Investment Rating - The report maintains a positive investment rating for the chemical industry, highlighting the potential benefits from the "dual carbon" policy implementation [5]. Core Insights - The "dual carbon" policy is expected to significantly impact the chemical industry, with a focus on carbon emissions control becoming a rigid constraint during the 14th Five-Year Plan period [6][14]. - The report identifies that the attention towards "dual carbon" from provincial leaders has increased by 137% since September 2025, indicating a shift in focus towards carbon emissions as a critical performance metric [7][18]. - The chemical industry is anticipated to undergo structural changes, with high carbon intensity sectors facing supply constraints, while low-carbon leaders are expected to benefit from the transition [8][30]. Summary by Sections 1. "14th Five-Year Plan": Carbon Peak Closing Battle - Local carbon assessments may treat carbon emissions as an equally important rigid constraint [15]. - High carbon intensity sectors such as ammonia fertilizer, coal chemical, and chlorine-alkali are likely to face capacity constraints first [29][30]. 2. Petrochemical "Dual Carbon" Opportunities - The petrochemical sector is expected to undergo a transformation driven by the "dual carbon" goals, with a focus on optimizing supply and demand structures [38]. - Refining sector dynamics are shifting towards improved supply-demand balance due to stringent approval processes for new projects and the elimination of high-energy-consuming capacities [38]. 3. Basic Chemical "Dual Carbon" Opportunities - Coal chemical industry is projected to stabilize supply under carbon limits, driving quality improvements in the sector [3.1]. - Carbon fiber and fluorochemical sectors are expected to benefit from process optimization and green transitions [3.2][3.3]. 4. Investment Recommendations - The report suggests focusing on three categories of leading companies: 1. Integrated leaders in the oil chemical sector with scale and efficiency advantages [8]. 2. Coal chemical leaders with advanced processes and low emissions [8]. 3. High-quality firms in fluorochemical and carbon fiber sectors that align with "dual carbon" goals [8].
