There is no doubt Sustainability reaching is essential. Natural resources rational use is extremely important to human development. Beyond the years, this preoccupation led various institutions to elaborate legislation and international guides, as Kyoto protocol, to satisfy sustainability conditions. Agenda 2030 is the most recent instrument, whose proposals attempt to these conditions. Within this context, human activity related to Chemistry is noteworthy: to guarantee all sustainable aspects in a procedure is a great challenge. The assessment of Sustainability in Chemistry is performed by green metrics calculations, whose utility is most appropriate in comparison of procedures than in a single procedure assessment. Due to problematics with the utilization of metrics, related to: simplifications leading to pseudo-results, need of various misunderstanding calculations and incorrect adoption of metrics, an environmental metric that attempts to current necessities related to materials and energetics consumption and to assessment of sustainability in individual chemistry procedures is proposed. The metric was elaborated aiming to attempt all environmental requirements of chemical sustainability in a simplified and reliable manner, basing on bibliographic search and expertise. The metric elaboration has a combined approach, in which reference values are established to the main indicators of sustainability, using a Soft System Methodology (SSM).

Hot-mix asphalt used in pavement layers is produced by asphalt plants. In Brazil, despite the fact that these industrial units produce greenhouse gases, no control or measurement protocol has yet been established. This study aims to quantify emissions in different asphalt plants, in terms of carbon dioxide equivalent (CO2eq) and energy consumption. Asphalt plants were selected according to their type (batch or drum mix); production capacity (80 to 340 t/h), and whether mobile or fixed. In each plant, emissions were quantified and the energy consumption spent on drying and heating aggregates in the dryer drum was evaluated. The fuels used in the drier drum such as low pour point (LPP) oil, liquefied petroleum gas (LPG), and natural gas (NG) were evaluated and compared. The methodology consisted of surveying the thermal power of the dryer drum specified on the suppliers' catalog to calculate the volume of fuel required per ton of asphalt mixture produced. Based on the criterion of the lower calorific value of each fuel, the volume of fuel used was calculated according to the production of the asphalt plants. Through the GHC protocol tool, the quantification of emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) gases was obtained, and then transformed into CO2eq emissions. As a result, lower energy consumption was observed in the mobile batch plants and higher consumption in the mobile counterflow drum mix plants. On average, 27.69% less energy per ton of processed aggregate was needed compared to the mobile counterflow plants. The use of natural gas in the dryer drum and for all plant models was the least emissive fuel. The results showed that for the mobile batch type with a capacity of 140 t/h, the emission was 13.62 kg of CO2eq / t. On the other hand, with the mobile counterflow type with a capacity of 200 t/h, 13.64 kg of CO2eq/t was produced. Finally, with the fixed counterflow type with a production capacity of 240 t/h and 300 t/h, emissions of 13.67 kg of CO2eq/t were obtained. Through this study, the mobile batch plant with a capacity of 140 t/h using natural gas showed the least environmental impact. When natural gas was used, this model obtained energy consumption and emissions 54.5% lower than the mobile counterflow model with a capacity of 50 t/h which showed the worst environmental performance.

Strategic Environmental Assessment (SEA) aims to facilitate both integration and assessment of opportunities and threats for action strategies within the framework of sustainable development. Its stages comprise Screening, which analyzes its need, Scoping, which establishes the range of environmental issues to be covered, Analysis, in which the Environmental Report is prepared, Decision-Making, Follow-up, in which both Monitoring and Follow-up of the assessment are conducted, and finally Consultation. Three types of effectiveness approaches, namely procedural effectiveness, substantive effectiveness, and transactional effectiveness can be identified. This article addresses the effectiveness of SEA in Brazil, Ireland, and Scotland through a comparative analysis, since it enables rich discussions on the subject.

Environmental impact assessment (EIA) is a decision-making tool and in many cases is a legal requirement in projects with activities potentially causing environmental degradation. In the case of agroecological projects, negative impacts are not allowed and an assessment is important to identify factors that distance them from the agroecological proposal. Based on the literature, the EIA, in general, is done with electronic spreadsheets, there is no software focused on the process. In view of this, the objective of this article was to carry out a diagnosis of environmental impacts in the Brígida Irrigation Project - Orocó/PE during the planting of different crops and animal husbandry, presenting a system to facilitate this task, named SAIA - Impact Assessment System Environmental, which can point out impacts that detract from an agroecological theme project. For this, after a survey on EIA techniques and agroecological projects, on the basis of scientific works and patents, the SAIA was validated in that Project, with questionnaires being applied with the participating family farming producers, to align the tool to the agroecological proposal. The diagnosis allowed us to conclude that there are negative impacts that keep the Project away from agroecology for all analyzed crops and creations. It is noteworthy that the number of impacts is not fixed for each type of crop, as it depends on how the steps are carried out. Furthermore, there was good acceptance of the tool, with suggestions, which were accepted, bringing SAIA closer to the reality of producers.

This article aimed to present the goals of the ABC Plan for low-carbon agriculture, and uses the multiple regressions modeling technique to investigate economic activity variables in relation to CO2 emissions over the period from 1990 to 2018 in all Brazilian states. The results show that the CO2 emissions in the states, have the same behavior as the land use change timeline, and that public policies and society actions were fundamental to the decrease verified in both CO2 emissions and the change in use, of the land observed from the year 2004 until 2010. From this year, followed a trend of stability in CO2 emissions and land use change. Another important characteristic is that despite the decrease in the number of deforestations, economic activities continued to grow in the regions, which demonstrates that there may be an increase in production even though the numbers of deforestation and CO2 emissions are decreasing. This information, strengthen the Low Carbon Agriculture Program, as the main strategy for the development of the productive sector, mainly for sustainable agriculture.

Analyze the implications of the configuration of the Sectors that make up the Water Supply Systems (WSSs) in the municipality of Belém, capital of the state of Pará, on their economic sustainability. The research was developed in three stages. The first stage consisted of identifying and collecting information regarding the WSSs operated by Companhia de Saneamento do Pará – COSANPA. In the second stage, operational and commercial indicators were determined for both Sectors selected as the most suitable for comparison, in this case the 12th Sector and the 23rd Sector. In the last stage, an analysis of the economic sustainability of selected Sectors was performed. It was verified that 04 of the 39 WSSs collect raw water from a surface water source, while the other 35 WSSs use deep wells (about 270 meters deep) to collect water from Pirabas artesian aquifer. In addition, operational efficiency indicators were calculated, such as the “Distribution Losses Index” – 69,08% (12th Sector) and 72,67% (23rd Sector), and economic sustainability indicators, such as the “Total Expense with the Services per Billed Cubic Meter” – R$1,92/m³ (12th Sector) and R$1,29/m³ (23rd Sector). In conclusion, due to the classification of both studied Sectors, regarding operational efficiency and economic sustainability, as inefficient and partially sustainable respectively, it is recommended to improve the operational and comercial management of the regional concessionaire, in compliance with the premises of Law No. 14.026/2020 and to ensure the economic and financial balance of the service provider.

The development of a country is intimately linked to the industrial development that is responsible for wealth generation, jobs and income, however, it is followed by serious environmental impacts caused by production and incorrect disposal of waste. The present research aimed to characterize the solid waste management system in metallurgic companies from Joaçaba/SC. For this, a research instrument was applied containing twelve open questions for the heads of seven companies. The questions included the identification of solid waste generated in the production process and the disposal method, as well as information about environmental licensing and reverse logistic. The research showed that only one company has an environmental management system and has a better understanding about its environmental responsibilities, both the management of waste generated by the production process and the importance of preserving the environmental.
