    Green steel

    Greenhouse gas (GHG) emissions from the iron and steel industry make up 14% of industrial emissions in the UK. Decarbonisation of the steel industry is needed if the UK is to meet its target of net zero GHG emissions by 2050. This POSTnote outlines current steelmaking processes in the UK, the technologies and measures that can be used to reduce CO2 emissions, and the supporting infrastructure and policies that could enable a ‘green steel’ industry in the UK.

    Mining and the sustainability of metals

    The mining and processing of minerals underpins modern technology and infrastructure. Each year, over 3.3 billion tonnes of metals are produced globally, and most predictions of demand show increasing consumption of metals in the coming decades, including in renewable energy generation, electric vehicles and batteries. The transition of the world’s economies and industries to more sustainable energy and technologies will require more mining and processing of non-renewable mineral resources, with associated positive and negative impacts on the environment and society.

    International shipping and emissions

    International shipping is widely regarded as a ‘difficult-to-decarbonise’ sector. However, having been included in the UK Government’s sixth carbon budget, rapid reductions in emissions from this sector will be required to contribute to UK’s goal of net zero greenhouse gas emissions by 2050. This POSTnote examines the options for reducing emissions from international shipping activities and outlines the regulatory landscape of the sector.

    Restoring agricultural soils

    Changes to the management of agricultural soil could contribute to improving the ability of soils to produce crops, as well as to wider benefits including mitigating future climate change. This POSTnote summarises the state of England’s agricultural soils and evaluates soil stewardship opportunities. Soil indicators that could be used for monitoring in policy frameworks and incentives relating to soil restoration are explored.

    Reducing agricultural pressures on freshwater ecosystems

    Freshwater ecosystems in the UK face a myriad of pressures, with agricultural activities a leading source of impacts. Defra’s Agricultural Transition Plan proposes a “systems” approach to mitigate environmental pressures. This POSTnote first describes the components of UK freshwater catchments, then summarises opportunities for developing a more integrated approach to addressing the pressures that agricultural practices place on freshwaters.

    Sustainable land management: managing land better for environmental benefits

    England is at a historical crossroad for the governance of land and the natural environment. Actions for addressing and adapting to climate change, achieving food security and tackling the biodiversity crisis are all embedded in and depend on how land is managed. Existing Government policy and targets have so far failed to address many of these complexities of land, farming and the natural environment.

    Smart Cities

    "Smart cities" describes places that incorporate a range of technologies (especially those that collect and use data) to address economic, social, and environmental challenges. Projects usually take place in urban areas, but are also deployed in rural settings. This POSTnote looks at smart city innovation in the UK and the technologies involved. It considers the factors driving the adoption of smart city technologies, and the potential benefits, barriers and risks associated with their implementation.

    Defence of space-based assets

    Space-based assets (satellites and the terrestrial ground stations that communicate with them) provide critical support to military and civilian operations. They are vulnerable to unintentional damage and disruption, and to deliberate attack. This POSTnote outlines how the UK uses and accesses satellites, potential risks to satellites, and approaches to mitigation.

    Environmental housing standards

    Buildings have varied impacts on the environment, arising from energy, water and land use as well as the release of pollutants. Residential buildings also affect occupants’ health and wellbeing through their design and placement within the wider environment. This POSTnote summarises the factors affecting a building’s environmental performance, the existing governance framework and the potential opportunities for delivering wider social benefits through relevant standards.

    Coastal management

    The UK coastline is shaped by interactions between complex social, ecological, and physical processes. Increasing coastal flood and erosion risk is a major climate adaptation challenge. This POSTnote examines coastal management in England, associated issues and how an adaptive approach can better prepare the country for uncertain future sea level rise under climate change.

    Regulating product sustainability

    Products can be designed to maximise life cycle energy- and resource-efficiency, from raw material extraction to end-of-life treatment. This POSTnote outlines key aspects of, and consumer attitudes towards, sustainable products. It considers challenges associated with their design, production, regulation and supporting business models as part of a circular economy. ‘End-of-life’ treatment and value recovery, through reuse, recycling and other methods, are discussed.

    Low-carbon hydrogen supply

    Hydrogen could play a significant role in tackling climate change. Using it does not produce carbon dioxide, so it could replace fossil fuels in a range of applications. It may also provide valuable energy storage. However, almost all hydrogen production currently results in greenhouse gas emissions. Methods of producing it that do not emit greenhouse gases would need to increase for it to contribute to climate change mitigation. Governments and industry in the UK and abroad are aiming to increase low-carbon hydrogen supply. The UK Government will publish a Hydrogen Strategy in 2021.

    Developing essential digital skills

    Digital skills are increasingly important for day-to-day life, including for communication, accessing services and employment. However, around a fifth of the population do not have essential digital skills for life as defined by the UK Government. While research suggests the number of people with basic digital skills has increased in recent years, concerns remain about those who lack them. Experts have highlighted that digitally excluded people may experience various negative impacts, including poorer health outcomes and social isolation This POSTnote gives an overview of digital skills in the UK, the impact of a lack of digital skills on outcomes in areas such as employment and health, and initiatives in place to improve digital skills.
