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.

OGCI Performance Data 2020

OGCI and its member companies have continued to assess their reporting framework both for external and internal performance indicators. We have worked this year to improve our understanding of the trends behind the aggregate performance data and increase its reliability. Our focus has been on three key areas:


  1. Understanding the impact of the Covid-19 pandemic on the performance, in order to distinguish between temporary trends and sustainable shifts in performance due to member company actions.
  2. Analyzing more deeply the impact of specific actions such as flaring and venting reduction projects, leak detection and repair campaigns, electrification of assets and asset portfolio change.
  3. Continuing our work with EY, as an independent third party, to expand the limited assurance statement for a set of aggregate data – reviewing and testing member company data and checking for third-party assurance.


OGCI data is collected and reviewed by EY as an independent third party. In 2021, EY issued a limited assurance statement (see page 6), covering eight companies.


Our member companies’ reporting methodologies are continually improved. As a result, some methodological changes have been incorporated for 2018 and 2019 in the published data, which may now differ slightly from those previously reported. Data for 2017 was updated in 2020.

The aggregate oil and gas production of the 12 OGCI member companies fell by 2% in 2020 to 45.2 Mboe/day, largely driven by reduced oil production due to the impact of the Covid-19 pandemic on demand. Without those companies with major acquisitions in 2019 and 2020, the drop would have been 3%. Oil production fell by 2% to 29.3 Mboe/day, while gas production remained stable at 15.9 Mboe/day, raising the share of gas to just over 35% of aggregate oil and gas production.

OGCI member companies operated 28% of global oil and gas production in 2020.1

OGCI member companies’ share of total oil and gas production is 28% on an operated basis and 26% on an equity basis. OGCI production data is included up until first point of sale, including LNG liquefaction plants if located before the first point of sale.

Greenhouse gas emissions

Upstream carbon intensity fell by 8% in 2020 to 19.5 kg/boe – below the initial 2025 target of 20kg. While some of that reduction in greenhouse gas emissions is a result of falling production levels due to Covid-19, member companies also report impact from electrification of assets, flaring reduction projects, portfolio changes and methane emission reduction.

While collecting greenhouse gas and production data from member companies, EY ran an exercise this year to verify that the progress in reducing emissions is sustainable as demand rebounds. The result of this work has encouraged OGCI to sharpen its 2025 target to 17 kg CO2e/boe by 2025. Compared to the 2017 baseline, upstream carbon intensity has fallen by 14%.

Aggregate absolute Scope 1 greenhouse gas emissions, both upstream and downstream, fell by 7% in 2020 and by 11% from 2017. At 632 MtCO2e, they represent 1.1% of global greenhouse gas emissions, using 2019 data from the UNEP’s Emissions Gap Report 2020 (or 1.2% using 2019 OGCI data to discount any distortion due to Covid-19 reductions). Upstream emissions represent just under half of total aggregate Scope 1 emissions.

  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

For 2020, OGCI reported an aggregate methane intensity of 0.20%, meeting the initial 2025 ambition. This progress means that collective methane intensity has fallen by 33% since 2017, with an improvement of 13% in 2020 alone. The fall in methane intensity is matched by a concomitant reduction in absolute upstream methane emissions which are now at 1.3 Mt, down from 2.0 Mt in 2017 – a reduction of 35%. Taken together, absolute upstream and downstream methane emissions fell by 33% over the three years, although reductions in downstream emissions in 2020 were also a result of refinery closures during the Covid-19 pandemic.

Upstream methane emissions reductions in 2020 came from venting (through equipment upgrades) and flaring. Extensive leak detection and repair campaigns also resulted in a continued reduction in fugitive leaks. Venting and fugitive leaks accounted for over 60% of upstream methane emissions in 2020. The upstream sector accounted for over 92% of OGCI aggregate methane emissions in 2020. Member companies are continuing their efforts to reach near zero emissions, aiming for well below 0.20% by 2025.

Upstream methane intensity


OGCI member companies made progress in reducing flaring in 2020, linked to efforts to end routine flaring by 2030. Upstream flaring intensity fell by 21% in 2020 and by 33% since 2017, reflected in falling emissions from flaring. This progress was primarily linked to significant flare reduction projects. Routine flaring volumes, specifically, dropped by 15% in 2020, despite data including one additional company.

Investment and R&D in low carbon technologies

Member companies are still working to aggregate homogenous data on low carbon investment and R&D, so the OGCI aggregate numbers do not include all companies. Those that reported spent a total of US$7.4 billion on low carbon technologies in 2020, with just over 70% spent on renewable energies. Investment in low carbon energy projects and acquisitions increased by 18% in 2020 – with a 45% increase in acquisition spending. R&D spending dropped sharply overall in 2020 because of the pandemic. Low-carbon R&D spending fell by 20% compared to 2019, but its share of total R&D spend remained relatively stable at 14%, compared to 15% in 2019.
