Are You a Circular Economy and Climate Change Expert?

Study Notes

The concept of circular economy was developed in 1976 by Pearce and Turner in their book "Fundamental Concepts of Environmental Economics".
Circular economy is a closed system of interactions between the economy and the environment that aims to respect ecological principles in resource utilization.
It involves a production model that uses existing resources and all their biological and chemical components to reintegrate them back into the economic cycle through reuse, repair, regeneration, and recycling.
The main objective of circular economy is to maintain the value of goods, materials, and resources used in production in the economic cycle as long as possible.
Circular economy promotes a just, social, collaborative, and sustainable economy that optimizes resources, materials, and waste to produce goods and services.
In circular economy, the concept of waste does not exist, as all materials are considered resources that can be reintroduced into the production cycle.
The "3R rule" of circular economy promotes reducing, reusing, and recycling to decrease waste production and contribute to environmental protection and conservation.
Climate change refers to long-term changes in the Earth's temperatures and weather patterns, which affect the balance of nature and pose risks to human and all other life forms on the planet.
Human activities, mainly the burning of fossil fuels and the production of materials like plastic, are the main drivers of climate change, shortening and disrupting natural cycles that took millions of years to occur.
Circular economy can contribute to mitigating climate change by reducing waste, optimizing resource use, and promoting sustainable production and consumption patterns.
