Commentary: Big Oil is banking on plastics boom to make up for climate-related losses

The plastics we use every day are produced on such a large incomprehensible scale, we live in an era best labelled the “plasticene”, says two researchers.

LUND, Sweden: Visiting a modern petrochemical plant makes you feel incredibly small.

Enormous compressors roar incessantly, distillation columns tower high, large pipelines full of oil and gas criss-cross the site.

Heat radiates from inspection hatches in furnaces in which hydrocarbons are heated to 850 degrees Celsius to make the molecules crack. It’s easy to get lost in alleys of ducts and pipes, which to an untrained eye, all look the same.

Large tankers moor at the quay to unload cargoes of oil and gas and trucks leave at the other end, filled with plastic pellets.

Tall chimneys release large plumes of flue gases from burning gas and unwanted by-products, using the energy to run processes at the plant.

At night, a flare watches like a bright eye. This is where gases are combusted in case of an emergency or unexpected shutdown of parts of the plant. It’s always burning with a small flame.

The plastics we use every day are produced at such facilities on an almost incomprehensible scale. A scale so large some suggest we now live in an era best labelled the “plasticene”.

And as the climate crisis worsens, plastics production at plants like these is ballooning. Modern lifestyles and practices are intimately entwined with the use of plastics.

Our phones, computers, food packaging, clothes and even renewable energy technologies, such as wind turbine blades and cables connecting them to the power grid, are all, to a large extent, made from plastics.

This means plastic demand is likely to grow for decades to come – not least in developing countries, which will account for the bulk of future demand growth.

In 1950, global production of plastic was estimated to be a mere 2 million tonnes (Mt). In 2015 this had grown to 380 Mt, and along a business-as-usual trajectory it will reach 1,606 Mt by 2050.

Unless mitigated, this growth will also incur a substantial increase in global greenhouse gas emissions – from 1.7 billion tonnes (Gt) of CO2-equivalent in 2015, to 6.5 Gt by 2050.

It has been forecast plastics and petrochemicals, such as fertilisers and solvents (plastics make up close to 45 per cent of sector output) will become the largest driver, accounting for almost 50 per cent of growth in oil demand by 2050, according to estimates by the International Energy Agency (IEA).

Why? Because the raw materials behind plastics and other petrochemicals are fossil fuels.

As traditional demands for oil – vehicle fuels – decline as the transport sector increasingly electrifies, the oil industry sees plastics as a key output that can make up for losses in other markets. Investing in plastics has therefore become a key strategy for fossil fuel firms.

We have long argued climate impacts of plastics and petrochemicals production are neglected, as the debate so far mainly focuses on later stages of plastic life cycles.

More recently, we investigated major plastics producers and their investments likely to increase the production of fossil-based virgin plastics around the world.

The 12 largest petrochemical companies cumulatively announced 88 new projects for production capacity increase and infrastructure expansion between 2012 and 2019.

This is indicative of a global trend of increasing investments in the chemical industry, with available data for key regions showing total investments more than doubled from 2007 to 2019, reaching levels we estimate have not been seen before.

These new expanded facilities will operate for decades once they are opened, adding to current greenhouse gas emissions of the chemical industry – already the third largest of all industries.


On the small island of Yushan in Zhejiang, China, one such new mega-plant is currently being built. The mountain peaks have been flattened and the island expanded into the sea by so much you can no longer recognise its shape.

All this to make way for a gigantic industrial site: Zhejiang Petrochemical Company’s somewhat perversely named Green Petrochemical Base.

How do electricity companies balance cost with carbon emissions reductions commitments? Listen to CNA's The Climate Conversations:

The new site is a fully integrated petroleum refinery and petrochemical production facility. Previously, these processes have typically been in separate facilities and sometimes on different continents.

It will have the capacity to process 800,000 barrels of crude oil per day - enough to fill 50 Olympic-size swimming pools - making it one of the largest refineries in the world.

Most of its chemical products will be common plastics, such as polyethylene for flexible packaging and key petrochemical building block molecules for the production of polyester fibres for textiles.

The Zhejiang project is indicative of a trend as oil and gas companies increasingly look to plastics and other petrochemicals as progressively important markets.

“The future of oil is in chemicals, not fuels,” as a headline in a trade press journal describes it. Our investigations indicate this future is fast approaching.

Information about the industry and its growth is scarce in international statistical databases, such as those hosted by the United Nations Industrial Development Organization, and only extremely aggregated data is available from trade organisations.

We spent the last year collecting data about recent projects from trade press as well as information released by the firms, cross-referencing to identify unique projects.

Two key trends emerged in our analysis: The move towards primarily using oil for plastics and chemicals rather than petrol, and the explosive growth in demand for United States ethane, a byproduct from shale gas produced through fracking.

The first trend is most manifest in China and the Asia-Pacific, where industry experts estimate 70 to 80 per cent of new refining capacity in the next five years will be plastics-focused.

