Understand your environmental impact before deciding where to act. We help you define emissions boundaries, organise activity data and assess lifecycle impacts, creating a clear baseline for analysis, reduction and reporting.

The Measure stage is where effective environmental and ESG operations begin. Before you can prioritise action, validate claims or communicate progress with confidence, you need a clear picture of the impacts across your organisation, assets, products and supply chain. This pillar brings together the services that help clients quantify emissions, define reporting boundaries, assess lifecycle impacts and establish a credible environmental baseline. It is designed for organisations at the start of their sustainability journey, as well as those looking to strengthen existing carbon and ESG data systems.
At this stage, we help clients build robust baselines across Scope 1, Scope 2 and material Scope 3 emissions, while also improving understanding of product and asset impacts through lifecycle assessment. Alongside this, we strengthen the quality, structure and consistency of environmental data to support better decision-making and future reporting. Once measurement is in place, clients are in a far stronger position to move into the next stage of the journey: Analyse, where data is translated into clear priorities and practical direction.
Method and scope are agreed before work begins. Relevant published references include the GHG Protocol standards and guidance and ISO 14064-1:2018 for organisational inventories, and ISO 14040:2006 and ISO 14044:2006 with their applicable amendments for lifecycle assessment. The joint GHG Protocol–ISO corporate standard is under development and is not a replacement already in force.
We help clients establish defensible baselines across organisational emissions, value chain emissions and product-level environmental impacts, creating the foundation for practical ESG action.
From activity data collection to documented assumptions and methodological alignment, we strengthen the integrity of environmental data so clients can move forward with confidence.
Measurement is not just about producing a number. We help clients see where the most material emissions and environmental impacts occur across operations, products and procurement.
Once a robust baseline is in place, clients are ready to move into Analyse, where data is interpreted, prioritised and turned into meaningful business direction.
Carbon footprint measurement identifies and quantifies greenhouse gas emissions within a defined organisational boundary and reporting period. It involves collecting activity data, choosing suitable emissions factors and documenting assumptions. Critical Path can help establish a baseline for carbon management and reporting, using the applicable methodology and making data limitations clear.
Scope 1 covers direct emissions from sources an organisation owns or controls. Scope 2 covers emissions from generating purchased or acquired electricity, steam, heat and cooling. Scope 3 covers other indirect emissions across the upstream and downstream value chain. The reporting boundary and applicable framework determine how sources are included and reported.
Yes. We can help screen relevant Scope 3 categories, identify important data gaps and select appropriate calculation methods. Estimates may use activity data, expenditure or industry averages where the chosen method permits. Assumptions, exclusions and data quality should be transparent, with a plan to improve supplier-specific evidence where it matters most.
A carbon footprint focuses on greenhouse gas emissions. A lifecycle assessment (LCA) can examine several potential environmental impacts across defined stages of a product or service lifecycle. Its coverage depends on the study’s goal and scope. Critical Path can help define boundaries, data requirements and intended uses before carrying out the assessment.
