Understanding the Basics of Scope 3 Emissions in Oil and Gas

Sustainability has become a top priority for the Oil and Gas industry, an essential yet highly scrutinised sector in the global economy. While much focus has historically been placed on reducing Scope 1 and Scope 2 emissions, the conversation is rapidly shifting toward Scope 3 emissions, those indirect emissions that occur across a company’s value chain. For Sustainability Managers in Oil and Gas, understanding Scope 3 emissions is crucial to developing effective strategies for mitigation and reporting.

Here’s a breakdown of what Scope 3 emissions are, why they matter, and how the Oil and Gas sector can begin to address them.

What Are Scope 3 Emissions?

The Greenhouse Gas (GHG) Protocol defines Scope 3 emissions as all indirect emissions that occur in a company’s value chain, excluding Scope 2 emissions (those from purchased electricity, steam, heating, and cooling). Scope 3 emissions encompass 15 distinct categories, divided into upstream and downstream activities. For the Oil and Gas sector, key categories include:

Upstream emissions:
Emissions from the extraction, production, and transportation of purchased goods and services.
Emissions from capital goods, such as drilling equipment or infrastructure.

Downstream emissions:
Emissions from the processing, distribution, and use of sold products (e.g., gasoline, diesel, or natural gas combustion by end-users).

Given the industry’s dependence on fossil fuels, downstream emissions from the use of sold products typically represent the largest share of Scope 3 emissions.

Why Do Scope 3 Emissions Matter?

1. Environmental Impact: Scope 3 emissions often account for the majority of an Oil and Gas company’s total GHG emissions. Addressing them is critical to meeting global climate targets such as those outlined in the Paris Agreement.
2. Regulatory Pressure: Governments and international organisations are increasingly mandating comprehensive emissions disclosures, including Scope 3, to drive transparency and accountability.
3. Investor and Stakeholder Expectations: Investors, customers, and stakeholders now demand a clear demonstration of how companies are managing their carbon footprints. Transparency on Scope 3 emissions can enhance credibility and trust.
4. Business Resilience: Measuring and reducing Scope 3 emissions can uncover opportunities for innovation, efficiency improvements, and competitive advantage in a low-carbon economy.

How to Start Measuring Scope 3 Emissions

1. Map Your Value Chain: Identify all activities and processes linked to your operations, both upstream and downstream. This helps prioritise the most material categories for your business.
2. Engage Suppliers and Partners: Collaborate with suppliers and contractors to gather data on their emissions. Sharing sustainability goals can foster joint efforts to reduce emissions across the value chain.
3. Utilise Industry-Specific Tools: Platforms like the GHG Protocol’s Scope 3 Evaluator and lifecycle assessment (LCA) tools tailored to Oil and Gas can streamline data collection and emissions quantification.
4. Apply Emission Factors: Use standard emission factors, such as those provided by the International Energy Agency (IEA) or the Environmental Protection Agency (EPA), to estimate emissions for specific activities.
5. Invest in Technology: Advanced analytics platforms and sustainability software solutions can automate data collection, calculation, and reporting, ensuring accuracy and efficiency.

Challenges in Addressing Scope 3 Emissions

1. Data Gaps: Collecting accurate and complete data across a complex value chain can be challenging, particularly when relying on external parties.
2. Lack of Standardisation: While frameworks like the GHG Protocol provide guidance, industry-specific nuances can complicate reporting and comparisons.
3. Resource Intensity: Measuring and managing Scope 3 emissions requires significant time and investment, especially for companies new to the process.

Next Steps for Oil and Gas Companies

1. Set Clear Targets: Commit to reducing Scope 3 emissions by setting science-based targets aligned with a 1.5°C pathway.
2. Integrate Sustainability Across Operations: Embed emissions reduction strategies into procurement, product design, customer engagement and employee education.
3. Report Transparently: Use recognised frameworks like CDP, GRI, or TCFD to disclose your emissions data, methodologies, and progress.
4. Leverage Collaboration: Join industry initiatives like the Oil and Gas Climate Initiative (OGCI) to share best practices and drive collective action.

Understanding and addressing Scope 3 emissions is no small task for sustainability managers in the oil and gas sector. However, by building a robust strategy that prioritises transparency, collaboration, and innovation, companies can play a pivotal role in the transition to a low-carbon future.
