We believe that voluntary carbon offsets are likely necessary to mitigate residual, hard-to-abate emissions. We continue to monitor the progress of the Integrity Council for the Voluntary Carbon Market, an independent governance body that aims to set a global standard for high integrity, and their Core Carbon Principles. In 2024, we aligned our guidelines for company participation in the voluntary carbon market with these principles and continue to strengthen our due diligence efforts regarding developer experience, technical requirements and rigor as well as stakeholder engagements that support local communities. Our commitments also include an investment in Climate Asset Management’s Nature Based Carbon Fund and multiple technology projects including offsets from plugging orphan wells.
