UNSD data collection in env. statistics UNSD/UNEP Questionnaire 2013 on Environment Statistics – being sent out in April and focuses on water and waste statistics ( Questionnaire 2013 on Environment Statistics – being sent out in April and focuses on water and waste statistics ( Water statistics – The tables cover renewable freshwater resources, freshwater abstraction and use, water supply industry, wastewater generation and treatment, and population connected to waste water treatment.Water statistics – The tables cover renewable freshwater resources, freshwater abstraction and use, water supply industry, wastewater generation and treatment, and population connected to waste water treatment. Waste statistics – The tables cover the generation of waste, the generation and treatment of hazardous waste, and the generation, collection, treatment, and composition of municipal waste.Waste statistics – The tables cover the generation of waste, the generation and treatment of hazardous waste, and the generation, collection, treatment, and composition of municipal waste.
