Este trabalho busca analisar o quão determinante seriam as políticas precificação de emissões de gases do efeito estufa (GEE) na competividade logística agroindustrial no Brasil. Para isso, considerou dois projetos de infraestrutura logística em fase de pré-concessão, Ferrogrão e Ferrovia Paraense, visando o escoamento da produção de grãos no estado do Mato Grosso. Assim, determinando as áreas de influência não apenas por meio dos custos de transporte, bem como com a incorporação dos custos provenientes das emissões, as soluções logísticas intermodais, considerando os dois projetos, indicam que essas são as que apresentam potencial maior área de influência para captação das menores emissões GEE. Cenário esse corroborado, visto que, consideradas elevações no custo por tonelada de CO2 emitido, o escoamento por meio da Ferrogrão e da Ferrovia Paraense se tornariam maiores.Palavras-chave: Precificação.

Two transportation infrastructure projects are analyzed, Ferrogrão and Pará Railway. By determining the areas of influence not only through transportation costs, as well as the incorporation of emissions costs, intermodal logistics solutions, considering the two projects, indicate that these are the ones with the largest potential area of influence to capture the lowest GHG emissions. This is corroborated as, considering increases in the cost per ton of CO2 emitted, the flow through Ferrogrão and Pará Railway would become larger.Keywords: Pricing. Emissions. Agribusiness.

Abstract A review of conventional, unconventional, and advanced geothermal technologies highlights just how diverse and multi-faceted the geothermal industry has become, harnessing temperatures from 7 °C to greater than 350 °C. The cost of reducing greenhouse emissions is examined in scenarios where conventional coal or combined-cycle gas turbine (CCGT) power plants are abated. In the absence of a US policy on a carbon tax, the marginal abatement cost potential of these technologies is examined within the context of the social cost of carbon (SCC). The analysis highlights that existing geothermal heat and power technologies and emerging advanced closed-loop applications could deliver substantial cost-efficient baseload energy, leading to the long-term decarbonization. When considering an SCC of $25, in a 2025 development scenario, geothermal technologies ideally need to operate with full life cycle assessment (FLCA) emissions, lower than 50 kg(CO2)/MWh, and aim to be within the cost range of $30−60/MWh. At these costs and emissions, geothermal can provide a cost-competitive low-carbon, flexible, baseload energy that could replace existing coal and CCGT providing a significant long-term reduction in greenhouse gas (GHG) emissions. This study confirms that geothermally derived heat and power would be well positioned within a diverse low-carbon energy portfolio. The analysis presented here suggests that policy and regulatory bodies should, if serious about lowering carbon emissions from the current energy infrastructure, consider increasing incentives for geothermal energy development.

Aim of study: Reduction of the greenhouse gas (GHG) emissions derived from food production is imperative to meet climate change mitigation targets. Sustainable mitigation strategies also combine improvements in soil fertility and structure, nutrient recycling, and the use more efficient use of water. Many of these strategies are based on agricultural know-how, with proven benefits for farmers and the environment. This paper considers measures that could contribute to emissions reduction in subsistence farming systems and evaluation of management alternatives in the Central Andes of Ecuador. We focused on potato and milk production because they represent two primary employment and income sources in the region’s rural areas and are staple foods in Latin America.Area of study: Central Andes of Ecuador: Carchi, Chimborazo, Cañar provincesMaterial and methods: Our approach to explore the cost and the effectiveness of mitigation measures combines optimisation models with participatory methods.Main results: Results show the difference of mitigation costs between regions which should be taken into account when designing of any potential support given to farmers. They also show that there is a big mitigation potential from applying the studied measures which also lead to increased soil fertility and soil structure improvements due to the increased soil organic carbon.Research highlights: This study shows that marginal abatement cost curves derived for different agro-climatic regions are helpful tools for the development of realistic regional mitigation options for the agricultural sector.

It is established that the interprovincial transportation in bus terminals of the Cities such as Ambato, Riobamba, Salcedo, Latacunga and Guaranda have contributed to the build-up of external costs of Greenhouse Gases (GHG) The climate change costs are calculated by multiplying the carbon emissions by the cost factor. To quantify the GHG emissions, this study has taken into account of both the direct and indirect sources of the Greenhouse Gas Protocol (GHG), as well as the ISO 14064.1: 2006 standard. In view thereof, it was found that the 11 bus terminals of the five cities, namely Latacunga, Riobamba Salcedo, Ambato, Guaranda-which accounts for around 3225 buses, had accounted for the emissions of 25,746.8 tCO2eq, 37,404.6 tCO2eq, 8,762.7 tCO2eq, 92,364.9 tCO2eq, 31,990.3 tCO2eq, respectively. Simply, the average load of such pollution produced per vehicle was 60.8 tCO2eq. and the total emissions were 196,269.3 tCO2eq with an estimated GHG contamination cost of €27,477,702 per year.

