日本語
タイ・ピッサヌローク県の自治体を対象に、質問票データから都市固形廃棄物管理のGHG排出量を終末処理と輸送段階で算出した研究。市自治体が年平均26,531トンCO2-eqと最大で、町・準区・行政組織と続く。人口当たり排出は比例せず、人口密度や廃棄物発生・管理慣行の差を反映する。自治体類型に応じた差別化された廃棄物部門の緩和策の必要性を示す。
English
This study estimates GHG emissions from municipal solid waste management in Phitsanulok Province, Thailand, using questionnaire data across municipality types, covering end-of-life treatment and transport. City municipalities emit the most (26,531 t CO2-eq/yr), followed by towns, subdistricts, and administrative organizations. Per-capita emissions do not scale proportionally, reflecting differences in density, waste generation, and practices. Findings call for differentiated waste-sector mitigation strategies in Thailand and other developing countries.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では直接の開示制度連動は薄いが、自治体規模別の廃棄物排出原単位は地域脱炭素計画やScope 3廃棄物カテゴリ推計の参考になりうる。
In the global GX context
Adds subnational, municipality-typology evidence on waste-sector emissions, relevant to GHG inventories and waste-related Scope 3 accounting under ISSB/CSRD disclosure where waste treatment data are often sparse.
👥 読者別の含意

🏢実務担当者:廃棄物処理に伴う排出原単位の地域差を、Scope 3カテゴリ5推計や地域調達判断の参考にできる。
🏛政策担当者:自治体規模に応じた差別化された廃棄物部門の緩和策設計の根拠となる。
📄 Abstract（原文）
Thailand is among the countries most vulnerable to climate change, ranked 8th by the Global Climate Risk Index (CRI) for the period 1999–2018. In response, the National Strategy 2018–2037 outlines pathways for both adaptation and mitigation. The waste management sector is a notable contributor to greenhouse gas (GHG) emissions, accounting for more than 16,000 Gg CO2-eq, approximately 4–5% of Thailand’s total emissions. Municipal solid waste (MSW) management is particularly relevant in developing countries, where emissions vary considerably across municipality types. This study aims to determine GHG emissions from MSW management in Phitsanulok Province, Thailand, using questionnaire-based data collected from municipalities. Emissions were calculated for both end-of-life treatment and transportation stages. The results reveal significant differences across municipality types. City municipality generated the highest average emissions (26,531 tonnes CO2-eq/year), followed by town municipality (4206 tonnes CO2-eq/year), subdistrict municipality (1837 tonnes CO2-eq/year), and subdistrict administrative organization (1168 tonnes CO2-eq/year). While total emissions were greatest in the city municipality, per capita emissions did not scale proportionally, reflecting differences in population density, waste generation, and management practices. This province-scale analysis provides new insights into the role of municipality type in shaping waste-related emissions. The findings underscore the importance of differentiated climate mitigation strategies in the waste sector to develop more sustainable, low-carbon MSW management systems in Thailand and other developing countries.
