The report examines how G20 nations, which generate approximately two-thirds of global plastic waste, can utilize extended producer responsibility (EPR) to combat marine plastic pollution. Through a scoping review of 100 sources, it identifies a disparity in effectiveness between mandatory and voluntary EPR schemes, noting that mandatory systems generally achieve higher recycling collection rates. The document provides a detailed mapping of EPR regulations across G20 members and proposes a multi-level approach combining legislative strengthening, market incentives for recycled plastics, technological innovation in ecodesign, and the formal integration of informal waste workers to prevent plastic leakage into the oceans.

The report compares forest and land use policies in Argentina, Brazil, Canada, China, France, Germany, and the United States. It finds that Brazil's Forest Code (Law No. 12.651/2012) maintains more stringent requirements for private landowners than the other reviewed nations, particularly regarding mandatory riparian buffer zones and the requirement to set aside land for biodiversity protection without compensation. While other countries utilize voluntary incentives, easements, or specific species-at-risk policies, Brazil's framework imposes broad, mandatory obligations across all rural properties.

The 2012 Forest Code governs private land use in Brazil through Permanent Preservation Areas (APP) and Legal Forest Reserves, utilizing the Rural Environmental Registry (CAR) for monitoring. It includes a special regime for landowners who illegally deforested prior to July 2008, offering leniency and offsetting options via the Environmental Regularization Program (PRA). Implementation faces hurdles including state-level legislative delays, legal challenges regarding constitutionality, and a lack of capacity among landholders.

The document argues that Indonesia's economic growth is threatened by environmental degradation, specifically deforestation and peatland fires. While water security is prioritised across sectors, the energy and agriculture sectors focus on built infrastructure rather than forest conservation. The report highlights that ambitious food and bioenergy targets risk further deforestation unless productivity is increased or degraded land is prioritised. Governance is complicated by a complex legal framework and a disconnect between national plans and local government implementation. A case study in Aceh demonstrates that increasing oil palm yields to national averages could meet production targets without further land conversion, whereas 'business-as-usual' scenarios would require converting 220,000 hectares of land.
