an average of 90 million people in 80 nations each year. The Office of the United Nations High Commissioner for Refugees (UNHCR), established in 1950, works to protect the rights of refugees, asylum seekers, and stateless people. UNHCR and WFP programmes are funded by voluntary contributions from governments, corporations, and individuals, though the UNHCR's administrative costs are paid for by the UN's primary budget. Environment and climate Beginning with the formation of the UN Environmental Programme (UNEP) in 1972, the UN has made environmental issues a prominent part of its agenda. A lack of success in the first two decades of UN work in this area led to the 1992 Earth Summit in Rio de Janeiro, Brazil, which sought to give new impetus to these efforts. In 1988, the UNEP and the World Meteorological Organization (WMO), another UN organization, established the Intergovernmental Panel on Climate Change, which assesses and reports on research on global warming. The UN-sponsored Kyoto Protocol, signed in 1997, set legally binding emissions reduction targets for ratifying states. Other global issues Since the UN's creation, over 80 colonies have attained independence. The General Assembly adopted the Declaration on the Granting of Independence to Colonial Countries and Peoples in 1960 with no votes against but abstentions from all major colonial powers. The UN works towards decolonization through groups including the UN Committee on Decolonization, created in 1962. The committee lists seventeen remaining "non-self-governing territories", the largest and most populous of which is Western Sahara. The UN also declares and co-ordinates international observances that bring awareness to issues of international interest or concern; examples include World Tuberculosis Day, Earth Day, and the International Year of Deserts and Desertification. Funding The UN budget for 2022 was $3.1 billion, not including additional resources donated by members, such as peacekeeping forces. The UN is financed from assessed and voluntary contributions from member states. The General Assembly approves the regular budget and determines the assessment for each member. This is broadly based on the relative capacity of each country to pay, as measured by its gross national income (GNI), with adjustments for external debt and low per capita income. The Assembly has established the principle that the UN should not be unduly dependent on any one member to finance its operations. Thus, there is a "ceiling" rate, setting the maximum amount that any member can be assessed for the regular budget. In December
