Our aggregate data is reported annually and used to set baselines and track progress for collective targets. OGCI member companies have standardized and regularly streamline the methodologies we use to collectively report greenhouse gas emissions and spending on low carbon technologies.

EY, as an independent third party, verifies data submitted by companies, anonymizes it and reviews the consolidated data – learn more.


The aggregate oil and gas production of the 12 OGCI member companies rose by 1% in 2019, largely due to a rise in natural gas production. Operated oil production remained stable at 30 Mboe/day, while gas production rose 2% to reach 16 Mboe/day. OGCI member companies now operate 28% of global oil and gas production and represent 16% of total primary energy demand.1

Natural gas represents just over a third of OGCI member companies’ operated oil and gas portfolio, at 34% in 2019, slightly up on 2018. OGCI member companies represent almost a quarter of global natural gas production, at 23% in 2019.

Equity production is slightly lower than operated production. The share of equity production not operated by other OGCI members is around 30%.  Based on these numbers, OGCI member companies represent a total of around 36% of global oil and gas production.2

  1. According to data from IEA WEO-19, global oil and gas production in 2018 was 163 Mboe/day. Oil production in 2018 was 95 Mboe/day, while natural gas production was 68 Mboe/day. Total global energy demand in 2018 was 288 Mboe/day. OGCI member companies’ share of total oil and gas production is 28% on an operated basis and 26% on an equity basis. The share of total global energy demand is 16% on an operated basis and 15% on an equity basis. OGCI production data is counted up until first point of sale, including LNG liquefaction plants if located before the first point of sale.
  2. Total OGCI oil and production is around 59 Mboe/day (operated production plus additional equity production of around 13 Mboe/day). That is 36% of of total global oil and gas production of 163 Mboe/day.
  3. Aggregate operated data for 12 companies unless otherwise specified 

Operated production – Total output produced under a company’s control and responsibility
Equity production – Total output in operations that are owned by a company (calculated according to ownership share)
Mboe/day – Million barrels of oil equivalent per day

Greenhouse gas emissions

As preparation for launching our upstream carbon intensity target in July 2020, we further aligned our methodology for calculating operated Scope 1 and 2 greenhouse gas emissions intensity. In 2019 our upstream carbon intensity fell 5%, bringing the total reduction from the 2017 baseline to 7%. This improvement, due largely to reducing methane emissions, emissions from flaring through flare reduction and optimization, energy efficiency projects and the integration of renewables, sets us on track towards the ambitious end of our target range.

OGCI member companies’ aggregate absolute Scope 1 operated greenhouse gas emissions, both upstream and downstream, fell by 1% in 2019 and by 4% from 2017. At 678 MtCO2e, they represent 1.4% of global greenhouse gas emissions, using data from the UNEP’s Emissions Gap Report 2019. Upstream emissions represent 50% of total aggregate Scope 1 emissions.

  1. This is the key performance indicator for OGCI’s upstream carbon intensity target. It includes upstream carbon dioxide and methane emissions, both Scope 1 & 2, on an operated basis. It excludes emissions from gas liquefaction (which are largely equity rather than operated assets).
  2. This figure includes direct (Scope 1) emissions of carbon dioxide, methane and nitrous oxide (for those companies that report it) from all operated activities (upstream as well as downstream, which includes refineries and petrochemicals).
  3. Upstream activities comprise all operations from exploration to production and gas processing (up to the first point of sale), including LNG liquefaction plants if located before the first point of sale.

Methane emissions

This year we adjusted our methane intensity baseline and progress measurements to accommodate 12 rather than 13 member companies. As a result, our baseline fell from 0.32% to 0.30%. As a result, and along with data corrections for 2018, we met our initial methane intensity target in 2018. Following continued progress in 2019, we are now on track to meet our 2025 ambition of 0.20%.

Our methane intensity has fallen by 25% since 2017, with a 9% drop in 2019 to 0.23%. Absolute methane emissions, including both upstream and downstream, fell 7% over the year and 22% over two years. The greatest impact in both 2018 and 2019 came from equipment upgrades which cut leaks and reduce the need for safety venting, alongside extensive leak detection and repair campaigns. These two sources – fugitive leaks and venting – accounted for two-thirds of upstream methane emissions in 2019.

Upstream methane intensity


Upstream flaring intensity fell by 4% in 2019 and by 13% since 2017, reflected in falling emissions from flaring. This improvement was due to lower flaring volumes, linked to flare reduction projects, better compressor reliability and reduced start-up periods. Routine flaring data has been collected for the first time in 2019 – it accounted for 24% of total volumes flared for the 10 member companies that reported data in 2019.

Investment and R&D in low carbon technologies

Given the importance of monitoring performance in low carbon spending, we have clarified the definitions for collecting this information and revised past data from 2017 on this basis. The companies that provided information (10 for investment and nine for research and development (R&D)) spent a total of US$7.4 billion in low carbon technologies in 2019, an increase of 12% over the year and 35% over 2017. Of this, US$6.4 billion was spent on low carbon energy projects and acquisitions. Almost 70% of the total was spent on renewable energies, while total investment in carbon capture, use and storage (CCUS) more than doubled in 2019.

In addition, R&D spending in low carbon energy (reported by nine companies) remained at just over US$1 billion in 2019 – amounting to 17% of total R&D spend for those companies. Over a quarter of the R&D expenditures were focused on renewables and around 15% on CCUS technologies.
