Energy Indicators for Sustainable Development: Guidelines and Methodologies International Atomic Energy Agency United Nations Department of Economic and Social Affairs International Energy Agency Eurostat European Environment Agency

ASSESSMENT OF DATA 
(a) Data Needed to Compile the Indicator: Data on the production of waste at 
source and on the quantities delivered to waste treatment and disposal facilities. 
(b) National and International Data Availability: In general, waste statistics are of 
very poor quality, and the share of solid waste from energy production may be 
difficult to obtain. Available data are scattered and consist of only rough estimates. In 
the European Union, data on industrial waste and on waste treatment facilities will be 
regularly collected with the implementation of the Waste Statistics Regulation. 
(c) Data Reference: Many waste disposal facilities charge by weight for the 
treatment and disposal of waste. Therefore, these quantities should be readily 
available. However, this may not be all the waste treated, as some waste will be 
treated and disposed of on-site, without the intervention of outside contractors.

ENV9: Ratio of solid radioactive waste to units of energy produced 
Brief Definition 
Radioactive waste arisings from nuclear fuel cycles 
or other fuel cycles per unit of energy produced. 
Waste arisings destined for disposal in solid form 
are classified and categorized according to national 
definitions or as proposed here. These quantities 
consider all radioactive wastes from energy fuel 
cycles, including mining, milling, energy 
generation and other related processes. This 
indicator represents a set of indicators that includes 
one for each type of radioactive waste 
Units 
Cubic metres (m
3
) of radioactive waste destined for 
disposal in solid form and tonnes of heavy metal 
(tHM) for spent fuel per terawatt hour (TWh) of 
electricity produced or tonne of oil equivalent (toe) 
or exajoule (EJ) of final energy produced in a 
selected period of time (e.g. several years or 
lifetime of facility)