Fuel ethanol produced from sugar and starch is to be complemented and eventually even replaced by ethanol produced from lignocellulose, in order to mitigate possible competition with the food sector. A first step towards this goal may be a combination of both feedstocks in one plant. This is topic of the presented study, whether synergies in lowering the production costs and greenhouse gas (GHG) emissions can be reached through combined processing was topic of the presented study. A greenfield straw ethanol plant, a wheat ethanol plant and an integrated plant, processing both wheat grain and straw were developed and compared regarding the resulting GHG emissions and production costs. Despite showing the best results with regard to greenhouse gas emissions, greenfield straw ethanol production is related to relatively high production costs. The wheat based ethanol plant again is associated with higher GHG emissions, but low production costs. By combining straw and wheat processing, resulting production costs of EUR651/m3 ethanol are at a level close to market prices, but the same mitigation potential as separate straw based ethanol cannot be reached. The low level of 16.1 g CO2-eq/MJ of straw based ethanol results mainly from the use of the agricultural residue as feedstock and the use of the internally produced lignin to ensure the steam supply. In the assessment of the production costs, feedstock costs are one of the most relevant parameters. Since straw prices are not available from market statistics, an assessment of Germany’s sustainable straw potential in a high spatial resolution has served to calculate straw supply costs. Depending on the exact location of the plant, a range of EUR50/t to EUR90/t (fresh matter) was found to be the cost for straw provision.

We integrate life cycle indicators for various technologies of an energy system model with high spatiotemporal detail and a focus on Europe and North Africa. Using multi-objective optimization, we calculate a pareto front that allows us to assess the trade-offs between system costs and life cycle greenhouse gas (GHG) emissions of future power systems. Furthermore, we perform environmental ex-post assessments of selected solutions using a broad set of life cycle impact categories. In a system with the least life cycle GHG emissions, the costs would increase by ~63%, thereby reducing life cycle GHG emissions by ~82% compared to the cost-optimal solution. Power systems mitigating a substantial part of life cycle GHG emissions with small increases in system costs show a trend towards a deployment of wind onshore, electricity grid and a decline in photovoltaic plants and Li-ion storage. Further reductions are achieved by the deployment of concentrated solar power, wind offshore and nuclear power but lead to considerably higher costs compared to the cost-optimal solution. Power systems that mitigate life cycle GHG emissions also perform better for most impact categories but have higher ionizing radiation, water use and increased fossil fuel demand driven by nuclear power. This study shows that it is crucial to consider upstream GHG emissions in future assessments, as they represent an inheritable part of total emissions in ambitious energy scenarios that, so far, mainly aim to reduce direct CO2 emissions.

Abstract Forecasts indicate that China’s non-carbon dioxide (CO2) greenhouse gas (GHG) emissions will increase rapidly from the 2014 baseline of 2 billion metric tons of CO2 equivalent (CO2e). Previous studies of the potential for mitigating non-CO2 GHG emissions in China have focused on timeframes through only 2030, or only on certain sectors or gases. This study uses a novel bottom-up end-use model to estimate mitigation of China’s non-CO2 GHGs under a Mitigation Scenario whereby today’s cost-effective and technologically feasible CO2 and non-CO2 mitigation measures are deployed through 2050. The study determines that future non-CO2 GHG emissions are driven largely by industrial and agricultural sources and that China could reduce those emissions by 47% by 2050 while enabling total GHG emissions to peak by 2023. Except for F-gas mitigation, few national or sectoral policies have focused on reducing non-CO2 GHGs. Policy, market, and other institutional support are needed to realize the cost-effective mitigation potentials identified in this study.

Despite the importance of labour and overhead costs to both funders and performers of research in South Africa, there is little published information on the remuneration structures for researchers, technician and research support staff. Moreover, there are widely different pricing practices and perceptions within the public research and higher education institutions, which in some cases do not reflect the underlying costs to the institution or the inherent value of the research. In this article, data from the 2004/5 Research and Development Survey have been used to generate comparative information on the cost of research in various performance sectors. It is shown that this cost is lowest in the higher education institutions, and highest in the business sector, although the differences in direct labour and overheads are not as large as may have been expected. The calculated cost of research is then compared with the gazetted rates for engineers, scientists and auditors performing work on behalf of the public sector, which in all cases are higher than the research sector. This analysis emphasizes the need within the public research and higher education institutions for the development of a common pricing policy and for an annual salary survey, in order to dispel some of the myths around the relative costs of research, the relative levels of overhead ratios and the apparent disparity in remuneration levels.
