【Public Affairs】Building a Sustainable Society: What We Can Do Today for the Future
Hello everyone! In your "Public Affairs" class, you’ve surely heard the term "sustainable society." You’ve likely seen the "SDGs" logo popping up all over the place lately, too. At first, it might seem a bit intimidating, but don’t worry!
In this chapter, we will explore the global rules and key mindsets being adopted to ensure we can continue to live happily on this planet for generations to come. Let's organize the essential points that frequently appear on exams, including the Common Test, in a way that’s easy to understand!
1. What is "Sustainable Development"?
Let’s start with the basics. It’s important to remember the term "Sustainable Development."
■ Definition:
Development that "meets the needs of the present without compromising the ability of future generations to meet their own needs." This was proposed in the 1987 report by the World Commission on Environment and Development (the Brundtland Commission).
■ An easy analogy:
Think of a piggy bank. If we use up all the money inside because we "need it right now," the children born after us will be in trouble. The philosophy of a sustainable society is: "Use only the interest (the surplus) and pass on the principal (Earth’s resources) to the next generation without reducing it."
★ Key Point:
Whenever you see the keyword "future generations" on a test, think of "sustainable development"!
2. Global Progress: Conferences to Protect the Earth's Environment
To protect our planet, countries around the world have held numerous discussions. This timeline often comes up in chronological ordering questions!
① 1972: UN Conference on the Human Environment (Stockholm)
The slogan was "Only One Earth." The Stockholm Declaration was adopted. This was the world's first international conference to discuss environmental issues.
*Fun fact: This triggered the move toward establishing Japan’s Environment Agency (now the Ministry of the Environment)!
② 1992: UN Conference on Environment and Development (Earth Summit / Rio de Janeiro)
The concept of "sustainable development" became well-established here. The Rio Declaration and Agenda 21, a detailed plan of action, were adopted. The UN Framework Convention on Climate Change (UNFCCC) was also signed at this summit.
③ 2015: UN Sustainable Development Summit (New York)
The famous SDGs (Sustainable Development Goals) were adopted here. 17 goals to be achieved by 2030 were established.
④ 2015: COP21 (Paris Agreement)
This is the new rule for climate change measures from 2020 onwards, replacing the Kyoto Protocol. A major characteristic is that "all countries" participate.
(The previous Kyoto Protocol only imposed obligations on developed countries, whereas the Paris Agreement encourages both developed and developing countries to work together.)
【Common Mistake】
The option claiming that "the Paris Agreement only imposes greenhouse gas reduction obligations on developed countries" is wrong! The Paris Agreement's strength lies in the participation of "all countries."
3. Must-Know: The "Three Principles" for Protecting the Environment
They might sound like difficult terms, but the concepts are quite simple.
● Polluter Pays Principle (PPP)
The idea that "those who pollute the environment should pay for the costs of measures and restoration." This was proposed by the OECD.
● Precautionary Principle (Precautionary Approach)
The idea that "if there is a risk of irreversible damage, we should take action immediately, even if it hasn't been 100% scientifically proven." It's about acting before it's too late!
● Common but Differentiated Responsibilities
Environmental issues are a global challenge, but this principle acknowledges that the level of responsibility and the capacity to act differ between developed nations (which have emitted a lot of CO2 historically) and developing nations (which want to grow). This is a consideration for fairness.
4. Actions for a Sound Material-Cycle Society
A society that reduces waste and values resources is called a "Sound Material-Cycle Society." In Japan, there is a law called the Basic Act for Establishing a Sound Material-Cycle Society.
Crucial here are the "3Rs"! They are listed in order of priority:
1. Reduce: Minimize waste at the source (e.g., using your own bag, refusing excessive packaging).
2. Reuse: Use items repeatedly (e.g., using refillable bottles, selling items on flea market apps).
3. Recycle: Reprocess resources (e.g., turning PET bottles into textiles).
★ Study Tip:
It's tempting to think "Recycling is all I need to do!", but the most important step is "Reduce" (creating no waste). Exams sometimes test you on this priority order!
5. Ethical Perspective: Intergenerational Ethics
Finally, a brief philosophical look. The German philosopher Hans Jonas proposed the idea of "intergenerational ethics."
This is the belief that "we, in the present, have a responsibility to leave behind an Earth that future generations can live on." We are essentially "borrowing" the Earth from the protagonists of the future.
【Key Takeaways: Summary】
・Sustainable Development = Development that considers "future generations."
・Remember the flow: 1972 (Stockholm) → 1992 (Rio) → 2015 (SDGs/Paris Agreement)!
・Priority order is Reduce > Reuse > Recycle.
・The "Precautionary Principle" means taking action even if scientific evidence is insufficient.
It might feel like a lot of terminology at first, but if you learn while imagining, "How can we keep the Earth clean by the time I'm 100, or for the generations of children to come?" it will stick in your memory much easier. Good luck! You've got this!
