Net Zero Trajectory & Science-Based Targets
Target Lock
Setting a net zero target without a validated trajectory is a press release, not a strategy. Science-based targets give your decarbonization plan a destination, a timeline, and the credibility to back up the claim.
Key Takeaways
- Science-based targets (SBTs) are emission reduction goals aligned with what climate science says is needed to limit warming to 1.5°C.
- The Science Based Targets initiative (SBTi) validates corporate targets against peer-reviewed methodologies.
- Over 7,000 companies worldwide have committed to SBTi; validated targets are increasingly a procurement and financing prerequisite.
- A net zero trajectory covers near-term targets (5-10 years) and long-term goals (2050), with interim milestones.
- Bleen builds your trajectory from carbon assessment to SBTi submission in 6 to 12 weeks.
What Are Science-Based Targets and Net Zero Trajectories?
Science-based targets are greenhouse gas emission reduction goals that align with the pace and scale of reductions needed to limit global warming to 1.5°C above pre-industrial levels, as outlined in the Paris Agreement. They are not arbitrary percentages chosen by a sustainability team. They are calculated using sector-specific methodologies and validated by the Science Based Targets initiative (SBTi).
A net zero trajectory is the pathway from your current emissions to net zero, defined as the state where residual emissions are balanced by verified removals. The SBTi Net-Zero Standard requires companies to reduce emissions by at least 90% before relying on any removal or offset mechanism. This is not a distant aspiration. It is a structured plan with near-term targets (typically 5 to 10 years) and long-term commitments (2050 or sooner).
The two concepts work together. Science-based targets set the pace. The net zero trajectory maps the route. Without SBTs, a net zero pledge has no verifiable methodology behind it.
Why Set Science-Based Targets?
Credibility is the first reason. Over 7,000 companies globally have committed to SBTi. Validated targets are becoming a baseline expectation in investor due diligence, not a differentiator. Companies without them face growing questions about the seriousness of their climate commitments.
The EU Green Claims Directive will require evidence-based environmental assertions. A net zero claim backed by validated SBTs meets that bar. A net zero claim backed by nothing invites regulatory scrutiny.
Financial access is the second driver. Green bonds, sustainability-linked loans, and ESG-screened funds increasingly require validated decarbonization targets. Banks and asset managers use SBTi status as a screening criterion. No targets, no access to the cheapest capital.
Supply chain pressure is the third. Large companies with validated SBTs need their suppliers to set targets too (scope 3 alignment). This is cascading down value chains. Companies that set targets early position themselves as preferred suppliers.
How Bleen Builds Your Net Zero Trajectory
We work from your carbon footprint assessment (or conduct one if needed) and build the trajectory in four stages.
Stage 1: Baseline and boundary setting. We confirm your emissions baseline, verify scope coverage, and define the boundary for target setting. SBTi requires scope 1, 2, and relevant scope 3 categories. We identify which scope 3 categories are material and need inclusion.
Stage 2: Target calculation. We apply SBTi-approved methodologies (absolute contraction, sectoral decarbonization, or physical intensity) to calculate your near-term and long-term targets. We model different scenarios: what happens at different ambition levels, with different technology assumptions, and different investment timelines.
Stage 3: Trajectory roadmap. We translate targets into a year-by-year emissions reduction pathway with specific actions, milestones, and investment requirements. The roadmap covers energy efficiency, renewable energy procurement, supplier engagement, product redesign, and residual emission management.
Stage 4: Submission and validation. We prepare your SBTi submission package: target documentation, methodology justification, and supporting data. We manage the review process and handle any clarification requests from SBTi.
Official validation timelines run 30 business days for near-term targets and 60 for net-zero targets — provided the submission is complete and accurate on first attempt. In practice, incomplete submissions can extend the process considerably. Our role is to get it right the first time.
Who Needs Science-Based Targets?
Companies that have made net zero pledges and need a validated methodology behind them. Pledges without SBTs are increasingly flagged as greenwashing by NGOs, media, and regulators.
Businesses facing investor pressure on climate. If your largest shareholders or lenders are PRI signatories or Climate Action 100+ members, they expect science-based targets.
Suppliers of companies with validated SBTs. Scope 3 alignment means your clients need you to set targets. This is not optional if you want to remain in their supply chain.
Companies targeting green finance instruments. SBTi validation is a gating criterion for many sustainability-linked bonds and loans.
How Bleen Supports Your SBTi Journey
We have guided companies through the full SBTi process: from baseline assessment to validated targets. We know the methodology requirements, the common rejection reasons, and how to avoid them.
Our approach is practical. We do not build targets your organization cannot deliver. We model realistic scenarios based on your sector, your investment capacity, and your operational constraints. Ambitious but achievable.
Typical engagement: 6 to 12 weeks from baseline to submission-ready package. Deliverables include the emissions baseline, target calculations, trajectory roadmap, and complete SBTi submission documentation.
