Shell’s Stable Emissions and the Limits of Carbon Intensity Metrics

Introduction

The latest annual report of Shell plc highlights that its total emissions remained broadly stable at around 1.1 billion tonnes CO₂ equivalent in 2025, raising important questions about the effectiveness of intensity-based climate strategies in reducing absolute emissions.

Analysis

Emissions Profile and Scale

Shell reported ~1.1 billion tonnes CO₂ equivalent emissions in 2025, indicating no significant decline despite ongoing energy transition efforts. For comparison, the United Kingdom’s total emissions (~480 million tonnes CO₂e in 2024) are less than half of Shell’s footprint, underlining the massive scale of emissions from global energy corporations.A key structural feature of Shell’s emissions is the dominance of Scope 3 emissions, which arise primarily from the combustion of fuels sold by the company. This highlights that end-use consumption, rather than production alone, drives the majority of emissions in fossil fuel value chains.

Carbon Intensity vs Absolute Emissions

Shell uses Net Carbon Intensity (NCI) as its primary metric:

• NCI in 2025: 71 g CO₂e per megajoule (unchanged from 2024)
• Long-term target: Net zero NCI by 2050

However, the article highlights a critical limitation:

• Carbon intensity metrics allow emissions efficiency improvements without reducing total emissions
• Companies can:
  • Increase fossil fuel output
  • Use offsets, biofuels, or renewables
  • Still maintain or reduce intensity values

This creates a disconnect between reported progress and real climate impact, as absolute emissions may remain stable or even rise.

Structural Challenge in Energy Transition

The persistence of high emissions reflects:

• Continued global dependence on fossil fuels
• Difficulty in reducing Scope 3 emissions, which are largely outside direct operational control
• Reliance on market-based adjustments (offsets, fuel mix changes) rather than deep structural transformation

This reinforces a key climate debate:

Should climate targets prioritise intensity reduction or absolute emission cuts?

Implications for Climate Policy and Corporate Accountability

The case of Shell illustrates broader systemic issues:

• Intensity-based targets may mask real emission trends
• Corporate climate strategies may appear aligned with net zero goals without delivering substantial emission reductions
• Policymakers may need to:
  • Emphasise absolute emission caps
  • Strengthen Scope 3 accountability frameworks

Key Concepts

• Scope 3 Emissions: Indirect emissions from use of sold products
• Net Carbon Intensity (NCI): Emissions per unit of energy supplied
• Decoupling Issue: Intensity ↓ but total emissions ↔ or ↑

Shell plc

• Type: Global energy and petrochemical company
• Headquarters: London, United Kingdom (as per article context)
• Function: Exploration, production, refining and sale of energy products
• Climate Strategy: Focus on Net Carbon Intensity reduction to zero by 2050

Conclusion

Shell’s emissions profile demonstrates that stability in emissions alongside unchanged carbon intensity highlights the limitations of intensity-based climate metrics. The case underscores the need for a shift toward absolute emission reductions to achieve meaningful progress in global climate mitigation.
