You are here because you want to make a difference. Perhaps you watched a documentary about the ocean, read a news article about floods, or simply looked at the pile of plastic in the trash and thought: “there must be a better way.” Whatever triggered it, the desire to live more sustainably is one of the smartest and most generous impulses a person can have — for the planet and for themselves.
The good news is that you don’t have to turn your life upside down on the first day. Sustainability is not a perfect state achieved all at once; it is a daily practice, made up of small and consistent choices. According to the Intergovernmental Panel on Climate Change (IPCC), changes in household consumption patterns have real potential to significantly reduce greenhouse gas emissions — and it starts with the everyday decisions of people like you.
This checklist is designed for those taking their first steps. It is practical, honest, and free of complicated jargon. Let’s take it step by step.
Why a Sustainable Living Checklist Works
Lists work because they turn abstract intentions into concrete actions. “Living sustainably” is too broad an idea for the brain to execute directly. “Take a reusable bag when going to the market today” is a task that fits into the day.
Moreover, the checklist allows you to measure your progress. When we check off an item, the brain releases dopamine — that feeling of reward. This creates a positive cycle: each small sustainable action motivates the next. Over time, what seemed like an effort becomes a habit.
The goal here is not guilt, but direction. Use this guide as a map, not as a list of judgments.
Home Checklist: Reduce Energy Consumption at Home
Housing is one of the biggest environmental impact points for a Brazilian family. Lighting, appliances, and water heating account for a considerable share of residential electricity consumption in the country.
Items to check:
- Replace incandescent or fluorescent bulbs with LEDs (LEDs consume much less energy for the same amount of light)
- Unplug devices when not in use — “standby mode” consumes energy even when the device appears off
- Check the Procel seal on appliances for the next purchase (the more “A”, the more efficient)
- Take advantage of natural light during the day before turning on lamps
- Set the electric shower to “summer” mode in hotter months
- Check for leaks in faucets and water tanks — a drip per second can waste hundreds of liters per month
How to Identify “Energy Vampires” in Your Home
- Observe which devices are constantly on standby (TV, microwave, chargers)
- Use a consumption meter (sold in electronics stores at affordable prices) to measure the actual consumption of each item
- Prioritize unplugging those that consume the most when not in use
- Consider power strips with switches to turn off multiple devices at once
Waste Checklist: Less Waste, More Intelligence
Brazil generated over 80 million tons of urban solid waste in 2023, according to data from the Solid Waste Panorama in Brazil, published by Abrelpe. A significant portion of this volume comes from households. The good news: you can directly act on what leaves your home.
Items to check:
- Separate recyclable waste (paper, plastic, glass, metal) from organic waste
- Find the nearest voluntary delivery point (PEV) or selective collection to your home
- Avoid unnecessary packaging when shopping (prefer bulk products or with minimal packaging)
- Reuse jars, bags, and packaging before discarding
- Do not pour used cooking oil down the sink or drain — it contaminates water and can clog sewage networks
What to Do with Used Cooking Oil
Used oil is one of the most poorly disposed wastes in Brazilian cities. The simplest alternative is to store it in a closed PET bottle and take it to a collection point — many supermarkets and gas stations accept it. Another creative option is to turn it into homemade soap: besides giving a use to the waste, you save on cleaning products.

Food Checklist: The Plate is Also Political
The way we eat has a direct impact on the environment. Food production is responsible for a significant share of global greenhouse gas emissions, according to IPCC data. But dietary changes don’t have to be radical to make a difference.
Items to check:
- Reduce (not necessarily eliminate) beef consumption, especially of unknown origin
- Buy more fruits, vegetables, and greens from local producers or at farmers’ markets
- Plan meals for the week to avoid food waste
- Store food properly to prolong its shelf life
- Compost organic waste (peels, coffee grounds, fruit scraps) — even in an apartment, there are compact and odorless composters
How to Set Up a Simple Composter at Home
- Choose a container with a lid (it can be a plastic box with holes)
- Alternate layers of organic waste (wet) with dry material (sawdust, shredded cardboard, dry leaves)
- Mix lightly with each addition to aerate
- In a few weeks, you will have humus to use in pots or gardens
- Avoid placing meat, dairy, or fats in the home composter
Bathroom Checklist: Sustainability in Daily Personal Life
The bathroom is one of the rooms with the greatest potential for change — and also where a lot of disposable plastic accumulates. Shampoos, conditioners, soaps, toothbrushes: each can have a more sustainable version.
Items to check:
- Switch the plastic toothbrush for a bamboo one (biodegradable)
- Try bar soap instead of liquid soap in plastic packaging
- Opt for solid shampoo or in recyclable/refillable packaging
- Take shorter showers (reducing by 2 minutes can save dozens of liters per shower)
- Turn off the tap while brushing your teeth
If you want to deepen the swaps in the bathroom, the article Being Eco-Friendly Costs Less Than You Imagine shows that many sustainable substitutions are cheaper in the long run.
Consumption Checklist: Buy Less, Buy Better
One of the most powerful forces of sustainability is simply buying less. The linear economy — produce, use, discard — pressures natural resources, generates waste, and emits carbon at all stages. Every item you choose not to buy has a real impact.
Items to check:
- Before buying something new, ask: “Do I really need this? Can I rent, borrow, or buy used?”
- Opt for products with greater durability instead of the cheapest and disposable ones
- Research brands with verifiable environmental commitment (real certifications, not just marketing)
- Prioritize thrift store clothes or swaps with friends before buying new pieces
- Avoid fast fashion — the textile sector is one of the most polluting in the world, according to UN Environment reports

Transportation is one of the main sources of CO₂ emissions in Brazilian cities. Small changes in commuting, when added up, have a real collective impact.
Items to check:
- For short distances (up to 2 km), prefer walking or biking
- Use public transport whenever possible instead of individual cars
- If using a car, consider carpooling (sharing apps) to split the emissions
- Regularly check tire pressure (under-inflated tires increase fuel consumption)
- Plan routes to avoid unnecessary detours and optimize travel
How to Maintain Consistency and Not Get Discouraged
The biggest obstacle for those starting to live more sustainably is not a lack of information — it’s the feeling that “it won’t make any difference.” This thought is understandable but mistaken.
Climate change is a systemic problem, yes. But systems are made of parts. When you change a habit, you also change the market around you (by choosing sustainable products, you signal demand to companies), influence those around you, and strengthen your own coherence with the values you believe in.
Tips for keeping the pace:
- Start with just 3 items from the checklist per month, not all at once
- Record your changes — a simple notebook or a note on your phone will do
- Celebrate progress, no matter how small it seems
- Connect with people who share these values (local groups, online communities)
- Remember: perfection is not the goal. Progress is.
Living sustainably is not about giving up comfort — it’s about redefining it. It’s understanding that true well-being cannot come at the expense of the air, water, and biodiversity that make life possible. Each item checked off this checklist is a concrete step in that direction.
You don’t need to solve everything today. Choose one or two items from this list, put them into practice this week, and see how you feel. Then come back here and check off another one. This is how habits are formed step by step — and this is how the planet thanks you.
