Schott Updates Climate Targets with New Science-Based Goals

German manufacturer abandons offset-based climate claims

Schott has withdrawn its climate-neutral production target and replaced it with science-based emissions reduction goals. The German specialty glass manufacturer announced the change in early 2026, moving away from a strategy that relied partly on carbon offsetting toward one focused on direct cuts across operations and supply chains.

The company now works to validated targets covering Scopes 1, 2 and 3 emissions. These targets have been approved by the Science Based Targets initiative (SBTi), an organization that assesses whether corporate climate plans align with limiting global warming to 1.5°C. For many UK businesses watching corporate climate strategies evolve, this shift illustrates a broader pattern in how large manufacturers are rethinking their net-zero approach.

Climate-neutral claims have come under growing scrutiny. Regulators, investors and customers increasingly question whether buying carbon credits from external projects constitutes genuine decarbonization. Consequently, businesses across Europe are revising their climate messaging to emphasize measurable reductions in their own emissions rather than compensation schemes. Schott's announcement reflects this trend and signals what industrial suppliers may soon face in procurement standards.

Original climate goals relied on offsetting

Schott had previously committed to climate-neutral production by 2030. That goal allowed the company to use carbon offsets and credits as part of its strategy. This approach was common among energy-intensive manufacturers seeking to demonstrate climate action without fully transforming production processes.

However, the company began shifting its framework in 2023. During that year, SBTi validated Schott's initial science-based targets. These included a 46.2% reduction in absolute Scope 1 and 2 greenhouse gas emissions by fiscal 2030, measured against a 2019 baseline. The targets also covered selected Scope 3 emissions, with a 27.5% reduction goal for categories including fuel, energy-related activities and investments.

The 2023 validation marked a turning point. Schott maintained both its internal climate-neutral goal and the new SBTi targets simultaneously. This dual approach created potential confusion about which commitments would drive actual investment decisions and operational changes. The company has now resolved that ambiguity by formally retiring the climate-neutral claim.

In its updated announcement, Schott stated that carbon credits from projects outside its own value chain are not part of the validated targets. This clarification matters because it removes the option to meet goals through external compensation. Instead, the company must reduce emissions directly through process changes, energy efficiency, renewable electricity and supply chain engagement.

Revised targets cover broader Scope 3 emissions

The updated framework expands Schott's Scope 3 coverage beyond the initial validation. Previously, the company focused on supplier engagement as a mechanism for addressing value chain emissions. The new targets specify absolute reductions across multiple Scope 3 categories, including purchased goods and services, fuel and energy-related activities, and processing of sold products.

Scope 3 emissions are those generated in a company's value chain but not under its direct operational control. For manufacturers, these typically represent the largest portion of total carbon footprint. Schott reported Scope 3 emissions of approximately 1.3 million tons of CO2 equivalent in 2019, providing a baseline for measuring progress.

The shift to absolute reduction targets changes the compliance burden. Rather than simply encouraging suppliers to set their own goals, Schott must now demonstrate actual decreases in value chain emissions. This requires deeper engagement with raw material providers, logistics partners and customers. It also creates ripple effects down the supply chain, as Schott will likely increase pressure on suppliers to provide verified emissions data and reduction plans.

UK businesses supplying into European manufacturing chains should note this development. Companies that serve as Scope 3 emission sources for larger manufacturers will face growing requests for carbon data, reduction commitments and verification evidence. This expectation is becoming standard in procurement, particularly for energy-intensive sectors such as glass, steel, cement and chemicals.

Glass production presents decarbonization challenges

Glass manufacturing is inherently energy-intensive. Melting raw materials requires sustained high temperatures, typically between 1,400°C and 1,600°C. Historically, this process has relied on fossil fuels, making Scope 1 emissions substantial. Reducing these emissions requires either switching to renewable energy sources such as green hydrogen or electric melting, or deploying carbon capture technology.

Schott has stated that its Scope 1 and 2 progress has already surpassed the previously validated target path. This suggests the company has made faster-than-expected gains, likely through a combination of energy efficiency improvements and increased renewable electricity procurement. Nevertheless, eliminating all emissions from high-temperature processes remains technically challenging and expensive.

The company's decision to drop offsetting may therefore reflect a pragmatic assessment. Rather than promising climate neutrality that depends on purchasing credits of uncertain quality, Schott is committing to reductions it can measure and verify. This approach reduces reputational risk and aligns with tightening standards around green claims.

UK SMEs in manufacturing should consider the implications. As larger companies in your supply chain adopt science-based targets, they will pass compliance expectations down to smaller suppliers. You may be asked to report emissions, set reduction goals or demonstrate alignment with SBTi methodology. Preparing for these requests now can prevent disruption to commercial relationships later.

What UK businesses need to understand

Schott has withdrawn its climate-neutral production goal and replaced it with SBTi-validated targets requiring a 46.2% reduction in Scope 1 and 2 emissions by fiscal 2030 from a 2019 baseline.
The company now commits to a 27.5% reduction in selected Scope 3 emissions, covering purchased goods and services, fuel and energy-related activities, and processing of sold products.
Carbon credits from projects outside Schott's own value chain are not part of the validated targets, meaning reductions must come from direct operational and supply chain changes.
Schott reported that its Scope 1 and 2 progress has already exceeded the previously validated target path, indicating faster-than-expected decarbonization.
The shift reflects broader corporate movement away from offset-reliant climate claims and toward measurable emissions reductions aligned with science-based methodologies.

