标准定位

CWTT（CaiWei Token & Trade）是 ILUME 集团面向全球碳汇与绿色贸易互通推出的技术标准与业务框架。它定义了碳信用资产从项目开发、核证、注册、交易到退役的全生命周期数据格式、接口规范与互操作协议，旨在打通各国碳市场、企业碳账户与贸易平台之间的信息孤岛。

核心目标

互通性：让林业碳汇、海洋蓝碳、可再生能源、CCUS 等多元资产可在 CWTT 兼容平台间自由流转。
可信性：通过 MRV + 区块链存证 + 第三方核证，确保每一吨碳减排真实、可审计、不可篡改。
效率：标准化 API 与元数据格式，降低碳资产开发、交易和结算成本 30% 以上。
兼容：与 VCS、Gold Standard、CCER、CEA 等主流机制保持映射关系，支持多标准并行注册。

V1.02026 ReleaseLed by CaiWei Cloud

Standard Positioning

CWTT (CaiWei Token & Trade) is a technical standard and business framework launched by ILUME Group for global carbon sink and green trade interoperability. It defines data formats, interface specifications, and interoperability protocols for the full lifecycle of carbon credit assets — from project development, verification, registration, trading to retirement.

Core Objectives

Interoperability: Enable diverse assets such as forestry carbon sinks, blue carbon, renewable energy, and CCUS to flow freely across CWTT-compatible platforms.
Trustworthiness: Ensure every tonne of emission reduction is real, auditable, and tamper-proof through MRV, blockchain notarization, and third-party verification.
Efficiency: Reduce carbon asset development, trading, and settlement costs by over 30% through standardized APIs and metadata formats.
Compatibility: Maintain mapping relationships with mainstream mechanisms such as VCS, Gold Standard, CCER, and CEA, supporting multi-standard parallel registration.
