GDP

Plan

1- Physical/material growth

2- Economic growth and

"Rebound effect"

3- Sustainable Decrease

(of products and services)

Free time for ourselves and others, equity, health, nature, security, art, culture ...


1 physical material growth l.jpg
1- services)" Physical/material growth

=

More cars, more houses, more factories and mines...

=

More petrol, more coal, more electricity, more wood,more urbanised areas…

=

Increased extraction of natural resources

Extraction

Waste and pollution


Slide6 l.jpg

“The true defence of the environment should be centred on the global rate of resource exhaustion (and on the pollution rate linked to it).”

Nicholas Georgescu-Roegen


Slide7 l.jpg

Realistic hypothesis : the global rate of resource exhaustion (and on the pollution rate linked to it).”

in today's world, we extract

twice too much


Slide8 l.jpg

  • With a fair right to world consumption, the global rate of resource exhaustion (and on the pollution rate linked to it).”

  • and considering demographic growth,

  • we will extract 12 times too much in 2050.


Slide9 l.jpg

With a material growth of 2% per year, the global rate of resource exhaustion (and on the pollution rate linked to it).”

we will extract 30 times too muchin 2050.


Slide10 l.jpg

At an institutional level the global rate of resource exhaustion (and on the pollution rate linked to it).”

  • A factor2 or 4 reduction has been mentioned in some political programs e.g. in Austria, Germany, Japan, Sweden and the Netherlands.

  • A “net reduction of theexploitation of natural resources” is part of the program of the EU.

  • Indicators of natural resource extraction are developed by EUROSTAT, UNEP.


2 economic growth and rebound effect l.jpg

2- Economic growth and Rebound Effect the global rate of resource exhaustion (and on the pollution rate linked to it).”


I pat i ecological impact ehrlich holdren 1971 3 solutions for the material decrease l.jpg
I=PAT the global rate of resource exhaustion (and on the pollution rate linked to it).”(I = ecological impact)Ehrlich & Holdren (1971)3 solutions for the material decrease :

  • (act on P(Population) => lower birth rate)

  • act on A (Affluence) => frugality

  • act on T (Technology) => efficiency


Slide13 l.jpg

Faster!! the global rate of resource exhaustion (and on the pollution rate linked to it).”

Cheaper!

No effort !!

Safer!!

Ecological!!

Smaller!!

Lighter!!

Better for health

A few words of advertising


Always consuming more l.jpg
Always consuming more : the global rate of resource exhaustion (and on the pollution rate linked to it).”

  • more flights,

  • more cars, heavier and more powerful, travelling longer distances,

  • more heating and more air conditioning in larger living spaces,

  • more exotic products,

  • more land sealed underneath concrete or asphalt,

  • more products and services in economic terms.


And impacts increase l.jpg
… and impacts increase : the global rate of resource exhaustion (and on the pollution rate linked to it).”

  • increase of CO2 emissions,

  • air pollution unresolved,

  • decrease of biological diversity,

  • higher consumption of

    • spaces

    • materials

    • energies

  • cultural standardisation,

  • increasing social imbalance.


Two main reasons l.jpg
Two main reasons the global rate of resource exhaustion (and on the pollution rate linked to it).”

  • Rebound effect that create an increase of consumptions

  • Pollution export


Slide17 l.jpg

Cars that consume less the global rate of resource exhaustion (and on the pollution rate linked to it).”

Computer Miniaturisation

Less

petrol costs

Less consumption, reduced costs

We drive further thanks to

money savings

We can buy

more computers

Rebound effect linked to economic efficiency

Innovations

Efficiency gains

Rebound


Slide18 l.jpg

Acceptable travelling time does not decrease the global rate of resource exhaustion (and on the pollution rate linked to it).”

Acceptable pollution does not decrease

Faster transportation

Recycled

paper

Less time spent per km

Less pollution per sheet

The saved time enables us to travel further

We can consume more paper

Growth logics

Innovations

Efficiency gains

Rebound


Slide19 l.jpg

the global rate of resource exhaustion (and on the pollution rate linked to it).”

We do not want to consume more because our limits are reached

Product (or service) innovation

Rebound effect: product (or service) improvements enable us to increase our consumption.

Rebound effect


Rebound effect linked to frugality l.jpg

We heat the house less the global rate of resource exhaustion (and on the pollution rate linked to it).”

Savings on heating costs

We can fly

to Dakar

Rebound effect linked to frugality


Material and economic decrease l.jpg

3- Sustainable decrease the global rate of resource exhaustion (and on the pollution rate linked to it).”

(of products and services)

=material and economic decrease

Reducing what reduces our well-being


S olutions for the sustainable decrease l.jpg
S the global rate of resource exhaustion (and on the pollution rate linked to it).”olutions forthe Sustainable Decrease

Individual actions:

  • Progressive adjusting of consumption limits: "frugal innovation" of lifestyles

  • Information research

Collective actions:

  • Reduction of primary material extractions at the origin

  • Setting consumption limits democratically

  • Information on rebound effect on ecological product


Frugal innovation of lifestyle l.jpg
«  the global rate of resource exhaustion (and on the pollution rate linked to it).”Frugal innovation »of lifestyle

- adjusting revenues by adjusting paid working hours,

- adjusting living space to true needs,

- adjusting the time linked to consumption: taking back our time,

- adjusting ecological consciousness,

- adjusting the acceptable danger for ourselves and others,

- adjusting the acceptable toxicity for ourselves and others.


Slide24 l.jpg

Reducing our the global rate of resource exhaustion (and on the pollution rate linked to it).”

money needs, increasing our free time by working less

Transportation that consume less

Less costs

We need to work less

Economical debound effect

Innovation

Efficiency

gains

Debound


Slide25 l.jpg

Reducing acceptable pollution the global rate of resource exhaustion (and on the pollution rate linked to it).”

Recycled

paper

Less pollution per kg of paper

We improve the environment by consuming less kg of paper

Ecological debound effect

Innovation

Efficiency gains

Debound


Limiting extraction at the origin l.jpg
Limiting extraction the global rate of resource exhaustion (and on the pollution rate linked to it).”at the origin

  • Setting of progressive extraction quotas: material input certificate

  • Setting progressive importation quotas

  • Taxes and removal of subsidies to extraction

  • Setting areas protected from extractionsor further destructions

  • Less excavators

  • Less explosives


Frugal innovation of products and services l.jpg
« Frugal innovation  » the global rate of resource exhaustion (and on the pollution rate linked to it).”of products and services

  • Designing technical limits to consumption

    • technical limitation of speed ; limitation of roads capacity ; favouring proximity with the internet...

  • Favouring the products and activities leading to debound

    • utilitarian cycling, gardening, hiking, train travelling, sharing of goods, solar heating, packaging with deposit...

  • Limiting the products leading to rebound

    • cars and trucks, one-way packaging, TGV, motorways...


Slide28 l.jpg

Limiting buying the global rate of resource exhaustion (and on the pollution rate linked to it).”capacity:

  • Redistribution of work (and free-time) as well as revenues,

  • Ecological taxes,

  • Reduction of paid working hours.


Decrease is possible at the l ocal level l.jpg

Decrease is possible the global rate of resource exhaustion (and on the pollution rate linked to it).”at the local level

Let us imagine and invent a new economic and social system based on the economical decrease.
