Sustainable Living in Brussels: How Coliving Reduces Your Footprint

Brussels has set ambitious climate targets — the Brussels-Capital Region aims to reduce greenhouse gas emissions by 40% by 2030 compared to 2005 levels. Achieving this requires changes at every level, including how we live. Coliving, by its very nature, is one of the most sustainable urban housing models. Here's why, and how Brussels' coliving scene is contributing to a greener city.

The Environmental Case for Shared Living

Smaller Per-Person Footprint

A single person living in a one-bedroom apartment in Brussels uses roughly 60-80 square meters of heated, lit, and maintained space. In a coliving arrangement, that same person occupies a 12-20 square meter private room plus a share of common spaces — effectively using 25-35 square meters of total space per person.

Less space per person means:

Lower heating costs — heating is the biggest energy expense in Belgian homes. Shared walls and fewer square meters to heat reduce per-person energy consumption by an estimated 30-50%.
Reduced electricity use — one shared kitchen, one shared living room, and shared laundry facilities mean fewer appliances drawing power.
Smaller construction footprint — fewer total buildings needed to house the same population.

Shared Appliances and Resources

In a traditional setup, every apartment has its own washing machine, dryer, oven, refrigerator, and vacuum cleaner. In coliving, these appliances are shared among 6-20 residents. This means:

Fewer appliances manufactured, transported, and eventually disposed of
Higher utilization rates — a shared washing machine runs full loads rather than half-empty cycles
Better quality equipment — operators invest in energy-efficient, commercial-grade appliances that last longer

Reduced Food Waste

Communal cooking and shared meals naturally reduce food waste. When coliving residents cook together, they buy in bulk (reducing packaging), share ingredients (no more wilting herbs forgotten in the fridge), and consume meals collectively (fewer leftovers).

Brussels coliving residents report throwing away significantly less food than when they lived alone. Operators like Cohabs encourage communal cooking through their weekly dinner traditions, and some houses organize shared grocery runs.

Lower Transport Emissions

Coliving operators strategically locate properties near public transport, cycling infrastructure, and urban amenities. This means residents are less likely to own or need a car. Brussels' coliving spaces are concentrated in walkable neighborhoods like Ixelles, Saint-Gilles, Etterbeek, and the city center — areas where daily needs are met within a short walk or bike ride.

Several coliving operators actively support car-free living:

Bike storage is standard in most coliving properties
Some operators provide shared bikes or cargo bikes
Proximity to Villo! stations and public transport is a key factor in property selection

What Brussels Coliving Operators Are Doing

Energy Efficiency Investments

The best coliving operators are investing in energy efficiency:

Cohabs has been upgrading insulation and heating systems across their portfolio. Several properties now have A-rated EPC (Energy Performance Certificate) scores, which is impressive for Brussels' aging building stock.
Corners selects properties with good natural light and thermal performance, reducing the need for artificial lighting and excessive heating.
LiveColonies specializes in renovating historic buildings, bringing them up to modern energy standards while preserving architectural character.

Green Energy Procurement

Several operators have switched to 100% renewable electricity contracts. In Belgium, this is straightforward — providers like Eneco, Bolt, and Cociter offer green energy plans. The cost premium is minimal, but the impact on carbon footprint is significant.

Waste Reduction Programs

Brussels has a rigorous waste sorting system (PMD bags for packaging, green bags for food waste, white bags for general waste). Coliving operators facilitate compliance by:

Providing clearly labeled sorting stations in kitchens
Educating new residents (especially those from countries without similar systems) on Brussels' sorting rules
Some houses compost food waste in garden compost bins

Neybor has been particularly active in waste reduction, working with local zero-waste shops and encouraging residents to adopt reusable alternatives.

Water Conservation

Belgian water isn't scarce, but conservation still matters. Shared bathrooms and kitchens naturally use less water per person than individual setups. Some operators have installed low-flow showerheads and dual-flush toilets across their properties.

Brussels' Green Initiatives That Complement Coliving

Good Move Plan

Brussels' mobility plan, Good Move, is redesigning the city's streets to prioritize walking, cycling, and public transport over cars. New cycling infrastructure, expanded pedestrian zones, and traffic-calmed neighborhoods directly benefit coliving residents who typically don't own cars.

Low Emission Zone

Since 2018, Brussels has enforced a Low Emission Zone (LEZ) restricting older, more polluting vehicles from entering the city. By 2030, all diesel vehicles will be banned; by 2035, all combustion engines. This pushes the city toward cleaner air — a benefit everyone shares, but particularly those living in dense, central neighborhoods where coliving is concentrated.

Circular Economy Initiatives

Brussels has embraced circular economy principles through programs like BeCircular, supporting businesses that reduce waste and extend product lifecycles. Some coliving operators participate by:

Furnishing properties with refurbished or locally made furniture
Partnering with repair cafes for fixing broken items rather than replacing them
Donating items left behind by departing residents to local charities

Urban Farming and Community Gardens

Brussels has a growing network of community gardens (potagers collectifs). Some coliving properties with garden space have established their own mini-gardens where residents grow herbs, vegetables, and flowers. Cohabs and LiveColonies properties in Ixelles and Saint-Gilles have experimented with this, giving residents a connection to their food and outdoor space.

How to Live Sustainably in Brussels Coliving

Even within a coliving setup, individual choices matter. Here's how to maximize your positive impact:

Choose an Operator That Aligns With Your Values

Ask operators about their sustainability practices before signing. Questions to ask:

What's the property's EPC rating?
Do you use green energy?
How is waste sorting organized?
Are appliances energy-efficient?

Reduce Your Consumption

Shop at Brussels' local markets (Flagey, Marche du Midi) for seasonal, local produce
Use refill shops like The Barn (Ixelles) or Day by Day for packaging-free groceries
Borrow from housemates before buying new — coliving makes sharing easy

Embrace Brussels' Cycling Culture

Use Villo! or Billy Bike for short trips
Buy a second-hand bike for daily commuting
Take advantage of Brussels' expanding cycling network — the Villo! system now covers over 360 stations

Use Your Coliving Community

Sustainability is easier together. Organize with your housemates to:

Do shared grocery runs (fewer trips, bulk buying, less packaging)
Cook communal meals (less food waste, shared energy use)
Share subscriptions and resources (streaming services, tools, books)
Organize clothing swaps instead of buying new

Support Local and Sustainable Businesses

Brussels has a thriving sustainable business scene:

Flagey Bio Market — organic produce every Saturday
Paysan Urbain — urban farming cooperative
Brussels Beer Project — sustainable brewery with a focus on circular production
Les Petits Riens — second-hand shops supporting social causes

The Bigger Picture

Coliving alone won't solve the climate crisis. But as a housing model, it represents a meaningful shift toward more efficient, less wasteful urban living. In Brussels, where the building stock is old and energy-hungry, coliving operators are driving renovation and efficiency improvements that might otherwise take decades.

The math is straightforward: sharing resources means using fewer resources. Fewer square meters heated per person, fewer appliances manufactured, fewer car trips, less food wasted. Multiply these savings across the thousands of coliving residents in Brussels, and the impact is significant.

As Brussels pushes toward its 2030 climate targets, coliving isn't just a lifestyle choice — it's a practical contribution to a more sustainable city. And with operators like Cohabs, Corners, LiveColonies, Colive, Ikoab, Neybor, Habyt, and Morton Place continuously improving their environmental practices, the sector is only getting greener.

Choose coliving, and you're choosing a lighter footprint — without sacrificing comfort, community, or convenience.
