Standards as a controlling mechanism: Methods and effects of carbon footprinting in the logistic sector. Carbon footprints describe the greenhouse gas emissions of predefined objects, such as products, companies, persons or transport units. Corresponding emission calculation standards have been developed and their application increased over the past decade. The article discusses this development, the current state of implementation and open questions regarding application and harmonization using the example of the logistic sector. Additionally, the author explores the question, how carbon footprints contribute to CO

Viticulture faces two challenges regarding climate change: adapting and mitigating greenhouse gas emissions. Are these two challenges compatible? This is one of the questions to which Adviclim project (Life project, 2014–2019) provided tools and answers. The assessment of greenhouse gas emissions was implemented at the scale of the plot using a life cycle approach: calculating the carbon footprint. This approach makes it possible to take into account the emissions generated during each stage of the life cycle of a product or a service: in this case, the cultivation of one hectare of vine for one year. Carbon footprint was assessed for the 5 pilot sites of the Adviclim project: Saint-Emilion (France), Coteaux du Layon/Samur (France), Geisenheim (Germany), Cotnari (Romania) and Plompton (United Kingdom). An important work for primary data collection regarding observed practices was carried out with a sample of reresentative farms for these 5 sites, and for one to three vintages depending on the site. Beyond the question asked in the project, the calculation of these carbon footprints made it possible to (i) make winegrowers aware of the life cycle approach and the share of direct emissions generated by viticulture, (ii) acquire new references on the technical itineraries and their associated emissions, (iii) improve the adaptation of the methodology for calculating the carbon footprint to viticulture.

Farm Types

Greenhouse gas emissions from farms can be suppressed in two ways: by curtailing the release of these gases (especially N2O and CH4), and by storing more carbon in soils, thereby removing atmospheric CO2. But most practices have multiple interactive effects on emissions throughout a farm. We describe an approach for identifying practices that best reduce net, whole-farm emissions. We propose to develop a “Virtual Farm”, a series of interconnected algorithms that predict net emissions from flows of carbon, nitrogen, and energy. The Virtual Farm would consist of three elements: descriptors, which characterize the farm; algorithms, which calculate emissions from components of the farm; and an integrator, which links the algorithms to each other and the descriptors, generating whole-farm estimates. Ideally, the Virtual Farm will be: boundary-explicit, with single farms as the fundamental unit; adaptable to diverse farm types; modular in design; simple and transparent; dependent on minimal, attainable inputs; internally consistent; compatible with models developed elsewhere; and dynamic (“seeing”into the past and the future). The Virtual Farm would be constructed via two parallel streams - measurement and modeling - conducted iteratively. The understanding built into the Virtual Farm may eventually be applied to issues beyond greenhouse gas mitigation. Key words: CO2, N2O, CH4, agroecosystems, models, climate change

The problem of increasing energy efficiency in commercial shipping has been in the focus of attention of many specialists over the past few decades. The adopted and entered into force resolutions of the International Maritime Organization (IMO) require ship-owners to develop and implement energy efficiency management plans. Considerable and increased attention is now being paid to the solution of this problem. However, it has not yet been possible to achieve real practical results – commercial shipping already accounts for more than 3 % of greenhouse gas emissions, and this value is growing from year to year. The reason for this effect is the practically absence of a systematic scientifically grounded approach to the issue. Management of carbon dioxide emissions into the atmosphere is mainly in the operational phase of the ship, although the foundations are laid during the design, construction, modernization and refurbishment phases. This study is aimed at developing a comprehensive model for managing the energy efficiency of a ship throughout the entire life cycle. It is proposed to use the cost of a full cycle and the coefficient of energy efficiency as target functions of the model. A method for solving the problem of two-criterion optimization is proposed. The use of this model will be able to significantly reduce the amount of greenhouse gas emissions

Emissions Trading System

Significance With the advent of China’s national emissions trading system in the past year, carbon prices now cover more than one-fifth of global greenhouse gas emissions. Yet doubts remain over whether they are high enough to force decarbonisation. Impacts Higher carbon prices will be more effective in curbing emissions than the relatively low prices that have prevailed in the past. Germany’s new coalition government will include the Greens and Free Democrats, parties committed to carbon dividends and carbon pricing. The successful rollout of this policy in Germany could serve as a model for Europe and beyond.

Abstract Policy support for renewable energy has increased considerably over the past decade. Two drivers underpin this trend: first, the effort to constrain growth in greenhouse-gas emissions and secondly, the concerns to diversify the supply mix (promoted particularly by high oil prices, especially in 2005–2008). To address these concerns, more and more governments are adopting targets and taking measures to increase the share of renewables in the energy mix. Worldwide, traditional and modern renewables together supplied 27% of total demand for heat, or 1059 Mtoe, in 2008. This increases to nearly 1400 Mtoe (1 Mtoe = 42 PJ) in 2035 in the New Policies Scenario, meeting 29% of total demand for heat. The share of modern renewables in total renewables for heat grows from 29% to 48%. This paper is a comparison analysis of the global and the Hungarian renewable energy trends.
