August Pricing Analysis - Global Voluntary Carbon Markets

Global voluntary carbon prices softened broadly in August as Nature Based broad stepped down 5.5% MoM to $18.01/MT in a single 4-Aug session with no drift before or after, while the removal complex diverged sharply as Nature Based Removal fell 4.7% against a completely flat Tech Removal basket, a split consistent with Microsoft's disclosed 80%-plus cut to carbon removal investment in H1 2026.

SUMMARY

Global VCM softened broadly in August, led by Nature Based broad's single-session step from $19.05/MT to $17.95/MT on 4-Aug (-5.5% MoM), with activity muted for the rest of the month. Quality differentiation compressed within the BeZero rating tiers as AA fell faster than A, narrowing the AA-to-A spread from $2.22/MT to $1.90/MT. The removal complex diverged sharply: Nature Based Removal fell 4.7% with real intra-month variation while the broader Tech Removal basket held completely flat, a split consistent with Microsoft's disclosed 80%-plus cut to carbon removal investment in H1 2026, though no transaction-level data confirms the link. Regionally, Turkish Wind collapsed 60.6% between May and July while Indian Wind rose 30% over the same window, both converging to an identical $0.65/MT by July and holding flat since.

  • Monthly avg $18.01/MT vs July's $19.05/MT (-5.5% MoM); July itself was completely flat at $19.05/MT for all 23 trading days
  • The entire MoM move traces to the single 4-Aug session; no drift before or after

CROSS-MARKET DYNAMICS

  • Quality premium compressing as AA-rated fell faster than A-rated; Nature Based Removal softened while the broader Tech Removal basket stayed dead flat

  • BeZero AA-to-A quality spread narrowed from $2.22/MT (Jul) to $1.90/MT (Aug), a 14.4% compression, as AA fell faster (-6.9%) than A (-3.1%)
  • Tech Removal, the broader removal basket, showed zero variance in both July and August ($22.45/MT flat); Nature Based Removal specifically fell 4.7% with real August variation (CV 1.17%), a divergence within the removal complex
  • Microsoft disclosed cutting carbon removal (CDR) investment more than 80% year-over-year in H1 2026 while reporting higher emissions
  • CCP Current trades at a persistent ~$12/MT discount to Nature Based broad and is the most consistently active segment in the set, with CV declining for three straight months (4.38% Jun, 3.99% Jul, 2.56% Aug) while five of the other six segments show near-zero variance in most months

SOMETHING TO WATCH

  • Nature Based Removal diverges from generic Tech Removal:
    • Observation: Nature Based Removal fell 4.7% MoM with real intra-month variation, while Tech Removal was completely flat with zero variance
    • Why it matters: Microsoft's disclosed 80%+ YoY cut to CDR investment is a plausible demand-side driver for nature-based removal specifically, given Microsoft's scale as a removal buyer, though unconfirmed at transaction level
    • What to monitor: whether Tech Removal starts showing variance too, or the two removal segments continue to diverge
  • CCP Current remains the most persistently active segment, but volatility is fading:
    • Observation: CV has declined for three straight months (4.38% → 3.99% → 2.56%)
    • Why it matters: CCP-labeled credits are the clearest read on quality-differentiated demand; continued fade toward the dormancy seen elsewhere would remove the one segment still showing real price discovery
    • What to monitor: whether CCP Current CV keeps compressing toward zero in September or stabilizes
  • Nature Based Avoidance activated in August after two flat months:
    • Observation: CV was 0% in June and July, then rose to 1.74% in August
    • Why it matters: opposite pattern from most other segments in this set; worth confirming this is genuine price discovery rather than an assessment artifact, given several adjacent VCM series have shown irregularities this cycle
    • What to monitor: whether the variance persists into September or reverts to flat
