Session Three Flashcards
How many planetary boundaries have we crossed?
At least four: land conversion, nitrogen and phosphorous loading, biodiversity loss, and climate change
Two fundamental mechanisms of growth
Expansion - growing size
vs
Intensification - growing density
To meet the UN goal and keep warming to less than 1.5 degrees…
emissions need to be reduced by 45% by 2030 and reach net zero by 2050
Are we decarbonizing GDP?
Some countries are, but not fast enough
Myth of Decoupling
relative decoupling: decline in the ecological intensity per unit of economic output. In this situation, resource impacts decline relative to the GDP, which could still be rising.
Absolute decoupling: refers to a situation in which resource impacts decline in absolute terms. Resource efficiencies must increase at least as fast as economic output does and must continue to improve as the economy grows if absolute decoupling is to occur
Relative vs Absolute Decoupling
Relative
- decline in resource intensity per unit of economic output
- increased carbon efficiency but lower than economic growth
Absolute
- resource use declines in absolute terms while economic output rises
- increased carbon efficiency higher than economic growth
Key Takeaways
> The power of exponential dynamics
On a limited planet with limited resources, infinite material growth is impossible. There are intrinsic material and physical limits to growth.
Our societies are not decoupling growth, energy, CO2 or material footprint in absolute terms
We are shifting from an era of abundance to dynamics of scarcity, generating conflicts around the access to resources
GDP does not take into account
- externalities
- non-market transactions
- quality improvement and inclusion of new products
- sustainable growth
- wealth distribution
Green Growth
The current dominant position adopted by international institutions, the EU, and several countries around the world
The concept of growth remains central, and sustainability is viewed as a new competitive market
7 Barriers to Green Growth
- Rising Energy Expenditures
- Rebound Effects
- Problem Shifting
- Underestimated Impact of Services
- Limited Potential of Recycling
- Insufficient and Inappropriate Technological Change
- Cost-Shifting
The A-Growth perspective
GDP growth is incompatible with the ecological imperative, decoupling does not happen
The growth concept is reductive and cannot equate with development and wellbeing
Need to develop an agnostic position towards growth
Degrowth Perspective
Most radical scenario, the intentional limiting and downscaling of the economy to make it consistent with biophysical boundaries
Some measures advocated include: global cap on key resources, work sharing, universal income
BUT this requires a strong social consensus regarding the objectives
This perspective is coherent with planetary boundaries but has a lack of economic and sociopolitical support
To Sum Up GDP
The GDP is problematic and challenged in the context of sustainability
> The prevailing approach today within economic and political spheres is that of Green Growth. Despite the attractive narrative, one strong limitation is its reliance on the concept of absolute decoupling.
> A-growth: relies on a new set of indicators beyond GDP. How to diffuse them?
> Degrowth: are our societies ready for it? What would be the consequences on our lifestyles? How can businesses adapt to it?
Anthropocene
a new era in which humankind has a decisive impact on the dynamics of ecosystems
