The regulation of a designated material under extended producer responsibility (EPR) creates new markets and has a direct impact on pre-existing markets. The characteristics and scope of these markets (and their competitive dynamic) are determined by the relationships and interactions between obligated producers, between these producers and their producer responsibility organizations (“PRO” and in BC “stewardship agencies”) and between producers (and their PROs) and existing players such as municipalities and private waste companies. The competitive dynamic of these markets is largely impacted by the obligations set forth for producers by governments under their respective EPR laws. As such, this study addresses the first phase of the BC Ministry of Environment’s efforts to understand the relationship between EPR as a policy measure to hold producers responsible for the end-of-life management of products and packaging and competition as a market property that emerges as producers seek to discharge their responsibilities under EPR laws specific to a given jurisdiction. The objective of this study is to describe the market dynamics of select jurisdictions with EPR laws with a specific focus on gaining an understanding of the interplay of factors shaping the competitive dynamic at one or more levels of producer compliance (e.g., competitive procurement of recycling services by PROs, competition between PROs in the same product categories and market segments, competition between a PRO and producers in the same product category and market segment). Ultimately the findings of this Phase 1 effort will be used in subsequent activities to assess approaches to regulating EPR in British Columbia that lead to greater economic efficiency and environmental effectiveness.
