Nearly three billion people in low- and middle-income countries (LMICs) rely on polluting fuels, resulting in millions of avoidable deaths annually. Polluting fuels also emit short-lived climate forcers and greenhouse gases (GHGs). Liquefied petroleum gas (LPG) and grid-based electricity are scalable alternatives to polluting fuels but have raised climate and health concerns. Here, we compare emissions and climate impacts of a business-as-usual household cooking fuel trajectory to four large-scale transitions to gas and/or grid electricity in 77 LMICs. We account for upstream and end-use emissions from gas and electric cooking, assuming electrical grids evolve according to the 2022 World Energy Outlook’s “Stated Policies” Scenario. We input the emissions into a reduced-complexity climate model to estimate radiative forcing and temperature changes associated with each scenario. We find full transitions to LPG and/or electricity decrease emissions from both well-mixed GHG and short-lived climate forcers, resulting in a roughly 5 millikelvin global temperature reduction by 2040. Transitions to LPG and/or electricity also reduce annual emissions of PM2.5 by over 6 Mt (99%) by 2040, which would substantially lower health risks from Household Air Pollution. Primary input data was collected from the following sources: Baseline household fuel choices - WHO household energy database (https://www.nature.com/articles/s41467-021-26036-x) End-use emissions - US EPA lifecycle assessment of household fuels (https://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=339679&Lab=NRMRL&simplesearch=0&showcriteria=2&sortby=pubDate&timstype=Published+Report&datebeginpublishedpresented) Upstream emissions - Argonne National Labs GREET Model (https://greet.es.anl.gov/index.php) Current and future population estimates - UNECA (http://data.un.org/Explorer.aspx?d=EDATA) Input data was processed by defining household fuel choice scenarios, estimating national household fuel consumption based on these scenarios, and applying fuel-specific emission factors to create country-specific emission pathways. These emission pathways were input into the FaIR model (https://zenodo.org/record/5513022#.Yt_jfHbMLb0) which generated additional data for each scenario including time series of pollution concentrations, radiative forcing, and temperature changes. All data is provided in CSV format. Nothing proprietary is required. 

This dataset contains terrestrial fluxes of nitrous oxide (N2O), methane (CH4) and ecosystem respiration (carbon dioxide (CO2)) calculated from static chamber measurements in riparian buffers of oil palm plantations on mineral soil, in Riau, Sumatra, Indonesia. Measurements were made monthly, from January 2019 until September 2021, with a break from April 2019 to October 2019 to allow for felling and replanting, and another break from January 2021 to June 2021 due to Covid-19 restrictions. To help to reduce the environmental impact of oil palm plantations, riparian buffers are now required by regulations in many Southeast Asian countries. The experiments were conducted to investigate the impact of greenhouse gas emissions from the riparian buffers. Research was funded through NERC grant NE/R000131/1 Sustainable Use of Natural Resources to Improve Human Health and Support Economic Development (SUNRISE) Greenhouse gas concentrations were measured using static chambers, enclosed for 45 minutes. Multiple regressions (including linear and hierarchical multiple regression) were fitted to calculate the best fit flux, using the RCflux R package, written by Dr Peter Levy (UKCEH).

Variation in food resources can result in dramatic fluctuations in the body condition of animals dependent on those resources. Decreases in body mass can disrupt patterns of energy allocation and impose stress, thereby altering immune function. In this study we investigated links between changes in body mass of captive cane toads (Rhinella marina), their circulating white blood cell populations, and their performance in immune assays. Captive toads that lost weight over a 3-month period had increased levels of monocytes and heterophils and reduced levels of eosinophils. Basophil and lymphocyte levels were unrelated to changes in mass. Because individuals that lost mass had higher heterophil levels but stable lymphocyte levels, the ratio of these cell types was also higher, partially consistent with a stress response. Phagocytic ability of whole blood was higher in toads that lost mass, due to increased circulating levels of phagocytic cells. Other measures of immune performance were unrelated to mass change. These results highlight the challenges faced by invasive species as they expand their range into novel environments which may impose substantial seasonal changes in food availability that were not present in the native range. Individuals facing energy restrictions may shift their immune function towards more economical and general avenues of combating pathogens.

