Whose fucking sky is it !
We, the citizens of Europe, are calling for equality in terms of transport sobriety: a flight carbon account that is equal for all Europeans.
We who are more sober will receive money from those who travel more, just to show them the value of the climate (as the first common good) and to anticipate the global carbon account mechanism.
This allocation, reduced by 6% each year, will gradually put a stop to the greenhouse gases produced by air travel!
Is the sky for everyone?
Scientists (IPCC, Copernicus, GCP, IPSL, etc.) assure us that the condition for humanity's survival is a return to planetary limits before 2050 (we are currently consuming two planets a year) and that we need to start with greenhouse gases: we need to reduce the planet's anthropogenic emissions (emissions of human origin) from 54 Gt CO2e at present to less than 15 or 20 in 2050.
Air travel accounts for 5% of this, and is increasing more than all the rest, with worrying disparities: symbolically, it is the first climatic effect to be curbed.
Sign the petition submitted to the European Commission to introduce European climate justice for air travel today, and for all purchases tomorrow.
Because the sky belongs to everyone !
The mechanism: a carbon agency in each country to allocate 500 carbon points to each citizen and local counters where to sell surpluses so that the richest can buy surpluses... but at increasingly high prices.
Because this allocation is renewed each year with 6% less (scarcity) and many climate volunteers will refuse to sell their surpluses, thereby driving up the price of the carbon point. As each plane ticket is nominative, company tickets are subject to the same carbon points, throughout Europe.
SkyBartering
Air transport companies are then subject to the carbon register according to Ademe values to be refined, for example 0.152 kgCO2/km for long-haul flights and 0.187 kgCO2/km for medium-haul flights. If they can demonstrate a smaller footprint, they can submit it to the carbon agency of the country concerned. In this way, they are encouraged to use more economical aircraft and fill their seats better (limit flights).
Some countries may add a tax to the price of buying back surpluses, to finance R&D in the aviation sector. The allocation of 500 points, proposed above, is to be recalculated according to each country's aviation data. It could be 500 points if the country's aviation carbon volume is half the number of inhabitants.
My sky, my carbon
As with the carbon account, the year's allocation cannot be carried over to subsequent years, as it will be renewed automatically. For someone who wants to take a trip every five years, they will spread their carbon budget through an averaging account.
Within two years, every country should introduce carbon accounting for all purchases of products and services, by making carbon registers compulsory for all companies and government departments, and by requiring chartered accountants to check the annual balance between outputs and emissions.
The proposal to sign :

For equality in the skies
We, the citizens of Europe, who have become aware of the climate danger at the heart of the 6ᵉ extinction in progress, ask the European Commission to initiate the CCA aeroplane carbon barter, the Quotaircraft, to give the same right to all Europeans, for example 500 kg of CO2 equivalent per person per year in the same logic as the quantitative carbon account mechanism that could continue the CCA after demonstrating its effectiveness.
In practical terms, each person's 500 carbon points could either be used to reduce the carbon content of flights purchased, or sold at the local counter as a sobriety income, financed by travellers who do not have enough of their quota, at an increasingly high price per carbon point.
To achieve this, each Member State sets up a carbon agency to distribute carbon points and check that there is no fraud. This agency develops carbon counters for sale and purchase to curb carbon growth; following the same logic as the carbon account mechanism, the annual allocation is renewed with 6% less each year, thus fuelling the increase in the price of the carbon point.
We propose that all Member States apply the CCA scheme, while leaving them the option of not following suit immediately, but this would make it impossible to sell plane tickets to other Europeans.
Why Europe
Europe is the trigger point for decarbonisation... It took the initiative in setting up the IPCC to gain a better understanding of the risks associated with global warming. In 2024, we know that humanity generates 54 billion tonnes of CO2 equivalent every year, including 5 billion tonnes for the EU.
We know that within 30 years we will have to return to planetary equilibrium (emitting less than can be absorbed by forests and oceans), i.e. emitting less than one billion tonnes of CO2e per year in Europe.
Europe is also responsible for the first industrial emissions of greenhouse gases, having initiated the coal economy and then the oil economy, and caused the start of the Anthropocene, the current geological era characterised by the fact that it is Man (anthropos) who is changing the planet.
Geographically, Europe is well situated in a temperate zone where the effects of global warming are still limited and will not force its children to migrate as they will on other continents.
Europe initiated the great intellectual evolutions on Earth, with the Renaissance in the 16th century, then the Age of Enlightenment, which was the first to raise awareness of planetary limits, with the work of Marx and Engels, with the regrettable period of colonisation, with the creation of the League of Nations, the United Nations Organisation and then the European Union linking 27 democracies under the banner of "United in Diversity".
The European Union thus has a formidable democratic capacity, being able to entrust citizens with the decisions that are essential for the good of humanity.
In this sense, the European Union is in a position to demonstrate the power of consumers to stimulate businesses to innovate, through the essential point of the carbon account mechanism, namely its leverage effect.
Leverage effect: if 100% of consumers put pressure on carbon content, businesses will cut back to stay in the race! Living with 2,000 kg of CO2 in 2050 will probably be equivalent to our 6,000 kg today (9,000 is the French average, 7,000 is the median, 6,000 is the average for people of modest means).

We will keep the planet habitable for our grandchildren...
