O Instituto Nacional de Estatística

A informação é um produto fundamental na vida dos cidadãos, na actividade das empresas, no funcionamento dos Estados. A informação estatística, em especial, é hoje uma forma de conhecimento necessária à assunção de uma cidadania plena, imprescindível na tomada das decisões que fazem surgir e progredir as empresas, essencial ao enquadramento das políticas com que se governam as nações.
O Instituto Nacional de Estatística, IP (INE) tem como missão produzir e divulgar informação estatística oficial de qualidade, promovendo a coordenação, o desenvolvimento e a divulgação da actividade estatística nacional.
A nossa missão é tanto mais exigente quanto sujeita a permanente evolução. Para se manter relevante, a informação estatística, enquanto retrato da realidade, tem de saber acompanhar as constantes mudanças a que essa realidade está sujeita, detectando novas necessidades, fazendo opções sobre o que, a cada momento, importa medir.
As operações estatísticas do Instituto são realizadas de acordo com padrões internacionalmente estabelecidos de forma a garantir a sua qualidade, sendo os seus resultados disponibilizados em simultâneo a toda a sociedade.
O INE delega em outras entidades nacionais parte da actividade estatística do País, assumindo o objectivo de promover a coordenação dessa actividade e de facilitar aos utilizadores o acesso a toda a informação produzida.

UNSD Environmental Indicators
Statistics on Water and Waste are based on official statistics that had been supplied by national statistical offices and/or ministries of environment (or equivalent institutions) in countries in response to the biennial UNSD/UNEP Questionnaire on Environment Statistics. They were complemented by data from the Food and Agriculture Organization of the United Nations (FAO) on water resources. Data on EU and OECD member and partner countries are from OECD and Eurostat.
Statistics on other themes listed below have been compiled from other international organizations. The themes and indicator tables were selected based on the current demands for international environmental statistics and the availability of internationally comparable data. In a few tables, UNSD has made additional calculations in order to derive certain indicators. However, generally no adjustments have been made to the values received from the source. UNSD is not responsible for the quality, completeness/availability, and validity of the data obtained from outside sources.
Environment statistics is still in an early stage of development in many countries, and data are often sparse. The indicators selected here are those of relatively good quality and geographic coverage. Information on data quality and comparability is given at the end of each table together with other important metadata.
