Net zero has become one of the most contested ideas in business and politics. Yet while the debate over how fast, how far and who pays becomes louder, the underlying science hasn’t changed: limiting the worst impacts of climate change means cutting global emissions deeply and quickly. Whether a business is driven by customer expectations, procurement requirements, investor scrutiny or its own exposure to climate risk, the destination is the same. A target is only the starting point. Its real value lies in the decisions that follow.
What does net zero mean in simple terms?
In a corporate context, net zero means reducing greenhouse gas emissions across the business and its value chain by at least 90%, then permanently neutralising the residual emissions that cannot yet be eliminated.1
Net zero should not be confused with carbon neutrality. Carbon neutrality can be achieved through the purchase of carbon credits whereas a credible net zero strategy prioritises deep and sustained emissions reductions within the organisation’s own operations and value chain. Certified removals have a role, but they cannot substitute for action on the sources of emissions that a business can influence. To reflect this, PAS 2060, which had been the recognised specification for carbon neutrality, has been withdrawn and ISO 14068:2026 was published in September 2026, essentially replacing it. This ISO standard is more net zero-aligned than PAS 2060, prioritising science-aligned decarbonisation before allowing for offsetting residual emissions.
Why is net zero important for businesses?
Setting a clear net zero target gives the organisation a shared direction for decision-making. It creates a common reference point for leadership, finance, procurement and operational teams, helping them assess whether investment, supplier choices and business priorities support the company’s long-term ambitions. A target also makes progress easier to measure and communicate, giving customers, employees and investors greater confidence that climate considerations are being managed with purpose and accountability.
The business case begins with resilience. Climate-related disruption can affect asset availability, energy costs, logistics, insurance and access to critical materials. A severe weather event or interruption to a key transport route can quickly become a customer, revenue and margin issue.
A robust transition plan helps leadership teams understand these exposures alongside the organisation’s emissions profile. Transition planning turns a net zero commitment into a practical, achievable business plan, with net zero as the north star 2. It turns ambition into accountable action, helping to “catalyse action, operationalise commitments, and demonstrate credibility”.3 It also brings climate decisions into mainstream business planning: which assets require investment, where supplier engagement is most needed, which measures can reduce costs now and which dependencies create longer-term risk.
Regulation, procurement expectations and evolving good practice are also important drivers of decarbonisation. For relevant UK central government contracts valued above £5 million per year, PPN 006 requires bidding suppliers to provide a Carbon Reduction Plan. This requires reliable emissions data, senior approval and a published plan.
The Transition Plan Taskforce Disclosure Framework, which IFRS S2 builds upon, sets out good practice for robust and credible transition plan disclosures. For finance teams, these developments bring climate planning closer to capital allocation, governance and risk management, all of which are central to successful decarbonisation.4 From February 2027, the SBTi’s Corporate Net Zero Standard V2.0 will strengthen this expectation further. Companies seeking validation will be required to develop and maintain a transition plan demonstrating how they will implement their science-based targets.5
Clients and investors are asking sharper questions. Can the business evidence its emissions baseline? Are targets feasible? What capital is required? Who owns delivery? What happens if a key assumption changes? Clear answers protect customer relationships and build confidence with lenders, investors and boards.
For me, net zero becomes much more meaningful when it starts shaping decisions the business is already making. It doesn’t necessarily mean creating a completely separate programme or relying on a target to do the work on its own. The opportunity is to understand where emissions, climate risk and commercial priorities intersect, then connect that with the way the organisation invests, buys, operates and works with suppliers.

What are examples of net zero action that drive value?
Net zero action delivers most value when it is linked to business priorities. Renewable electricity procurement, energy efficiency and fleet improvements can reduce operating costs and exposure to energy price volatility. Better logistics planning can cut fuel use and improve service reliability. Supplier engagement can uncover opportunities for product innovation, collaboration and more resilient sourcing.
The challenge is prioritisation. Not every initiative should happen at once, and the lowest cost action is likely not to be the most strategically valuable. Leadership teams need to weigh emissions impact against capital requirements, payback periods, operational feasibility and the risk of delay. For example, an energy efficiency programme may offer immediate savings, whereas a supplier engagement programme could be critical to reducing a much more significant share of Scope 3 emissions and protecting a major customer relationship.
Strong transition planning identifies the most material emissions sources, assesses the financial and operational implications of available levers, sets milestones and assigns accountable owners. Progress is then measured against a credible baseline, reviewed by leadership and communicated transparently.
This approach builds trust. Employees are increasingly sceptical that their employers are taking sufficient action to combat climate change.6 Customers want evidence behind sustainability claims.7 Investors want assurance that climate commitments are supported by governance and delivery plans. A strategy grounded in real operational change is more persuasive than broad promises.
Most importantly, transition planning helps leaders anticipate change rather than be reactive to it. It creates the discipline to test business models, direct investment and build advantage as markets, technology and stakeholder expectations evolve.
