    Invasive non-native species

    Research suggests that the threat from invasive non-native species (INNS) is growing. Biological invasions by INNS harm native species and habitats and can have economic impacts. Biosecurity measures can be adopted to prevent the introduction and spread of INNS. This POSTnote summarises the drivers and impacts of INNS and the measures needed to meet national and international environmental targets.

    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.

    Geothermal energy

    Geothermal energy is a source of low-carbon, homegrown, renewable energy. It is available throughout the UK and can provide heat or power all year long independent of weather conditions. It currently delivers less than 0.3% of the UK’s annual heat demand, using only a fraction of the estimated available geothermal heat resource. There is the potential to increase this proportion significantly, but this will require long-term government support to develop a route to market and overcome high upfront capital costs and geological development risks.

    Reducing peatland emissions

    Peat soils store greenhouse gases for millennia if they stay waterlogged. However, an estimated 5% of global greenhouse gas emissions are released from peat soils due to their modification by humans. Reducing these emissions will help meet climate targets, with objectives to achieve this set out in action plans by the governments of the UK. This POSTnote describes the pressures on peat soils and summarises the challenges for reducing emissions from English peatlands.

    Financial risks of nature loss

    Nature loss poses risks to the financial sector via the businesses they invest in, lend to, advise and insure. The financial risks of nature loss are embedded within the financial systems but are little understood or addressed by financial institutions. The POSTnote will outline the current understanding of the type and scale of the financial risks of nature loss and look at potential mechanisms to improve company level reporting and mitigation of both the financial risks of nature loss, and nature loss itself.

    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.

    Preventing emerging zoonoses

    Zoonoses are diseases that can be transmitted between animals and humans. This POSTnote summarises approaches to preventing zoonoses with pandemic potential by targeting animal-environment-human interactions. It reviews current biosecurity measures in the UK and globally, notes lessons from COVID-19 and identifies future strategies.

    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.