The large oil firms are therefore strategically partnering with regional chemicals and plastics producers – in the Zhejiang case described above, Saudi Aramco has signed an agreement to buy shares in the firm and become a main supplier of crude oil.

The almost insatiable demand for plastics in the Chinese manufacturing industry – producing plastic car parts, cell phones, and textiles for use both domestically and abroad – has also spurred Western chemical firms to make record investments.

The world’s largest chemicals company BASF is investing US$10 billion in a new site in China – the largest investment ever for the company.

The second trend has mainly materialised along the coast of the Gulf of Mexico. The expansion of fracking in the US has created a plentiful supply of ethane, a by-product of fracking for oil and natural gas. While ethane cannot be used as natural gas in most applications, it is an excellent feedstock for the production of common plastics – and is very cheap.

As US ethane production has soared following the shale gas boom, so have the investments in ethane-based plastics production facilities as well as other chemicals produced from shale gas.

With new technology being developed for exporting ethane overseas, this trend quickly diffused to Europe. Adding new export terminals in the US has also recently allowed the export to reach both India and China.


To understand the modern plastics and petrochemical industries of today, we must look to the past.

The modern chemical industry has a long tradition of close connections to the fossil fuel industry. It goes back to the mid-19th century when the first synthetic dyestuffs and other early industrial chemicals were produced from coal tars.

The industry emerged and developed in regions with coal resources and rapid industrialisation, such as the United Kingdom. But it was in Germany key developments were made and led to the foundation of successful companies such as Bayer (in 1863) and BASF (in 1865) – companies still among the top firms in the industry.

Coal remained the main source of raw materials and energy for chemicals for a century and also for the first synthetic plastics, such as Bakelite.

In the mid-20th century, it was clear change was coming, but in the years following World War II the direction remained uncertain.

But in the 1950s, the industry went a different way, as breakthroughs US firms made in petroleum processing during the war quickly spread around the globe with the help of re-industrialisation aid schemes such as the Marshall plan.

This led to the era of petrochemicals, with the industry recording double-digit growth during the 1960s and 1970s. Since then, the industry has expanded into using natural gas, leading to the recent turn towards using gas condensates, such as ethane from fracking.

For more than 150 years, the chemical and fossil fuel industries have fostered a particularly special relationship.

Plastics and other chemicals are today almost exclusively produced from oil and gas. The largest companies producing plastics are often subsidiaries of international oil and gas companies, such as Shell and ExxonMobil, or of national oil companies, such as Sinopec or SABIC.

Other firms started by producing plastics and chemicals before acquiring oil and gas infrastructure, such as INEOS and Reliance.

The firms in the industry rely on licensing technologies developed by global technology suppliers, such as Honeywell, that see chemicals production as a cornerstone for developing the “refinery of the future” – further cementing the connection to fossil fuels.

Although several bio-based plastics have been developed, they still make up less than 1 per cent of the market, which is still completely dominated by fossil-based plastics.


Plastics therefore suffer from a severe case of “carbon lock-in” – a dependence on fossil fuel resources continually reinforced through technology, infrastructure, institutions and behaviour.

The UN Intergovernmental Panel on Climate Change recently warned irreversible effects of intensifying climate change are imminent and agreed targets of limiting global warming to 1.5 or 2 degrees Celsius are soon beyond reach.

At this point in time, all sectors of the global economy ought to be on track to reduce use of fossil fuel resources, especially the most energy and emissions-intensive industries, including cement, steel and chemicals.

From energy efficiency improvements and switching to renewable energy to improving circularity and recycling, there are plenty of opportunities for the industry to invest in solutions for a cleaner environment, as identified by the IEA.

Yet only very few of the plastics and chemical firms have set emission reductions targets aligned with the Paris agreement.

Many countries also continue to subsidise fossil fuels, which filters into plastics and petrochemicals production through reduced costs for fossil building blocks and energy. Addressing these discrepancies between climate targets and real-world actions in the emissions-intensive industries must therefore be a central aim of the COP26 negotiations.

There is increasing awareness of the dangers of plastic pollution. Countries, civil society and businesses are all calling for a global treaty to end marine plastic pollution. And many would like to see a more circular economy for plastics.

It’s particularly worrying, then, petrochemical firms are seemingly so sure their enormous new investments will pay off. It indicates they see no sign of a slowdown in the production of plastics.

Over the past two decades, there has been growing pressure to regulate plastics around the world. Plastic objects and marine plastic pollution have helped elevate plastics to the top of the political agenda in many regions.

The fact we can find plastic literally everywhere and gloomy prospects, such as the prediction there’ll be more plastic than fish (by weight) in the ocean by 2050, make it clear policy responses are needed urgently.

We have identified an increasing number of public policies on plastics. But most are aimed at preventing specific objects, such as plastic bags, plastic bottles, microbeads, and single use plastic, from ending up in natural environments – not addressing the fundamentals of plastics value chains.

