More information on the Carbon Footprint®.
Everyone can take advantage of the benefits of carrying out their Bilan Carbone® and, if necessary, of the financial aid to finance it!
The 2021 Finance Law extends the obligation to carry out a BEGES (Greenhouse Gas Emission Balance) to companies with more than 50 employees receiving funds from the European Recovery Plan. These new footprint calculation obligations come at a price: to raise awareness of the benefits they bring, a number of grants are available to companies to finance them.
What are the benefits of carrying out a Greenhouse Gas Emission Assessment (GHGEA) on a quality online platform?
The European Green Pact, which aims to reduce the EU's GHG emissions by 55% by 2030, will increase the price of carbon. Companies that want to remain competitive and ensure their sustainability must therefore adopt a strategy to reduce their emissions without delay.
Are you committed, moderate or latecomers?
In view of the recent consequences of global warming in France and in the world, it is now unthinkable to deny the reasons: we must ACT!
We answer your questions!
How do I calculate my company's carbon inventory?
Much is often made of calculating a carbon inventory. But it's actually very simple! It is a simple multiplication of activity data (in kWh, unit, litres, €) by an emission factor (average quantity of greenhouse gas emissions for 1 unit of the activity data).
To calculate your carbon inventory, all you have to do is list the data from your activities that directly and indirectly emit greenhouse gases and convert them into greenhouse gases using an emission factor.
Why carry out my carbon inventory?
Apart from regulatory obligations (especially since the decree n°2022-982), carrying out a carbon inventory is an essential step for a company because it makes it possible to identify and list the greenhouse gas emission headings directly or indirectly linked to its activity.
Carrying out your first carbon inventory will enable initial measurement and detection of the main emission headings. This will make it easier to identify potential reduction opportunities and define a low-carbon strategy for your company.
Carrying out regular Carbon Inventories over time will be an opportunity to adjust your action plan and to ensure that your objectives for reducing the environmental impact of your business are met.
What data do I need to provide?
For an accurate measurement of greenhouse gas emissions, it is necessary to identify all of the emission headings of the company. This means it is necessary to carry out an inventory of its activity data:
- Energy consumption (gas, oil, diesel, petrol, electricity, etc. .....)
- Depreciating assets (real estate, fleet of vehicles, computer equipment, furniture, etc.)
- Purchases of goods (raw materials, materials, food, etc.)
- Purchases of services (internet contract, maintenance and installation of equipment, supplies of services, fees, etc....)
- Movement of people: employee commuting, business travel, visitors and customers, etc. .....
- Haulage
- Disposal
- Use and end of life of products sold.
Although it is recommended to be as exhaustive as possible in identifying emission headings, it is possible to start with financial data and to refine the accuracy of the data over time. We recommend that you carry out your inventory in stages, starting with your largest expenditure items first.
How can I reduce my company's carbon footprint?
Reducing the carbon footprint of your company is a multi-step process:
- Carry out an initial assessment of your carbon footprint.
- Identify the most important emission headings, and find ways to reduce them by improving the accuracy of the data used for measurement.
- Involve your suppliers by asking them to calculate the carbon footprint of the goods and services they supply. The measurement will be all the more accurate and you will then be able to implement a responsible purchasing strategy.
- Set up an action plan and a measurement strategy over time to ensure that it is implemented and effective.
