Definitions and Cautionary note
Definitions and Cautionary note
WARNING - UNCERTAINTIES AHEAD: Shell’s scenarios are not intended to be projections or forecasts of the future. Shell’s scenarios, including the scenarios contained in this content, are not Shell’s strategy or business plan. They are designed to stretch management to consider even events that may only be remotely possible. Scenarios, therefore, are not intended to be predictions of likely future events or outcomes and investors should not rely on them when making an investment decision with regard to Shell plc securities When developing Shell’s strategy, our scenarios are one of many variables that we consider. Ultimately, whether society meets its goal to decarbonise is not within Shell’s control, only governments can create the framework necessary for society to meet the Paris Agreement’s goals. The Sky 2050 scenario is a normative scenario, which means we assume that society meets the most ambitious goal of the Paris agreement: limiting the increase in global average temperatures to 1.5°C above pre-industrial levels this century and then we work back in presenting how this may occur. Our assumptions, for the Sky 2050 are based on what we believe are technically possible as of today and not necessarily plausible. Our Archipelagos scenario is an explorative scenario, which means we do not assume the final outcome rather we use plausible assumptions based on the data to determine what we believe will occur in the future. Of course, there is a range of possible paths in detail that society could take to achieve this goal. Although achieving the goal of the Paris Agreement and the future depicted in Sky 2050 while maintaining a growing global economy will be extremely challenging, today there is still a technically possible path. However, we believe the window for success is quickly closing.

Forward-looking statements include, among other things, statements concerning the potential exposure of Shell to market risks and statements expressing management’s expectations, beliefs, estimates, forecasts, projections and assumptions. These forward-looking statements are identified by their use of terms and phrases such as “aim”; “ambition”; ‘‘anticipate’’; ‘‘believe’’; “commit”; “commitment”; ‘‘could’’; ‘‘estimate’’; ‘‘expect’’; ‘‘goals’’; ‘‘intend’’; ‘‘may’’; “milestones”; ‘‘objectives’’; ‘‘outlook’’; ‘‘plan’’; ‘‘probably’’; ‘‘project’’; ‘‘risks’’; “schedule”; ‘‘seek’’; ‘‘should’’; ‘‘target’’; ‘‘will’’; “would” and similar terms and phrases. There are a number of factors that could affect the future operations of Shell and could cause those results to differ materially from those expressed in the forward-looking statements included in this content, including (without limitation): (a) price fluctuations in crude oil and natural gas; (b) changes in demand for Shell’s products; (c) currency fluctuations; (d) drilling and production results; (e) reserves estimates; (f) loss of market share and industry competition; (g) environmental and physical risks; (h) risks associated with the identification of suitable potential acquisition properties and targets, and successful negotiation and completion of such transactions; (i) the risk of doing business in developing countries and countries subject to international sanctions; (j) legislative, judicial, fiscal and regulatory developments including regulatory measures addressing climate change; (k) economic and financial market conditions in various countries and regions; (l) political risks, including the risks of expropriation and renegotiation of the terms of contracts with governmental entities, delays or advancements in the approval of projects and delays in the reimbursement for shared costs; (m) risks associated with the impact of pandemics, such as the COVID-19 (coronavirus) outbreak, regional conflicts, such as the Russia-Ukraine war, and a significant cybersecurity breach; and (n) changes in trading conditions. No assurance is provided that future dividend payments will match or exceed previous dividend payments. All forward-looking statements contained in this content are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Readers should not place undue reliance on forward-looking statements. Additional risk factors that may affect future results are contained in Shell plc’s Form 20-F for the year ended December 31, 2023 (available at www.shell.com/investors/news-and-filings/sec-filings.html and www.sec.gov). These risk factors also expressly qualify all forward-looking statements contained in this content and should be considered by the reader. Each forward-looking statement speaks only as of the date of this content March 21, 2023. Neither Shell plc nor any of its subsidiaries undertake any obligation to publicly update or revise any forward-looking statement as a result of new information, future events or other information. In light of these risks, results could differ materially from those stated, implied or inferred from the forward-looking statements contained in this content.
Shell’s Net Carbon Intensity
Also, in this content we may refer to Shell’s “Net Carbon Intensity” (NCI), which includes Shell’s carbon emissions from the production of our energy products, our suppliers’ carbon emissions in supplying energy for that production and our customers’ carbon emissions associated with their use of the energy products we sell. Shell’s NCI also includes the emissions associated with the production and use of energy products produced by others which Shell purchases for resale. Shell only controls its own emissions. The use of the terms Shell’s “Net Carbon Intensity” or NCI are for convenience only and not intended to suggest these emissions are those of Shell plc or its subsidiaries.
Shell’s net-zero emissions target
Shell’s operating plan, outlook and budgets are forecasted for a ten-year period and are updated every year. They reflect the current economic environment and what we can reasonably expect to see over the next ten years. Accordingly, they reflect our Scope 1, Scope 2 and NCI targets over the next ten years. However, Shell’s operating plans cannot reflect our 2050 net-zero emissions target, as this target is currently outside our planning period. In the future, as society moves towards net-zero emissions, we expect Shell’s operating plans to reflect this movement. However, if society is not net zero in 2050, as of today, there would be significant risk that Shell may not meet this target.
Forward-Looking non-GAAP measures
This content may contain certain forward-looking non-GAAP measures such as [cash capital expenditure] and [divestments]. We are unable to provide a reconciliation of these forward-looking non-GAAP measures to the most comparable GAAP financial measures because certain information needed to reconcile those non-GAAP measures to the most comparable GAAP financial measures is dependent on future events some of which are outside the control of Shell, such as oil and gas prices, interest rates and exchange rates. Moreover, estimating such GAAP measures with the required precision necessary to provide a meaningful reconciliation is extremely difficult and could not be accomplished without unreasonable effort. Non-GAAP measures in respect of future periods which cannot be reconciled to the most comparable GAAP financial measure are calculated in a manner which is consistent with the accounting policies applied in Shell plc’s consolidated financial statements.
