Andrea Innocenti The 2030 Agenda speaks to governments and businesses, but change also comes from actions repeated every day. To move from intentions to results, measurement is needed : setting simple numbers, monitoring them consistently, and adjusting course. With four areas— energy , mobility , waste , and personal finance —the SDGs become a traceable routine.
This guide translates the goals into minimum indicators and proposes monthly micro-goals, along with clear criteria for choosing apps and tools that can calculate the footprint and show real progress.
No complex formulas: just essential, verifiable data that helps you make decisions.
From the SDGs to everyday life: choose 4 key indicators
The key is to limit yourself to a few numbers, always the same. A basic set includes: 1) kWh of electricity and cubic meters of gas per person; 2) km by mode (car, public transport, bicycle/foot) and estimated CO₂ per trip; 3) kg of residual waste per capita and recycling rate; 4) share of budget/investments aligned with sustainability.
Each indicator has a baseline (average of the last three months) and a monthly target : -10% consumption, +20% sustainable travel, -1 kg waste, +5 percentage points responsible budget.
To maintain control, a single dashboard is best : a spreadsheet or app that aggregates data and shows trends. The metric is only as good as it is SMART.
: specific, measurable, accessible from your data, relevant to the SDGs and time-limited (month on month).
Domestic energy: kWh, gas, and degrees at home
Energy impacts multiple SDGs. Operational indicators include: kWh/month per capita , m³ of gas , and thermostat setpoint . Helpful tools include the supplier's portal or an app that reads bills and, if available, meter data. Micro-goal M1: -10% kWh compared to the baseline with three verifiable measures: temperature at 19–20°C in winter, standby power below 1W (slippers with a switch), and washing at 30°C.
For gas, a concrete step is scheduling : reduced time slots and differentiated environments. Those with photovoltaic systems can shift energy-intensive loads to production hours. Emissions estimates are provided by many energy apps; rather than the absolute value, month-over-month variation is important . An additional metric: kWh self-produced and self-consumed, useful for assessing the system's true benefits.
Mobility: km, modes and CO₂ per journey
Personal mobility is measured in kilometers per mode and estimated CO₂ per trip. A trip tracking app automatically recognizes and classifies trips; alternatively, a manual weekly log is sufficient. Practical benchmarks: combustion-fueled cars 120–180 g CO₂/km, public transport 20–80 g CO₂ per passenger-km, cycling and walking close to zero. Micro-goal M1: +15% km by public transport or bicycle compared to baseline.
For car users, two metrics are immediately helpful: occupancy rate (people on board/travel) and eco-driving (fuel consumption in liters per 100 km). A realistic goal is to increase the average occupancy above 1,5 and reduce fuel consumption by 5% with smooth driving and proper tire pressure. The combination of fewer kilometers driven and more passengers reduces the vehicle's footprint without drastic sacrifices.
Waste: kilos per capita and recycling rate
Two numbers are enough to guide your choices: kg/month of residual waste per person and % of waste sorted . To estimate these, use a household scale to calculate the weekly waste and calculate the proportion of recycled waste. A useful target is waste under 5–7 kg/month per person and waste sorted above 65%.
Practical micro-goals include: switching to filtered water and water bottles (cutting out single-use plastic), choosing refillable packaging, planning meals to reduce food waste , and starting a small home or community compost bin where permitted. An additional metric, valuable for purchasing decisions, is the number of products repaired versus replaced per month.
Personal Finance: Aligning Your Account with the SDGs
Sustainability is incorporated into the portfolio through three indicators: 1) % of monthly budget spent on lower-impact goods/services (repairable, second-hand, renewable energy); 2) estimated carbon intensity of investments (if investing, via intermediary reports or dedicated apps); 3) share of liquidity held with institutions with public environmental policies . Micro-goal M1: reallocate 5% of spending towards circular or highly efficient options.
Helpful tools: budgeting apps that automatically categorize expenses, portfolio footprint calculators offered by some brokers, fund reports with ESG indicators. Even without advanced tools, a simple spreadsheet allows you to mark "aligned" transactions and measure their month-over-month evolution.
Tools and apps: How to choose and connect data
Not all apps are created equal. Minimum criteria: 1) transparency on emissions factors and assumptions; 2) integration with meters, utilities, and transportation services; 3) CSV/Excel export; 4) clear privacy and permission controls; 5) ability to set targets and receive alerts. Tools that show trends , not just specific data, are preferable.
For energy: supplier apps or platforms that automatically read kWh from the meter. For mobility: trackers that distinguish vehicles and recognize recurring routes. For waste: municipal apps for calendars and special disposals, plus a weight log. For finance: budgeting apps with custom categories and, if available, wallet footprint modules. A single dashboard (or even a spreadsheet) connects the four flows and reduces friction.
90-Day Plan: Monthly Micro-Goals and Review
Month 1 : Define the baseline (average of the last 3 months) and activate automatic tracking where possible. Objectives: -10% kWh, +15% sustainable km, -1 kg per capita, +5 pp responsible budget. Month 2 : Consolidate with structural actions — smart thermostat, public transport subscription, rechargeable spending, updated spending categories. Month 3 : Optimize — redistribute electricity loads during convenient hours, weekly carpooling, active composting, review of financial services.
Monitoring is monthly and visual: a graph for each indicator and a traffic light (green if the target is met, yellow if within 5%, red otherwise). If a target is missed, only one corrective measure is implemented at a time to isolate its effect. Those wishing to raise the bar can introduce a fifth indicator: liters of water consumed per person, useful during the summer months.
A next step with a collective impact is joining renewable energy communities or purchasing groups: many municipalities periodically open registration windows and information desks. Monitoring municipal notices and scheduling a meeting allows you to anticipate the timing, estimate the economic benefit, and integrate a new indicator into your dashboard: shared kWh and savings generated per household.
