Towards Post-carbon Cities: Six Contrasting Scenarios

In recent decades, many studies and international gatherings at the highest level have raised awareness among the general public of the serious risks posed, on the one hand, by global warming and, on the other, by the possible exhaustion of fossil fuel resources. In this context, the idea of a transition towards a so-called “post-carbon” society has gradually been gaining ground. This has a number of central objectives: the reduction of greenhouse gases by 2050 to one quarter of their 1990 levels (in the countries of the North), near autonomy with regard to carbon-based energies (oil, gas and coal), an adequate capacity for adaptation to climate change and, lastly, greater attention to situations of energy precariousness.

This is why in 2009 a programme was launched, steered jointly by the Foresight Mission of the French Ecology Ministry and by the French Environment and Energy Management Agency (ADEME), called “Rethinking Cities in a Post-carbon Society”. This programme’s work is still on-going towards a final report planned for 2013. This month, Futuribles is devoting a special dossier to it, coordinated by Jacques Theys, who launched this programme, and Éric Vidalenc who now coordinates it with Nathalie Etahiri.

Their article, which opens this dossier, outlines the approach and thinking at the heart of this study, which provides a deep analysis of the role cities play –or might play– in the promotion of major developments and changes to encourage a post-carbon society. In it, most importantly, the authors present the six transition scenarios that have been developed with the aim of proposing various possible routes to post-carbon cities in 2050 through highly concrete initiatives and measures in the fields of transport and housing policy, on decisions around energy, housing conditions, lifestyles etc. Lastly, they stress a major issue underlying such an ambition –namely, the way that short-, medium- and long-term goals hang together.

Post-carbon Society: Pioneering Cities

In 2009 a programme was launched, steered jointly by the Foresight Mission of the French Ecology Ministry and by the French Environment and Energy Management Agency (ADEME), called “Rethinking Cities in a Post-carbon Society.” The programme’s work is still on-going towards a final report planned for 2013. The idea of a transition towards a “post-carbon” society embraces four main objectives: the reduction of greenhouse gases by 2050 to one quarter of their 1990 levels, virtual autonomy in respect of carbon-based energies (oil, gas and coal), an adequate capacity for adaptation to climate change and, lastly, greater attention to situations of energy precariousness.

As part of the dossier Futuribles is devoting, this month, to this programme, Cyria Emelianoff and Elsa Mor show, in this article, how certain cities have gradually taken this subject on board, developing –often thanks to civil society initiatives and the emergence of networks of pioneering cities at the European level– highly ambitious strategies of transition towards less carbon energy consumption and lower greenhouse gas emissions. Here they outline two concrete cases of cities that are highly active in this field, Hanover and Bristol, showing their aims, the strategies deployed, the levers used and the results obtained. They particularly stress the importance played in these two transitions by the economic and environmental departments coming together on the question, and also by the development of “multi-partner” approaches. They are, nevertheless, critical of the difficulties in establishing proper “multi-scale climate governance” involving –above and beyond these pioneering cities– the regional, national, European and international levels, with a view to a more large-scale post-carbon transition.

Area Plans for “Factor 4”: Trajectories to 2020, 2030 and 2050 in the Tours Conurbation

In 2009 a programme –“Re-thinking Society in a Post-carbon Society”– steered jointly by the Foresight Department of the French Ecology Ministry and the French Environment and Energy Management Agency (ADEME), was launched in France. It is still ongoing and aims to produce a final report in 2013. The idea of a transition towards a “post-carbon” society includes four main objectives: reducing greenhouse gas emissions by 2050 to one quarter of what they were in 1990; near-autonomy with regard to carbon energies (petrol, gas, coal); an adequate capacity to adapt to climate change and, lastly, greater attention to situations of “energy precariousness”.

As part of the dossier Futuribles is devoting to this programme this month, this article represents a highly informative case study of the implementation of an area strategy for transition to “factor 4” –that is to say, the reduction of greenhouse gas emissions by 2050 to one quarter of what they were in 1990. Baratier, Beauvais and Métais show how, largely on the basis of its “Territorial Coherence Plan” (ScoT), the Tours conurbation has set about equipping itself, in a two-stage process (with target dates of 2020 and 2030), to achieve a post-carbon transition by 2050. They outline the key measures and objectives by sector and major energy consumption element, aiming to modify lifestyles in the conurbation so as to make Tours a “low carbon” city, a city of localities. Local public action, which is essential for successfully achieving such a transition, cannot, of course, be effective without convergent efforts at all levels. Lastly, above and beyond this interconnectedness of public policies, the authors stress a number of questions that are equally crucial (in terms of timescales, economic investment, democracy etc.) in the implementation of a “territorial factor 4”.

