Carbon accounting that starts from the transactions you already record.从企业已有的业务交易开始的碳核算。
MurrCloud is building carbon intelligence directly into its ERP platform. Purchases, production orders, energy bills and shipments become traceable emission records, calculated with versioned factors under GHG Protocol, ISO 14067 and EU CBAM rules.木耳云正在其 ERP 平台中构建碳排放智能计算能力。采购、生产工单、能源账单和发货记录将转化为可追溯的排放记录，并按 GHG Protocol、ISO 14067 及欧盟 CBAM 规则，使用带版本管理的排放因子进行计算。

One carbon data foundation. Several accounting methods.一个碳数据底座，多种核算方法。
We are not building separate carbon tools for each regulation. A shared foundation collects and standardises activity data once; each method module then applies its own boundary, factors and rules.木耳云不为每项法规单独开发碳核算工具。共享底座统一采集和标准化活动数据，各核算模块再分别应用各自的边界、因子和规则。

One set of business records can serve many accounting purposes. Each result states exactly which rules, boundary and factors produced it.一份原始业务数据，可以服务多种核算目的；但每一种核算结果必须明确使用哪套规则、边界和因子。
AI suggests classifications and factor matches. A deterministic engine produces the official numbers, and low-confidence matches go to human review.AI 负责分类建议和因子匹配；正式结果由确定性计算引擎生成，低置信度结果进入人工审核。| General carbon accounting通用碳核算 | EU CBAM欧盟 CBAM | |

Where the carbon data comes from碳数据从哪里来
Each ERP module already records the physical activity behind an emission. The carbon module listens for the business event that confirms it.每个 ERP 模块都已记录产生排放的实际业务活动。碳模块在业务事件确认时自动生成排放活动记录。

The arithmetic behind the platform平台背后的计算逻辑
These simplified calculators show the activity × factor logic the platform runs. Every factor is editable; defaults are illustrative examples, not official values.以下简化计算器展示平台采用的“活动数据 × 排放因子”逻辑。所有因子均可修改，默认值仅为示例，并非官方数值。
The separate calculator workspace follows the June 2013 Chinese coal-fired power plant workbook, with formula traces and clearly labelled historical factors.独立计算工作区依据 2013 年 6 月版中国燃煤电厂工具，提供公式溯源，并明确标注历史排放因子。
Enter valid, finite numbers within the stated limits. CBAM production must be greater than zero. Values are unavailable when inputs or arithmetic are invalid.请输入符合限制的有效有限数值。CBAM 核算期产量必须大于零；输入或运算无效时不显示结果。
GHG Protocol Scope 2 asks for both location-based and market-based totals. A full market-based result uses supplier-specific or residual-mix factors.GHG Protocol Scope 2 要求同时报告位置法和市场法结果；完整的市场法需使用供应商特定因子或剩余组合因子。
