Economical evaluation of ecological benefits of the demand side management

2014

Environmental pollution and over-exploitation of non-renewable sources to find energy are current topics for the modern world that is now at having to deal with several issues such as the greenhouse effect, acid rain and climate change. In this study, the economical estimate of the savings in carbon dioxide obtained with a careful management of electrical loads is presented. Four particular scenarios are designed as case studies: Italy, France, United Kingdom and Germany. A comparison is presented with a similar study, made in 2007, when green energies were not yet very developed.

Global, National, or Market? Emerging REDD+ Governance Practices in Mozambique and Tanzania

2016

This article examines emerging governance practices in the REDD (Reducing Emissions from Deforestation and Forest Degradation) initiative. We examine three different general governance practices (neoliberal, post-national, and government-led practices) that have been applied in the interaction between international organizations and two REDD target countries: Mozambique and Tanzania. In these countries, we find that emerging REDD+ governance practices are a mixture of international organizations’ procedural practices and the target country’s established governance practices, whereas neoliberal practices are weakly expressed. These findings call into question the simplified assumption of re…

The Impact of the Spanish Foreign trade on its Real CO2 Emissions

2019

CO2 emissions are a global problem. This means that nothing or very little will change if only particular countries are involved. The aim of this paper is the attempt to show the real CO2 emissions of Spain as well as the impact of its trade on CO2 emissions in other countries in the world and in the EU in 2017. This study was conducted on the group of countries that are the major emitters of CO2 in the world including most of the EU members. Countries with negligible CO2 emissions were omitted. Actual CO2 emissions were obtained by applying the actual emission factor. This considers the transfer of CO2 in export products and services as well as those imported by particular countries. The r…

Energy efficient model for biogas production in farm scale

2011

Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…

Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection

2021

At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…

In-depth characterization of denitrifier communities across different soil ecosystems in the tundra

2022

Abstract Background In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N2O). However, the microorganisms involved in the cycling of N2O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N2O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra. Results We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then sear…

An integrated package for modelling and mapping urban traffic emissions and air and acoustic quality

2005

Urban activities and traffic movements have an important impact on the acoustic level and air pollution. The aim of the present paper is to assess the improvement of an environmental territorial information system, developed in 2003, useful as a decision support for town-planning and territorial management. The system born as a data base and as a tools of management for environmental problems is now improved and is able to calculate the noise levels and the correlate CO values. Since an urban area could be analyzed at a macro-scale level also the evaluation is at a macro scale level. Thanks to its flexibility, the modular system allows to meet the demands of a wide range of applications.

Simulation with a Torque Dynamometer of Pollutants Emission from Vehicles Near Urban Cross-Road

2002

Nowadays, the influence of the vehicular traffic on the degradation of urban atmosphere is focused on by researchers belonging to different fields in view of its prime importance for public health. The control of exhaust gases emission is primary in order to keep air pollution below the specified limits of the laws in force. In previous works the “medium car” characterises a country in modelling a pollutant in urban areas. This is the central parameter of a forecasting model proposed by Pignato and LoMastro, of pollutant concentration near urban cross-road with traffic lights in continue queue and platoon flow. The proofs have been carried on two classes of displacement vehicles and four cl…
