Climate Strategy Guide for Companies

Last updated: May 17, 2026.

A strong climate strategy is not just a net-zero sentence in a sustainability report. It is a practical plan for how the company will understand climate-related risks, measure emissions, reduce value-chain impacts, respond to customer and investor expectations, and keep the business resilient as policy, technology, markets, and physical climate risks change.

The strongest climate strategies connect three things: the company's emissions baseline, the climate risks and opportunities that affect the business, and the actions the company can actually fund, govern, and deliver. Without that connection, climate strategy becomes either a communications exercise or a long list of projects with no commercial logic.

This guide explains how to build a climate strategy that can support board decisions, customer responses, sustainability reporting, supplier engagement, and credible progress over time. Keslio can help with sustainability strategy, GHG emissions calculations, reporting and communications, and supplier request support.

Short answer: A strong climate strategy starts with a GHG inventory, identifies material climate risks and opportunities, sets realistic targets, defines reduction actions, assigns governance and budgets, tracks progress, and communicates with evidence. Companies should avoid setting public targets before they understand their emissions baseline, Scope 3 exposure, operational levers, supplier dependencies, and reporting obligations.

Why climate strategy matters

Climate strategy matters because climate change affects both the company and the stakeholders around it. Customers may ask for emissions data. Investors and lenders may ask how climate risks affect financial performance. Regulators may require climate disclosure. Employees may want evidence that the company is serious. Suppliers may need guidance on data and decarbonization expectations.

The work is also becoming more connected. Climate reporting under TCFD-style structures, ISSB/IFRS S2, ESRS E1, customer questionnaires, and voluntary net-zero frameworks all ask versions of the same questions:

Who governs climate-related risks and opportunities?
What emissions does the company produce across Scope 1, Scope 2, and relevant Scope 3 categories?
Which climate risks and opportunities affect the business model, value chain, and financial planning?
What targets has the company set, and are they supported by actions?
How will the company track and report progress over time?

A climate strategy gives the company one coherent answer instead of a new scramble for every report, RFP, board deck, or supplier portal.

Start with the emissions baseline

A climate strategy needs a baseline. Most companies should start with a greenhouse gas inventory covering Scope 1 and Scope 2 emissions, then screen relevant Scope 3 categories. The GHG Protocol remains the main reference point for corporate emissions accounting, and its standards divide emissions into direct emissions, purchased energy emissions, and value-chain emissions.

The baseline should document:

The reporting period.
The organizational boundary and consolidation approach.
The sites, entities, activities, and geographies included.
Scope 1 emission sources, such as fuel combustion, fleet, refrigerants, and process emissions.
Scope 2 purchased electricity, steam, heat, or cooling.
Relevant Scope 3 categories, such as purchased goods and services, logistics, business travel, employee commuting, use of sold products, waste, or investments.
Activity data, emission factors, assumptions, exclusions, and data gaps.

For a primer, see Keslio's guide to Scope 1, Scope 2, and Scope 3 emissions. If your data is messy, see how to improve emissions data accounting.

Identify climate risks and opportunities

Emissions are only one part of climate strategy. Companies also need to understand how climate-related risks and opportunities affect operations, strategy, supply chains, costs, revenue, assets, customer relationships, and access to finance.

Common transition risks include carbon pricing, changing customer requirements, procurement rules, energy cost exposure, product standards, technology shifts, reputational pressure, and climate disclosure requirements. Common physical risks include heat, flooding, storms, drought, water stress, wildfire, supply disruption, and damage to sites or logistics routes.

Climate opportunities may include energy efficiency, renewable electricity, lower-emission products or services, more resilient suppliers, better data systems, access to green finance, and stronger customer retention where climate evidence matters in procurement.

A good climate strategy translates these issues into business language. For example, a customer emissions request is not only a reporting task; it can affect contract renewal. Energy efficiency is not only an environmental project; it can reduce operating cost and exposure to price volatility.

Use materiality to prioritize

Not every climate topic deserves the same level of effort. A materiality assessment helps the company decide which climate-related impacts, risks, and opportunities matter most for strategy and reporting.

For companies reporting under ESRS, climate may need to be assessed through double materiality. For investor-oriented disclosure, financial materiality and climate-related risks and opportunities are central. For GRI-style impact reporting, emissions and climate impacts may need to be explained as part of the company's broader impact profile.

Keslio's article on materiality assessment explains how to structure that process.

Set targets after the baseline

Targets are useful only when they are connected to a baseline and an implementation plan. Companies should avoid announcing a net-zero, carbon neutral, or emissions reduction target before they know what is included, which emissions sources dominate, and which reductions are feasible.

A target should define:

The baseline year and baseline emissions.
The emissions scopes and categories covered.
The target year and interim milestones.
Whether the target is absolute, intensity-based, supplier-engagement based, or activity-based.
The reduction actions expected to deliver the target.
How progress will be measured and updated.
What role, if any, carbon credits, removals, or beyond value chain mitigation will play.