Dr. Irina Oliseveca presented a poster entitled, "Comprehensive Comparison of Anodic Alumina Membrane Infiltration Methods: Electrolyte Selection, Membrane Stability and Flow Rate Characterization". Abstract: Nanoporous anodic aluminum oxide (AAO) is one of the most popular and cost-effective platforms for various applications from molecular separation to drug delivery and energy generation. Its unique optical and electrochemical properties are extensively explored for biosensing and energy-harvesting applications. One of the main challenges in the effective application of AAO membranes in different devices involving liquid media is control of the nanopore filling and percentage of the active nanopore channels. In this work, 50 mm thick AAO membranes with pore diameters 25 nm and 40 nm were fabricated using the two-step anodization in oxalic and sulfuric acids and infiltrated with aqueous electrolytes (NaCl, NaClO4, Na2SO4) by different infiltration methods. The concentration of the solution varied from 10-6 mol/dm3 to 1 mol/dm3. The percentage of infiltrated nanochannels was controlled using electrochemical impedance spectroscopy (EIS) measurements. The morphology of the membranes before and after infiltration was characterized using scanning electron microscopy (SEM). A comprehensive analysis of different infiltration methods for nanoporous AAO membranes with aqueous electrolytes was carried out, and the advantages and drawbacks of each filling method were identified. Between the studied methods, the hydrostatic pressure-induced infiltration technique was determined as the most effective method for filling more than 90% of the pore channels. The dependence of filtration rate on electrolyte concentration was determined for both types of AAO membranes. The changes in the filtration rate can be used to indicate the occurrence of damaging/degradation processes in AAO pore channels. The dependence of solution flow rate or AAO membrane resistance per unit of the active area of the membrane on electrolyte concentration can be used to investigate the contribution of electrokinetic effects that occur in nanochannels and are especially noticeable when electrical double layers along the inner walls of the nanopores are completely or partially overlapped.

Food contamination is common during the production, distribution and consumption of processed and agricultural commodities all over the world. Knowledge of the mycobiota in crops and food is essential for understanding and prevention of spoilage. In addition to possible spoilage, the growth of filamentous fungi in food can result in the production of mycotoxins and other secondary metabolites, which may impact human and animal health. Therefore, among the food safety issues, the occurrence of fungal species able to produce toxic metabolites on the agro-food products has acquired great relevance (1). The production of mycotoxins is commonly species-specific, but it also influenced by other factors, like substrate, genetic variation, temperature, water activity etc. The knowledge of the molecular mechanisms that regulate these interactions remains very limited, however its understanding is fundamental to determine health risks associated with mold-spoiled foods and beverages. Mycotoxins are produced by a wide variety of molds, mainly Aspergillus, Fusarium and Penicillium. In general, five mycotoxins are the most significant agriculturally and have a worldwide distribution: aflatoxins, deoxynivalenol, fumonisins, ochratoxin A, and zearalenone. In addition, T-2 and HT-2 toxins can be a problem in cool temperate and generally wet areas, and Patulin is receiving increasing attention (2). Studies on toxigenic molds and its biodiversity have become highly relevant, due to the increased awareness of mycotoxins impact on human and animal health, the public concern for food safety and wastage, as well as the effects of climate change, which generate new combinations mycotoxins/host plants/geographical areas. Economic losses due to mycotoxins are high in both domestic and international trades. Also costs because affection of human and animal health are relevant and observed both in developed and developing Countries. Climate change also influence the physiology of the crops and the biodiversity of the fungi, and are modifying the risk maps of mycotoxin contamination. In this respect, recent advances confirm the importance of providing provisional models for mycotoxin occurrence in relation to climate change (3). In this context some important future challenges are in progress :i) impact reduction of fungi in staple food/feed chains; ii) new methodologies for detection and quantification; iii) new ecophysiology data in the context of climate change scenarios; iv) development of novel prevention strategies at different stages of the food and feed chains. Finally, over the past 50 years, diets in all countries have converged on a few sources of dietary starch, increasing the risk of exposure to mycotoxins, that can be evaluated by monitoring biological fluids such as blood and urine. The health risk from multi-mycotoxin exposure is still unclear since the additives and/or synergistic effects of mycotoxins have been poorly investigated. Nevertheless, the growing interest in understanding the combined effect of mycotoxin mixtures, will improve the current risk assessment capability at worldwide level.

