Executive summary
A climate transition plan explains how the business expects to deliver its ambitions and respond to climate-related risks. It needs decisions, resources and responsibilities, with clear assumptions about suppliers, technology and customer demand. The Transition Plan Taskforce (TPT) framework provides a useful structure, while IFRS guidance explains relevant disclosures for entities applying IFRS S2.[1, 2] Neither should be presented as a universal duty for every contractor. Use the plan to expose delivery gaps and inform investment, rather than relying on a distant target alone.
Start here
Take your largest emissions source and identify the next funded decision needed to reduce it, who owns it and what could delay it.
In plain terms
A target describes the intended destination. A transition plan explains the business changes, resources and dependencies needed to get there, and how progress will be assessed. For construction, that can connect fleet replacement, site energy, product choices and supplier engagement with commercial planning and resilience to heat or flooding.[1, 2]
Five elements to connect
| TPT element | Construction planning question |
|---|---|
| Foundations | Which business activities, ambitions and assumptions does the plan cover? |
| Implementation strategy | Which operational changes and investments will deliver it? |
| Engagement strategy | What needs to change with suppliers, customers and other partners? |
| Metrics and targets | How will emissions, delivery milestones and dependencies be tracked? |
| Governance | Who decides, funds, challenges and updates the plan?[1] |
Distinguish the plan from the disclosure duty
IFRS S2 does not itself require an entity to have a transition plan. An entity applying it must disclose material information about climate-related risks and opportunities, including any transition plan it has and relevant assumptions and dependencies. The June 2025 guidance adds no new requirements.[2]
The UK government consulted in 2025 on potential transition-plan requirements. The consultation is a proposal, not a universal obligation to produce a plan.[3] Check the rules for the specific entity and any lender or customer condition. A procurement Carbon Reduction Plan may support the work but has a different purpose and scope.
Show what is funded and what depends on others
Recommended practice is to separate approved actions from options awaiting budget, infrastructure or technical decisions. Show gross emissions reductions separately from carbon credits, and explain residual gaps. Test the effect of business growth and supplier uncertainty. Include physical resilience where it affects delivery; a lower-emissions fleet still needs a workable depot and charging plan.[2]
Recommended actions
Suggested owners, timing and evidence for the next steps:
Agree the brief
Set the entity boundary, baseline, target, time horizons and reporting purpose. Keep a decision record linking the plan to the business strategy and any applicable disclosure requirements.
Board sponsor, before plan development
Build the action portfolio
Identify practical changes and dependencies for the largest emissions sources. Record expected effects, assumptions, delivery owners and technical questions rather than accepting unsupported savings estimates.
Operations and procurement, during options review
Connect costs and resources
Distinguish committed expenditure from proposals. Test affordability, implementation capacity and sensitivity to energy prices or demand. Keep an approved investment schedule and the decisions still required.
Finance, before investment approval
Agree external dependencies
Document the supplier, customer, infrastructure and skills changes needed. Assign engagement actions and contingency options, with evidence of agreements and a route for escalating obstacles.
Commercial and supplier leads, before commitments
Review delivery and revise
Compare actual emissions and milestones with the plan, investigate variances and update forecasts. Keep changes and approvals visible so external reporting reflects the current delivery position.
Board sponsor, each planning cycle
Example in practice
Illustrative example: a merchant plans to replace ten diesel vans with electric vehicles. Only four charging bays are funded. The plan records the vehicle decision, depot capacity, budget gap and interim operating assumptions. It reports the expected emissions effect as a forecast until vehicles and charging are operating.
Common mistakes
- Listing targets without actions: connect each priority to a funded decision and owner.
- Adding overlapping savings: reconcile measures against one baseline and model their interaction.
- Assuming supplier delivery: record dependencies and alternative actions.
How Reinventives can help
Reinventives can connect your footprint, action portfolio and reporting process through a responsibility map, evidence register and implementation plan. A first deliverable can identify gaps between current targets, funded actions and the data needed to monitor delivery. We coordinate specialist engineering, scenario analysis or assurance support where the assignment requires it.
