Question: What is the name of the policy for the development of national waste strategies shared by the Parliament of the United Kingdom as well as The Northern Ireland Executive?

Context paragraphs:
Devolution in the United Kingdom: In the United Kingdom, devolution (Scottish Gaelic: "fèin-riaghlaidh" , Welsh: "datganoli" ; Irish: Dílárú) refers to the statutory granting of powers from the Parliament of the United Kingdom to the Scottish Parliament, the National Assembly for Wales, the Northern Ireland Assembly and the London Assembly and to their associated executive bodies the Scottish Government, the Welsh Government, the Northern Ireland Executive and in England, the Greater London Authority and combined authorities.

Local government in Northern Ireland: Northern Ireland is divided into 11 districts for local government purposes.  In Northern Ireland, local councils do not carry out the same range of functions as those in the rest of the United Kingdom; for example they have no responsibility for education, road-building or housing (although they do nominate members to the advisory Northern Ireland Housing Council).  Their functions include waste and recycling services, leisure and community services, building control and local economic and cultural development.  They are not planning authorities, but are consulted on some planning applications.  The collection of rates is handled centrally by the Land and Property Services agency of the Northern Ireland Executive.

National Waste Strategy: The National Waste Strategy is a policy of the Parliament of the United Kingdom as well as the devolved administrations in Scotland, Wales and Northern Ireland.  The development of national waste strategies is intended to foster a move to sustainability in waste management within the United Kingdom.

Health and Social Care in Northern Ireland: Health and Social Care in Northern Ireland (HSC) is the designation of the publicly funded service which provides public health and other social care services in Northern Ireland.  The Northern Ireland Executive through its Department of Health is responsible for its funding, while the Public Health Agency is the executive agency responsible for the provision of health and social care services across Northern Ireland.  It is free of charge to all citizens of Northern Ireland and the rest of the United Kingdom.  For services such as A&E, patients simply walk in, state their name and date of birth, are given treatment and then leave.  Patients are unaware of costs incurred by them using the service.  It is sometimes called the "NHS", as in England, Scotland and Wales, but differs from the NHS in England and Wales in that it provides not only health care but social care too (the NHS in Scotland also includes social care).  Social services are provided by local councils.  The Health and Social Care service was created by the Parliament of Northern Ireland in 1948 after the Beveridge Report.

Department of Justice (Northern Ireland): The Department of Justice is a devolved Northern Ireland government department in the Northern Ireland Executive.  The current Minister of Justice is Claire Sugden, who is a member of the Northern Ireland Executive.  The department was established on 12 April 2010 as part of the devolution of justice matters to the Northern Ireland Assembly.

Politics of Northern Ireland: Since 1998, Northern Ireland has devolved government within the United Kingdom.  The government and Parliament of the United Kingdom are responsible for reserved and excepted matters.  Reserved matters are a list of policy area (such as civil aviation, units of measurement, and human genetics), which the Westminster Parliament may devolve to the Northern Ireland Assembly at some time in future.  Excepted matters (such as international relations, taxation and elections) are never expected to be considered for devolution.  On all other matters, the Northern Ireland Executive together with the 108-member Northern Ireland Assembly may legislate and govern for Northern Ireland.  Additionally, devolution in Northern Ireland is dependent upon participation by members of the Northern Ireland Executive in the North/South Ministerial Council, which co-ordinates areas of co-operation (such as agriculture, education and health) between Northern Ireland and the Republic of Ireland.

Politics of the United Kingdom: The United Kingdom is a unitary state with devolution, is governed within the framework of a parliamentary democracy under a constitutional monarchy, in which the monarch, currently Queen Elizabeth II, is the head of state and the prime minister of the United Kingdom, currently Theresa May, is the head of government.  Executive power is exercised by the British government, on behalf of and by the consent of the monarch, as well as by the devolved governments of Scotland and Wales, and the Northern Ireland Executive.  Legislative power is vested in the two chambers of the Parliament of the United Kingdom, the House of Commons and the House of Lords, as well as in the Scottish parliament and Welsh and Northern Ireland assemblies.  The judiciary is independent of the executive and the legislature.  The highest court is the Supreme Court of the United Kingdom.

Northern Ireland Assembly: The Northern Ireland Assembly (Irish: "Tionól Thuaisceart Éireann" , Ulster-Scots: "Norlin Airlan Assemblie") is the devolved legislature of Northern Ireland.  It has power to legislate in a wide range of areas that are not explicitly reserved to the Parliament of the United Kingdom, and to appoint the Northern Ireland Executive.  It sits at Parliament Buildings at Stormont in Belfast.

Northern Ireland Executive: The Northern Ireland Executive is the devolved government of Northern Ireland, an administrative branch of the legislature Northern Ireland Assembly.  It is answerable to the Assembly and was established according to the terms of the Northern Ireland Act 1998, which followed the Good Friday Agreement (or Belfast Agreement).  The executive is referred to in the legislation as the Executive Committee of the Assembly and is an example of a consociationalist government.

Separation of powers in the United Kingdom: The conception of the separation of powers has been applied to the United Kingdom and the nature of its executive (UK government, Scottish Government, Welsh Government and Northern Ireland Executive), judicial (England and Wales, Scotland and Northern Ireland) and legislative (UK Parliament, Scottish Parliament, National Assembly for Wales and Northern Ireland Assembly) functions.  Historically, the apparent merger of the executive and the legislature, with a powerful Prime Minister drawn from the largest party in parliament and usually with a safe majority, led theorists to contend that the separation of powers is not applicable to the United Kingdom.  However, in recent years it does seem to have been adopted as a necessary part of the UK constitution.
