Alexandre VeillyEngineer, carbon studiesBilan Carbone® is the greenhouse gas emissions accounting method maintained by the Association pour la transition Bas Carbone. It measures direct emissions, emissions from purchased energy and emissions from the value chain, then provides the basis for a reduction plan.
We organise data collection with your teams and build an assessment suited to your activities. The analysis helps identify the main emission categories, discuss reduction measures and prepare an action plan.
1We define the study scope, organise data collection and calculate direct and indirect emissions. The analysis presents the main emission categories, data quality and the assumptions adopted.
2We review the data and method from the previous assessment to prepare its update. Changes in scope and calculations are documented so that differences can be interpreted.
3We examine reduction measures with the teams concerned and organise proposals by priority, feasibility and responsibility. The presentation gives decision-makers the information needed to decide.
4We prepare collection materials and indicators for subsequent assessments. Handover to internal leads helps them update data and monitor actions.
Each project concludes with documents your teams can use and keep up to date. The previews below are fictional: they show the format of the documents.
Results by emission category, the scope, sources and main uncertainties.
Data, emission factors and assumptions used, so that the origin of the results can be traced.
Measures studied, their order of priority and the monitoring arrangements defined with teams.
Entities, sites, activities and reference year: we define what the study must cover.
We identify the data to gather and the contacts, then support your teams in collecting it.
Emissions are assessed using documented data and factors. We examine emission categories and uncertainties.
We present the results and work with you on actions, monitoring and the next steps.
