Greenhouse gas baselines
Review energy and activity data and develop emissions inventories with documented boundaries, assumptions, emission factors and data limitations.
Impact Zero | Engineering, Energy & Sustainability
Sustainability & Decarbonisation
Connect sustainability objectives with credible engineering and operational decisions. Impact Zero helps organisations understand their emissions drivers, identify feasible reduction measures and sequence investments into actionable programs.
Discuss your projectWho we support: Commercial and industrial facilities, healthcare, education, government and other asset-intensive operations.
Decarbonisation opportunity assessment
Evaluate energy efficiency, heat recovery, electrification, renewable energy and operational changes as potential emissions reduction pathways.
Net-zero and transition roadmaps
Sequence practical measures by technical readiness, dependencies, budget, asset life and emissions impact; distinguish direct reductions from residual emissions.
Sustainability governance and reporting support
Assist with data processes, performance indicators, accountability and technical evidence that can support internal and external sustainability reporting.
Climate and operational resilience
Consider how changing conditions, energy supply, asset performance and infrastructure constraints affect proposed sustainability investments.
Implementation and verification
Support technical scopes, project prioritisation and tracking of energy and emissions performance after measures are delivered.
Our engineering approach
- Confirm reporting boundaries, objectives and data quality
- Establish energy and emissions drivers
- Develop and assess reduction opportunities
- Build a phased, costed implementation roadmap
- Monitor performance and update the roadmap
Frequently asked questions
Is a net-zero roadmap the same as a carbon inventory?
No. An inventory estimates emissions for a defined boundary and period; a roadmap identifies and sequences actions to reduce them.
Can emissions reductions be estimated before implementation?
Yes, as engineering estimates with stated assumptions and uncertainty. Actual reductions should be checked against measured performance.
Does this replace formal assurance or legal reporting advice?
No. Specialist assurance and legal advice may be needed for regulated disclosures; technical work should align with applicable requirements.

Practical engineering questions
What makes a decarbonisation plan implementation-ready?
A decision-ready plan connects a verified baseline to specific engineering options, investment and operational constraints, responsibilities, delivery stages and measurement methods.
