The Science Based Targets initiative (SBTi) has released Version 2.0 of its Corporate Net-Zero Standard, introducing the most significant update to corporate net-zero target setting since the original framework was launched in 2021.
The original standard has helped thousands of organisations set science-based targets. However, experience has shown that setting ambitious goals is only part of the challenge. Delivering meaningful emissions reductions, particularly across complex supply chains can be much harder.
The updated standard reflects these practical realities while maintaining alignment with climate science. More importantly, it signals a shift towards helping businesses demonstrate how they are turning net-zero commitments into measurable action.
One of the biggest changes in Version 2.0 is its emphasis on implementation rather than ambition alone.
Businesses are increasingly expected to show how climate targets influence decisions across the organisation, from procurement and investment to governance and long-term business strategy.
The updated standard encourages companies to:
For many organisations, this reflects the growing expectations of investors, customers and regulators for credible, evidence-based climate action.
A key feature of the updated standard is the introduction of a best efforts approach, particularly for emissions that businesses do not directly control.
Rather than expecting organisations to achieve fixed outcomes regardless of changing circumstances, the SBTi recognises that some factors, particularly within complex global value chains are outside a company's direct influence.
Businesses are expected to use every reasonable opportunity to reduce emissions while demonstrating:
The aim is to balance ambition with practicality, while ensuring companies remain accountable for meaningful climate action.
Scope 3 emissions remain one of the biggest challenges for organisations pursuing net zero. These indirect emissions, generated throughout the value chain, often account for the majority of a company's carbon footprint.
The updated standard recognises that organisations have varying levels of influence over these emissions and introduces greater flexibility in how businesses can demonstrate progress.
This includes a stronger focus on:
While businesses are still expected to address Scope 3 emissions, the revised framework acknowledges that achieving reductions often depends on collaboration across the wider value chain.
The updated standard also provides clearer guidance on the role of carbon removals in achieving net zero.
The SBTi continues to stress that reducing emissions must remain the priority. However, it also recognises that some residual emissions may remain after all reasonable reduction opportunities have been exhausted.
The updated guidance provides more clarity on:
Businesses with existing science-based targets do not need to make immediate changes. Validation under Version 2.0 is expected to begin in February 2027, giving organisations time to understand the updated requirements and assess how they may affect existing climate strategies.
In the meantime, organisations should consider:
The direction of travel is becoming increasingly clear. Setting a net-zero target is no longer the finish line, it is the starting point.
Organisations are expected to demonstrate how climate commitments are influencing business decisions, how progress is being measured, and how emissions reductions are being achieved in practice.
For businesses already on their decarbonisation journey, the updated SBTi Corporate Net-Zero Standard provides an opportunity to strengthen existing plans, engage more effectively with suppliers and stakeholders, and build confidence that net-zero commitments are supported by credible, measurable action.
The updated SBTi standard raises the bar for businesses looking to set and achieve credible net-zero targets. Whether you're just getting started or reviewing your existing strategy, having the right support can make the process much more manageable.
At Climate Essentials, we work with organisations to understand their carbon footprint, identify practical opportunities to reduce emissions, and develop net-zero strategies that are realistic, evidence-based and aligned with the SBT frameworks.
If you're looking to understand what the updated standard means for your organisation, we'd be happy to help.
