The five essential issues of “ecological planning”

• The implementation of "ecological planning" was entrusted by Emmanuel Macron to his Prime Minister Élisabeth Borne, according to our partner The Conversation.

• This ambitious project aims to set environmental objectives… and to provide the means to achieve them!

• This analysis was conducted by Christian de Perthuis, professor of economics, founder of the “Climate Economics” chair at Paris Dauphine University – PSL.

The concept of “ecological planning”, pivot of Jean-Luc Mélenchon’s program, was taken up by Emmanuel Macron during the intervening period for his second five-year term.

As he announced during a speech in Marseille on April 16, 2022, the re-elected president entrusted this planning to his current Prime Minister, Élisabeth Borne.

Regarding the climate, the implementation of such a project raises five essential questions.

The prerequisite: agree on the right objective

The National Low Carbon Strategy (SNBC), a climate roadmap inherited from the previous five-year term, sets the target of climate neutrality in 2050. This long-term objective is in line with that of the European Union.

To aim for neutrality in 2050, the EU raised its intermediate objective in December 2020, aiming for a minimum reduction of 55% in greenhouse gas emissions between 1990 and 2030, compared to 40% previously.

This decision led to a spectacular increase in the CO2 quota on the European market and to an ambitious legislative package under discussion in the European Parliament: the “Fit for 55”.

The SNBC inherited from the previous five-year term remains set on the intermediate objective of -40% in 2030. The decisions of the French courts in favor of environmental NGOs in the context of the “deal of the century” related to the delay taken at the beginning of the five-year period on this objective.

A delay caught up since, with the help of the confinements imposed by the Covid.

On the other hand, no acceleration in the pace of decarbonization of the economy has taken place.

After the ebb in 2020, emissions in 2021 joined the trend detectable since 2005, which does not lead to a 55% drop in 2030.

The first act of ecological planning will be to re-evaluate the intermediate objective which must be in conformity with our European commitments.

Can we go further?

The Nupes program shows a -65% which questions the means to be implemented to achieve this.

​Energy: demand triptych, renewables, nuclear

As the use of fossil fuels is the source of three quarters of our emissions, the acceleration of the energy transition conditions the achievement of a 55% reduction in emissions by 2030.

On the demand side, this implies more actions promoting energy efficiency and sobriety.

The detailed evaluations resulting from the scenarios of the organization

give the measure of the objectives to be achieved without completely arbitrating on the means to be committed.

On the supply side, the substitution of carbon-free means of production for sources of fossil origin should be accelerated.

Firstly, this requires accelerating the deployment of renewables for which our country is a red lantern within the EU.

This involves clarifying the role of nuclear power, almost all of which will reach 40 years of age in the coming years.

Extending the useful life of this fleet requires an investment estimated at 50 billion euros by EDF.

Abandoning this investment by decommissioning the reactors as they reach 40 years old would deprive the country of most of its low-carbon resources, which are difficult to replace with renewables within the time limits set.

In the long term, what will the existing nuclear fleet have to be replaced with?

The deployment of new EPR-type reactors could not provide carbon-free energy before 2035. Given the dynamics of falling costs of renewables and electricity storage, it is doubtful that this path is justified on the plan. economic.

A matter for urgent debate to introduce economic rationality into ecological planning.

​Initiate the shift towards agroecology

In 2021, agriculture was responsible for one-fifth of the country's emissions, mostly methane and nitrous oxide from crop and livestock practices.

They are not reduced by acting on energy but by changing the methods of agricultural production.

The path leading to it is that of agroecology, which focuses on the diversity of living things, the complementarities between plants and animals, the protection of soils to store organic matter, water and carbon.

The fallout from the war in Ukraine is a powerful reminder of this: the objective is not to produce less, but better and more sustainably by increasing the resilience of agricultural systems in the face of climate change.

France is struggling to initiate the agro-ecological shift.

The European Commission recently revoked the "national strategic plan" aimed at implementing the environmental guidelines of the new CAP.

Emissions of agricultural origin are not declining and the capacity of the natural environment to absorb CO² from the atmosphere has been declining since the mid-2000s. Forests and soils absorbing a decreasing proportion of agricultural emissions, the prospect of climate neutrality s 'distant.

Counteracting these counter-performances must be a priority for future ecological planning.

This implies acting simultaneously on supply and demand, with a variation by territory, essential to develop agricultural and food models that are not compatible with our climate objectives.

The plan as an “uncertainty reducer”

Ecological planning will not place us on linear emission trajectories, as pre-programmed by an omniscient planner.

It is a path of constant learning, with failures that must be corrected and incessant contradictions crossing the social body.

Three principles will make it possible to make the ecological plan a "reducer of uncertainties" according to the formula of Pierre Massé.

It is first necessary to create synergy between the different territorial scales.

A large part of the actions to reduce emissions or to strengthen resilience in the face of global warming can only be carried out at the local level.

The existing planning tools in the regions and municipalities still only play a secondary role.

They must be solidified.

The second principle concerns the proper use of public money which should be reserved for sovereign functions: research and development, low-carbon infrastructure, enhancement of ecosystem services, reduction of inequalities, support for conversions.

To combat the glaring insufficiency of these investments, it is necessary to save on a number of subsidies, including those favoring “green products”, which generate windfall effects and often contribute to increasing social inequalities.

Applying the polluter pays principle, carbon pricing is, along with standards, an essential instrument to encourage all economic players to turn away from fossil fuels.

The dynamic here is European with the strengthening of the CO² quota system.

A crucial component is its extension to all emissions from transport and buildings.

If it takes ecological planning seriously, the French government must defend this aspect of the reform.

​Climate justice, a condition of citizen support

Finally, ecological planning must be based on the support of citizens, for whom it is not enough to tell beautiful stories about the benefits of the low-carbon transition.

Such support is obtained by applying rules of justice based on the triptych of purchasing power, employment, resilience.

The impacts of climate policies weigh more heavily on the budgets of poor households or households far from city centers.

The implementation of ecological planning, in particular via carbon pricing, therefore requires redistributive measures to correct the risks of a decline in the purchasing power of the most vulnerable populations.

The low-carbon transition will cause an acceleration of industrial and agricultural reconversion.

Their financing is the poor relation of the public expenditure directed towards this transition.

Anticipating and financing professional retraining must become a major lever for ecological planning.

Global warming affects more severely the populations that have generally contributed the least to the increase in the greenhouse effect and generates new inequalities.

As the 6th IPCC report reminds us, these impacts will intensify over the coming decades, regardless of the global emissions scenario.

Our "ECOLOGY" file

Ecological planning must therefore include a section on adaptation to the consequences of global warming, another poor relation of climate policies inherited from the past.
