GDP

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
1- 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

slide5
=

An equal quantity of matter exists both before and after... Lavoisier

Extraction

Waste and pollution

slide6
“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
Realistic hypothesis :

in today's world, we extract

twice too much

slide8
With a fair right to world consumption,
  • and considering demographic growth,
  • we will extract 12 times too much in 2050.
slide9
With a material growth of 2% per year,

we will extract 30 times too muchin 2050.

slide10
At an institutional level
  • 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.
i pat i ecological impact ehrlich holdren 1971 3 solutions for the material decrease
I=PAT (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
Faster!!

Cheaper!

No effort !!

Safer!!

Ecological!!

Smaller!!

Lighter!!

Better for health

A few words of advertising

always consuming more
Always consuming more :
  • 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
… and impacts increase :
  • 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
Two main reasons
  • Rebound effect that create an increase of consumptions
  • Pollution export
slide17
Cars that consume less

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
Acceptable travelling time does not decrease

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

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
We heat the house less

Savings on heating costs

We can fly

to Dakar

Rebound effect linked to frugality
material and economic decrease
3- Sustainable decrease

(of products and services)

=material and economic decrease

Reducing what reduces our well-being

s olutions for the sustainable decrease
Solutions 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
« 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
Reducing our

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
Reducing acceptable pollution

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
Limiting extraction 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
« Frugal innovation  »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
Limiting buying 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

Decrease is possibleat the local level

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