C100 Research & Notes
Methodology primers, quarterly rebalance notes, and deep-dives on the carbon-credit integrity stack. Curated by the Carbon Index Protocol research desk.
Triangle Digital's Carbon Platform — A Regulated Rails Deep Dive
Deep dive on Triangle Digital's Carbon Platform: the regulated ledger, TCFD/GHG monitoring SaaS, digital-twin lending stack, Minting-as-a-Service, and the Sustainability-linked Asset Registry — assessed for institutional buyers, banks, and project developers.
C100 Methodology v0.1 — Scoring the Carbon Stack
A from-first-principles walkthrough of the C100 scoring model: the eight CIP dimensions, the integrity weighting, the symmetry between supply-side and demand-side firms, and the guardrails against carbon theater.
Greenwash Risk — Detecting Disclosure Drift in 2026
We compare voluntary registry retirements against audited disclosures across the C100 to flag firms whose claimed climate progress outruns their verified retirements. Twelve names are upgraded to High risk.
Q1 2026 C100 Rebalance — What Changed and Why
The Q1 2026 rebalance added six new constituents and removed five. Net effect: a 180bps overweight to direct air capture and a 90bps underweight to upstream oil & gas.
When Sentiment Diverges From Score
Eighteen constituents currently show sentiment-score divergence. Historically, the underlying CIP score wins ~68% of these episodes over the following six months.
Carbon Credit Quality — The Q-Score Framework
Quality (Q) is the single most heavily-weighted dimension in the CIP composite. This deep-dive documents the four pillars — additionality, permanence, leakage, MRV — and the empirical mapping into a 0-100 score.
Reading the Carbon Flows Panel
A short user-guide to the Carbon Flows panel on every company page. We explain produced vs. retired, the net flow signal, and how flows interact with the Financial Strength score.