The furious pace of global urbanisation has serious impacts on the long-term sustainability and health of the local communities in which we live. The debate about relationships between population size, environmental management and human well-being must now encompass the fundamental concept of sustainability (Rees, 1992; WCED, 1990; McMichael, 2002; Hancock, 1996). Increasingly, the local municipal level is the most influential setting in which to change our relationship with the environment (Chu, 1994; Chu et al., 2000). In the 1980s, the World Health Organisation (WHO) met this global challenge by advocating healthy public policy and laying foundations for its global Healthy Cities Movement. Significant support developed in the early nineties for participatory health planning action in local government: over 2000 cities world-wide developed municipal public health plans (MPH Plans). The Healthy Cities Movement through regional networks of cities and towns encouraged government partnerships with non-government agencies and industry, to anticipate and mitigate urbanisation’s negative impacts. In Queensland eighteen local governments have developed and implemented MPH Plans using a seven-step process (Chapman and Davey, 1997; WHO (1997b) to improve local planning for health and address the social determinants of health through agency collaboration. There is however limited understanding and evidence of the success factors for the effective implementation of MPH Plans. Studies of the evaluation of Municipal Public Health Planning (MPHP) approaches have focused predominately on the evaluation of the process of planning, without conducting comprehensive evaluation of its implementation. The organisational barriers that contribute to ineffective health-planning implementation have not been well researched and documented. Here lies the gap in the research: MPHP requires thorough qualitative assessment, not only of the planning process, but also the implementation impacts. This research explores the achievements, barriers and success factors associated with MPHP implementation in local government organisations by developing a process and impact evaluation framework and applying it to two MPHP projects in Queensland: one, local planning in an expanding tourist city of over 400,000 people; the second, a regional approach involving two provincial cities with a combined population of 100,000 residents. The research examines the degree of collaboration resulting from health planning and assesses if the aims of the MPH Plans have been met. MPHP is both a health promotion tool and a strategic business planning process applied in local communities: this research seeks to understand more about organisational strategic management issues that act as barriers to planning or impact on the success of planning outcomes. This study design uses qualitative methods with a triangulation approach to analyse and understand the complexities of MPH Plan implementation. Grounded theory provides a methodology for interpreting meanings and discovering themes from the comprehensive process and impact evaluation consisting of preliminary cases studies, key informant interviews, using specific process and impact indicator questions and an analysis of MPHP models compared to other CPHP models and legislative frameworks. The impacts of the intervention are discussed and relate to the implementation effects of MPHP on individuals and organisations including council, government and non-government agencies and on the community. Achievements and barriers associated with MPHP are identified and discussed. Three main factors emerged. Firstly, MPHP had significantly increased the degree of intersectoral collaboration between the agency project partners, with particular success in clarifying the role of agencies in the management and delivery of public health services. The principles of successful partnerships need to be further articulated in local government settings to successfully implement MPHP. Secondly, positive political and organisational support was found to be a critical factor in the success of the planning implementation. Thirdly, and most importantly, the aims of the MPHP had not been substantially met due to a lack of financial and human resources. The study concluded that, although MPHP has strengths and weaknesses compared to other CPHP models, its features most suit local government. Success factors recommended for effective MPHP include formalising collaboration and partnerships and improved agency organisational governance in planning; building individual and organisational capacity to strengthen strategic planning; integrating the many layers of regulatory planning in local government and other agencies; sustaining planning structures and processes through regulation and commitment to investment in implementation stages of MPHP. The study’s major recommendation is that, for MPHP local government should facilitate a three-dimensional platform approach: healthy governance – long-term vision, recognising the many layers of planning, supported by state legislation and local industry and with awareness of legislative planning frameworks; a platform mechanism – sustaining agency networking, hosting the stakeholder forum, supporting the advisory committee, enhancing communication; and strategy implementation – in the context of an improved understanding of organisational behaviour, local government and agencies must action priority strategies, formalising agency partners responsibility, articulating desired outcomes, monitoring progress and evaluation. This recommended Platform Approach to MPHP provides an effective model for managing and implementing future MPH Plans, allocating resources three ways: to build people’s capacity to engage in planning mechanisms, to build organisational capacity to manage planning outcomes and to build more effective Healthy Cities planning approaches. The MPHP evaluation framework developed in this thesis could be used to evaluate other MPHP projects in local governments both in Australia and internationally.

