A Pollutant Release and Transfer Register (PRTR) is a publicly accessible database or inventory of chemicals or pollutants released to air, water and soil and transferred off-site for treatment. It brings together information about which chemicals are being released, where, how much and by whom.

OECD has played a key role in developing the concept of a PRTR and supported the development and implementation of a PRTR in member countries.
