Cooperation and Development (OECD)
• PRTR Task Force developing
recommendations for PRTR comparability;
• Intended mainly for emerging and future PRTR
systems;
 To make their data more comparable with:
- one another, and
- with older PRTR systems.

3. The Approach
• Develop a list of chemicals to be covered;
• Develop a list of sectors to be covered;
• Develop reporting elements, e.g.;
• Reporting thresholds;
• Quantities to be reported
• onsite releases, offsite releases;
• transfers
• Pollution prevention-specific information

4. The Approach
Used Five PRTR Systems and Kiev Protocol on PRTRs as
a Starting Point:
• Australia’s National Pollutant Inventory (NPI);
• Canada’s National Pollutant Release Inventory (NPRI);
• European Pollutant Release and Transfer Register (E-PRTR);
• Japan’s Pollutant Release and Transfer Register (JPRTR)
•United States’ Toxics Release Inventory (TRI);
• Kiev Protocol on PRTRs

5. Progress to Date
• Developed Long Chemical List;
• Developed Short Chemical List
• Developing Long Reporting Sector List
• Developing Short Reporting Sector List

6. Next Steps
• Complete Long Reporting Sector List;
• Complete Short Reporting Sector List;
• Integrate chemical and sector work;
• Begin to develop guidance on
global comparability of PRTRs.
