Footprint & data quality
Organisational boundaries, energy data, emission sources and a traceable calculation structure.
Quality & CO₂ management / CO₂ Performance Ladder
From carbon insight to real reduction.
Understand emissions, define measures and manage reductions in your organisation and supply chain. We help with boundaries, source data, calculations, the reduction approach, communication and audit preparation. The right route depends on your certificate, ambition and tenders.

A practical system.
A clear pathway.
Support for levels 1 to 5 under Handbook 3.1 and the three steps of Handbook 4.0.
We build on what already works, identify what is missing and help implement improvements.

Measures, objectives, supply-chain insight and collaboration suited to the selected edition and ambition.
Management & evidence
Ownership, monitoring, communication and an auditable dossier for the independent audit.
Transition to 4.0
A gap analysis and implementation plan aligned with the current rules and your audit cycle.
EDITION, SCOPE & ASSESSMENT
Be precise about
what you demonstrate.
Levels 1–5 belong to version 3.1. Version 4.0 uses steps 1, 2 and 3. Under the transition arrangements, 3.1 audits are possible until 14 January 2027. We determine in advance which edition and step suit your organisation and contracts.
RTE provides advice and support. The appropriate independent certification or verification body conducts the assessment and decides on the certificate or statement.

work in practice.
Electrification, solar panels, storage and more efficient processes require capital. We connect the reduction agenda to investment estimates, cash flows and decision-making.

From a strong organisation
to a demonstrable commitment to nature.
RTE connects certification support to the Nature-Positive Partner partnership. Partner status recognises the agreed commitment and accountability; it does not certify that your business as a whole is nature-positive.
