How Solar Can Help You Meet Scope 2 & 3 Targets

Understanding and managing your organisation’s carbon footprint is now an essential part of running a responsible business. Many companies have already begun addressing Scope 3 emissions, which often make up the largest and most complex share of total emissions.

Yet Scope 2 emissions, which come from the electricity, heat, or cooling that your business purchases, are just as important when it comes to setting and reaching meaningful sustainability targets. Purchased energy can account for up to 40% of total emissions in office environments alone.

Investing in renewable energy, such as an on-site solar PV system, remains one of the most effective ways to cut these emissions. When planned properly, it helps you take immediate control of your purchased energy use and supports your wider sustainability strategy and stakeholder credibility.

What Are Scope 2 Emissions?

Scope 2 emissions are the indirect greenhouse gas emissions that come from the energy your business buys and uses on site. This includes purchased electricity, heating, cooling or steam. For most organisations, these emissions make up a significant share of their total carbon footprint, second only to the direct emissions they produce themselves.

Unlike Scope 1, which covers fuel burned on site or in company-owned vehicles, Scope 2 is all about what happens when you switch on the lights, run your machinery or heat your buildings with energy supplied by an external provider. According to the International Energy Agency, indirect emissions from the electricity and heat used in buildings account for around 18% of global energy-related CO₂ emissions.

Switching to renewable energy sources, such as installing your own solar PV, is one of the most direct and proven ways to reduce Scope 2 emissions. By generating clean power on site, businesses rely less on fossil-fuelled grid electricity and make measurable progress towards their carbon reduction goals.

How to Measure Scope 2 & 3 Emissions

For businesses, the first step to realistic carbon reduction goals is to measure their emissions properly.

For Scope 2, the process starts by gathering electricity and heating bills. Installing smart meters can provide more detailed data for a clearer view. Furthermore, the UK Government conversion factors are designed to help turn energy use into carbon figures.

Scope 3 is broader, as it covers everything that happens across the wider value chain. This can include waste disposal, supplier operations, and business travel. To get a clear picture, businesses often start with a simple materiality check, then build more accurate data over time. A clear carbon accounting plan is instrumental to track progress and keep reporting consistent.

Working Out Your Targets

Scope 2 and 3 figures help set targets that are realistic and achievable. Recognised frameworks, such as the Science Based Targets initiative, can be part of the strategy. These help make sure plans match wider climate standards and meet growing expectations from both customers and investors.

Targets need to be based on real data at all times as this avoids under- or overestimating the real energy use; it also makes it easier to track improvements. A professional solar consultancy can help define the right design, technology and installation with minimal disruption to daily operations.

Many UK businesses also explore government-backed incentives or grants to help offset the cost of renewable energy installations. Availability may vary depending on sector, location, and project size.

How Solar Can Help You Meet Scope 2 & 3 Targets

On-site solar panels are one of the most effective ways to cut Scope 2 emissions. By generating clean electricity through a solar PV system, businesses rely less on grid power, which is still largely produced from fossil fuels. This reduces indirect emissions and lowers long-term energy costs simultaneously.

Solar can also help with certain Scope 3 emissions:

• Choosing renewable energy supports a greener supply chain
• It sends a positive message to partners and customers
• It can influence suppliers to reduce emissions across your wider network

It’s worth noting that commercial solar PV systems can deliver an annual return on investment of around 25 to 35%, helping secure predictable savings for years to come.
