Pathway building tool
This website hosts a pathway building tool based on the DDP Approach that allows to articulate physical and socio-economic transformations to develop new decarbonisation pathways.
You will need from one to a few hours to develop your first pathway, depending on your expertise and knowledge.
Starting from the development of your storyline, throughout eight categories of transformations, you can then visualize your pathway in six graphic categories. At this stage, you can compare your scenario with another one, validate and save its different elements (story, computation, dashboard and graphs) or go back to correct your storyline.
We also offer the possibility for external partners to join and support the community in:
Here is a beta version to build pathways for the passenger transport sector in France.
It will be regularly updated and enriched with new countries and sectors, starting with freight transport.

How to develop your storyline (for more information, click here)
What is a storyline for decarbonization?:Each category of drivers includes between two and four questions.
Each subcategory is composed of “one question” in bold black, “A text of information on the 2010’s situation” in italic grey and two or three “modes of answers”.
For each question, you can choose one of these answers:
A “direct assumption” with a proposed reference value based on a pre-defined pathway
A “direct assumption” with an open choice for the value
“Other underlying assumptions” with the opportunity of an indirect answer.
A reference pathway is used to provide default values for each first answers and it corresponds to the values of one pathway defined with national experts during the development of a case study.
You can answer this question by using model inputs or outputs, international or national benchmarks or expert-based analysis and discussions.
Validation of the storyline:If you do not validate all sections, the default values corresponding to the first answers of each question will be used to compute the graph representations.
If you validate a section and conserve all its pre-defined answers, the “red light” turns into “grey light” .
If you validate a section and modify at least one of the pre-defined answers of the section,the “red light” turns into “green light” .
Summary representations after the development and validation of your storylineLook at all your assumptions and answers summarised in a “Full Story” under the different categories of drivers.
Check some quantitative indicators representing your pathway summarized by the limited number of graphs at the end.

What will be the share of the population living in Metropolitan areas in 2050?
In 2010, about 25% of the population lived in metropolitan areas and 75% in non-metropolitan areas, of which half in suburban areas and the other half in rural areas. The metropolitan areas in France have been defined as: Paris, Departments of the Paris region 92-93-94 and all city centers of “urban poles” with more than 100,000 inhabitants. in 2008 (the smallest city center is the city of Montbéliard with about 25,000 inhabitants).

Constrained mobility for metropolitan households
What will be the average distance travelled for constrained mobility in metropolitan areas in 2050?
In 2010, a French citizen living in metropolitan areas travelled approximately 4,770 km / year to connect his different constrained activities. Constrained activities are defined as work-and shopping and acces to public services like schools, health, sport and other social facilities, where your freedom to decide whether or not to complete this activity is limited.
4,100 km per capita (pkm/cap) for constrained mobility for inhabitants of metropolitan areas. km per capita (pkm/cap) for constrained mobility for inhabitants of metropolitan areas. -
Constrained mobility for non-metropolitan households
How will the distance between constrained activities in metropolitan and non-metropolitan areas change in 2050?
In 2010, a French citizen living in Non-Metropolitan areas had to travel about 27% more than a French citizen living in Metropolitan areas to connect his different constrained activities. This means that the different constrained activities (work, home, going to school and reaching other public services) were further away from each other.
The distance to connect the constrained activities in metropolitan and non-metropolitan areas will be reduced to 10 % in 2050. The distance between constrained activities in metropolitan and non-metropolitanareas will be reduced to % by 2050.

Car ownership model
What will be the motorization rate of households in 2050?
The development of Information and Communication Technologies (ICTs) supports the growth of a collaborative mobility economy and can change the way different transport modes are used. However, the ownership model depends on many other parameters, such as the evolution of households’ size and spending power, the availability of other modes of transport in rural areas, and issues related to social status. In 2010, France was home of 510 cars per 1000 inhabitants, or 31.1 million cars.

What will the car fleet look like in 2050?
In 2010, the car stock was made almost exclusively of liquid fuel cars. Over the period 2001-2010, about 2,2 million vehicles were sold per year, with a stock lifetime of around 14 years.
Cars’ sale , final fuel prices and households’ spending capacity are related to the penetration of new vehicles.ICE = Internal Combustion Engine | BEV = Battery Electric Vehicle | PHEV = Plug-and-Hybrid Electric Vehicle | FCEV= Fuel-Cell Electric Vehicle

What will be the place of electricity and gas in 2050’s mobility ?
In 2010, the vast majority of the 2-3 wheelers was powered with liquid fuels. Bus mobility was supported at 98% with liquid fuels, but there were already signs of what was to come with gas and electric vehicles. Rail passenger kilometers were covered at 80% with electricity and the remaining 20% with liquid fuels. domestic and international air travels were only possible with liquid fuels. We do not enable the choice of electric aircraft or other alternatives to to liquid fuels for jet engines in 2050.