Controlling Property Rents: Steering Property Rents, the Key to Urban Policy

According to figures from the Abbé-Pierre Foundation, in 2012 almost nine million people in France were affected by the housing crisis (either without a personal place of abode, living in very difficult or overcrowded housing conditions, unable to pay their monthly rent or having, involuntarily, to live in the homes of others). If to these housing difficulties we add the need on the part of local authorities, particularly urban ones, to take account of the new approach to energy and the environment (the fashionable concept of the “sustainable city”) in a decade-long context of very high land and property prices (as compared with household incomes), then French local communities face a stiff challenge. However, Marc Wiel argues in this article that it is not insurmountable, provided that local institutions and those in charge of sectoral policies relating to housing in the broader sense (urban policies, transport policies, housing aid etc.) cooperate closely, with a view to controlling “property rents”.

Marc Wiel begins by showing how the process of urban development is not under control in France –largely because of the way that “property rents” are formed. He prefers this latter term to that of “increase in housing costs” on the grounds that it isn’t the costs of construction or demography or shortage that explain this price-rise. He then stresses the disadvantages in the fields of housing, transport and spatial planning, of not controlling property rents, together with the collective costs that ensue. Wiel proposes a new conceptual framework for grasping the (crucial) interactions between transport and urbanism and enabling the public authorities to correct the imperfections of the market and to influence the choice of location of the various actors (households, businesses, services etc.). Lastly, he formulates a variety of recommendations aimed at regulating the processes of urban development and spatial planning better and more fairly, through transport, movement and housing policies and by way of more collaborative work on the part of the actors concerned and a reform of the institutions in which they operate.

France: Entry Gateways and Flows. Four Scenarios to 2040

Within the framework of the series begun in May 2012, aimed at echoing the “Territories 2040” exercise launched in France by the DATAR in 2009, Nadine Cattan presents the lessons learned by the working group she chaired on “Entry Gateways to France and Territorial Flow Systems.” She begins by detailing the analytical framework within which the group worked: the definition of the different types of flows (linked to mobility and leisure, to the information and knowledge economy, to the economy and finance and, lastly, to energy needs and constraints) and the various categories of gateways related to those flows (“place-gateways” and “corridor-gateways”, “territory-gateways” and “network-gateways”, and, lastly, “individuals-gateways” and “objects-gateways”).

Nadine Cattan then outlines the four major problematics at the heart of the foresight approach so far as these flow systems are concerned –territorialization, responsibility (in particular, the ability to regulate and control the territorial system), attractivity and vulnerability– together with the challenges associated with these. On this basis, 10 processes were identified that can explain the developmental dynamics of the system up to the year 2040. Using various combinations of these, four possible scenarios were identified: a “polarized” scenario characterized by a high degree of mobility at the global level, metropolization and high transport-related energy consumption; a “diluted” scenario involving a reduced quantity of journeys and a dematerialization of exchanges, but high levels of energy consumption within living spaces; an “archipelized” scenario, in which global space is structured around a number of large-scale autonomous nodes, long-haul mobility is limited and energy consumption low, but there are great inequalities; and, lastly, a “fluidified” scenario of a hypermobile, networked society, in which individual mobility increases enormously, but new territorial regulatory frameworks are required.

The Counterfeiting of Hazardous Products on the Internet

More than nine million counterfeit products were seized by the French customs in 2011, among which were a million and a half articles seized from carriers of express goods –in other words, articles from individual Internet orders. This latter figure attests to an expanding phenomenon which is as yet difficult to measure precisely, but could turn out to have serious consequences both for consumers and for certain sectors of the economy: namely, the growing distribution of counterfeit products –particularly, hazardous products– by way of the Internet.

Franck Guarnieri and Éric Przyswa present the main issues here, first recalling the particular context that the Internet represents for counterfeiters, together with the reality of the phenomenon and the inherent dangers. They also stress the difficulty of fighting counterfeit goods on the Internet at the international level, because debate and action are too targeted on the legal aspects (intellectual property in particular) or deal with cybercriminality without really confronting counterfeiting, and are based on a loose conglomeration of institutions that co-operate very little with one another. In this context, and given the prospects they foresee for the “counterfeiting/Internet” combination in the years to 2020, Guarnieri and Przyswa have formulated a number of recommendations for solving the problem. These consist, among other things, in recognizing the increasing overlap between the real and virtual worlds and the difficulty of regulating trade on the Internet. It is, they argue, through organizing “resilience” by way of good security strategies and a cooperative logic that the individuals, companies and institutions concerned will be able to confront the distribution of counterfeit products on the Internet, it being out of the question to eliminate them once and for all.

