The electricity generation sector is far from sustainable; in Ontario, 77% of electricity consumed is generated from non-renewable sources such as coal, natural gas and nuclear. As a result, this sector contributes significantly to many environmental challenges including global warming, smog formation, and acid deposition. It is critical to improve the sustainability of electricity generation through the incorporation of sustainable design concepts. Sustainable design takes into account the environmental performance of a product or process over its entire life cycle (including design and development, raw material acquisition, production, use, and end-of-life). Innovative design has resulted in new technologies for electricity generation. Generating electricity from biomass is one of the alternative technologies which could have the potential to improve the sustainability of the electricity generation sector. In this research we examine various scenarios for displacing coal-based generation. Coal gasification is a mature technology and to replace some or all of the feedstock with biomass, a re-design of some portions of the electricity generation technology are required. The technical changes in the process depend on several issues including the physical and chemical characteristics of biomass. We evaluate the environmental performance of electricity generation from agricultural residues through conducting a life cycle inventory for three biomass-to-electricity scenarios for the Province of Ontario; 1) a 5% co-firing of agricultural residues with coal in existing coal plants, 2) a 15% co-firing of agricultural residues with coal in existing coal plants, and 3) a hypothetical power plant which produces electricity from 100% agricultural residues using biomass gasification technology. For comparison purposes, we analyze a current coal only option using plant specific data. We quantify life cycle energy use, greenhouse gas and air pollutant emissions for electricity. Our results suggest that on a life cycle basis electricity generated from biomass can achieve a reduction in greenhouse gas emissions of 4% (for the 5% biomass co-firing) to 96% (for the 100% biomass gasification) compared to the coal-only option. Similarly, reductions in air pollutant emissions (sulfur oxides, nitrogen oxides, and particulate matter) range from 4% to 98%. Our study indicates that life cycle analysis is a useful tool for assisting decision makers in the selection of more sustainable design options for future electricity generation.

The European Union (EU) is considered one of the most economically developed regions worldwide. It was driven by the mining industry for several decades. Despite certain changes in this area, a number of mineral and energy resources are still being mined in the EU. Nevertheless, mining activities are accompanied by many unfavorable phenomena, especially for the environment, such as greenhouse gas and air pollutant emissions. The great diversity of the EU countries in terms of the size of the “mining and quarrying” sector means that both the volume and structure of these emissions in individual countries varies. In order to assess the current state of affairs, research was conducted to look at the structure and volume of these emissions in individual EU countries. The aim of the study was to divide these countries into homogenous groups by structure and volume of studied emissions. In order to reflect both the specificity and diversity of the EU countries, this division was based on the seven most important gases (CO2, CH4, N2O, NH3, NMVOC, CO, NOx) and two types of particulate matter (PM 2.5, PM 10) emitted into the atmosphere from the sector in question. The volume of studied emissions was also compared to the number of inhabitants of each EU country and the gross value added (GVA) by the mining and quarrying sector. This approach enabled a new and broader view on the issue of gas and air pollutant emissions associated with mining activities. The artificial Kohonen’s neural networks were used for the analysis. The developed method, the analyses and the results constitute a new approach to studying such emissions in the EU. Research that looks only at the emission of harmful substances into the environment in relation to their absolute values fail to fully reflect the complexity of this problem in individual EU countries. The presented approach and the results should broaden the knowledge in the field of harmful substance emissions from the mining and quarrying sector, which should be utilized in the process of implementing the new European climate strategy referred to as “The European Green Deal”.

Biodiesel (BD) is often regarded as a carbon-neutral fuel. Many countries are investing resources in biodiesel technology development to respond to the need to improve energy sustainability and the threat of climate change. Since 2009, the South Korean Government has invested a considerable amount of money in developing marine BD (MBD) technology that converts carbon dioxide into diesel using marine microalgae cultivated in large quantities with the help of waste heat from nuclear power plants and/or coal-fired power plants. If the development is successful, 4800 tons of MBD a year, approximately 1820 cars fully fueled annually, will be produced from 2019. Furthermore, the South Korean Government is expected to continue to invest in MBD to improve the market share after 2019. Quantitative information about the public value of MBD technology development is widely demanded by the Government. This study aims to investigate the public value of MBD technology, the attributes of which it considers to be the reduction of greenhouse gas emissions, the mitigation of air pollutant emissions, new job creation, and the improvement of energy security. A choice experiment (CE) survey of 600 people was conducted during July 2016. The trade-offs among the attributes and the price were evaluated in the survey. The CE data were examined through a multinomial logit model. The marginal values for a 1%p reduction of greenhouse gas emissions, 1%p mitigation of air pollutant emissions, the creation of 100 new jobs, and an improvement of energy security caused by MBD technology development are computed to be KRW 1082.7 (USD 0.9), 918.1 (0.8), and 258.3 (0.2) per household per month, respectively.

AbstractThe overlap in sources of greenhouse gas and local air pollutant emissions creates scope for policy measures to limit global warming and improve air quality simultaneously. In a first step, we derive estimates for the air pollution mortality-related component of the social cost of atmospheric release for 6 pollutants and 56 regions in the world. Combining these estimates with emission inventory data highlights that sector contributions to greenhouse gas emissions and air pollution health impacts differ widely across regions. Next, simulations of future emission pathways consistent with the 2 °C and 1.5 °C targets illustrate that strengthening climate policy ambition raises the total value of air quality co-benefits despite lower marginal co-benefits per tonne of greenhouse gas emissions abated. Finally, we use results from a multi-model ensemble to quantify and compare the value of health-related ambient air quality co-benefits of climate policy across sectors and regions. On the global level, overall air quality co-benefits range from $8 to $40 per tonne of greenhouse gases abated in 2030, with median across models and scenarios of $18/tCO2e. These results mask strong differentiation across regions and sectors, with median co-benefits from mitigation in the residential and service sectors in India exceeding $500/tCO2e. By taking a sector- and region-specific perspective, the results presented here reveal promising channels to improve human health outcomes and to ratchet up greenhouse gas reduction efforts to bridge the gap between countries’ pledges and the global targets of the Paris Agreement.

Greenhouse Gas Abatement

Beef is often identified as one of the foods with the largest greenhouse gas (GHG) emissions, causing climate-conscious persons to seek changes in their diets. This study evaluated the ability of a household to reduce its GHG emissions by replacing conventional US beef with grass-fed beef and compared its effectiveness to three other strategies: replacing beef with chicken, becoming a vegetarian, and purchasing carbon offsets. These potential GHG-reducing strategies were considered within a model of a typical US household, using a framework that accounts for all household expenditures and carbon emissions. Replacing beef with chicken and adopting vegetarianism reduced the household’s GHG emissions by 1% and 3%, respectively. Grass-fed beef only reduced emissions if the GHG sequestration rate for pastureland and/or the price of grass-fed beef was high. It is shown that persons paying higher prices for grass-fed beef with the goal of smaller GHG emissions might want to consider buying conventional beef instead and using the savings to purchase carbon offsets. Also, although vegetarianism is often touted as a climate-friendly diet, the model shows that meat-eaters can achieve the same GHG reduction by spending only US$19 per year on carbon offsets. These results assume that additional land for grazing is acquired from recently abandoned cropland, which gives grass-fed beef its best chance at being climate-friendly. Alternative land-use assumptions would only reinforce the result that grass-fed beef does not emit less GHG emissions than conventional beef.
