This report tracks and quantitatively assesses the green and low-carbon transition of 30 Chinese provincial-level regions over the decade from 2013 to 2022 using the Subnational Low-Carbon and Green Index for China (Subnational LOGIC), which encompasses 26 indicators across four categories: carbon productivity; carbon emissions (covering energy, power, industry, buildings, transport, and agriculture); environmental conditions and land use; and policy systems and public participation. The analysis employs multiple classification frameworks—economic-geographic regions, economic development stages (Pioneer, Leading, Catching-Up, and Developing Economies), national major regional strategies, and energy development positioning—to identify structural divergences in transition patterns. It finds that scores improved across all provinces, with carbon productivity, energy, and power showing nationwide progress while transport, buildings, and industry remain key frontiers for deep decarbonization. The report also presents in-depth case studies of Guangdong, Jiangxi, Shanxi, and Hainan to examine differentiated transition pathways across economic development stages.

This working paper quantitatively examines the scale and climate impact of food loss and waste (FLW) in China, estimating that 430 million tonnes of food were lost or wasted in 2024—roughly 28% of total production—generating approximately 500 million tonnes of CO₂e in carbon footprint and 185 million tonnes of CO₂e in methane emissions. It analyzes the uneven distribution of FLW across supply chain stages and food types, highlighting that while vegetables account for the largest share of losses, livestock products carry disproportionately high emissions intensity. The paper reviews China's evolving policy landscape, including the Anti-Food Waste Law and cold chain development initiatives, while identifying critical gaps in data infrastructure, sustainable cold chain coverage, and consumer behavior interventions. It explores the dual role of cold chain logistics—reducing post-harvest losses while contributing significant energy-related and refrigerant emissions—and assesses the potential of business innovations, public engagement, and food waste valorization to mitigate FLW. Ultimately, the paper advocates for integrating FLW reduction into climate governance frameworks, proposing four priority pathways: establishing systematic FLW data systems, advancing sustainable cold chain solutions, strengthening circular utilization of food waste, and promoting green consumption patterns to unlock a cost-effective, high-potential climate mitigation opportunity.

This policy brief analyzes the green and low-carbon development content in provincial-level recommendations for China's 15th Five-Year Plan (2026–2030). It systematically reviews 30 provincial documents to identify key "dual-carbon" (carbon peaking and carbon neutrality) priorities, including carbon peaking timelines, carbon emissions dual-control systems, new energy system construction, sectoral transitions (industry, transport, buildings, agriculture), and the deployment of zero-carbon parks, zero-carbon factories, and climate adaptation measures. The analysis is based on a systematic review and comparative analysis of provincial policy texts, categorizing and quantifying the frequency and content of policy keywords to identify regional patterns, alignment with national priorities, and local-level implementation focuses.

As of January 2026, a total of 30 provincial-level administrative regions in China had released the full text of their “15th Five-Year Plan” proposals. iGDP found that while the policy statements regarding the priorities of green transition in each province showed a high degree of alignment with the national “15th Five-Year Plan” proposal, they also featured notable local highlights.

This policy brief examines the development of zero-carbon parks in China, analyzing the transition from fragmented local experimentation to nationally coordinated planning. It reviews the policy landscape and standard-setting landscape, categorizing standards into three types (group standards, local standards, and provincial action plans). It then identifies three differentiated regional development models based on analysis of 80 zero-carbon park pilots across eight provinces: emerging industry-driven (eastern coastal regions), clean energy-driven (southwestern regions), and energy transition-driven (central regions). The analysis also synthesizes the multi-dimensional characteristics of park development—energy, industry, transport, buildings, ecology, resource cycling, carbon management, and carbon sinks—and discusses the implications of the July 2025 national policy that formalized zero-carbon park development at the central government level.

This policy brief analyzes reduction opportunities for "super pollutants" (methane, nitrous oxide, hydrofluorocarbons, black carbon, and ground-level ozone) from China's agri-food system. It focuses on three key areas: nitrogen fertilizer use and nitrous oxide emissions, food loss and waste and associated methane emissions, and rural energy use and black carbon emissions from cooking and agricultural machinery. It synthesizes scientific literature, official statistics, and policy documents to quantify emissions, identify mitigation potential, and catalog the climate, health, economic, and social co-benefits of action. It finds that super pollutant mitigation offers "triple-win" outcomes—climate, health, and socioeconomic—and identifies three emerging opportunities: supportive national and provincial policies, expanding green finance and carbon market mechanisms, and the growing role of new agricultural business entities in driving technology adoption at scale.
