This update provides a summary of key developments across global compliance and voluntary carbon markets, and emerging environmental markets. It draws on select data, commentary and insights available in full in the Carbon Intelligence Package.
Highlights from the June edition

- Australian carbon market: ACCU prices firmed through June, with generic spot ACCUs briefly reaching their highest levels since November 2025, before closing the month broadly rangebound.
- New Zealand carbon market: NZU prices climbed to year-to-date highs, supported by expectations of tightening long-term supply, subdued forestry registrations and continued uncertainty around future unit issuance.
- Singapore market: Singapore signed cooperation agreements with Verra, Gold Standard and the ICVCM, while Tanzania became the latest country to sign an MoU with Singapore on carbon credits collaboration.
- Japan market: Japan’s trade ministry is considering using GX-ETS prices as the reference price for CCS support measures.
Voluntary carbon market:
- Voluntary carbon markets remained relatively subdued through June, with trading activity continuing to concentrate around higher-integrity credits while broader market liquidity remained thin.
