In the past few years, the global coal chemical industry has accelerated its restructuring. Europe is accelerating its "stall" under the dual pressure of energy costs and carbon policies, while China is relying on its resource endowment and strategic investment to achieve a "leap". The balance of global coal chemical competition has irreversibly tilted towards the east.1, Europe 'stalls': Upstream contraction, carbon tax pressure increasesFrom 2022 to 2025, the cumulative production capacity of European chemical industry will be shut down by 37 million tons (accounting for 9% of the total production capacity), with a single year shutdown of 17.2 million tons in 2025. Ethylene production capacity has been reduced by about 2 million tons per year compared to 2021, while synthetic ammonia and methanol have also contracted simultaneously.Root cause: After the shutdown of Gazprom, the cost of LNG in Europe was 3-4 times that of Gazprom, and the price of industrial gas in Germany once exceeded 10 times before the war. In 2026, the EU CBAM will be fully implemented, with a carbon price of about 70-80 euros/ton, while China's carbon price is only 60-80 yuan/ton, putting significant carbon cost pressure on coal based product exports.2, China's' leap ': leading in production capacity, exports, and investment comprehensivelyChina is the only country in the world with large-scale industrialization of modern coal chemical industry. By 2025, the global coal chemical market size will exceed 800 billion US dollars, with China accounting for 42%.1. Capacity: Approximately 11 million tons of coal to oil, 10 billion cubic meters of coal to gas, and 16 million tons of coal to olefin, basically achieving the "14th Five Year Plan" target. Methanol coal production accounts for 78%, urea 73%, PVC 79%, Ethylene glycol 40%, olefin 25%.2. Export: By 2025, urea exports will reach 4.894 million tons (+17.8 times year-on-year), with an average price of 410 US dollars per ton. National Energy Group's chemical product exports increased by 74% year-on-year, covering 41 countries.3. Investment: The total investment for major projects in the chemical industry in 2026 is 837.8 billion yuan, with coal to olefin projects under construction exceeding 300 billion yuan. The cumulative investment for the four major bases in Xinjiang, Inner Mongolia, Shaanxi, and Ningxia exceeds 600 billion yuan.Cost advantage: Baofeng Energy's largest coal to olefin project in Inner Mongolia, with an annual output of 3 million tons, has a stable olefin gross profit margin of 30%.3, Global Landscape: From 'Following' to 'Leading'1. China's coke production accounts for over 65% of the world's total, and new coal chemical technologies continue to iterate: coal to aromatics, coal based biodegradable materials, and coal to alpha olefins are accelerating industrialization.2. The "15th Five Year Plan" for the first time explicitly states "strengthening coal to oil and gas production capacity and technological reserves" and incorporates it into the national energy security strategy. In 2027, the chemical industry will be included in the national carbon market, and carbon constraints will accelerate the clearance of outdated production capacity, expanding the advantages of leading enterprises.4, Outlook: From scale expansion to value leap1. High end: Upgrading from basic chemicals to new materials and fine chemicals, biodegradable materials and alpha olefins have become new growth poles.2. Greenization: Green hydrogen coupled with coal chemical industry (such as Baofeng Energy's Inner Mongolia project) and carbon capture and storage technology have become key pathways for carbon reduction. The 2026 government work report sets the first carbon emission intensity target, and fully implements carbon dual control during the 15th Five Year Plan period.3. Globalization: CBAM drives green transformation, and the geopolitical turmoil in the Middle East highlights the value of China's stable supply chain. China is moving from a "chemical powerhouse" to a global chemical "core hub". List of Core HighlightsEurope's' stall ': 37 million tons of production capacity will be shut down from 2022 to 2025, and 17.2 million tons will be shut down in a single year in 2025; CBAM carbon price of 70-80 euros/ton creates cost pressure on coal chemical exportsChina's' leap ': China accounts for 42% of the global coal chemical market, with a coal to olefin production capacity of 16 million tons and a methanol/urea/PVC coal to olefin ratio of over 70%Investment explosion: The total investment in chemical projects in 2026 is 837.8 billion yuan, with coal to olefin exceeding 300 billion yuan, and the four major bases accumulating over 600 billion yuanCost advantage: Baofeng Energy Inner Mongolia project olefin gross profit margin of 30%Export volume increase: By 2025, urea exports will reach 4.894 million tons (+17.8 times), with China National Energy Corporation's exports increasing by 74%, covering 41 countriesPolicy reshaping: Incorporate the "15th Five Year Plan" into the energy security strategy, enter the carbon market in 2027, and "strictly control the total amount and improve quality"

