When looking to understand an organization's environmental impact, two concepts consistently come up: the Carbon Footprint assessment and the Life Cycle Assessment (LCA). Although similar in their goal—evaluating and reducing greenhouse gas (GHG) emissions—these two approaches differ in their scope, methodology, and application.
So, how do you choose between an LCA and a Carbon Footprint assessment? Can they complement each other? Here is what you need to know to effectively guide your climate strategy.
The Bilan Carbone® is a method developed by ADEME to measure the carbon footprint of a company by quantifying the greenhouse gas emissions generated by its activities.
It is a key step in any decarbonization strategy, providing a precise map of emission sources and the room for maneuver to reduce them.
The calculation is based on the international classification of emissions into 3 scopes:
👉 Scope 3 is often the largest and most complex to estimate, but it is essential for a complete picture.
Also known as BEGES, the GHG assessment is mandatory in France for:
- Companies with over 500 employees
- Local authorities with over 50,000 inhabitants
- Certain public entities
It covers at least scopes 1 and 2, and must include a transition plan. Publication on the ADEME website is also mandatory.
Unlike the BEGES, the Bilan Carbone is voluntary, more comprehensive (it includes Scope 3), and is often part of a CSR strategy or decarbonization plan.
It helps you:
- identify your main emission sources
- sustainably reduce your impact
- prepare for upcoming regulations (CSRD, EU taxonomy, etc.)
📅 Validity: 4 years for companies / 3 years for public entities.
A well-executed Bilan Carbone helps you:
- Understand your actual impact
- Cut costs through energy savings
- Anticipate regulatory and economic risks
- Boost your CSR image with clients, partners, talent, and investors
- Rally your teams around a meaningful project
- Access public funding, such as BPI’s Diag Decarbon’Action (up to €4,000 in subsidies)
An LCA is a standardized method (ISO 14040/44) that evaluates the environmental impact of a product or service throughout its entire life cycle, from raw material extraction to end-of-life.
It is a multi-criteria approach (GHG, water, resources, biodiversity, etc.) used primarily to calculate a Product Carbon Score.
- Meet the expectations of customers and public buyers
- Identify eco-design opportunities
- Anticipate environmental labeling requirements
- Stand out in the market
LCA and Carbon Footprint don't compete; they complement each other. The former provides a product/service view, the latter a company view. Together, they form a strategic duo for any business committed to the low-carbon transition.
