GHG emissions of largest global oil companies 2022
The Chinese state-owned oil and gas producer Sinopec's direct greenhouse gas emissions (Scope 1) amounted to 138 million metric tons of carbon dioxide equivalent (MtCO₂e) in 2022. This was a more than any other major oil company's direct emissions that year. PetroChina, another Chinese state-owned entity, followed closely with emissions amounting to 120 MtCO₂e.
Combined, these 10 oil majors emitted more than 700 MtCO₂e from their own operational activities. However, oil companies are responsible for far higher emissions when indirect Scope 3 emissions are taken into account. Scope 3 emissions are those that occur in sources not owned or controlled by a company, but are associated with a company's supply chain or from customers' use of their products, such as for heating buildings and transportation.
