Marine renewables are technologies that generate electricity from tide and wave motion. They produce electricity without greenhouse gases, and could provide economic benefits for the UK. However, the technologies have been slow to develop, despite previous projections of growth. This POSTnote examines the causes of this delay and how the sector might develop.

This report outlines environment concerns. Greenhouse gas emissions seem to be falling during the outbreak. While experts note an opportunity to continue this reduction through policy-making, experts are concerned that the need to reinvigorate the economy will override environmental considerations. Access to green space has been important in supporting people’s well-being. Experts note that access to green space is limited in some urban areas. They have similar concerns for the equality of access to active travel such as cycling.

Evidence suggests that food fraud continues to be an issue in the global food supply chain. This POSTnote provides an overview of food fraud, including its drivers and impacts. It discusses methods for food authenticity testing, broader strategies to prevent food fraud and impacts of EU exit.

The UK’s flood risk from rivers, surface water and ground-water is projected to increase with climate change. Natural flood management (NFM) can be described as using the natural features of the land to store and slow down the flow of water. NFM is being piloted across the UK and its expansion is an objective of the Government’s 25 Year Environment Plan. This POSTnote examines the evidence for the effectiveness of NFM at reducing flood risk, and successful governance approaches to implementing NFM measures.

Over 1,100 experts have responded to a COVID-19 survey by POST's Knowledge Exchange Unit. Through the survey, experts shared their concerns about COVID-19 and COVID-impacted areas in the immediate and longer term future. Researchers have also shared what further data or information they would like to see the Government release to understand the decisions that underpin its approach. This first report outlines the survey methodology. Detailed reports with concerns on specific areas such as trade, education, and public health will be published in the coming days.
POSTnote
Key infrastructure areas such as transport, energy, water and telecoms are vital to society and the economy. Evidence suggests that climate change is increasing the frequency and severity of extreme weather events, posing a risk to infrastructure systems. This POSTnote looks at the main climate-related risks to the UK’s economic infrastructure, measures to reduce these risks and the main challenges to implementing resilience measures.
POSTbrief
This POSTbrief provides further information on the data limitations for understanding insect declines and emerging methods to address these limitations. Further detail is also given on the evidence for drivers of insect declines, such as disease or artificial light at night, which are summarised in POSTnote 619. The POSTbrief also highlights areas where evidence is established or where there are gaps in knowledge, such as insect abundance data.
POSTnote
Insects provide vital goods and services for wildlife, food production and human health, and their decline threatens important natural processes. Despite some insects being in long-term decline, a few species are showing stable or increasing trends. Insects can respond to interventions quickly. This POSTnote summarises the evidence for insect declines in the UK, the drivers of trends, and interventions to support the recovery of insect populations.

According to global climate and economic models, removing greenhouse gases from the atmosphere will be necessary to limit global warming to 1.5˚C. Among Greenhouse Gas Removal (GGR) techniques, these models assume that Bioenergy with Carbon Capture and Storage (BECCS) could play a prominent role. This POSTnote summarises why BECCS has been included in the models, outlines the challenges and trade-offs of deploying at scale, and considers policy options for supporting its development.
POSTnote
There is increasing consensus among scientists and commentators for addressing conservation and climate change issues together, particularly through the development of intergovernmental agreements and targets. This POSTnote summarises the links between biodiversity loss and climate change, and outlines options for jointly addressing their drivers and effects on a global scale.

This POSTnote reviews the main types of low-carbon aviation fuels and their potential for use, as well as associated challenges and opportunities. It supplements POSTnote 615: Climate Change and Aviation.
POSTnote
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.
POSTbrief
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.