Low-Density Spaces in France to the Year 2040

Continuing the series begun in May 2012 aimed at reflecting the “Territories 2040” foresight exercise launched in France in 2009 by DATAR, Laurence Barthe and Johan Milian present here the lessons learned by the working group on low-density spaces, of which they were members. After going over the statistical definition of these spaces, how that definition has changed over time and the characteristic typology of the spaces, they give an account of low-density French territories based on four major areas of observation: the different populations involved, the changes to their economic fabric, their powers of attraction and their modes of social regulation.

Stressing that the place of these spaces in the spatial order has changed greatly in recent years, with what were once “territories in difficulty” becoming more attractive territories offering new opportunities, Barthe and Milian outline the five scenarios envisaged for the years to 2040: “Community Archipelagos” (demographic shrinkage and deregulation); “Productive Platforms” (strengthening of productive activities in agriculture, energy and the environment); “Low Density Reabsorbed” (in other words, overtaken by urban sprawl); “Enterprising Systems” (banking on innovation); and “The Urban Areas’ Forward Zone” (these territories becoming part of a more general paradigm of “sustainable towns/cities”).

Barthe and Milian go on to analyse two major challenges for low-density spaces in relation to the more general work carried out as part of Territories 2040: the enhanced capacity of these territories (in other words, their ability to control their destinies and find a place in the overall territorial system) and the ecological development of their resources.

The Residential Economy in France up to 2040

Futuribles is continuing the series, begun in May 2012, which aims to reflect the “Territoires 2040” foresight exercise launched in France by DATAR in 2009. This month’s article in that series is a presentation of the lessons learned from the work of the study group on territories that have a residential and tourism-related economic base. Magali Talandier begins by outlining the importance of the residential economy for the local development of territories. She looks at the question at the heart of this working group’s thinking: “what future is there for the processes of residential and tourist development that are based on the capture of wealth created elsewhere, by virtue of the disconnect between sites of production and sites of consumption?”

Four possible answers have been identified, corresponding to the four scenarios outlined here: “Oases, Urban Domes, Rural Domes” (the scenario involving rootedness in the territory and reduced mobility, against a background of a service-oriented economy); “Spheres of Life or Functional Specialization” (the scenario of the local residential economy in which individuals move from one functional sphere to another with a cautious mobility, but an extension of peri-urban spaces); “Spots or Network Mobility” (combining mobility, fluidity and functional multiplicity of places, against a background of hypermobility and the loss of territorial cohesion); and, lastly, the “Web” or A-territorialization scenario (reduced movement, with multiple, but essentially virtual relationships to places) that marks the end of the residential economy and presents serious risks for social cohesion. Lastly, Magali Talandier details the contribution made by this group’s work on two major issues for DATAR: the quality of territories for a mobile society and the organization of networks and time.

French Metropolitan Systems in the Years to 2040

Continuing the series begun in May 2012 that aims to reflect the “Territories 2040” foresight exercise launched in 2009 in France by DATAR, the national spatial planning agency, Gilles Pinson presents the lessons drawn from the work of the Foresight Group on Metropolitan Systems. After a timely reminder of the objectives of this foresight study – not to predict the future, but to “introduce a little perplexity into public policy networks” – he outlines the questions that framed the exercise: how are we to define a metropolis in France today and what are the major trends at work in the metropolitan systems in the particular context of post-Fordism and neo-liberal globalization? In this way, he shows the extent to which the economic developments at work at the international level modify and structure economic activities, social relations and ways of living and working in the French metropolises.

Drawing on this, Pinson presents the three scenarios developed for the years to 2040: the “Mercapole” scenario, characterized by hyperconnection, the rise of the private sector, the domination of economic interests and actors in the property market, which combines densification at the centre and urban sprawl on the outskirts; the “Archipole”, in which metropolises pay more than due regard to public regulation, but also engage in greater surveillance of citizens, against a background of city densification and respect for the environment; and, lastly, the “Antipole” scenario, a scenario of decoupling from the French economy against a background of the repoliticization of urban issues and local institutions, expressed in the emergence of “heritage” or tourist cities, on the one hand, and cities dominated by social groups developing alternatives to the neo-liberal model on the other. In conclusion, Gilles Pinson stresses the contribution of these scenarios to the thinking of public actors with regard, in particular, to levels of decision-making (European Union, state or cities) and the directions to be taken by policies on spatial planning and development.
