NOÉ21

NOÉ21 is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand NOÉ21 rather than just read about it. In short: Noé21 (from the French: Nouvelle orientation économique pour le 21ème siècle, meaning "New economic orientation for the 21st century") is a non-governmental organisation founded in 2003 and based in Geneva. It promotes solutions to climate change.

Key takeaways

NOÉ21 belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NOÉ21 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NOÉ21 from memory before moving on to harder problems.

Reference excerpt

Noé21 (from the French: Nouvelle orientation économique pour le 21ème siècle, meaning "New economic orientation for the 21st century") is a non-governmental organisation founded in 2003 and based in Geneva. It promotes solutions to climate change. Noé21 is a member of the Swiss Climate Alliance, the Alliance for Climate (Alliance pour le climat), of the European Council for an Energy Efficient Economy, of the European Environmental Bureau and of the Climate Action Network. The organisation is also accredited to the United Nations Framework Convention on Climate Change.

Activities Noé21 promotes energy transition to fight climate change. It evaluates solutions (centre of expertise) and advocates them to decision makers (think tank), through research, seminars, animations in schools and public events. Together with the Green Party of Switzerland and Greenpeace, Noé21 is currently evaluating having recourse to the judiciary to protect climate.

Worked examples

Example 1 — a first encounter with NOÉ21

Start with the simplest possible case. Write down what NOÉ21 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to NOÉ21 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about NOÉ21 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of NOÉ21

In research: NOÉ21 appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses NOÉ21 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: NOÉ21 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2003 establishments, Climate change organizations, Environmental organisations based in Switzerland, so understanding it makes those chapters shorter.
In everyday life: Look for NOÉ21 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is NOÉ21 in simple terms?

Why does NOÉ21 matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study NOÉ21?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
