📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本のカーボンクレジット市場（J-Credit）や海外クレジット活用の実務において、退役データの質と透明性は重要。本パッケージは、クレジットの完全退役の実態を検証する手法を提供し、日本の企業が海外クレジットを調達する際のデューデリジェンスに示唆を与える。

In the global GX context

This work contributes to global carbon market integrity by examining retirement heterogeneity across registries and project types. It offers a methodological template for analyzing carbon credit retirement data, relevant to voluntary carbon market participants and disclosure frameworks that rely on credit quality.

👥 読者別の含意

🔬研究者:Provides a reproducible analytical pipeline for studying carbon credit retirement patterns, useful for carbon market research.

🏢実務担当者:Offers insights into credit retirement heterogeneity that can inform procurement decisions and due diligence in voluntary carbon markets.

🏛政策担当者:Highlights the need for transparent and standardized retirement data to ensure market integrity.

📄 Abstract（原文）

Licence scope: MIT applies only to original project code; CC BY 4.0 applies only to original project documentation, aggregate analytical outputs, tables, and figures. No licence is asserted over third-party material, which is not included; see LICENSES.md. This replication package supports the article “Full-Retirement Heterogeneity in the Voluntary Carbon Market: Project Types, Registries, and Composition.” It contains original analytical code, canonical non-row-level outputs, final tables and figures, deterministic exporters for the validated robustness synthesis (Table B1) and corrected Y3 table, input integrity hashes, and documentation of provenance and transformations. The analysis uses a fixed CarbonPlan OffsetsDB snapshot dated 1 June 2026. The canonical primary sample contains 27,249 project-by-vintage observations representing 6,025 projects; Y2 full retirement is the primary outcome. The corrected Y3 sample contains 10,439 observations and 3,743 projects, with 300/300 valid project-cluster bootstrap results. CarbonPlan/registry raw data, row-level derived panels, and diagnostics containing individual project or row identifiers are not redistributed because source-registry rights have not been affirmatively cleared. The package preserves the article's identification limits: results are associational, the timing profile does not identify a causal age effect, and registry/project-type nesting constrains interpretation.