Addressing plastic waste and particular objects is necessary, but it is not enough. The plastic pollution prevention policies now in place will not break the wave of plastic waste, let alone alter the fundamental structure of the sector.

Our research shows what drastic changes to the ways we use plastics are required to reach a meaningful form of circular economy.

Resistance against the industry is growing. Around the world, there are loud, local protests against expanding production of plastics and other petrochemicals.

In the US, protesters have successfully litigated against petrochemical production facilities. In Texas, plastic pellets gathered over several years were used as evidence in a lawsuit filed against Formosa Plastics.

In 2019, the company agreed to pay US$50 million to settle the claim it illegally dumped billions of plastic pellets and other pollutants. In addition, it agreed to comply with “zero discharge” of all plastics in the future and to clean up existing pollution.

The outcome encouraged another lawsuit against Formosa Plastics in Louisiana, where protesters have fought the building of new petrochemical facilities.

The planned facility could roughly double toxic emissions in its local area and, according to environmentalists, release up to 13 million tonnes of greenhouse gases a year - the equivalent of three coal-fired power plants, making it one of the largest pollution-causing plastics facilities in the world.

The lawsuit has for now halted the building of the new facilities. But this plant would be located in a heavily industrialised region between New Orleans and Baton Rouge, recognised by the UN as “Cancer Alley” due to the toxic chemical emissions that have affected it for decades.

In the Netherlands, the Plastic Soup Foundation took legal steps to try and stop plastic pellet pollution from the chemical clusters in Rotterdam and Antwerp.

In Taiwan, where petrochemicals have been a key contributor to economic development, several protests against petrochemical sites have made it nearly impossible to expand.

Even in China, which has seen the most rapid expansion of the industry in recent years, protests have been organised in many cities where plans for paraxylene production have been revealed.

These protests have primarily focused on local environmental pollutants and negative effects on neighbouring communities, which tend to be impoverished and minority communities, rather than the climate impact and fossil fuel connection of the industry.

In Scotland, where Extinction Rebellion protesters in 2020 blocked the entrance to the integrated petrochemical production and oil refinery complex owned by INEOS. They accused the manufacturer of being Scotland’s largest contributor to climate change and a major hurdle for the government’s net zero carbon emissions target.

INEOS responded saying emissions from the production in the UK were lower than elsewhere, and that the company explores ways of reducing emissions further.

The local union, Unite, has a long history of conflicts with the owner, including on the topic of fracking. INEOS already imports ethane from US shale gas and has pursued fracking in the UK, whereas Unite has campaigned against fracking.

Striking a balance between securing jobs for the communities around petrochemical clusters and shutting down emissions-intensive production remains difficult.

So local pressure on petrochemicals has, in some cases, resulted in individual plants being forced to change their practices.

But they have not led to a systemic change of the sector, which continues to be locked in to fossil-based and greenhouse emissions intensive technologies and processes.

Every week we spend researching the topic we seem to read more news about plans for new fossil-based production facilities somewhere in the world.


The industry is not doing enough. Only a few of the large companies have set proper targets for reducing their greenhouse gas emissions. And plans for how they will do so remain light on detail.

Several scenarios show deep cuts to emissions within the industry are possible – but rely heavily on niche and future technologies that would require an unprecedented technology scale-up and renewable energy deployment.

Some large firms are strategically acquiring renewable energy assets, such as offshore wind farms, to supply energy to their plants, but not yet at anywhere near the scale needed to replace all their fossil energy use.

And industry trade associations continue to lobby against tougher regulations aimed at accelerating the transition.

At the same time, large firms continue to announce plans for new larger plants that will continue to use fossil fuel resources and remain productive for decades, emitting CO2 far beyond 2050.

There is a great need to move beyond words and small incremental changes and take larger steps towards low-carbon and sustainable plastics. Working seriously on how to get there entails many different changes.

The industry must trust and plan for a future in which the majority of plastics will be produced from recycled rather than virgin material. Virgin materials used should come from sustainably sourced biomass and other alternative feedstocks, and all energy used must be low-carbon.

Carbon capture could be a solution for the remaining fossil-based production and emissions which cannot be mitigated soon enough – including from chemical recycling plants.

At the top of their list should be collaborating with partners throughout the industry as well as researchers, decision-makers, consumers, and civil society to produce reliable roadmaps and strategies on how to transition towards a sustainable plastic system.

A convention on plastic pollution is emerging, but global meetings on climate change, such as COP26, need to focus more attention on the somewhat overseen issue of petrochemicals.

Meanwhile, at Yushan island, tankers with crude oil from Saudi Arabia will dock regularly and pump their cargo into steam crackers running 24/7 for decades. Naming it Green Petrochemical Base does nothing to change the fundamentals of the industry and its modus operandi.

Plastics are locked into fossil resources and this connection continues to grow stronger by the day.
