How to Calculate Your Household's Eco Score

Understanding your household's environmental impact starts with measurement. You can't improve what you don't measure. The Eco Score quiz breaks down your household's sustainability into actionable categories, giving you a clear picture of where you stand and what to focus on first.

What the Household Eco Score Measures

Your household eco score evaluates five key areas that together account for over 90% of a typical home's environmental footprint:

• Energy consumption: How much electricity and gas your home uses, what sources it comes from, and how efficient your appliances are. The average US household uses about 10,500 kWh of electricity per year.
• Water usage: Daily water consumption, irrigation habits, and fixture efficiency. Most homes use 300 gallons per day, but efficient households can get that below 150.
• Waste production: How much trash goes to landfill versus recycling and composting. The average American generates 4.4 pounds of waste daily.
• Transportation: Commuting habits, vehicle types, and air travel frequency for all household members.
• Food and consumption: Dietary choices, food waste, and purchasing habits including fast fashion and single-use products.

Step-by-Step: Taking the Quiz

1. Gather Your Data

Before starting, collect your recent utility bills (electricity, gas, water), estimate your weekly grocery spend, and think about your commuting patterns. Having actual numbers makes your score much more accurate than guessing.

2. Answer Honestly

The quiz works best when you answer based on what you actually do, not what you aspire to do. There's no judgment here. The point is to get an accurate baseline so you can track real improvement over time.

3. Review Your Results

Your score breaks down into categories. Most people discover that one or two areas dominate their footprint. For 60% of households, transportation and home energy are the biggest contributors. For others, diet or consumption patterns might be the surprise leaders.

Interpreting Your Score

Eco Score uses a 0-100 scale:

• 80-100: You're already living sustainably. Focus on maintaining habits and advocating for systemic change.
• 60-79: Good foundation. A few targeted changes could make a big difference.
• 40-59: Average range. Most households land here. There's significant room for improvement with relatively easy changes.
• 0-39: High impact lifestyle. The good news is that small changes will produce dramatic improvements in your score.

What to Do With Your Results

Focus on your lowest-scoring category first. That's where small changes yield the biggest gains. If your energy score is low, switching to LED bulbs and adjusting your thermostat by 2 degrees can improve it by 15-20 points. If transportation is your weak spot, even one day of remote work per week can shift the needle significantly.

Retake the quiz every 3-6 months to track progress. Households that retake regularly improve their scores by an average of 12 points within the first year. That translates to roughly 1.5 tonnes less CO2 per year. Real numbers, real impact.
