Block Reports 593,915 Tonnes of CO₂e Emissions in 2025 as Sustainability Efforts Expand

Block’s 2025 Business Sustainability Report puts its total carbon footprint at 593,915 metric tonnes of CO₂e, with most emissions coming from the company’s broader value chain.

Block is putting a sharper focus on the environmental impact of its fintech ecosystem as it releases its 2025 Business Sustainability Report, outlining how the company measures emissions and manages sustainability across its operations, products, and partnerships.

The report shows that Block’s total carbon emissions reached 593,915 metric tonnes of carbon dioxide equivalent (CO₂e) in 2025.

The majority of that footprint came from the company’s broader value chain, including products and services purchased from suppliers and vendors.

That distinction matters for a financial technology company with a large ecosystem of hardware, payment processing, cloud infrastructure, suppliers, and other external partners.

Rather than treating sustainability as an issue limited to its own offices and direct operations, Block is increasingly looking at the emissions generated across the wider business model.

Block 2025 Business Sustainability Report Highlights Value-Chain Emissions

Block’s latest report shows why Scope 3 emissions remain one of the harder challenges for large technology and fintech companies.

These emissions occur throughout the value chain rather than directly from facilities or company-owned operations. For Block, that can include areas such as purchased goods and services, hardware, logistics, cloud infrastructure, and payment-related activities.

Block has previously reported that Scope 3 emissions represented the overwhelming majority of its overall carbon footprint. Its 2024 sustainability disclosures, for example, showed Scope 3 accounting for 98.92% of total emissions.

That makes supplier engagement particularly important.

A fintech company can reduce energy consumption in its own offices, but the bigger challenge can sit further upstream—in manufacturing, transportation, hardware production, and the technology infrastructure that supports its products.

Block says it continues to track this broader footprint while working on ways to reduce environmental impact across its ecosystem.

Carbon Removal Remains Part of Block’s Climate Strategy

Block is also continuing to invest in carbon removal as part of its climate strategy.

The company’s 2025 climate disclosure says it purchased 150,000 tonnes of high-quality carbon removal credits during the year. Block is working toward its goal of achieving net-zero carbon emissions from operations by 2030.

Carbon removal is only one part of that strategy.

Block says it is also investing in renewable energy and working to develop more sustainable approaches across areas such as hardware, packaging, and shipping.

That combination is important because purchasing carbon-removal credits does not eliminate the underlying emissions generated by a business.

The longer-term challenge is to reduce those emissions at the source while using carbon removal as part of the transition.

For Block, that means looking beyond corporate offices and directly into the physical and digital infrastructure supporting its products.

Oceanworks Partnership Recovers 2 Million Pounds of Plastic

Block’s sustainability strategy also extends beyond carbon emissions.

Through its partnership with Oceanworks, the company says it helped reclaim 2 million pounds of at-risk plastic waste from waterways and coastal areas in 2025.

That brought the total amount of plastic recovered through the partnership to 6.3 million pounds since the relationship began.

The initiative builds on Block’s previous work to address plastic waste linked to its broader business ecosystem.

Block first partnered with Oceanworks in 2022, when it funded the removal of 1 million pounds of ocean-bound at-risk plastics. Its earlier sustainability reporting described projects spanning fishing-net collection, waterway plastic recovery, and recycling initiatives.

The latest figure suggests that the partnership has become a longer-term component of Block’s sustainability program rather than a one-off environmental initiative.

Hardware and Supply Chains Are Key Sustainability Challenges

For a company operating across fintech, commerce, and consumer payments, hardware presents a particularly important sustainability challenge.

Physical products create emissions across manufacturing, transportation, packaging, and eventual disposal.

Block, therefore, says it is exploring more sustainable approaches to hardware, packaging, and shipping.

The company’s earlier carbon disclosures also identified hardware as one of the significant contributors to its Scope 3 footprint. In 2024, hardware accounted for more than 16% of Block’s reported emissions.

That puts product design and supplier relationships at the center of Block’s environmental strategy.

Reducing material use, increasing recycled content, improving product durability, and making logistics more efficient can potentially reduce emissions before products even reach customers.

Why Block’s Sustainability Strategy Matters for Fintech

The sustainability debate in fintech is becoming more complicated.

Digital payments may appear lighter than traditional financial infrastructure because they reduce dependence on cash, paper, and physical branches. However, the underlying technology ecosystem still requires data centers, payment networks, cloud computing, hardware, logistics, and global supply chains.

That creates a carbon footprint that is easy to overlook.

Block’s latest report highlights this reality.

The company’s environmental impact does not sit in one place. It is spread across the ecosystem that enables merchants to accept payments, consumers to use financial products, and businesses to operate through Block’s platforms.

Consequently, managing that impact requires more than purchasing renewable energy or offsetting corporate emissions.

It requires working with suppliers, redesigning products, improving logistics, and measuring emissions throughout the value chain.

The Bigger Picture: Sustainability Is Becoming an Operating Issue

Block’s latest report also reflects a broader shift in corporate sustainability.

Companies are increasingly moving away from treating ESG reporting as a standalone disclosure exercise. Instead, environmental performance is becoming part of decisions around procurement, product development, logistics, and partnerships.

For fintech companies, that shift could become particularly important as their physical and digital infrastructure expands.

Block’s 593,915-tonne footprint shows the scale of the challenge.

At the same time, the company’s investments in carbon removal, renewable energy, hardware, packaging, and plastic recovery show how it is attempting to address different parts of that footprint.

The key test will be whether those initiatives can reduce the underlying emissions intensity of the business as Block continues to grow.

For now, the 2025 Business Sustainability Report provides a clearer picture of where the environmental pressure sits: largely outside Block’s direct operations and across the wider value chain.

That makes suppliers, products, and partnerships just as important to the company’s climate strategy as its own offices and operations.
