Strategic study: PARIS is entering a new era: towards carbon neutrality in 2050
Cities aspiring to carbon neutrality recognise that to prevent the worst effects of climate change, greenhouse gas emissions must be reduced by at least 80% by 2050. Because urban areas account for nearly three quarters of emissions from people, the achievement of this objective will depend largely on our ability to re-imagine and re-invent the cities to promote economic prosperity, social equity, quality of life and climate resilience.
Ahead of the future revision of its Climate Plan, the City of Paris is leading the way with the launch of a strategic study for the achievement of a low carbon vision of Paris by this date.
The Elioth group, an Egis entity specialising in R&D and EPCM of low carbon innovations (agent), combining Quattrolibri, the Egis Consultancy teams, and Mana has assisted it in this study, allowing the Paris City Council to have an external, independent and impartial view of the issues to consider. The measures proposed by the group should open the debate for a transition to a low carbon city and provide a vision shared by all its inhabitants.
This carbon neutral strategy called for cutting-edge technical and scientific work, both to make the pathways to this reduction more concrete and to model the changes in compensation and sequestration of residual emissions. The major objectives are:
- Transport and Freight: 75% reduction in emissions including -85% for personal mobility
- Consumption: 70% reduction of emissions through food, goods and waste
- Buildings: 75% reduction in emissions including -80% for housing
- Energy: large scale solar-powered heating both within Paris and outside the city
To achieve this, the group has proposed the implementation of flagship measures, including:
- 6 million square meters of solar roofs
- Renovation of up to 75% of the existing housing stock
- 150 hectares of urban agriculture
- 75% semi-vegetarians (or flexitarians) in 2050 (diets with a lower content from animal sources, favouring “vegetarian, local, seasonal”.)
- Halving of the household waste per capita
- Half the number of cars, and twice as full, in shared mode
- A massive shift to electric cars
- 52 weekends without cars per year by 2050
- Transformation of the ring road into an urban boulevard
- 5 times more cargo travelling via the Seine
The conclusion of the group is unambiguous: the prospect of achieving carbon neutrality is within reach of the Paris City Council. That prospect justifies all the energy and vitality of its recommendations but also the radical nature of some of them.