Companies using science-based target frameworks should check the current SBTi criteria before submitting targets, because SBTi target-setting criteria and net-zero standards have been undergoing updates. The practical lesson is stable even as the details evolve: the target should be grounded in credible emissions accounting and value-chain reduction actions.

Build the transition plan

A climate target says where the company wants to go. A transition plan explains how it intends to get there.

A useful transition plan includes:

Governance and accountability.
Emissions baseline and material sources.
Priority reduction levers.
Capital and operating expenditure needs.
Supplier and customer engagement actions.
Policy, product, operational, or procurement changes.
Interim milestones and performance indicators.
Dependencies, assumptions, and risks.
Progress review and reporting process.

IFRS S2 and other climate disclosure frameworks have increased attention on transition plans, climate resilience, and the connection between climate strategy and financial planning. The plan does not need to be perfect in year one, but it should be specific enough to guide decisions.

Choose practical reduction levers

Climate strategies work when reduction actions are concrete. Common levers include:

Energy efficiency: improving equipment, building controls, lighting, heating, cooling, and process efficiency.
Renewable electricity: procurement of renewable electricity, power purchase agreements, onsite solar, or credible electricity instruments where appropriate.
Fleet and transport: route optimization, electrification, modal shifts, lower-emission logistics providers, and reduced business travel.
Product and service design: lower-emission materials, longer product life, circular design, lower-energy use, and service models that reduce waste.
Procurement and suppliers: supplier emissions data, supplier targets, low-carbon materials, traceability, and contract requirements.
Facilities and operations: refrigerant management, fuel switching, waste reduction, water efficiency, and process changes.
Data systems: better source data, evidence packs, annual refreshes, and controls over assumptions and emission factors.

For companies with large purchased goods, logistics, or outsourced services, supplier engagement is often central. Keslio's article on sustainable sourcing for companies explains how procurement teams can turn supplier sustainability into an evidence-led process.

Build supplier and customer workflows

Climate strategy increasingly lives in customer and supplier workflows. A customer may ask for Scope 1, Scope 2, Scope 3, renewable electricity, product-level data, service-level emissions, a methodology note, or a transition plan summary. A company may need similar information from its own suppliers.

Companies should create repeatable workflows for:

Receiving and interpreting customer climate requests.
Assigning internal owners for data and response drafting.
Collecting emissions and activity data from suppliers.
Reviewing supplier evidence and assumptions.
Preparing customer-ready methodology notes.
Refreshing data annually.

This is especially important for companies that sell to large enterprise customers. The commercial risk is not only climate regulation; it is losing time, credibility, or contracts because the company cannot respond to buyer requirements.

Assign governance and ownership

A climate strategy needs clear ownership. Without it, the sustainability team ends up chasing data from finance, procurement, operations, HR, and sales every reporting cycle.

Good governance defines:

Board or leadership oversight.
Management owner for climate strategy.
Data owners for emissions sources and supplier information.
Finance input on cost, savings, capex, and risk exposure.
Procurement responsibility for supplier data and sourcing decisions.
Legal or compliance review for higher-risk claims and disclosures.
Reporting cadence and escalation routes.

This governance structure should be proportionate to the company. A small business does not need a complex committee structure, but it still needs named owners and a repeatable process.

Report progress with evidence

Climate communication should be specific and evidence-backed. Reports and customer responses should explain what is included, what is excluded, which methodology was used, what changed from the previous year, and what the company is doing next.

For climate disclosure structure, see Keslio's practical guide to TCFD recommendations and ISSB climate disclosures. For claims discipline, see how to communicate sustainability efforts without greenwashing.

Common mistakes

Setting targets before calculating emissions: the target may look good but fail once real data arrives.
Ignoring Scope 3: value-chain emissions are often material and are frequently requested by customers.
Separating climate from finance: climate strategy should connect to cost, capex, risk, revenue, and contract exposure.
Making a strategy with no owners: a plan without data owners, budget owners, and decision owners will stall.
Relying on offsets too early: reductions inside the value chain should come first, with any credits or removals clearly explained.
Reporting only success stories: credible climate reporting also explains gaps, limitations, and methodology changes.
No annual refresh: emissions data, targets, supplier information, and customer requests need regular updates.

What to prepare before starting

Before building or refreshing a climate strategy, gather:

Entity, site, facility, and operational boundary information.
Energy, fuel, refrigerant, fleet, waste, logistics, travel, and procurement data.
Scope 1 and Scope 2 emissions calculations, if available.
Scope 3 screening or prior supplier data requests, if available.
Customer climate requests, supplier portals, RFPs, and contract requirements.
Risk registers, site exposure information, insurance issues, and climate-related incidents.
Existing climate targets, sustainability commitments, or net-zero statements.
Energy efficiency, renewable electricity, procurement, fleet, travel, and product initiatives already underway.
Prior sustainability reports, board materials, and investor or lender requests.
