You are the bank
With a very simple principle. When you abat your CO2 emissions, You receive an €O2 credit on your account. No reduction, no €O2 gain.
Simple. To start with perform yourn CO2 footprint. Do you know how much CO2 you emit ?
How many €O2s should I gain ?
Every body needs to perform his own CO2 footprint. Every one then receive an €O2 credit based on his own CO2 reductions.
Few examples of CO2 reductions
Heat pump or biomass boiler
Insulating your home
CO2 evaluation methodology
How to perform my CO2 footprint ?
Step 1 - Informations
You mention with which energy you heat up your house (fuel, gaz, electricity,…), and which cars you own.
Step 2 - Proof of consumption
For cars, mileage certificates (through maintenance bills, technical inspections,...) are requested.
Step 3 - Emissions evaluation
The result is simple, accurate, and pertinent as well: CO2 emissions from transport and buildings represent about half of France's emissions.
Step 4 - €O2 credit
Each year, your emissions are compared to the baseline. If you emit less then the baseline, you mint €O2s, and receive the credit on your CO2 Account. You are the central bank. You are central.
Frequently Asked Questions
What is the methodology used to perform CO2 emission reductions ?
CO2 Account takes into account both, your house and transport emissions.
First your baseline emissions are evaluated over a period of two years. This baseline will serve as a reference to compare with your actual emissions and to compute your CO2 emission reductions.
CO2 emissions are thus evaluated each year after the baseline reference. If actual emissions are below the baseline emissions, you will receive an €O2 credit on your CO2 Account. If your actual emissions are above the baseline, nothing happens.
The value of the baseline emissions is reduced by 0.37% each year, according to the UNFCCC approved methodology. In line with this methodology, you will receive an €O2 credit corresponding to 90% of your CO2 reductions. Finally, emissions factors, i.e. the quantity emitted for the burning of one liter of fuel, gaz,...are those of the France National GHG emission report produced by the CITEPA NGO for the French Government.
What is the scope of the CO2 footprint at CO2 Account ?
We all emit CO2 in various ways in our daily lifes: When traveling, heating our dwelling, eating, buying goods and services, etc. CO2 is present everywhere and it can become very difficult to determine emissions from certain actions.
At CO2 Account, only emissions resulting from your dwelling and transport are taken into consideration. Those emissions represent about half of your emissions and can be easily measured and verified.
In the CO2 footprint evaluationsection, what are the supporting documents used for ?
The supporting documents are used for two things :
• First, verifying the conformity of the information you outline for your house, transport and actions to abat your CO2 emissions.
• Second, we evaluate your real CO2 emissions based on the quantity of fossil energy available on those documents. This is the reason why you need to upload all your house fossil energy consumption bills and your mileage data from your maintenance bills or technical inspections of your cars.
I can not find all requested documents to validate my consumption, what should I do ?
In some cases you might be in a position where you can not find all requested documents to assess your real CO2 emissions.
In this case, please contact us (firstname.lastname@example.org) to explain your situation. In some cases it can be possible to find alternative documents.
If not, it may be easier to shift the dates of your baseline emissions to a period for which you have all documents.
I made energy efficiency work in my dwelling but did not received CO2 emission reduction once my account was validated. Why ?
All energies do not have the same carbon content. Electricity and biomass are considered as carbon free by the methodology used by CO2 Account. It is therefore possible to perform energy efficient action that do not reduce your CO2 footprint. It can also be possible that you consume more energy then before you started your energy efficiency work.
Example 1 : Your house is heated with an electric system. You insulate your house. This energy efficiency action will reduce your electricity bill. However, as electricity is considered as a carbon free energy, you will not reduce your CO2 footprint which is already equal to zero.
Example 2 : When you moved, you swith from a fuel boiler in your former house to a gaz boiler in your new home. Once your CO2 footprint is validated, you do not observe any CO2 emission reduction: you bought a larger house, needing more energy to heat up, and offsetting the potential gain from the energy switch of fossil to gaz.
If you plan to do more energy efficiency work on your new house, you can shift the baseline years of your CO2 footprint, in order to observe reductions in your new home after the refit work.
I thought I had performed actions inducing CO2 reductions. Once my CO2 footprint is performed I see an increase in my CO2 emissions. What should I do ?
Each case is singular, and the answer to this question depends of your intitial situation:
1) You overestimated you actions, and realise once the CO2 footprint is performed that your actions where not sufficiently efficient to reduce your emissions.
Examples: occasional carpooling is often not enough to reduce CO2 emissions from your cars.
2) The so-called rebounce effect offseted your initial gains.
You switched from a standard gaz boiler to a high performance gaz boiler. With the new efficience appliance, you decide to spend the same monthly amount in euro to heat up your house, to increase your confort. For the same cost in euros, your are able to buy more heat thanks to the high performance of the appliance. In total you energy bill is constant, and so is you CO2 footprint.
You bought a car consumming less fuel then the old one. Without you noticing it, you drive more, and spend the same amount in euros to purchase fuel.
3) Some actions do increase your CO2 footprint. Typically, this can be moving into a larger house, or buying an additional car. In this case the best option is to shift the baseline period.
Why is electricity not taken into account in the evaluation of my CO2 emissions ?
The non accounting for emissions resulting from your electricity consumption is not a mistake from CO2 Account. Electricity production emits CO2, even if some production processes have low emissions (nuclear production for example). In France, one electrical kWh emits in between 20 to 40 g of CO2. Far from the 187 g of CO2 for one kWh of natural gaz !
But this is not the reason why electricity is not accounted in your CO2 footprint. The electricity production sector is already subject to Carbon allowances (carbon market or EU-ETS). In order to avoid double accounting of CO2 reductions, CO2 emissions resulting from electricity consumtion are considered equal to zero according to the methodology used by CO2 Account.
Why is biomass not taken into account in my CO2 footprint evaluation ?
Biomass is made of carbon, and emit CO2 when burning. So why is this energy source considered as carbon free ?
To understand this paradox, one has to consider wood as a renewable energy source: the burning of wood do emit CO2, but this CO2 was first captured by the wood during its growth.
Likewise, the carbon cycle lifetime resulting from burning of wood can not be compared to to the cycle of carbon from fossil energies. Fossil energies captured and stocked carbon underground for millions of years. This carbon trapped during million of years is released during combustion in few centuries. It would need again million of years to be captured and transformed into fossil energy. For a tree, this cycle is much shorter, in between 20 to 80 years.
Why my CO2 footprint can not be validated during the year ?
The calculation of your real yearly footprint is made on your real fossil energy consumption. We thus need to get the real consumption at the end of the year in order to proceed to the calculation.
For example, when your house is heated by gaz, you typically receive at the beginning of the year your energy bill, detailling all your consumption for the past year.Your real footprint evaluation will be performed once you have this detailled fossil bill.
I have installed photovoltaic panels / a wind turbine, but I can't outline this information on my CO2 Account.
CO2 Account does not take into consideration electricity in its footprint calculation. We can not thus consider those type of energy efficiency work.
