"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.

Chemical Weapons (493 KB , PDF)
‘Chemical weapons’ refers to the use of toxic chemicals to inflict deliberate harm to humans or animals. They are prohibited by the Chemical Weapons Convention (CWC), which entered into force in 1997 and has been committed to by 193 states. The Organisation for the Prohibition of Chemical Weapons (OPCW) is the international body responsible for implementing the CWC. This includes: verifying the destruction of chemical weapons stockpiles, monitoring certain chemicals and carrying out investigations into alleged chemical weapons attacks.
There have been several reports of chemical weapons attacks in recent years. A Human Rights Watch analysis identified 85 attacks in Syria between August 2013 and February 2018. Joint OPCW-UN investigations in Syria attributed four chemical weapons attacks to the Syrian Government, and two to Daesh. Other incidents include the reported use of chemical weapons in Iraq by Daesh, and the alleged assassination of Kim Jong-nam using the nerve agent VX. In the UK in 2018, four people were taken seriously ill and one person died following exposure to a Novichok, a type of nerve agent.
The international response to events in Syria has included airstrikes on chemical weapons facilities in Syria, official OPCW investigations and a new mechanism to give the OPCW powers to attribute responsibility for chemical weapons use. In the UK, the Government announced a £48m investment in the Chemical Weapons Defence Centre at Porton Down in March 2018, which will include new chemical analysis laboratories. It also announced £11m to strengthen the UK’s response to chemical weapons attacks in March 2019, which will include investment in new technical capabilities for substance analysis and development of plans to deploy robots and drones to contaminated areas. The UK Government’s Modernising Defence Programme, published in December 2018, said that UK defence will focus on chemical, biological, radiological and nuclear (CBRN) threats.
- A chemical weapons system is made up of several components – a chemical warfare agent, a delivery device and any associated equipment (for example, dispersal equipment). Under the CWC, all these components are considered a chemical weapon if they are intended to cause harm to humans or animals.
- Many toxic chemicals and precursors are ‘dual-use’, meaning they have legitimate uses but could also be used as weapons. For example, chlorine is used in water purification but could also be used as a choking agent.
- Chemical weapons attacks can take different forms depending on the capability and the aims of those carrying them out.
- Policymakers and experts, including the OPCW, have expressed concern over terrorists’ interest in the use of chemical weapons.
- The OPCW oversees the destruction of chemical weapons stockpiles, carries out inspections and investigates alleged chemical weapons attacks.
- The UK has led a joint initiative to grant the OPCW powers to attribute responsibility for chemical weapons attacks. Some states are opposed to this move, with concerns it may compromise the politically neutral role of the OPCW.
- Chemical defence in the UK involves measures to prevent, prepare for, respond to, and recover from a chemical weapons attack.
- The UK response to a chemical incident involves many agencies working to treat victims, detect and identify hazardous materials, minimise impacts and support investigations.

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.
A POSTnote describing the impact of the COVID-19 pandemic on children's mental health. This briefing summarises the latest understanding from research about the effects on children throughout the pandemic, and the factors that increase vulnerability to poor mental health. It also reviews policy approaches that seek to protect children's mental health, with particular focus on recent initiatives to address this.
