Scope 1, Scope 2 and Scope 3 emissions and related risks

In assessing progress against our target to be a net-zero emissions energy business by 2050, we report our performance against our Scope 1 and 2, and Scope 3 emissions.

Shell's absolute emissions in 2023

In 2023, our total combined Scope 1 and 2 absolute GHG emissions (from assets and activities under our operational control) were 57 million tonnes on a carbon dioxide equivalent basis (CO2e), a 2% reduction compared with 2022, and a 31% reduction compared with 2016, the base year for our target. Scope 3 emissions associated with our energy product sales were 1,147 million tonnes CO2e.

[C]

Indirect GHG emissions (Scope 3, Categories 1, 3, 9 and 11) based on the energy product sales included in NCI using equity boundary. There was a decrease in reported volumes associated with additional contracts being classified as held for trading purposes with effect from January 2020. We estimate that netting of oil products sales volumes resulted in a reduction in GHG emissions of around 73 million tonnes CO2e in 2021 compared with 2016.

[D]

Emissions are reported gross without the inclusion of carbon credits.

[E]

Oil and gas industry guidelines from IPIECA indicate that several sources of uncertainty can contribute to the overall uncertainty of a corporate emissions inventory. We have estimated the overall uncertainty for our direct GHG emissions (Scope 1) to be around 4% and for our energy indirect GHG emissions (Scope 2) to be around 8% for the market-based method and 7% for the location-based method for 2023. IPIECA also notes that due to the diversity of Scope 3 emissions, sources and the fact that these emissions occur outside the company's boundaries, the emissions estimates may be less accurate or may have a high uncertainty.

[F]

Figures disclosed are rounded. Rounding differences can occur between the total combined Scope 1 and 2 absolute GHG emissions disclosed in this Report and the sum of its components individually rounded to the nearest million tonnes.

[G]

Acquisitions and divestments have been included in the actual performance tracking with the target unchanged. Note that acquisitions and divestments could have a material impact on meeting the targets.

Drivers of Scope 1 and 2 emissions

Our direct GHG emissions (Scope 1, operational control boundary) decreased from 51 million tonnes of carbon dioxide equivalent (CO2e) in 2022 to 50 million tonnes CO2e in 2023, driven by several factors including:

  • divestments in 2022 (e.g. Deer Park and Mobile refinery, Tunisia Miskar concession, offshore Baram Delta Operations (BDO) PSC and Block SK307 PSC in the Philippines) and handover of operations in OML 11 in Nigeria in 2022;
  • unplanned downtime (e.g. Deer Park Chemicals);
  • reduced flaring from assets including Shell Nigeria Exploration and Production Company (SNEPCo);
  • reduction activities (see examples in the list of energy efficiency projects below) and purchase of renewable electricity.

These decreases were partly offset by Shell Polymers Monaca having more units online in 2023 and higher emissions from Pearl and Prelude with increased production.

Routine flaring of gas occurs during normal oil production if it is not possible to use the gas or reinject it into the well.

Total routine flaring from our upstream oil and gas assets remained relatively stable in 2023 compared with 2022 at 0.1 million tonnes, having reduced from 1.1 million tonnes in 2016.

Around 50% of total routine and non-routine flaring in our Integrated Gas and Upstream facilities in 2023 occurred in assets operated by the Shell Petroleum Development Company of Nigeria Limited (SPDC) and SNEPCo.

On January 16, 2024, Shell reached an agreement to sell SPDC to Renaissance, a consortium of five companies, subject to approvals by the Federal Government of Nigeria and other conditions. SPDC will continue to operate the SPDC joint venture (SPDC JV [A]) on behalf of all the joint-venture partners, who together will continue to make decisions relating to work programmes for the SPDC JV's assets and infrastructure. This includes work programmes to eliminate routine flaring.

[A] The SPDC JV comprises SPDC Ltd (30%), the government-owned NNPC (55%), Total Exploration and Production Nigeria Ltd (10%) and Nigeria Agip Oil Company Ltd (5%).

Methane emissions intensity from all oil and gas assets for which Shell is the operator that market their gas (incl. LNG and GTL assets), defined as the total volume of methane emissions in normal cubic metre (Nm3) per total volume of gas available for sale in Nm3.

[B]

Methane emissions intensity from all oil and gas assets for which Shell is the operator that do not market their gas (e.g. where gas is reinjected) defined as the total mass of methane emissions in tonnes per total mass of oil and condensate available for sale in tonnes.

[C]

Total methane emissions for all assets under Shell operational control including Integrated Gas and Upstream and Downstream and Renewables and Energy Solutions assets, quantified according to industry best practice.

Our target to keep methane emissions intensity below 0.2% was met in 2023 with Shell's overall methane emissions intensity at 0.05% for facilities with marketed gas and 0.001% for facilities without marketed gas.

In 2023, Shell's total methane emissions were 41 thousand tonnes compared with 40 thousand tonnes in 2022. The increase was due to venting (e.g. the maintenance of our Floating LNG Prelude asset and operational issues in assets operated by Sarawak Shell Berhad) and an increase in reported emissions from integrated gas assets in Canada resulting from the adoption of enhanced source-level measurements in line with The Oil and Gas Methane Partnership (OGMP) reporting requirements.

We believe our methane emissions are quantified according to industry best practice. Methane emissions include those from unintentional leaks, venting and incomplete combustion, for example in flares and turbines.
