Energy transition has become a priority for adaptive policy and measures taken in response to climate change around the world. This is an opportunity and a challenge for the Taiwan government to establish a climate-resilient power generation mixed to ensure electricity security as well as climate change mitigation. This study adopted a sustainable development perspective and applied optimal control theory to establish a cost-effective model to evaluate a long-term (2050), climate-resilient power generation mix for Taiwan. Furthermore, this study applies the STIRPAT approach to predict the demand of electricity by 2050 for the demand side management. The results not only showed the share of various power generation mixed, but also recommended the trajectory of electricity saving by 2050.

Climate change can cause serious problems for future hydropower plant projects and make them less economically justified. Changing precipitation patterns, rising temperatures, and abrupt snow melting affect river stream patterns and hydropower generation. Thus, study of climate change impacts during the useful life of a hydropower dam is essential and its outcome should be considered in assessing long-term dam feasibility. The aim of this research is to evaluate the impacts of climate change on future hydropower generation in the Karun-III dam located in the southwest region of Iran in two future tri-decadal periods: near (2020–2049) and far (2070–2099). Had-CM3 general circulation model predictions under A2 and B2 SRES scenarios were applied, and downscaled by a statistical downscaling model (SDSM). An artificial neural network (ANN) and HEC-ResSim reservoir model respectively simulated the rainfall–runoff process and hydropower generation. The projections showed that the Karun-III dam catchment under the two scenarios will generally become warmer and wetter with a slightly larger increase in annual precipitation in the near than the far future. Runoff followed the precipitation trend by increasing in both periods. The runoff peak also switched from April to March in both scenarios, due to higher winter precipitation, and earlier snowmelt, which was caused by temperature rise. According to both scenarios, hydropower generation increased more in the near future than in the far future. Annual average power generation increased gradually by 26.7–40.5% under A2 and by 17.4–29.3% under B2 in 2020–2049. In the far period, average power generation increased by 1.8–8.7% in A2 and by 10.5–22% under B2. In the near future, A2 showed energy deduction in the months of June and July, while B2 revealed a decrease in the months of April and June. Additionally, projections in the 2070–2099 under A2 exhibited energy reduction in the months of March through July, while B2 revealed a decrease in April through July. The framework utilized in this study can be exploited to analyze the susceptibility of hydropower production in the long term.

Two aspects of the development trend of current nuclear fission technology are discussed. The first aspect is to improve economic competitiveness and safety for searching opportunity of enlarging the share of nuclear power. The second aspect is to explore new ways of improving the efficiency of nuclear fuel utilization and of reducing the geological repository volume of radioactive products from nuclear power generation. Sustainable development of Chinese economy in 21st century will mainly rely on sustainable supply of clean energy with indigenous natural resources. The burden of current coal-dominant energy mix and the environmental pollution due to energy consumptions has led nuclear power to be an indispensable choice for further expanding electricity generation capacity and for reducing greenhouse effect gases emission in China. The long-term sustainable development strategy with nuclear fission technology beyond generation-IV for electric power generation, namely the fusion-fission hybrid subcritical reactor technology, is discussed. The impact of the proposed fission-fusion hybrid reactor to future nuclear power generation technology will reply on the success of the ITER-scale (500MW fusion power) Tokamak to burn plasma continuously in the predictable future. The main challenges and prospects of the strategy are also analyzed. The preliminary analysis has shown that the fission in the subcritical blanket driven by fusion neutrons can effectively amplify the energy carried by fusion neutron and maintain breeding of fissile material and tritium. It has been found from the results of a conceptual design that this new type of fusion-fission hybrid reactor may meet the requirement of China’s long-term sustainable development of nuclear energy.

