Aviation has a growing impact on climate change, as demand for air travel increases globally. This POSTnote examines options for mitigating greenhouse gas (GHG) emissions from aviation, including new technologies, demand reduction and emissions offsetting. It also outlines UK and global policy frameworks for implementing measures to do so. 

Under the July 2018 revision of the National Planning Policy Framework, the government requires local authorities in England to embed relevant strategies into local plans to deliver a net environmental gain over possible reductions caused by developments and infrastructure. The initial objective of this requirement will be to deliver gains in levels of biodiversity – short for biological diversity, the abundance and variety of species and their physical habitats – at the landscape level. In December 2018, Defra launched a consultation on implementing a mandatory biodiversity net gain requirement for development in England.

Critical materials (CMs) are key to UK manufacturing, including for the aerospace, automotive, energy and chemical sectors, which rely on materials typically extracted and processed abroad. CMs are vital components of several emerging technologies, including electric vehicles, renewable energy infrastructure such as wind turbines, and digital technologies such as computers and smartphones. The UK imports most of its CMs and faces international competition for key resources. This POSTnote looks at the demand and supply of CMs in the UK and ways of improving supply security.

    This document builds on POST's previous publication, Topics of Interest 2018 (POSTbrief 27). The subjects are listed under under six category headings based on the drivers of change identified in POSTnote 500: demographic change and healthcare; social and cultural trends; geopolitical and governance challenges; environmental pressures and climate change; resource security and sustainability; and technological advance.

    Fishing is dependent on marine food webs that are sensitive to overexploitation and climate change. This POSTnote focuses on marine fisheries, including wild capture and farming (aquaculture) of fin- and shellfish, and their processing. It summarises impacts on oceans and fisheries of changes including ocean warming, acidification, deoxygenation and storms, and explores how fisheries may adapt.

    Wildfire is any uncontrolled vegetation fire that requires a decision, or action, to suppress it. This POSTnote summarises management of wildfires in the UK, how projected climate changes may affect UK wildfire behaviour, and the environmental, economic, and health impacts of this. It also outlines policy options for increasing the UK’s resilience to wildfires.

    UK power generation from wind has increased in recent years due to sharp reductions in the costs of constructing and operating wind power facilities. Onshore wind power provides the cheapest electricity of any form of new generation built, and offshore is expected to continue to reduce in cost. Generating wind power does not emit greenhouse gases, hence future growth will help the UK meet its GHG emissions reduction targets. This POSTnote examines the innovations that have enabled wind power cost reductions, associated policy considerations and challenges for future deployment.

    The soil microbiome, communities of microorganisms in soils, underpin natural processes in soil habitats and are affected by environmental and land use change. This POSTnote gives an overview of the benefits provided by the soil microbiome, ways of assessing the soil microbiome, and measures to improve its condition.

    Agriculture is highly vulnerable to climate change impacts, which has implications for food security. This POSTnote examines measures to reduce the impacts of food production and agricultural land use on climate change (mitigation) and to adapt agricultural land use to that change (adaptation).

    Despite its relatively temperate climate and stable geography, natural hazards present multiple risks to human activity in the UK. These range from small-scale local occurrences, such as landslides, through regional incidents, such as flooding, to major high impact, low probability events, such as space weather. The impacts of such hazards can be wide-ranging but may include disruption to critical infrastructure and transport networks, detrimental effects on human welfare, and, in some cases, loss of life. This POSTbrief summarises the emergency planning for such hazards undertaken by Civil Contingencies Secretariat (CCS) of the Cabinet Office and published in the classified National Risk Assessment (NRA) and unclassified National Risk Register (NRR).

    The widespread use of antimicrobials, particularly antibiotics, has accelerated the spread of antimicrobial resistance (AMR) in microbes. A recent report by the Health and Social Care Committee called for AMR to be a ‘top five policy priority’. This POSTnote evaluates the main reservoirs of AMR microbes arising from the use of antimicrobials in both humans and animals.

    Under the Paris Agreement, almost all governments worldwide have agreed to collectively limit global warming to 'well below' 2°C above pre-industrial temperatures, and to 'pursue efforts' to limit this warming to 1.5°C. However, there has been 1°C of warming to date, and current international pledges could result in 3°C or more. A 2018 UN Special Report examined how peak global warming could be limited to 1.5°C above pre-industrial temperatures, and the implications of doing so. This POSTnote outlines key messages from the UN Special Report, and UK responses to preventing and adapting to climate change.