Commercial implications for smaller suppliers

This development matters for UK SMEs in several ways. First, it signals how procurement standards are evolving across European manufacturing. Companies like Schott will increasingly require suppliers to provide verified emissions data as part of tendering and contract renewal processes. If you supply materials, components or services to manufacturers with science-based targets, expect requests for Scope 1, 2 and 3 emissions reporting.

Second, the move away from offsetting changes the nature of climate commitments. Buyers will scrutinize whether your reduction plans involve actual operational changes or rely on purchasing credits. This distinction affects how your sustainability credentials are perceived in competitive tenders. Demonstrating genuine emissions reductions through energy efficiency, renewable electricity or process improvements will carry more weight than offset purchases.

Third, Scope 3 targets create cascading obligations. When a large manufacturer commits to reducing value chain emissions, it must engage suppliers and customers to achieve those goals. For smaller businesses, this means increased scrutiny of your carbon footprint and potentially mandatory participation in supplier decarbonization programs. You may be asked to set your own science-based targets or align with your customer's reduction pathway.

Furthermore, regulatory trends reinforce this shift. The UK government has introduced carbon reporting requirements for large companies and is expanding environmental disclosure standards. Meanwhile, the EU Corporate Sustainability Reporting Directive requires detailed Scope 3 reporting from companies operating in European markets. These regulations make verified emissions data a compliance necessity, not just a voluntary disclosure.

Businesses serving public sector clients face additional pressure. Procurement Policy Note 06/21 requires suppliers bidding for major government contracts to publish a carbon reduction plan and commit to net zero by 2050. As central government and local authorities tighten implementation, demonstrating credible emissions reductions becomes essential for maintaining public sector revenue streams. Our net-zero program for carbon reporting compliance helps businesses meet these requirements.

Building a credible reduction strategy

If you anticipate similar requests from your own customers, start by measuring your baseline emissions. You cannot manage what you do not measure. Calculate your Scope 1 and 2 emissions first, as these are under your direct control and typically easier to verify. Scope 1 covers direct emissions from owned or controlled sources such as company vehicles and on-site fuel combustion. Scope 2 covers indirect emissions from purchased electricity, heat or steam.

Once you have a baseline, identify reduction opportunities. Common starting points include switching to renewable electricity tariffs, improving building insulation, upgrading heating systems and optimizing logistics. Many of these measures also reduce operating costs, creating a dual commercial benefit. However, avoid overstating the carbon impact of minor changes or relying on offsetting as a primary strategy.

Scope 3 is more complex. These emissions occur across your value chain, including purchased goods, transportation, waste disposal and use of sold products. Calculating Scope 3 requires data from suppliers and customers, which smaller businesses often struggle to obtain. Nevertheless, if your customers set value chain reduction targets, they will expect you to engage with this process. Building supplier relationships that include emissions data sharing will become increasingly important.

Consider whether science-based targets are appropriate for your business. SBTi offers a framework for small and medium enterprises, with simplified methodologies for companies with fewer than 500 employees. Setting a validated target demonstrates commitment and aligns your strategy with emerging best practice. It also positions you as a preferred supplier for customers pursuing their own SBTi goals.

Training your team on carbon management and reporting standards can accelerate progress. Understanding how to collect emissions data, apply calculation methodologies and verify reductions will become a core business skill. Resources such as the SBS Academy training on Scope 3 emissions provide practical guidance tailored to UK SMEs.

Regulatory and market context

The move by Schott reflects wider changes in how climate commitments are assessed. Regulators in multiple jurisdictions have begun scrutinizing green claims more closely, concerned that vague or misleading statements distort markets and undermine genuine climate action. The UK Competition and Markets Authority published guidance in September 2021 warning businesses against making environmental claims they cannot substantiate.

In the EU, the Green Claims Directive proposes to ban unsubstantiated climate-neutral claims and require rigorous verification of environmental statements. While the UK is not bound by EU legislation, UK businesses exporting to Europe must comply with these standards when marketing to EU customers. Additionally, UK regulators often adopt similar approaches to their European counterparts, meaning stricter domestic rules may follow.

Financial markets are also driving change. Investors increasingly use environmental, social and governance (ESG) criteria to assess risk and allocate capital. Companies with credible, science-based reduction targets are viewed as lower risk than those relying on offsetting or making unsupported claims. This dynamic affects access to finance, insurance costs and shareholder expectations.

For listed companies and large corporates, these pressures are already material. However, smaller businesses feel the impact indirectly through supply chain requirements, tender criteria and customer expectations. As sustainability reporting becomes embedded in commercial relationships, SMEs that prepare early will have a competitive advantage over those that wait until compliance is mandatory.

The UK government's net zero strategy sets out how the country will reach net zero emissions by 2050. This strategy includes sector-specific pathways for industry, transport, buildings and energy. Understanding where your business sits within these pathways can help you anticipate future regulatory requirements and market shifts.
