• Status of – and reactions to – the EU Carbon Border Adjustment Mechanism (CBAM) including its relevance for North American industry and policy

• Evolving role of verified carbon markets, including status of high integrity meta-standards, transparency, market infrastructure and new coalitions

In addition, the Summit will see a series of “Spotlight Sessions” featuring leaders from government, business, and finance sharing deeper dive views on hot topics like:

• Carbon removals (nature and engineered)

• Enabling interoperability across emerging and disparate markets

• Carbon capture, utilization and storage (CCUS)
