Response to the article “Carbon accounting approaches and reporting gaps in urban emissions: an analysis of the greenhouse gas inventories and climate action plans in Brazilian cities”
摘要
Leão et al. (2022) criticize the lack of transparency and completeness in the carbon inventories of several Brazilian cities using the GPC Standard, suggesting that methodologies aren't being properly followed. However, this critique may miss some key points: (I) the GPC framework has two levels, BASIC and BASIC+, with AFOLU and IPPU emissions required only in the latter; (ii) the GPC allows some flexibility for "Other Scope 3" emissions, like consumption-based calculations and additional indirect emissions. While not mandated, these can be included for a more comprehensive inventory without risking doublecounting; (iii) the criticism of SEEG, a system designed to capture broader national trends, might overlook its purpose: to provide a generalized view rather than detailed local measurements. Overall, while the authors' concerns are valid, some claims may be exaggerated or misaligned with the GPC's flexible approach to carbon inventory. The GPC offers adaptability and could serve as a robust framework if used with a clear understanding of its guidelines and limitations.
