For this reason, both Canada and the United States “lock” their data sets on a specific date and use this “locked” set for annual summary reports. Both coun- tries then correct errors and issue revised data sets for all reporting years in subsequent years. Paper: Fifty percent recycled, with 20 percent post-consumer The CEC follows a similar process. For the purposes of this report, the NPRI (with one exception noted below) content / no coatings, no elemental chlorine and TRI data sets as of June 1996 were used. The CEC is aware that changes have occurred to both data sets for Ink: Vegetable ink containing no chlorine or heavy metals the reporting year 1994 since this time that are not reflected in this report. These changes will be reflected in the next report, which will summarize the 1995 data and make year-to-year comparisons with the revised 1994 data. Fountain Solution: No isopropyl alcohol / less than one percent VOCs Press Washes: Low VOC press washes used One exception in this year’s report is an error in the NPRI data that was related to CEC by Environment Canada in time for inclusion in this report, but that is not reflected in the NPRI Summary Report for the 1994 data. This Design & Layout: Desjardins Bibeau is an error in one facility’s report which caused the over-reporting of air emissions by over 10 million kilograms.

In 1995, the CEC’s Council of Ministers decided to create a North American Pollutant Release Inventory to help the public better understand pollutant releases in North America as a whole. This report is the first in a series of annu- al reports on pollutant releases in North America based on information brought together from existing pub- licly available information in the three countries. This report analyzes 1994 data from pollutant release and transfer registers in Canada and the United States, profiles the pilot pollutant release and transfer register (PRTR) project in Mexico and presents a chapter on environmental information in annual corporate reports. It follows the publication Putting the Pieces Together: The Status of Pollutant Release and Transfer Registers in North America, a background document published in 1996. The CEC Secretariat would like to thank all who worked on this initiative, especially the excellent team of consultants who prepared this report: Hampshire Research Associates, Inc. (Alexandria, Virginia), Environmental Economics International (Toronto, Ontario) and Corporación Radian, S.A. de C.V. (Mexico City). An effort such as this could only happen through the combined cooperative efforts of the national PRTR programs. The CEC Secretariat would like to express appreciation for the continuing support from Environment Canada (François Lavallée and Marielle Nobert), Instituto Nacional de Ecología (Adrián Fernández B. and Luis Sánchez C.) and the US Environmental Protection Agency (Susan Hazen and John Harman). An essential part of the report’s development included the consultative review of draft documents and a public meeting. Numerous representatives from industry, academia and nongovernmental organizations generously donated time and energy to participate in the consultative process, and the CEC Secretariat gratefully thanks them all. Finally, this report would not have been possible were it not for the leadership and hard work of CEC Program Manager for Technical Cooperation Lisa Nichols and CEC Director Janine Ferretti.
