AlliedOffsets’ latest report provides a data-driven overview of how the voluntary carbon market evolved in 2025, highlighting where growth has returned, where risks remain, and how buyer behaviour is changing.

Here are some of the key findings from our analysis:

• Retirements and offtakes increased year-on-year, with total market value surpassing $10 billion for the first time since AlliedOffsets began tracking the voluntary carbon market in 2020.

• Market growth was driven by a limited pool of repeat buyers, with participation failing to expand at the same pace as volumes and demand becoming increasingly concentrated.

• Integrity and policy signals strengthened in 2025, with CCP-labelled retirements increasing by more than 95% compared to 2024 and regulatory schemes increasingly accepting or considering the use of offsets.
