The shale gas debate has taken center stage over the past decade in many European countries due to its purported climate advantages over coal and the implications for domestic energy security. Nevertheless, shale gas production generates greenhouse gas and air pollutant emissions including carbon dioxide, methane, carbon monoxide, nitrogen oxides, particulate matter and volatile organic compounds. In this study we develop three shale gas drilling projections in Germany and the United Kingdom based on estimated reservoir productivities and local capacity. For each projection, we define a set of emission scenarios in which gas losses are assigned to each stage of upstream gas production to quantify total emissions. The “realistic” (REm) and “optimistic” (OEm) scenarios investigated in this study describe, respectively, the potential emission range generated by business-as-usual activities, and the lowest emissions technically possible according to our settings. The latter scenario is based on the application of specific technologies and full compliance with a stringent regulatory framework described herein. Based on the median drilling projection, total annual methane emissions range between 150–294 Kt in REm and 28–42 Kt in OEm, while carbon dioxide emissions span from 5.55–7.21 Mt in REm to 3.11–3.96 Mt in OEm. Taking all drilling projections into consideration, methane leakage rates in REm range between 0.45 and 1.36% in Germany, and between 0.35 and 0.71% in the United Kingdom. The leakage rates are discussed in both the European (conventional gas) and international (shale gas) contexts. Further, the emission intensity of a potential European shale gas industry is estimated and compared to national inventories. Results from our science-based prospective scenarios can facilitate an informed discussion among the public and policy makers on the climate impact of a potential shale gas development in Europe, and on the appropriate role of natural gas in the worldwide energy transition.

The Impact

Germany and the United Kingdom have domestic shale gas reserves which they may exploit in the future to complement their national energy strategies. However gas production releases volatile organic compounds (VOC) and nitrogen oxides (NOx), which through photochemical reaction form ground-level ozone, an air pollutant that can trigger adverse health effects e.g. on the respiratory system. This study explores the range of impacts of a potential shale gas industry in these two countries on local and regional ambient ozone. To this end, comprehensive emission scenarios are used as the basis for input to an online-coupled regional chemistry transport model (WRF-Chem). Here we simulate shale gas scenarios over summer (June, July, August) 2011, exploring the effects of varying VOC emissions, gas speciation, and concentration of NOx emissions over space and time, on ozone formation. An evaluation of the model setup is performed, which exhibited the model’s ability to predict surface meteorological and chemical variables well compared with observations, and consistent with other studies. When different shale gas scenarios were employed, the results show a peak increase in maximum daily 8-hour average ozone from 3.7 to 28.3 μg m–3. In addition, we find that shale gas emissions can force ozone exceedances at a considerable percentage of regulatory measurement stations locally (up to 21% in Germany and 35% in the United Kingdom) and in distant countries through long-range transport, and increase the cumulative health-related metric SOMO35 (maximum percent increase of ~28%) throughout the region. Findings indicate that VOC emissions are important for ozone enhancement, and to a lesser extent NOx, meaning that VOC regulation for a future European shale gas industry will be of especial importance to mitigate unfavorable health outcomes. Overall our findings demonstrate that shale gas production in Europe can worsen ozone air quality on both the local and regional scales.

Abstract. China is the largest cement producer and consumer in the world. Cement manufacturing is highly energy-intensive, and is one of the major contributors to carbon dioxide (CO2) and air pollutant emissions, which threatens climate mitigation and air quality improvement. In this study, we investigated the decadal changes of carbon dioxide and air pollutant emissions for the period of 1990–2015, based on intensive unit-based information on activity rates, production capacity, operation status, and control technologies, which improved the accuracy of the cement emissions in China. We found that, from 1990 to 2015, accompanied by a 10.9-fold increase in cement production, CO2, SO2, and NOx emissions from China's cement industry increased by 626 %, 59 %, and 658 %, whereas CO, PM2.5 and PM10 emissions decreased by 9 %, 66 %, and 63 %, respectively. In the 1990s, driven by the rapid growth of cement production, CO2 and air pollutant emissions increased constantly. Then, the production technology innovation of replacing traditional shaft kilns with the new precalciner kilns in the 2000s markedly reduced SO2, CO and PM emissions from the cement industry. Since 2010, the growing trend of emissions has been further curbed by a combination of measures, including promoting large-scale precalciner production lines and phasing out small ones, upgrading emission standards, installing low-NOx burners (LNB) and selective noncatalytic reduction (SNCR) to reduce NOx emissions, as well as adopting more advanced particulate matter control technologies. Our study highlighted the effectiveness of advanced technologies on air pollutant emission control, however, CO2 emissions from China's cement industry kept growing throughout the period, posing challenges to future carbon emission mitigation in China.

Early in 1982 CSR Limited established an Oil and Gas Division. By 1983 this Division had recruited twenty-six overseas technical personnel mainly from Canada and the United Kingdom. The Company needed to recruit overseas because the skills required were not available in Australia.During 1983 a review of the recruitment and settlement of these personnel and their families was undertaken. The objectives of this review were to:improve the Company performance in the recruitment, induction and settlement of overseas recruits and their families;increase the likely "length of stay" in Australia of overseas recruits and their families;to address specific problems faced by recruits and their families in settlement in Australia.In depth interviews were conducted with twenty-one of the twenty-six recruits and their families using a structured interview format.The analysis of the interviews results revealed that:on average it took longer for those recruited in the United Kingdom to obtain immigration "approvals" and to physically relocate than those recruited in Canada;families with previous experience in relocating adapted and coped better with the physical move and resettlement than families without previous experience.The detailed results showed further that:While there was sufficient information provided about the job and department, there was dissatisfaction with the lack of detailed information about aspects of living in Australia, particularly: taxation; housing; bank mortgage arrangements; cost of living data and medical insurance.There were gaps in the expectations that many- recruits and their families had about living in Australia, such as climate, lifestyle and housing. This was attributed to an "oversell" through glossy brochures and "word pictures".The attention given to staff and their families on arrival was seen as a positive introduction to Australia and CSR's Oil and Gas Division.The provision of initial temporary accommodation in a single apartment complex for all overseas recruits and families in Adelaide assisted greatly in the induction and settlement process. It provided a high level of support especially for wives with young children. The "welcome waggon" group together with the assistance provided by the wives of senior executives were also positive influences in the settlement process.The most positive features seen in the move to Australia were career and lifestyle opportunities. On the other hand loss of disposable income was seen as a significant negative.From the results and analysis a detailed set of recommendations and actions were developed to improve company performance in recruitment and settlement. These recommendations were implementated prior to the 1984 recruiting mission to Canada, the United States and the United Kingdom.The preliminary results from the 1984 recruiting mission have resulted in:a reduction in recruiting lead time;quicker and more informed decision making by candidates and their families in accepting job offers;more professional preparation of both the recruiting teams and the company's agents overseas.
