UNITAR, in a joint effort with UNECE, UN Environment and OECD, organized the 3rd Global Round Table on Pollutant Release and Transfer Register (PRTRs) which took place last week at the Palais De Nations, Geneva. Jorge Ocana, manager of the Chemicals and Waste Management Unit, was invited to moderate the discussion among different stakeholders on experiences and opportunities of PRTRs, and how such systems could contribute to sustainable development.
