) both coordinated by RSE. The starting point is the harmonization of data sets related to projects developed in different EU countries within local efficiency implementation schemes. The second step is the definition of Key Performance Indicators (KPIs) reflecting the impact of measures against Energy, Environment and Economic aspects. The last step is the extraction of efficiency 'Good Practices' ranked according to the identified KPIs and other factors, including social elements. The real added value of this approach is that it is full based on tangibly implemented projects, in opposition to similar attempts, essentially theoretical. Ultimately, it offers a key of assessment of the effectiveness of efficiency measures implementing local and EU policies.