Europe's "deindustrialization": Plant Closures and Frozen InvestmentsOver the past few years, the European chemical industry has undergone an unprecedented deep reshuffling. According to data from the European Chemical Industry Council (CEFIC), between 2022 and 2025, the closure of production capacity in the European chemical sector surged sixfold, with cumulative capacity losses reaching 37 million tons over four years, accounting for approximately 9% of the industry's total capacity. More alarmingly, annual investment volume plummeted from 2.7 million tons in 2022 to 300,000 tons in 2025, with capital expenditures declining by 81% over the same period.The root cause of this shutdown wave is the "out-of-control" surge in Europe's energy costs. Before the Russia-Ukraine war, the EU sourced about 40% of its natural gas and 30% of its crude oil from Russia. As Russian gas pipelines were shut down one after another, Europe was forced to import liquefied natural gas (LNG) from countries like the U.S. and Qatar, with costs 3-4 times higher than Russian gas. The soaring energy prices directly breached the economic threshold of chemical production lines—Germany's industrial natural gas prices once exceeded pre-war levels by more than 10 times, while electricity prices in southern Norway surged 20-fold. Cefic Director General Marco Mensink bluntly stated: "The industry is on the verge of collapse, with shutdowns doubling within a year while annual investments have dropped to nearly zero. Both these trends are accelerating, not slowing."China's Chemical Industry "Expands Against the Trend": Capacity, Exports, and Cost AdvantagesAmid the global chemical industry's overall challenges of declining capacity utilization and corporate profitability pressures, China's market has demonstrated unique growth resilience. According to BloombergNEF data, global net ethylene capacity will reach 14.6 million tons in 2026, approximately twice the average annual new capacity added over the past five years. China accounts for a staggering 56% of this new ethylene capacity, making it the primary driver of this expansion. By the end of 2025, China's ethylene production capacity will surpass 60 million tons, maintaining its position as the world's largest ethylene producer.From a more macro perspective, China's chemical exports account for 38% of the global market share, up 12 percentage points from 2020. China's ethylene production capacity represents 25% of the global total, while its benzene production capacity exceeds 30%, and xylene production capacity accounts for 50% of the global share. Both polyethylene and polypropylene production capacities rank first in the world. In the fields of basic raw materials and synthetic resins, most of China's products have secured the top global position.The Global Landscape of "Rising East, Declining West": Globalization Opportunities for Chinese Chemical IndustryFirst, capitalize on the dividends of global production capacity transfer.Second, the premium logic driven by supply chain security.Third, the upgrading opportunity of high-end transformation.From a longer-term perspective, the strategic value of China's chemical industry is being redefined. The 2026 government work report introduced carbon emission intensity targets for the first time, and the dual carbon emission control system will be fully implemented during the 14th Five-Year Plan period. This means carbon emissions will become a rigid constraint indicator in local government evaluations. The raising of carbon emission thresholds will further accelerate the exit of small and medium-sized enterprises, while supply-side concentration is expected to continue rising. The profitability and industry influence of leading enterprises will further strengthen. Key Highlights at a GlanceEurope's Recession: From 2022 to 2025, the European chemical industry cumulatively shut down 37 million tons of production capacity, accounting for 9% of Europe's total capacity. Annual investments dropped from 2.7 million tons to 300,000 tons, with capital expenditures declining by 81%China's Advance: China's ethylene production capacity exceeds 62.88 million tons (accounting for over 30% of the global share), with chemical exports reaching $331.13 billion, representing 46% of global chemical salesCost advantage: The unit cost of integrated refining and petrochemical units in China is 30% to 40% lower than that in Europe, and the cost advantage of coal-to-olefins further expands under high oil price conditionsGeopolitical Impact: The explosion at the Jubail Industrial Zone affected 6% to 8% of global petrochemical production capacity, while the disruption of the Strait of Hormuz drove Asian naphtha cracking profits to record highsPolicy Reshaping: The EU CBAM is officially implemented, China's dual carbon emission controls fully transition, and supply-side concentration is expected to continue rising
