Sustainable Living and Climate Awareness

What you will achieve

By the end of this course you will be able to look at your own household and explain, in plain language, where most of its emissions and most of its avoidable costs come from. You will not need a science background to get there.

Concretely, you will be able to:

• Explain the greenhouse effect and why CO2e is the unit that lets us compare a steak, a flight, and a new jacket on the same scale.
• Read a carbon footprint number and understand what it does and does not include, including the idea of scopes.
• Rank the "big four" of everyday emissions (food, home, travel, shopping) by impact, so you spend effort where it actually moves the number.
• Run fair swaps: changes that cut emissions while keeping the meal, the comfort, or the budget intact.
• Spot greenwashing when a product or label makes a vague or misleading claim.
• Build a simple household plan that cuts both emissions and bills, and that you can realistically keep up.

The through-line is pragmatism. We prioritize high-impact, money-saving changes over guilt and perfection. A household that does three things well beats one that attempts twenty and quits.

Who this course is for

This is a beginner course. There are no prerequisites and no prior knowledge expected. If you can read a utility bill and follow a recipe, you are ready.

It suits you if:

• You want the fundamentals of climate science and everyday emissions without jargon or politics.
• You are more interested in what to do next than in being told you are doing it wrong.
• You want changes that pay back, not just changes that feel virtuous.
• You are curious whether a product's "eco" label means anything.

It is not a deep technical or policy course. We stay close to the household, the shopping basket, and the monthly bill.

Course roadmap

Module 1: Climate Science in Plain Terms You start with the greenhouse effect explained without the jargon, then learn what CO2e means, how scopes split a footprint into parts, and how to read a carbon footprint number without being fooled by it. A checkpoint quiz confirms the foundations before you move on.

Module 2: The Big Four: Food, Home, Travel, Shopping This is the heart of the course. You work through food footprints (meat, dairy, waste, and fair swaps), then home energy and water savings that pay back, then transport and shopping, where the spread between choices is widest. Worked examples sit inside the lessons so you see the numbers, not just the advice. A checkpoint quiz closes the module.

Module 3: Waste, Greenwashing, and Habits That Stick You finish with waste, repair, and reuse through worked examples, then sustainable purchasing and how to spot greenwashing. The last lesson pulls it together into a household plan that cuts emissions and bills at the same time. A final checkpoint quiz wraps up the course.

How the course works

The course runs about 178 minutes across 11 lessons. That is roughly three hours end to end, and most lessons are short enough to finish in one sitting.

Lessons mix formats:

• Theory lessons give you the short explanation and the key idea, usually in a few paragraphs.
• Worked examples live inside the theory lessons, so you see a real number or a real swap worked through rather than an abstract rule.
• Checkpoint quizzes at the end of each module test whether the fundamentals landed.

There is no separate lab or project. The practice is built into the lessons themselves.

How to use it: the course is designed to be taken in order, because each module builds on the vocabulary of the one before. That said, if you already understand the greenhouse effect and CO2e, you can skim Module 1 and start with Module 2, which is where most of the practical value sits. The checkpoints are a good way to test whether skipping a section was safe.

One suggestion before you start: have a recent energy bill and a rough sense of your weekly groceries nearby. The examples are easier to apply when you can compare them to your own numbers.
