This briefing note provides an overview on how the use of offset credits is regulated in different emission trading systems (ETS) and carbon pricing mechanisms around the world. It takes into consideration systems that are active and under-development, and looks at whether rules allow the use of domestic offsets, i.e. credits generated by non-covered projects in the same jurisdiction, and/or international offsets, i.e. credits generated by projects in other jurisdictions. The intent is to provide a snapshot of the regulations in place and facilitate the comparison of their design.
