COMMI SSION IMPLEMENTING DECISION (EU) 2021/19 
of 18 December 2020 
laying down a common methodology and a format for repor ting on reuse in accordance with 
Directiv e 2008/98/EC of the European Parliament and of the Council 
(notif ied under document C(2020) 8976) 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION, 
Havi ng regar d to the Treaty on the Functioning of the European Union, 
Havi ng regard to Directive 2008/98/EC of the European Parliament and of the Council of 19 Novem ber 2008 on wast e and 
repealing certain Directives (1), and in particular Articles 9(7) and 37(7) thereof, 
Whereas: 
(1) Directive 2008/98/EC lays down an obligation for Member States to take measures to encourag e reuse as part of 
their waste prevention programmes, and to monit or and assess the implementation of their measures on reuse by 
measur ing reuse in accordance with a common methodology , which is to be established by the Commission. 
(2) Directive 2008/98/EC also lays down an oblig ation for Member States to repor t data on reuse to the Commission 
ever y year in a format to be established by the Commission. 
(3) The common methodology and the format for repor ting are closely linked and are to be applied together . In the 
inter est of simplicity and ease of application, it is theref ore appropr iate to adop t both measures in a sing le act. 
(4) In order for the measur ing and repor ting to be as accurate as possible, double counting of products should be 
avoided. Only the products that are actually being reused should be count ed. Products that are merely offered for 
reuse, such as products that are donated to reuse operat ors and other products for which reuse is not certain, 
should not be included in reuse measured and repor ted to the Commission. 
(5) In view of the limitations to and difficulties in collecting data on reuse due to the broad scope of product catego ries, 
the fact that measurement of reuse is a novel exercise and the administrative burdens associate d with the collection 
of data on reuse, the common methodology for measur ing and the format for repor ting should be propor tional, 
appropr iate and cost efficient. Theref ore, the common methodology should allow for the use of a variety of data 
gathering tools to measure reuse. 
(1)OJ L 312, 22.11.2008, p. 3. EN Offi cial Jour nal of the European Union 12.1.2021                                                                                                                                            L 10/1   
(6) The common methodology should focus as much as possible on the collection of quantitative data on reuse in order 
to allow for the deter mination of the scale of the reuse sector . Such quantitative data should be collected on a regular 
basis. In order to limit the administrative burden on Member State author ities while ensur ing that the data measured 
and repor ted are suffi ciently up to date, Member States should measure the reuse for a given product catego ry at least 
once ever y third year. 
(7) In order to monitor the implementation of measures on reuse and to gain a better understanding of the impacts of 
the measures taken by Member States to stimulate reuse, the common methodology for repor ting on reuse should 
also allow for an identification of key measures to facilitat e reuse. 
(8) In order to monit or reuse and to gain a better understanding of the reuse sector , repor ting on reuse should include a 
combination of qualitative and quantitative data. Certain data should be repor ted on a volun tary basis, including the 
data on reuse for specifi c channels through whic h a product chang es ownership, to facilitate the exchang e of best 
practices and allow the stak eholders involved to gain a better understanding of reuse. 
(9) The measures provi ded for in this Decision are in accordance with the opinion of the Committee established by 
Article 39 of Directive 2008/98/EC, 
HAS ADOPTED THIS DECISION: 
Article 1 
Common methodology for the measurement of reuse 
1. For the purposes of Article 9(4) of Directive 2008/98/EC, Member States shall measure reuse by carrying out a 
qualitative and a quantitative monitoring of measures on reuse. 
2. The qualitative monitori ng refer red to in paragraph 1 shall include an identif ication and descr iption of measures on 
reuse and an assessment of their impacts or expected impacts, on the basis of the available data. The qualitative 
monitori ng shall be carried out each year. 
3. The quantitative monitori ng refer red to in paragraph 1 shall be carried out by measur ing reuse generat ed by reuse 
operat ors or households in accordance with any of the followi ng methods or a combination of those methods or any 
other method equivalent in term s of relevance, representativeness and reliability: 
(a) direct measurement of reuse by using a measur ing device to determine the mass of reused products; 
(b) mass balance calculation of reuse on the basis of the mass of inputs and outputs of products in reuse operations; 
(c) questionnaires and inter views of reuse operat ors or households; 
(d) diar ies of individuals keeping a record or log of information on reuse on a regular basis. 
The quantitative monitoring for a given product catego ry shall be carried out at least once ever y three years. The first 
monitori ng shall cover all product catego ries and shall be carried out for the first repor ting period refer red to in the third 
subparagraph of Article 37(3) of Directive 2008/98/EC. 
4. Member State s shall take appropr iate measures to ensure the reliability and accuracy of the data on reuse. In 
particular , Member States shall ensure that the measurement of reuse carried out in accordance with the common 
methodology set out in this Article is based on a representative sample of the population or of reuse operators or 
households as applicable. EN Offi cial Jour nal of the European Union L 10/2                                                                                                                                            12.1.2021   
Article 2 
Repor ting on reuse 
Member States shall repor t the data and submit the quality check repor t concer ning the implementation of Article 9(4) of 
Directive 2008/98/EC in the format laid down in the Annex.
