Scope 1, 2 and 3 Emissions Explained

If you've started thinking seriously about your organisation's carbon footprint, you've almost certainly come across the terms Scope 1, 2 and 3. Here's what they actually mean, why the distinction matters, and what it looks like in practice for events and touring businesses.

‍

The Greenhouse Gas Protocol, the most widely used international framework for measuring carbon emissions, divides emissions into three categories, or "scopes". Each scope covers a different part of an organisation's carbon footprint, and understanding the difference is the foundation of any serious sustainability strategy.

What are Scope 1 emissions?

Scope 1 covers direct emissions from sources that your organisation owns or controls. These are the emissions you produce yourself, directly, as a result of your activities.

Scope 1 is typically the easiest category to measure and often the most straightforward to reduce, because you have direct control over the sources involved. Switching from diesel generators to cleaner alternatives is a Scope 1 intervention.

What are Scope 2 emissions?

Scope 2 covers indirect emissions from the generation of electricity, heat, or cooling that your organisation purchases and uses. The emissions aren't produced on your premises, but they are a consequence of your energy consumption.

As energy grids get cleaner, Scope 2 emissions from grid electricity are falling in many markets. But the rate of that transition varies significantly by country and region, which matters a great deal for international touring.

What are Scope 3 emissions?

Scope 3 is the broadest category, covering all other indirect emissions that occur across your value chain, both upstream (your supply chain) and downstream (what happens as a result of your activities). For most organisations, Scope 3 is also the largest category by far.

Scope 3 is harder to measure precisely because it requires data from third parties, but that difficulty is not a reason to ignore it. For events businesses, ignoring Scope 3 means ignoring the overwhelming majority of your actual footprint.

Why do the scopes matter for my organisation?

The scopes exist to give organisations a common language for discussing and reporting emissions, and to prevent double counting across supply chains. When one company's Scope 3 emissions are another company's Scope 1, the framework makes it possible to trace emissions back to their source.

More practically, understanding the scopes helps you prioritise. If your Scope 3 audience travel emissions are ten times the size of your Scope 1 and 2 combined, that tells you something important about where to focus your reduction efforts. If your Scope 1 is dominated by diesel generation, that's a different conversation to have.

Increasingly, organisations are also being asked by funders, partners, sponsors, and regulators to report across all three scopes. A Scope 1 and 2 only position is no longer considered a complete picture.

What does a complete carbon footprint assessment cover?

A robust carbon footprint assessment for a tour or event will cover all three scopes, weighted by relevance to your specific activities. For a live music context, that typically means modelling audience travel (usually Scope 3 category 11 or 12), production energy (Scope 1 and 2), band and crew travel (Scope 3), freight and logistics, and supply chain contributions from key contractors.

The goal is not perfection in the first instance. It's establishing a baseline that is honest, consistent, and comparable over time. You cannot improve what you haven't measured.

What's the relationship between the scopes and net zero commitments?

Any credible net zero commitment needs to address all three scopes. A target that only covers Scope 1 and 2 is not a net zero target: it's a partial one. Science-based targets, the gold standard for corporate climate commitments, require Scope 3 to be included where it is material to an organisation's footprint.

For events and touring businesses, Scope 3 is almost always material. That means building the data infrastructure to measure and track it is not optional if you want to make claims that hold up to scrutiny.

How are the scopes used in reporting frameworks?

The GHG Protocol scopes underpin almost every major voluntary and mandatory reporting framework in use today. CDP (formerly the Carbon Disclosure Project), which thousands of companies disclose through annually, requires Scope 1, 2 and 3 reporting as standard. The Global Reporting Initiative (GRI) standards, widely used across the events and creative industries, reference the same three categories.

In the UK, Streamlined Energy and Carbon Reporting (SECR) requires large companies to report Scope 1 and 2 as a minimum, with Scope 3 strongly encouraged. Science Based Targets initiative (SBTi) commitments (increasingly a requirement for companies wanting credible net zero claims) mandate Scope 3 inclusion where it accounts for more than 40% of total emissions. For most events and touring businesses, it will. Understanding the scopes is therefore not just useful internally. It's the foundation for any external reporting you'll be asked to do as disclosure expectations continue to tighten.

What's the most common mistake organisations make with the scopes?

The most common mistake is treating Scope 1 and 2 reductions as a complete sustainability story. Switching to renewable energy tariffs or eliminating diesel from your own operations are meaningful steps, but if your Scope 3 (particularly audience travel) remains unmeasured and unaddressed, you are reporting on a fraction of your actual footprint.

A second common error is measuring the scopes inconsistently from one year to the next, making it impossible to demonstrate genuine progress over time. Baseline year, methodology, and scope boundary need to stay consistent if your numbers are to mean anything. A third is confusing carbon offsetting with reduction. Offsets have a role, but purchasing credits to cover emissions you haven't measured or tried to reduce does not constitute a credible net zero position. The scopes framework exists precisely to make these distinctions clear, and to make it harder to hide behind incomplete or inconsistent reporting.