Great Energy

On 4 November 2016, the historic Paris Climate Agreement of the United Nations entered into force, requiring signatory countries to maintain global warming at the level of 1.5–2 °C. According to the calculations of the Intergovernmental Panel on Climate Change (IPCC), to achieve this goal, a 2/3 reduction in greenhouse gas energy emissions into the atmosphere compared with gaseous energy-related emissions in 2019 (33.3 Gt) by about 2050 (1.5 °C) or by 2070 (2 °C) is required. According to the International Renewable Energy Agency (IRENA), this is only possible with the implementation of a great energy transition from the use of currently dominant fossil hydrocarbon fuels—coal, oil, and natural gas—to the predominant use of renewable energy sources (RES) by 2040–2050, when the share of renewable energy in the total energy balance will reach 40% and above. In this work, mathematical description of an upcoming energy transition has been carried out, including long-term scenario writing of the world’s demographic dynamics and global energy demand, calculation of the dynamics of industrial CO2 emissions and CO2 accumulation in the Earth’s atmosphere, as well as the corresponding changes in the average global temperature of the Earth’s surface in the 21st century. A mathematical description of the impact of energy consumption on climate change was carried out taking into account long-term trends in the dynamics of energy consumption. Using the performed mathematically-oriented scenario writing, it is suggested that a great energy transition with the achievement of the goals of the Paris Agreement is possible only by 2060. Renewable energy could sufficiently displace and replace hydrocarbon fuels to achieve climate safety without compromising economic development. As a result, humanity will receive an environmentally friendly decentralized distributed energy system, connected by «smart» grids, controlled by intelligent digital technologies.

Risk Reporting

Purpose This paper aims to evaluate non-financial reporting (NFR) frameworks insofar as risk reporting is concerned. This is facilitated through analysis of the adequacy of climate- and pandemic-related risk reporting in three industries that are both significantly impacted by the COVID-19 pandemic and are at risk from climate change. The pervasiveness of pandemic and climate-change risks have been highlighted in 2020, the hottest year on record and the year the COVID-19 pandemic struck. Stakeholders might reasonably expect reporting on these risks to have prepared them for the consequences. Design/methodology/approach The current debate on the “complexity” of sustainability and NFR frameworks/standards is critically analysed in light of the COVID-19 pandemic and calls to “build back better”. Context is provided through analysis of risk reporting by the ten largest airlines and the five largest companies in each of the hotel and cruise industries. Findings Risk reporting on two significant issues, pandemics and climate change, is woefully inadequate. While very little consideration has been given to pandemic risks, disclosures on climate-related risks focus predominantly on “risks” of increased regulation rather than physical risks, indicating a short-term focus. The disclosures are dispersed across different corporate reporting media and fail to appreciate the long-term consequences or offer solutions. Mindful that a conceptual framework for NFR must address this, the authors propose a new definition of materiality and recommend that sustainable development risks and opportunities be placed at the core of a future framework for connected/integrated reporting. Research limitations/implications For sustainable development risks to be perceived as “real” by managers, further research is needed to determine the nature and extent of key sustainable development risks and the most effective mitigation strategies. Social implications This paper highlights the importance of recognising the complexity of the issues facing organisations, society and the planet and addressing them by encouraging robust consideration of the interdependencies in evolving approaches to corporate reporting. Originality/value This study contributes to the current debate on the future of corporate reporting in light of two significant interconnected crises that threaten business and society – the pandemic and climate change. It provides evidence to support a long-term oriented and holistic approach to risk management and reporting.

Weather Stations

Monitoring climate change, and its impacts on ecological, agricultural, and other societal systems, is often based on temperature data derived from official weather stations. Yet, these data do not capture most microclimates, influenced by soil, vegetation and topography, operating at spatial scales relevant to the majority of organisms on Earth. Detecting and attributing climate change impacts with confidence and certainty will only be possible by a better quantification of temperature changes in forests, croplands, mountains, shrublands, and other remote habitats. There is an urgent need for a novel, miniature and simple device filling the gap between low-cost devices with manual data download (no instantaneous data) and high-end, expensive weather stations with real-time data access. Here, we develop an integrative real-time monitoring system for microclimate measurements: MIRRA (Microclimate Instrument for Real-time Remote Applications) to tackle this problem. The goal of this platform is the design of a miniature and simple instrument for near instantaneous, long-term and remote measurements of microclimates. To that end, we optimised power consumption and transfer data using a cellular uplink. MIRRA is modular, enabling the use of different sensors (e.g., air and soil temperature, soil moisture and radiation) depending upon the application, and uses an innovative node system highly suitable for remote locations. Data from separate sensor modules are wirelessly sent to a gateway, thus avoiding the drawbacks of cables. With this sensor technology for the long-term, low-cost, real-time and remote sensing of microclimates, we lay the foundation and open a wide range of possibilities to map microclimates in different ecosystems, feeding a next generation of models. MIRRA is, however, not limited to microclimate monitoring thanks to its modular and wireless design. Within limits, it is suitable or any application requiring real-time data logging of power-efficient sensors over long periods of time. We compare the performance of this system to a reference system in real-world conditions in the field, indicating excellent correlation with data collected by established data loggers. This proof-of-concept forms an important foundation to creating the next version of MIRRA, fit for large scale deployment and possible commercialisation. In conclusion, we developed a novel wireless cost-effective sensor system for microclimates.