As a consequence of a fast-paced technological evolution along with the acknowledgment of utilizing clean and renewable energy resources over fossil fuels, the importance of energy storage devices is widely recognized. The electrochemical capacitor (EC), commonly known as a supercapacitor or ultracapacitor, is an energy storage device that is already being used in portable consumer electronics, electrification of transportation, and grid-level applications. High power density and long cycle life are the two most prominent properties of ECs, thanks to the electrostatic nature of their charge storage mechanism. These properties are well utilized in a system where ECs are used as a backup power-boosting device to rechargeable batteries. By providing the peak power required, they eventually prolong the battery lifetime. However, the relatively low energy density of ECs compared to rechargeable batteries limits their application as a standalone device. In addition, low operating voltage, adverse self-discharge rate, severe leakage current, elevated temperature incompatibility are some of the crucial issues that are preventing the widespread application of ECs. Besides a general discussion about ECs, the main objective of this thesis is to identify and address the above-mentioned critical challenges, and to propose and demonstrate corresponding solutions. Firstly, it is revealed that utilizing a redox-active KBr electrolyte can enhance both operating voltage and capacitance, and hence increases energy density without sacrificing power density or cycle life. Secondly, an evaluation of elevated temperature influence on the capacitive performance of ECs containing ionic liquid (IL) electrolyte demonstrates a high working temperature beyond 120 °C. Thirdly, a systematic investigation of ECs containing IL at elevated temperatures shows a significant increase of the self-discharge rate with temperature and pinpoints the underlying mechanisms; at lower initial voltages the self-discharge rate is dominated by diffusion of electrolyte ions rather than charge redistribution. Fourthly, the addition of a small amount of liquid crystals (LC) in neutral electrolyte shows a reduction of self-discharge and leakage current due to slower diffusion of ions in the device, which is proposed to originate from the anisotropic properties of LC. Finally, by utilizing the thermocapacitive effect, a thermal charging of ECs containing IL is demonstrated, where a high voltage of more than 900 mV could be recovered when two devices in series are exposed to a 60 °C temperature environment.

A major issue with all flow batteries is the control of the imbalance between the two half-cell electrolytes that arises as a result of the differential transfer of ions across the membrane and the inevitable gassing side reactions that can occur during charging. While a number of methods are available to rebalance electrolyte state of charge and restore capacity, reliable methods are needed to monitor the state-of-charge of each individual half-cell solution in order to determine the appropriate action to be taken by the battery control system. In this study different methods of state-of-charge monitoring have been considered for application in the All-Vanadium Redox Flow Battery (VRB). Half-cell potentials and electrolyte conductivities were calibrated as a function of state-of-charge and evaluated for state-of-charge monitoring of individual half-cell electrolytes for the purpose of capacity restoration and control. An empirical model based on experimental conductivity data has been shown to provide accurate predictions, with an average error of 0.77%, of the conductivity of the positive half-cell electrolyte as a potential state-of-charge detection tool. Separate monitoring of the two half-cell electrolyte potentials has also been used to determine the state-of-charge of each half-cell solution in order to detect system imbalance. This was used in small laboratory cell tests to determine necessary actions to restore capacity by either remixing the two solutions, or by using chemical rebalancing methods, depending on the cause of the solution imbalance.

