Energy efficiency is crucial to the 2030 UN Sustainable Development Goals (SDGs), but its widely measured indicator, energy intensity, is still insufficient. For this reason, in 2006, total factor energy efficiency (TFEE) was proposed with capital, labor, and energy as inputs and GDP as the desirable output. The later TFEE approach further incorporated pollution as the undesirable output. However, it is problematic to regard GDP (the total value of final products) as the desirable output, because GDP does not include the intermediate consumption, which accounts for a large part of the production activities and may even be larger than the value of GDP. GDP is more suitable for measuring distribution, while VO (value of output) is more appropriate for sustainable production analysis. Therefore, we propose a VO TFEE approach that takes VO as the desirable output instead and correspondingly incorporates the other intermediate materials and services except energy into inputs. Finally, the empirical analysis of the textile industry of EU member states during 2011–2017 indicates that the VO TFEE approach is more stable and convergent in measuring energy efficiency, and is more suitable for helping policymakers achieve the SDGs of energy saving, emissions reduction, and sustainable economic development.

Evidence-based policymaking must be rooted in sound data to inform policy priorities, budget allocations, and tracking of progress. This is especially true in the case of the Sustainable Development Goals (SDGs), as they provide the policy framework that all 193 UN member states have pledged to achieve by 2030. Good data and clear metrics are critical for each country to take stock of where it stands, devise pathways for achieving the goals, and track progress. Current assessments of the EU’s performance on the SDGs, however, tend to reach different findings and policy conclusions on where the priorities for further action lie, which can be confusing for researchers and policymakers. In order to demystify the drivers of such differences and make them transparent, this paper compares and contrasts the results obtained by four SDG monitoring approaches. We identify three main elements that are responsible for most of the differences: (i) the use of pre-defined targets for calculating baseline assessments and countries’ trajectories; (ii) the inclusion of measures that track not only domestic performance, but also the EU’s transboundary impacts on the rest of the world; and (iii) the use of non-official statistics to bridge data gaps, especially for biodiversity goals. This paper concludes that there is not one “correct” way of providing an assessment of whether the EU and EU member states are on track to achieve the goals, but we illustrate how the different results are the outcomes of certain methodological choices. More “forward-looking” policy trackers are needed to assess implementation efforts on key SDG transformations.

We live in complex times in the health, social, political, and energy spheres, and we must be aware of and implement new trends in intelligent social health systems powered by the Internet of Things (IoT). Sustainable development, energy efficiency, and public health are interrelated parameters that can transform a system or an environment for the benefit of people and the planet. The integration of sensors and smart devices should promote energy efficiency and ensure that sustainable development goals are met. This work is carried out according to a mixed approach, with a literature review and an analysis of the impact of the Sustainable Development Goals on the applications of the Internet of Things and smart systems. In the analysis of results, the following questions are answered about these systems and applications: (a) Are IoT applications key to the improvement of people’s health and the environment? (b) Are there research and case studies implemented in cities or territories that demonstrate the effectiveness of IoT applications and their benefits to public health? (c) What sustainable development indicators and objectives can be assessed in the applications and projects analyzed?

The 21st century brings countless social, economic, environmental, and technological challenges to humanity and, to face them, the United Nations (UN) created the Sustainable Development Goals (SDGs). The auto industry, which is part of the private sector, aims to reach them. In this context, this study aims to evaluate the consumption and emissions of pollutants by using an automatic transmission of the CVT (Continuously Variable Transmission) type concerning the automatic transmission of the "Planetary" type. This study will be based on the Consumption/Energy Efficiency tables, published annually by INMETRO (National Institute of Metrology, Quality, and Technology) and whose data will be processed and evaluated using the Quik Sense Software. Thus, the work aims to appraise the advantages of vehicles with automatic transmission of the CVT type about fuel consumption, energy efficiency and emissions, in markets such as Brazil, where these vehicles use ethanol or a mixture of gasoline with up to 27 as fuel % Ethanol. This research can contribute to studies of emission control and approval, benefiting the automotive industry in general, government agencies, the environment, the economy, and society, contributing to the UN's SDGs achievement.

The European energy policy is a core role in the development of the new model of the energy market and carbon-free economy in Ukraine. In the paper, the authors analyzed the key issues on the way to implement the European policy on increasing energy efficiency and green innovations which emphasized in pro et contra. The performance of national energy policy could be limited by the market instruments, the efficiency of the smart grid and perception of innovations in the energy sectors, institutional development in general. Thus, the paper aimed to indicate the impact of green innovations on sustainable development and the country’s energy efficiency for 2000-2019. The authors used economic and mathematical modeling. The Ordinary Least Square Model was used for the integral assessment of energy efficiency policy. The authors analyzed nine sub-indicators from four Sustainable development goals (Affordable and Clean Energy, Decent Work and Economic Growth, Responsible Consumption and Production, Combating Climate Change) and the indicator which characterized the innovation costs of industrial enterprises in the energy sector in Ukraine. The methodological instrument for checking the hypothesis and empirical justification was software stats models в Python 3.6.11. Due to the seven rounds of optimization, the authors developed significant functioning. Considering the finding of Ordinary Least Square Modelling, the authors highlighted the determinants which influenced the efficiency of energy policy: dependence on energy imports by-products, real GDP per capita, and final energy consumption. At the same time, the final energy consumption had less effect on the efficiency of energy policy and demonstrated the negative relationships with energy efficiency. The results of the models were verified using RESET and Jarque-Bera tests and confirmed the correctness of the proposed model. Keywords: energy policy, sustainable development goals, green innovations, energy efficiency.