AbstractThe Sustainable Development Goals (SDGs) were adopted by the United Nations in 2015 as part of the “2030 Agenda for Sustainable Development” and aim to address issues ranging from poverty and economic growth to climate change. Efforts to tackle one issue can support or hinder progress towards others, often with complex systemic interactions. Thus, each of the SDGs and their corresponding targets may contribute as levers or hurdles towards achieving other SDGs and targets. Based on SDG indicator data, we create a systems model considering influence among the SDGs and their targets. Once assessed within a system, we find that more SDGs and their corresponding targets act as levers towards achieving other goals and targets rather than as hurdles. In particular, efforts towards SDGs 5 (Gender Equality) and 17 (Partnerships for the Goals) may accelerate progress, while SDGs 10 (Reduced Inequalities) and 16 (Peace, Justice and Strong Institutions) are shown to create potential hurdles. The model results can be used to help promote supportive interactions and overcome hindering ones in the long term.

The Impact

Climate change is an unprecedented challenge in human history. It requires further immediate and concerted action. Understanding the stage of development of each energy resource, as the impact on the energy system to make informed decisions and prescribe a healthy energy future has thus become a priority. Decisions such as the phasing out of fossil fuels and the transition to an efficient and 100% renewable energy system, as well as increasing the storage capacity of greenhouse gases using environmentally sustainable approaches, maintaining natural ecosystems that generate environmental services, and restoring the degraded ones are now a top issue. Therefore, the relationship between energy and environmental policy is becoming essential. Accordingly, this paper will focus on the transition to renewable energy, the adaptation to climate change and the energy transition at EU level being strenuously debated, in order to build a holistic context of the actual situation. Adaptation to climate change requests a complex scientific study, given the diversity of uncertainties involved, and the interconnections between different areas, such as agriculture, sustainable development or energy industry. Therefore, the aim of research is to provide holistic understanding of the current climate issues, according to the mentioned fields. In this context, it is emphasized the benefits of clean energy by investigating the methods for achieving a prolific energy transition, from a conventional to a sustainable one. Carefully analysing the commitments and the transition to a low-carbon electricity system looking behind the causes and studying closely the underlying elements of all these topics, using the qualitative research method as a basis to indulge in further analysis and research, it was outlined a detailed analysis of the current climate context. In conclusion, the effect of the pressure brought into play by human exploitation of goods and services on the ecosystems was associated with the ongoing concerns of environmental degradation, climatic variations, natural and ecological distortions, and financial setbacks. Taking into account the drive toward accomplishing sustainable development and environmental quality, powerful policies are being implemented, but given the variety of investment conditions in each country and including the different characteristics of the financial markets, there is no unique solution that works for everybody. Therefore, the transition to a more sustainable energy system has a verity of implications but it is an essential condition for sustainable development.

Abstract The aim of this article is a comprehensive review of Papal Encyclicals in the context of global environmental and climatic change, against the backdrop of the activity of multinational institutions. The Encyclicals look to the future in teaching the faithful, in a manner which indicates that they are part of a goal-oriented policy, both in terms of scientific research, and concrete economic, social, and geopolitical activity. Attention has also been paid to the relationship between the activity of humankind, and global environmental change, particularly of the biotic and climatic variety. If this aggressive anthropogenic activity cannot be deemed responsible for initiating global warming, it may certainly be seen to have “encouraged” it. The impulses behind sustainable development, as well as the instruments of its implementation, and the inspiration behind the idea, have also been discussed. The achievement of this goal, necessitating the balancing of anthropological aspirations and the long-term security of the environment are also referenced in the Encyclicals.

The importance and necessity of long-term field experiments lie in the fact that long-term effects can only be studied reliably over several decades. The agronomic advances made in recent decades, based on chemicals and genetic gains, can be measured using long-term data, which will also be important in the future. Nutrient balances can be estimated reliably from the results of these experiments. The effect of climate change can be estimated by comparing long-term data from different locations. Long-term databases also form the background for computer models, designed to promote the sustainable development of agriculture and the environment.
