Science Based Targets initiative (SBTi)
What Is the Science Based Targets initiative (SBTi)?
The Science Based Targets initiative (SBTi) is a global body that validates corporate climate targets, ensuring they are aligned with the latest climate science needed to meet the goals of the Paris Agreement.
In recent years, thousands of corporations around the world have pledged to achieve "Net Zero" emissions. However, without a universal standard, many of these pledges were criticized as vague marketing exercises or "greenwashing." The Science Based Targets initiative (SBTi) was established to solve this problem by acting as the primary global referee for corporate climate action. It is a collaborative partnership between the Carbon Disclosure Project (CDP), the United Nations Global Compact, the World Resources Institute (WRI), and the World Wide Fund for Nature (WWF). The core mission of the SBTi is to provide companies with a clearly defined pathway for reducing their greenhouse gas (GHG) emissions. For a target to be "SBTi Validated," it must be mathematically consistent with what the latest climate science says is necessary to meet the goals of the Paris Agreement—specifically, limiting global warming to 1.5°C above pre-industrial levels. By providing this rigorous, third-party validation, the SBTi ensures that a company's climate goals are not just ambitious, but are grounded in physical reality and actual atmospheric requirements. Today, the SBTi is the most influential body in the world of corporate sustainability. Having an SBTi-validated target has become a "license to operate" for many large public companies, as they face increasing pressure from regulators, consumers, and large institutional investors. It transforms climate action from a series of voluntary gestures into a disciplined, measurable, and scientifically verifiable business strategy that can be tracked and audited just like financial performance.
Key Takeaways
- A partnership between CDP, the UN Global Compact, WRI, and WWF that provides independent validation.
- It defines and promotes best practices in emissions reductions and net-zero targets for the private sector.
- Companies submit their decarbonization plans to SBTi to prove their targets are scientifically sound.
- Targets are considered "science-based" if they align with limiting global warming to 1.5°C above pre-industrial levels.
- SBTi approval is considered the global "gold standard" for corporate sustainability and climate claims.
- Investors use SBTi validation as a critical tool to screen companies for greenwashing risks and transition readiness.
How the SBTi Validation Process Works
The process for a company to have its targets validated by the SBTi is rigorous and multi-staged, designed to ensure that the plans are both comprehensive and actionable. It typically follows a five-step pathway. First, the company must "Commit," which involves sending a formal letter of intent to the SBTi. Second, the company must "Develop" its targets. This is the most technical phase, where the company must measure its current carbon footprint across Scope 1 (direct emissions), Scope 2 (purchased energy), and Scope 3 (the entire supply chain). Once the targets are developed, the company must "Submit" them for a detailed technical review. During this phase, SBTi's team of experts scrutinizes the data, the methodology, and the timelines to ensure they meet the strict 1.5°C criteria. If the targets pass, the fourth step is to "Communicate," where the company publicly announces its validated goals. Finally, the company enters the "Disclose" phase, which requires them to report their emissions and progress toward their targets every single year. A key differentiator of the SBTi is its strict stance on carbon offsets. Under the SBTi "Net-Zero Standard," companies cannot simply buy their way to Net Zero by purchasing cheap, unverified carbon credits from forest projects. Instead, they are required to achieve deep decarbonization—typically a 90% absolute reduction in emissions—before they can use high-quality carbon removal to "neutralize" the final, unavoidable 10% of their footprint. This focus on "actual" reductions rather than "offsetting" ensures that the SBTi remains the most credible standard for corporate climate leadership in the world.
Important Considerations for Investors and Companies
For investors, the SBTi has become a critical tool for "transition risk" analysis. A company with a validated science-based target is demonstrating that it has a plan to survive and thrive in a low-carbon economy. Conversely, a company in a high-emitting sector (like aviation or steel) that refuses to set an SBTi target is a red flag, signaling that management may be unprepared for future carbon taxes, stricter regulations, or shifting consumer preferences. For ESG (Environmental, Social, and Governance) funds, SBTi validation is often used as a mandatory filter for inclusion in their portfolios. For the companies themselves, the biggest consideration is the challenge of Scope 3 emissions. While a company can control the electricity it buys (Scope 2), it is much harder to control the emissions of thousands of small suppliers or the way customers use its products (Scope 3). However, because the SBTi requires Scope 3 targets for most large companies, it creates a "domino effect" throughout the global economy. When a giant like Apple or Walmart sets an SBTi target, it forces their entire global supply chain to decarbonize as well, effectively exporting high sustainability standards to every corner of the world. Finally, it is important to note the reputational risk of "de-listing." If a company commits to the SBTi but fails to submit its targets for validation within 24 months, the SBTi publicly marks their commitment as "Removed." This can lead to significant negative press and a loss of credibility with investors. This "name and shame" mechanism ensures that companies don't just use the SBTi for a quick PR boost, but are genuinely committed to the long-term work of transformation.

FAQs
No, it is currently voluntary. However, it is rapidly becoming "market-mandatory." Large institutional investors like BlackRock often demand SBTi-validated targets as a condition for investment. Furthermore, many large corporations now require their suppliers to have SBTi validation as a prerequisite for doing business. This commercial pressure is effectively forcing thousands of companies to join the initiative, regardless of whether it is a legal requirement in their specific country.
The 1.5°C target refers to the goal of the Paris Agreement to limit the global average temperature increase to no more than 1.5 degrees Celsius above pre-industrial levels. This is the threshold that scientists believe is necessary to avoid the most catastrophic and irreversible effects of climate change. The SBTi uses this specific temperature goal as the benchmark for its validation, ensuring that corporate action is sufficient to meet this global objective.
Generally, no. For "Near-Term" targets, the SBTi does not allow carbon offsets to count toward emissions reductions. The initiative insists that companies must find ways to actually eliminate emissions from their operations and supply chains. Offsets are only allowed in the "Long-Term" Net-Zero stage to neutralize the final, residual 10% of emissions that are technically impossible to eliminate. This prevents companies from avoiding the hard work of transformation by simply buying cheap, unverified carbon credits.
The SBTi aims to cover all sectors, but some are more complex than others. They have specific methodologies for sectors like power generation, cement, and aviation. For the fossil fuel (Oil and Gas) sector, the SBTi recently paused validations while it develops a more rigorous methodology that addresses the unique challenge of "Scope 3" emissions from the actual burning of oil and gas by consumers. This pause reflects the initiative's commitment to scientific integrity over simple participation.
Currently, the primary penalty is reputational. The SBTi does not have the power to levy fines. However, if a company fails to meet its targets, it may be removed from the SBTi's public database of validated companies. This can lead to a significant loss of investor confidence, a drop in ESG ratings, and potential legal challenges from shareholders who may claim the company made misleading statements about its climate progress.
The Bottom Line
The Science Based Targets initiative has fundamentally transformed corporate sustainability from a vague marketing exercise into a rigorous, data-driven scientific discipline. By tethering corporate climate goals to the hard math of the Paris Agreement, the SBTi provides a universal language for decarbonization that investors, regulators, and consumers can finally trust. For companies, an SBTi-validated target is a powerful signal of operational efficiency and long-term resilience in a low-carbon world. For investors, it is a critical filter for identifying transition risk and avoiding greenwashing. As the global economy moves toward Net Zero, the SBTi remains the definitive "gold standard" for climate accountability, ensuring that the corporate sector—the world's largest engine of emissions—is moving in a direction compatible with a livable and prosperous future for all.
