Greenhouse gas emissions GHGs
The direct greenhouse gas (GHG) emissions from facilities we operate were 71 million tonnes on a CO2-equivalent basis in 2018, down from 73 million tonnes of CO2 equivalent in 2017.
The main contributors to this decrease were divestments (for example, in Argentina, Canada, Gabon, Iraq, Malaysia and the UK). The level of flaring in our Upstream and Integrated Gas businesses combined decreased by more than 35%, compared to 2017, primarily as a result of the Majnoon divestment in Iraq. These decreases were partly offset by inclusion of the facilities previously operated by the Motiva Enterprises LLC joint venture in our data for the full year in 2018, increased production at our Pearl gas-to-liquids (GTL) plant in Qatar, and the start-up of our Prelude floating liquefied natural gas (FLNG) facility in Australia.
The indirect GHG emissions from the energy we purchased (electricity, heat and steam) were 11 million tonnes on a CO2-equivalent basis in 2018, down from 12 million tonnes of CO2 equivalent in 2017. These emissions were calculated using a market-based method, as defined by the World Resources Institute GHG Protocol.
We expect that maintaining the energy efficiency levels of recent years will be more difficult in the future as existing fields age and new production comes from more energy-intensive sources. This could result in an associated increase in direct GHG emissions from our upstream facilities over time.
We use global warming potentials (GWP) from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change on a 100 years time horizon for calculating GHG emissions since 2015. GWP compares the impact of emissions from GHGs with the impact of emissions from the equivalent amount of CO2.
For information on the limitations of our GHG data see the GHG Assurance tab.
We have achieved external verification of our 2018 direct and energy indirect GHG data from facilities we operate.
See our GHG Assurance tab for more details.

Emissions by boundary and scope
Below we report emissions on an operational control (100% of emission from companies and joint ventures where we are the operator) and equity basis (equity share of emissions from companies and joint ventures).
The direct (Scope 1) emissions come from the facilities under the operational control or the equity boundary. The energy indirect (scope 2) emissions come from the facilities of others that provide electricity or heat and steam to our operations.
(million tonne CO2 equivalent)
Control - 2017
Control - 2018
|Equity - 2017||Equity – 2018|
|Direct (Scope 1)||73||71||97||95|
|Energy indirect (Scope 2)||12||11||13||11|
Scope 3 emissions are those emissions that we estimate come from the use of our refinery and natural gas products as reported in the Annual Report.
|Scope||Annual Report boundary||Annual Report boundary|
|million tonne CO2||2017||2018|
|Use of our refinery and natural gas products (Scope 3)||579||599|
Emissions by business sector
Here we report the breakdown of emissions by business sector. These are the direct and energy indirect emissions on both an operational control and equity basis reported in million tonnes CO2 equivalent.
Direct (Scope 1)
Equity - 2017
|Equity – 2018|
|Downstream (including shipping and oil sands)||41.1||42.2||47.1||47.1|
|Integrated Gas & New Technologies||12.0||13.0||24.1||25.3|
Energy Indirect (Scope 2)
Equity - 2017
|Equity – 2018|
|Downstream (including shipping and oil sands)||7.5||6.8||9.2||7.9|
|Integrated Gas & New Technologies||2.4||2.4||2.0||1.9|
Below we report emission intensities for Upstream and Integrated Gas, refining and chemical facilities under our operational control (100% of direct and energy indirect GHG emissions normalised by an appropriate production value).
|Emissions Intensity||Units of measure||2017||2018|
|Upstream and Integrated Gas [A]||Tonne CO2 equivalent / tonne of hydrocarbon production available for sale||0.166||0.158|
|Chemicals [B]||Tonne CO2 equivalent / tonne of steam cracker high value chemicals produced||0.95||0.96|
|Refineries [C]||Tonne CO2 equivalent / UEDCTM||1.14||1.05|
[A] In tonnes of total direct and energy indirect GHG emissions per tonne of oil and gas available for sale, liquefied natural gas and gas-to-liquids production in Integrated Gas and Upstream.
[B] High value chemicals include olefin products (ethylene and propylene) plus the contained butadiene, benzene, acetylene, and high purity hydrogen production.
[C] UEDCTM (Utilised Equivalent Distillation Capacity) is a proprietary metric of Solomon Associates. It is a complexity-weighted normalisation parameter that reflects the operating cost intensity of a refinery based on size and configuration of its particular mix of process and non-process facilities.
We undertake external verification of our operational control and equity GHG data to a level of limited assurance at the Shell Group and business level. The operational control verification for the previous year’s data is undertaken in February and the equity work is undertaken in May. The assurance statements become available in March and June respectively.
In addition, we undertake external verification to a level of reasonable assurance at the major installations where we have operational control. These audits are conducted under the local regulated scheme or, in the absence of regulation, under Shell’s own program which uses external auditors from a variety of organisations.
Challenges with equity data
Approximately one quarter of the equity data comes from sources outside our data systems and carries potentially greater uncertainty. The quantification and hence verification of equity emissions takes longer than operational control emissions as we are dependent on receiving data from other parties and reporting timelines vary.
Net Carbon Footprint Assurance
The Net Carbon Footprint (NCF) is determined by first estimating the emissions intensity for each of the energy product supply chains in Shell’s portfolio; this is done using established lifecycle analysis principles and includes both the emissions associated with the production and processing of energy products and the emissions associated with their use. The individual intensities are then aggregated into a single value, with the weighting for each product determined by its sales volume, emissions captured in sinks are deducted to give the final net value.
Shell’s Net Carbon Footprint values for 2016, 2017 and 2018 are shown in the assurance statements below. We express our Net Carbon Footprint as the grams of CO2 equivalent per megajoule (gCO2e/MJ) produced for each unit of energy delivered to, and used by, a consumer.
We undertake external verification of our Net Carbon Footprint values to a level of limited assurance at the Shell Group level. This external verification takes place around February. The assurance statements become available in March.
Shell welcomes the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD)
The TCFD is a global initiative to get companies across all sectors to assess climate-related risks and opportunities. It recommends that companies disclose information in four areas: Governance, Strategy, Risk Management, Targets and Metrics. Shell supports the work and objectives of the TCFD.
Shell discloses TCFD-relevant information through different channels:
- The Shell Annual Report/20-F provides information on our governance and risk management of climate change.
- Our Shell Energy Transitions Report describes our strategy to remain resilient and thrive through climate-related risks and opportunities.
- The annual Shell Sustainability Report publishes relevant climate-related emissions performance data.
- Periodic Shell scenario publications share our analysis and understanding of the ways the energy system could evolve over the long term.
- Our company website contains further relevant information such as equity emissions performance data, executive speeches, feature articles and news items.
This table shows where to find Shell disclosures that are related to recommendations by the TCFD in Shell reports, publications and websites:
