    Abstract Poverty impacts people’s choices and opportunities and can perpetuate a disadvantaged status. Poverty remains a prevalent global issue due to disproportionate wealth distribution, which often translates to inequality in energy consumption and emissions. This research investigates if low-income households and minorities from four countries with very different national cultures, contexts, and levels of wealth experience a ‘double energy vulnerability’, a concept that simultaneously positions people at heightened risk of transport and energy poverty. Our research identifies that low-income households and minorities are at higher risk of simultaneously experiencing energy and transport poverty regardless of the national context in which they live. Our study also contests the achievement of Sustainable Development Goals (SDGs) by 2030, showing that even in relatively wealthy countries, many individuals still face energy and transport poverty. We conclude that global sustainable development requires significant shifts in policy action, resource distribution and investment in social services

    Decarbonizing the glass industry: a critical and systematic review of developments, sociotechnical systems and policy options

    Glass is a material inextricably linked with human civilization. It is also the product of an energy intensive industry. About 75%–85% of the total energy requirements to produce glass occur when the raw materials are heated in a furnace to more than 1500 °C. During this process, large volumes of emissions arise. The container and flat glass industries, which combined account for 80% of total glass production, emit over 60 million tonne of CO2 per year. However, environmental issues relating to the glass industry are not just limited to the manufacturing stage, but also from raw materials extraction, which impacts local ecosystems and creates other environmental challenges associated with tailing ponds, waste disposal and landfills. This systematic review poses five questions to examine these issues and themes: What alternatives exist to abate the climate effects of glass and thus make the full life cycle of glass more sustainable? What are the key determinants of energy and carbon from glass? What technical innovations have been identified to make glass manufacturing low to zero carbon? What benefits will amass from more carbon-friendly process in glass manufacturing, and what barriers will need tackling? To examine these questions, this study presents the findings of a comprehensive and critical systematic review of 701 studies (and a shorter sample of 375 studies examined in depth). A sociotechnical lens is used to assess glass manufacturing and use across multiple sectors (including buildings, automotive manufacturing, construction, electronics, and renewable energy), and options to decarbonize. The study identifies a number of barriers ranging from financial to infrastructural capacity, along with high potential avenues for future research

    Decarbonizing the ceramics industry: a systematic and critical review of policy options, developments and sociotechnical systems

    Ceramics are considered one of the greatest and earliest most useful successes of humankind. However, ceramics can be highly damaging to natural and social systems during their lifecycle, from material extraction to waste handling. For example, each year in the EU, the manufacture of ceramics (e.g., refractories, wall and floor tiles and bricks and roof tile) emit 19 Mt CO2, while globally, bricks manufacturing is responsible for 2.7% of carbon emissions annually. This critical and systematic review seeks to identify alternatives to mitigate the climate effects of ceramics products and processes to make their lifecycle more sustainable. This article reviews 324 studies to answer the following questions: what are the main determinants of energy and carbon emissions emerging from the ceramics industry? What benefits will this industry amass from adopting more low-carbon processes in manufacturing their products, and what barriers will need to be tackled? We employ a sociotechnical approach to answer these questions, identify barriers to decarbonise the ceramics industry, and present promising avenues for future research. In doing so, we show that environmental and energy challenges associated with the ceramics industry are not just limited to the manufacturing stage but also relate to the extraction of raw materials, waste disposal, and landfilling

    Global energy use has grown with the advance of human civilization such that we now use approximately 175,000 TWh of energy per year. This demand for energy provides essential services, from lighting homes to producing heat for industrial processes. Human demand for energy in the coming decades is highly uncertain. Climate change, the consequent necessity for decarbonization, and the many possible technology and policy pathways to net zero emissions (or not) mean there are many possible futures for energy demand. Regardless of this uncertainty, change in the energy sector is happening already, with greater change to come. In this article we discuss fuels and energy carriers, energy sectors and end uses, emerging energy vectors and new technologies, and lastly the cross linking of energy sectors and vectors
