Businesses are under increasing pressure to reduce greenhouse gas emissions, improve sustainability performance, and turn net zero commitments into measurable action. Achieving these goals often requires more than setting targets. Organisations may need support with emissions measurement, decarbonization planning, sustainability reporting, technology, data management, and operational transformation.
Net zero consulting companies help businesses navigate these challenges by developing climate strategies, measuring emissions, identifying reduction opportunities, and supporting implementation. Depending on the provider, services can cover Scope 1, 2, and 3 emissions, carbon accounting, supply-chain decarbonization, climate risk, sustainability reporting, renewable energy, and digital transformation. Recent data highlights the challenge of accurate emissions reporting, with 69 FTSE 100 companies revising previously reported climate metrics in the past year, including changes to Scope 3 data.
The market includes global consulting firms, specialist sustainability organisations, and technology-led transformation companies. This list highlights 7 companies to consider in 2026, with Brysa included first for its relevance to the technology and business-transformation side of sustainability initiatives.

How to Choose a Net Zero Consulting Company
1. Net Zero Strategy
Look for a consultant that can translate climate commitments into measurable objectives, timelines, responsibilities, and practical implementation plans.
2. Carbon Measurement
Reliable emissions data is essential. Assess whether the provider can establish emissions baselines and create processes for collecting, validating, managing, and reporting carbon data.
3. Scope 1, 2 and 3 Emissions
Confirm whether the consultant can address the organization's relevant emissions categories:
- Scope 1: Direct emissions from owned or controlled sources
- Scope 2: Indirect emissions associated with purchased energy
- Scope 3: Other indirect value-chain emissions
Scope 3 can require extensive supplier, procurement, logistics, and operational data.
4. Decarbonization
A net zero strategy should identify practical emissions-reduction opportunities across energy, operations, procurement, products, facilities, logistics, and supply chains where relevant.
5. Sustainability Reporting
Organisations should assess the consultant's experience with sustainability reporting, data governance, disclosure requirements, and the systems needed to maintain reliable reporting data.
6. Technology and Data
Technology can support emissions data collection, reporting, automation, analytics, dashboards, and integration with existing enterprise systems.
This is particularly relevant when a business needs to connect sustainability-related processes with CRM, finance, operations, procurement, or other business platforms. Technology providers such as Brysa can complement specialist sustainability consultants in this area.
7. Industry Expertise
Net zero requirements vary by industry. A manufacturing company may have very different emissions sources and transformation requirements from a financial-services or technology company.
8. Implementation Capabilities
A strategy is only useful when it can be implemented. Evaluate whether the provider can support technology deployment, process changes, organisational transformation, data management, and ongoing measurement.
Final Thoughts
Net zero transformation requires a combination of strategy, emissions data, operational change, technology, and implementation. The most suitable consulting partner depends on the organization's industry, climate objectives, emissions profile, reporting requirements, and internal capabilities.
Accenture, Deloitte, PwC, and McKinsey & Company combine sustainability with broader strategy and transformation services. ERM provides specialist climate and environmental expertise, while Capgemini brings together sustainability, data, AI, and digital transformation.
Brysa serves a different but complementary role. Its focus on AI, Salesforce, workflow automation, data integration, and digital transformation can help organisations modernise the technology and business processes supporting broader transformation programs.
Businesses looking to improve their technology infrastructure, automate workflows, or connect business systems can explore Brysa's Salesforce consulting and AI transformation capabilities as part of a wider digital transformation strategy.
