Global Chemical Industry Faces Deepening Decarbonisation Dilemma Amid Economic Pressures

The global chemical industry is confronting a severe decarbonisation challenge, as economic headwinds and trade instability force cuts in capital expenditure, while ambitious climate targets demand massive investment for technological upgrades and facility retrofits. A stark contrast exists between the urgent need for funding and varying regional market willingness to pay for green transitions.

1. Decarbonisation Investment Faces a Cash Flow Winter

Progress on reducing emissions in the chemical sector is significantly behind schedule. According to World Economic Forum data, the industry's absolute emissions increased by 6% between 2019 and 2023, with emissions intensity remaining at 1.3 million tonnes of carbon dioxide equivalent. The International Energy Agency (IEA) calculates that this emissions intensity must be reduced to 920,000 tonnes of carbon dioxide equivalent by 2030. Furthermore, assuming a 70% expansion in industry scale by 2050, annual emissions must be cut by 85%. A PwC estimate suggests investments ranging from US$1.5 trillion to US$3.3 trillion will be required by 2050 to meet these goals.

Current corporate investment appears insufficient. Over 190 member companies of the American Chemistry Council (ACC) have collectively invested US$12.7 billion in sustainable processes, achieving a 14% reduction in emissions intensity since 2017. Major firms like BASF have identified key technological pathways, including bio-based feedstocks and carbon capture. However, given the prolonged industry downturn, the sustainability of this investment level is uncertain.

The global chemical industry is enduring a sustained market slump. Capacity adjustments in European cracking units and heightened trade uncertainty, partly due to the Trump administration's tariff policies, have prompted industry leaders like BASF and Dow Chemical to implement cost controls and tighten capital spending. ACC data indicates that high interest rates, tariff barriers, and geopolitical risks have led to a sustained slowdown in US chemical capital expenditure growth. Projections show a 3.9% increase to US$39 billion in 2024, followed by a 1.6% decline in 2025, with only a modest recovery of 2.5% anticipated in 2026.

Despite annual pledges exceeding $1 billion for sustainability from companies like BASF and Dow, economic weakness continues to constrain decarbonisation spending. ACC Vice President of Sustainability Mitchell Toomey noted that geopolitical complexities and evolving consumer demands are fostering more cautious investment decisions. He emphasised, however, that capacity expansion and emissions reduction are not mutually exclusive, citing that new facilities are far more efficient and current technology allows for "efficiency-enhancing emissions reduction projects" that can also lower operational costs.

2. Dual Constraints: Funding Shortfalls and Technological Lag

A combination of budget cuts for sustainability, withdrawn policy incentives, and insufficient technological maturity has caused widespread stagnation in net-zero projects. A prominent example is Dow Chemical's suspension of its US$6.5 billion ‘Zero Carbon Pathway’ cracker project in Alberta, Canada. Originally scheduled for commissioning in 2027, the facility was planned to produce 3.2 million tonnes of net-zero polyethylene annually, aiming to be the world's first net-zero ethylene complex. Impacted by industry downturns, rising construction costs, and tariff uncertainties, the project entered indefinite suspension in April 2025.

Policy gaps exacerbate these challenges. In summer 2025, the US Department of Energy withdrew US$3.7 billion in emissions reduction funding, affecting key projects including ExxonMobil's hydrogen burner and Eastman Chemical's molecular recycling initiative. Technologically, BASF has acknowledged that core decarbonisation technologies like electrically heated cracking furnaces are not expected to achieve large-scale deployment until after 2030. A pioneering demonstration plant for such furnaces, developed jointly with Saudi Basic Industries Corporation and Linde Group, only commenced operations in Ludwigshafen, Germany, in April 2025.

3. Value Chain Emissions Reduction Faces 'Accounting Blind Spots'

The lack of policy stability and the challenges in managing Scope 3 emissions, which account for supply chain emissions, have become significant institutional barriers. André Arnaud, Dow's Chief Sustainability Officer, stated that "a stable and predictable policy environment is a prerequisite for industry action." However, multiple policy contradictions exist. The US SEC's 2024 climate disclosure rules excluded Scope 3 emissions, which represent 75% of the industry's total emissions. In September 2025, the US EPA further proposed suspending greenhouse gas reporting obligations for large facilities and energy suppliers, prompting warnings from the carbon capture sector that this could strand US$77.5 billion in investments.

The quantification of Scope 3 emissions remains particularly acute: 50.3% originate from upstream supply chains and 25.8% from downstream consumption. Complex value chains, data distortions, and absent accounting standards render effective governance difficult. Corteva's experience demonstrates the scale of the challenge; even if 1,000 core suppliers reduced emissions by 20%, it would only decrease the company's own Scope 3 emissions by 1%.

4. Green Premium Fails to Gain Market Acceptance

Insufficient market demand has emerged as a final hurdle for decarbonisation. BASF acknowledges that a lack of demand for green products undermines the commercial rationale for transition. Dow CEO Jim Fitterling also notes that while customers recognise low-carbon products, their acceptance of a ‘green premium’ remains limited. Against a backdrop of global economic downturn, consumers are prioritising cost control, further constraining the market expansion for sustainable products.

Despite mainstream firms expressing optimism about 2030 targets, data reveals a stark reality: since 2020, direct and indirect emissions from the world's top 12 chemical companies by market capitalisation have fallen by merely 8.7%, with supply chain emissions declining by just 2.1%. Resolving the decarbonisation dilemma requires a synergistic framework where policy-driven stable incentive mechanisms, accelerated adoption of mature technologies, and market cultivation of green demand collectively drive progress.