In assessing the impact of global tourism on climate change, emissions from transport receive the most attention although emissions associated with accommodation account for more than 20% of the total. A plethora of hotel certification schemes have been established worldwide that assess various environmental performance indicators, among them energy use. However, none explicitly quantify CO2 emissions, and in many, energy is poorly accounted for, or other non-energy related factors are weighted so that the overall impact of energy use (and hence CO2 emission) is weak. The main thrust of the research is to ascertain the effect of certification on CO2 emissions. The research questions whether the certification schemes are robust and rigorous and whether the results are credible. First, four widely used certification schemes are compared Nordic Swan (Scandinavia), Green Globe (Worldwide), EU Flower (European) and Green Hospitality Award (Ireland). The key issues are identified such as performance and process related criteria, use of benchmarks, and the weighting of different categories. A comparison is made with LEED-EB, a well-established environmental certification scheme, not dedicated to the hotel sector. Secondly, the way in which emissions from electricity, including so-called green electricity and carbon offsetting, are accounted for is examined since it is found that in obtaining certification, this often plays an important part. Actual annual energy use data is desperately needed as feedback to designers, managers and owners in order to give confidence that certification schemes have true validity. Results are presented from large multi-hotel data samples and for detailed results from the quality, illustrative in-depth studies which provided invaluable insight into the technical realities of a multitude of causes and effects which can often be masked in large data samples. An analysis was carried out for four In-depth studies located in Sweden (Nordic Swan), Maldives (Green Globe), Malta (EU Flower) and Ireland (Green Hospitality Award). Global CO2 emissions were compared and calculated from the delivered electricity and fuels consumption data from seventy selected certified hotels worldwide. No corrections were made in the calculations for climate, quality of services, existence of services etc. The performance indicator used is kgCO2 per guest night. The analyses shows no clear pattern. CO2 emissions show a wide variance in performance for 8 hotels certified under different schemes, as well as for 28 hotels certified under the same scheme. In some cases emissions reduced after certification in others no change. Certified hotels do not necessarily have lower emissions than uncertified hotels and a comparison of before – and after – certification shows no significant improvement prior to certification. Most dramatically emissions from certified hotels widely vary by a factor of 7. Although it is arguable a number of corrections should be made to account for different climates, the research highlights that hotels with high CO2 emissions are being awarded certification and it questions what message‘certification’ gives to guests and other stakeholders. At worst it appears ‘business as usual’ can achieve certification with no obvious improvement in performance. The overall conclusion is that existing certification schemes do not properly account for CO2 emissions and do not produce more energy efficient (or less CO2 intensive) buildings. Hotel accommodation was found to be more CO2 intensive than domestic emissions. The findings also uncovered inconsistencies in current methods of certification and indicate a vital need for improved methods. The results also challenge prevailing aesthetic stereotypes of sustainable hotels. The author concludes a simple CO2 accounting method is needed as the first step of a diagnostic process leading to a solution i.e. reduced emissions, to the problem i.e. high energy consumption and/or emissions, thus reducing the environmental impact (in terms of emissions reduction) of the hotel. This method of accounting can be adopted universally by using a Regional, European (O.475 kgCO2/kWh) or Universal (0.55 kgCO2/kWh) conversion factor. In relation to the proper calculation of energy and CO2 emission, sub-metering is a key factor, and with current technological developments, realistic and affordable. Furthermore, apart from certification itself, an essential quality with any monitoring system is that the user can obtain results easily and understandably, in order to get feedback from their actions. This could be facilitated by incorporating sub-metering as part of the building environmental management system software. This ensures that the certification activity is not simply a benchmark, but is also part of a diagnostic and educational process, which will continue to drive emissions down. Only then should it be ethically justified to use as a marketing tool providing diagnostic support in existing buildings, and design and operational guidance for new designs.
