The global ethylene market is growing steadily and is further expected to grow significantly at a CAGR of 2.5% over 2026 to 2030. China is set to dominate global ethylene through 2030, driven by its vast manufacturing base and its burgeoning domestic demand for ethylene derivatives.
In 2026, China is likely to account for about 30% of global ethylene demand. The country’s booming packaging, construction, automotive, and consumer goods sectors feed insatiable demand for ethylene derivatives, especially polyethylene (PE), which makes up nearly two-thirds of global ethylene consumption. To support this, China has constructed advanced plants using both naphtha and coal-to-olefins processes, increasing its self-sufficiency and reducing the need for imports.

China is shifting from being a major importer to being a self-sufficient producer of ethylene, aiming to reduce dependence on foreign polymers, which further drives significant domestic demand. In addition, the rapid expansion of new energy industries, including electric vehicles (EVs), wind power, and photovoltaics, drives demand for specialised ethylene derivatives such as photovoltaic-grade EVA and PE elastomers.
Following China, the US and Saudi Arabia remain significant drivers of global ethylene demand. Strong domestic manufacturing and consumption of PE primarily drives demand in the US, while Saudi Arabia’s demand is fuelled by the rapid expansion of its downstream petrochemical sector and exports of derivatives such as PE and monoethylene glycol to international markets, especially Asia.
