Sustainability and sustainable development are objectives, but also values that must be respected in the field of public procurement. The main objective of this paper is to document the interest in the research area of green public procurement. The research methodology involves the elaboration of a bibliometric analysis (therefore a quantitative research method), in the form of an inventory of the publication activity in the aforementioned field. The analysis was developed by querying the existing database on the Scopus platform, which contains documentation on journals, scientific papers, books and others. The query determined the display of a number of 6,257 scientific documents existing in the database containing the acronym for Green Public Procurement in the title, summary or keywords. The query was conducted on September 25, 2019 and includes publications, regardless of the location or date of publication. The research results confirm the increase of the scientific interest in the field of green public procurement. Since 2010 until the moment of querying the Scopus database, 3,441 documents were identified related to this topic, which represents more than half of the total elaborated documents existing in the database on the same topic, indexed between 1959 and 2009.

The vegetable sector plays an important role in ensuring food security. Vegetable trade flows in Romania have become a major concern due to constant trade balance deficits despite the country’s agricultural potential. Taking into account the paradox between what could be considered an abundance of factor endowments and poor trade balance results, the objective of this research was to study the linkage between vegetable trade flows and chain competitiveness. Spatial panel econometric methods were used to study the impact of the international vegetable market on the demand in Romania, while the Balassa index and Porter’s diamond modelling techniques were used to study the competitiveness of the vegetable chain at both county and national levels. By applying the spatial regression method to the international trade and national production panel data, it was found that an increase in the quantity of vegetables imported into Romania would cause an even greater decrease in national vegetable production. The results show that Romanian vegetable production is highly and negatively influenced by the growing appetite for imports—therefore leading to a national dependence on the global vegetable chain. Porter’s diamond model results confirm that: (a) growing vegetables is profitable in Romania and the average profit margin is higher in this economic sector than in many others; (b) there is a lack of competitiveness caused by the post-communist excessively fragmented agrarian land structure and poor performance of the irrigation, warehousing, and transportation sectors; (c) the national production of vegetables is generally self-sufficient with the exception of three counties that resort to importing and account for more than 70% of Romania’s total vegetable imports; (d) factor endowments cannot be fully harnessed, and this contributes to the deepening of the trade balance deficits. Improvement is possible by fostering competitiveness through increasing the performance of supporting industries and the logistics infrastructure, as well as removing market access barriers for the many small farmers.

In this paper, we fill the gap in the literature by identifying a negative relationship between fuel ethanol consumption and CO2 emissions, building on a sample of 17 European countries covering seven years, from 2010 to 2016. Based on a Panel Smooth Transition Regression approach we show that countries with high levels of income inequality have difficulties in avoiding environmental degradation by promoting policies and regulations for more intense use of biofuels. Furthermore, we bring strong empirical evidence suggesting that biofuels could be an alternative in the future to reducing CO2 emissions. In our opinion, this non-linear analysis could provide the scientific basis for authorities, especially the European Commission to promote environmental policies to a specific country with different levels of carbon emissions rather than to the entire group.

This paper focuses on the current environmental issues, more specifically the amount of greenhouse gases humanity is being confronted with at the moment. The research was carried out on a niche of the topic, namely on the carbon footprint of public buildings. The concept of a sustainable university is new and insufficiently explored, and as part of the environmental metabolism, it influences anthropic sustainability in a directly proportional manner. This indicator’s monitoring systems reveal how vulnerable humanity is in front of the latency of an unprecedented and inevitable environmental catastrophe. The ecological effects may be mitigated by the academic community through green urban design. The ecological performance can be expressed in an economically efficient manner, which can, at the same time, create a precious channel of communication within the entire academic community though volunteering for sustainability. Moreover, this research has identified several solutions for optimizing the carbon footprint, which do not hinder the necessary economic development. Within the current context, when most economic activities are leading to ecological collapse, sustainability should be reprioritized with the help of the academic society, through the examples offered by applied research. The premises of this research were represented by bibliometric analyses and the results obtained have proven its importance, as well as the importance of certain scenarios involving solutions for improving the metabolism of nature.

The growth in population and economic activities has direct implications on the deterioration of the natural capital, especially when referring to the increase in greenhouse gas emissions. However, improvement is possible by empowering sustainable consumption and production patterns. Through the 2030 Agenda for Sustainable Development, the United Nations call for a mix of economic development, environmental sustainability, and social inclusion. The agenda also provides the instruments needed to track progress, as each Sustainable Development Goal has a set of indicators meant to assess various dimensions of sustainability. Energy productivity is only one of many, but still special because it reflects sustainable consumption behaviors and production patterns. The 2030 Climate Target Plan elaborated by the European Commission consolidates and brings its contribution to the aims of the 2030 Agenda for Sustainable Development by adding weight to the importance of the greenhouse gas emissions target. The objective of this research was to study the relationship between energy productivity, greenhouse gas emissions, biowaste recycling and nominal GDP in the EU in order to highlight the key of a smooth transition towards sustainable consumption behaviors and production patterns. The results show that recycling, greening the economy and energy productivity are the vectors of this transition.
