Best Buy’s Rooftop Solar Initiatives: A Step Toward Net Zero

Best Buy installs solar panels on California and New York stores

Best Buy has started fitting rooftop solar systems to retail sites in California and New York. The move forms part of the company’s plan to cut operational carbon emissions by 75% by 2030 and reach net zero by 2040.

The electronics retailer set these targets in 2019, using 2009 as its baseline year. By the end of fiscal 2025, Best Buy reported a 74% reduction in carbon emissions. It now sits one percentage point away from its 2030 milestone.

This matters because large retailers consume substantial amounts of grid electricity. Consequently, their energy choices affect both climate outcomes and operating costs. For UK businesses tracking corporate climate action, Best Buy’s approach shows how retail property can generate on-site renewable power rather than relying solely on off-site arrangements.

How Best Buy structured its emissions targets

Best Buy committed to two core operational goals in 2019. First, it pledged to reduce Scope 1 and Scope 2 carbon emissions by 75% by 2030. Second, it set a carbon neutral target for 2040 across all operations.

The 2040 deadline represents an acceleration. Originally, Best Buy planned to reach carbon neutrality by 2050. It brought that target forward by ten years.

The company aligned its reduction pathway with the Science Based Targets initiative. This means its goals match the trajectory needed to limit global temperature rises to below 2°C. SBTi provides a framework that connects corporate targets to climate science.

Best Buy’s latest progress report shows it has nearly reached its 2030 goal five years early. Therefore, the rooftop solar rollout appears to support continued momentum rather than representing a late effort to close a gap.

Rooftop solar deployment in New York and California

The new installations focus on stores in two states with strong solar potential and supportive energy policies. Best Buy selected New York and California for this phase of on-site generation.

This approach differs from the company’s earlier utility-scale projects. For example, Best Buy invested in the Best Buy Solar Field in South Carolina and the Little Bear Solar Project in California. Together, these large off-site installations power nearly 1,000 stores.

Earlier projects like Prospero 2 were designed to offset the carbon impact of around 300 Best Buy stores for ten years. That equates to roughly 30% of the company’s US retail portfolio.

Best Buy plans to meet its remaining reduction requirements through several methods. These include on-site solar, renewable energy credits, hybrid vehicle fleets, and LED lighting automation. The rooftop installations add a visible, distributed element to this mix.

On-site generation offers specific advantages. It reduces transmission losses, lowers exposure to grid price volatility, and provides a customer-facing demonstration of climate action. However, rooftop solar capacity varies by building size and orientation. Not every store can host the same system scale.

Customer emission reductions and financial savings

Best Buy set a parallel goal beyond its own operations. It aims to help customers reduce their carbon emissions by 20% by 2030. The company estimates this effort could save customers $5 billion in utility costs.

This target focuses on product selection. Best Buy prioritizes Energy Star-labelled appliances and energy-efficient technology. Sales of these products reduce household electricity consumption and therefore lower customer energy bills.

For UK businesses, this model illustrates how retailers can extend their climate commitments beyond direct control. Products sold today will consume energy for years. Influencing that downstream impact creates a larger total effect than operational changes alone.

Best Buy also set waste and water targets. It aims for 85% waste diversion across US operations by 2025 and a 15% reduction in enterprise water usage by the same deadline. These goals sit alongside its carbon commitments as part of a broader environmental program.

In recognition of this work, CDP placed Best Buy on its Climate A List for the ninth consecutive year. CDP ranks companies based on climate transparency and the rigor of their reduction plans.

Why on-site solar matters for retail property

Installing panels on store rooftops marks a shift from off-site renewable energy procurement to distributed generation. Off-site utility-scale projects deliver cost efficiency and volume. On-site systems offer different benefits.

First, they reduce the energy intensity of individual buildings. Power generated on the roof does not travel through transmission infrastructure. This cuts line losses and grid charges.

Second, visible solar installations signal commitment to the communities around each store. Customers and local authorities can see the hardware. This transparency strengthens corporate reputation and may influence purchasing decisions.

Third, on-site generation provides partial resilience against grid disruptions. While most retail solar systems remain grid-tied, they can reduce reliance on external supply during peak demand periods.

For UK retailers and property owners, this approach raises questions about building suitability. Roof age, load capacity, shading, and planning permissions all affect feasibility. However, declining solar hardware costs have widened the range of viable projects.

Best Buy’s deployment also demonstrates how large companies can layer different renewable energy strategies. Utility-scale contracts provide baseline renewable power. On-site installations add local generation and visible impact. Renewable energy credits fill remaining gaps.

Key facts about Best Buy’s solar program

• Best Buy aims to cut Scope 1 and Scope 2 emissions by 75% by 2030, using a 2009 baseline.
• The company reported a 74% emissions reduction by the end of fiscal 2025, one point below its 2030 target.
• Rooftop solar installations are being deployed on retail locations in California and New York.
• Best Buy’s existing utility-scale solar projects power nearly 1,000 stores across the United States.
• The Prospero 2 solar project alone offsets emissions from approximately 300 stores for ten years.
• Best Buy has appeared on CDP’s Climate A List for nine consecutive years.
• The company targets carbon neutrality across operations by 2040, accelerated from an original 2050 goal.

What UK businesses can learn from this approach

Best Buy’s combination of on-site and off-site renewable energy offers a template for UK businesses with property portfolios. Retailers, distribution centers, and manufacturing sites with suitable roofs can consider similar strategies.

Solar installation costs in the UK have fallen significantly over the past decade. Meanwhile, grid electricity prices remain volatile. These two factors improve the financial case for on-site generation compared to ten years ago.

For businesses pursuing net zero or participating in public sector supply chains, on-site renewable generation demonstrates tangible progress. It provides evidence of direct action rather than reliance on offset credits alone. Supply chain due diligence increasingly scrutinizes the difference between these approaches.

UK companies should assess building stock systematically. Roof surveys can identify which sites offer viable solar potential. Priority should go to buildings with high daytime electricity consumption that matches solar generation patterns. Retail stores, warehouses with refrigeration, and data centers typically fit this profile.

Financing options have also expanded. Power purchase agreements allow businesses to host solar systems without upfront capital expenditure. Third-party providers own and maintain the equipment while the business buys the electricity generated. This removes barriers for companies that lack capital budgets for energy infrastructure.

Best Buy’s Science Based Targets commitment shows the importance of credible goal-setting frameworks. UK businesses facing scope 3 reporting requirements under new regulations should consider SBTi validation. It provides external verification that targets align with climate science rather than arbitrary percentages.

We work with businesses to assess the full carbon footprint of operations and identify reduction opportunities across scope 1, 2, and 3 emissions. Our net zero program helps companies set credible targets and implement practical measures, including energy efficiency improvements and renewable energy procurement. For businesses facing sustainability reporting requirements or supply chain scrutiny, compliance support ensures that carbon data meets regulatory and customer standards.
