Eco-friendly paints and low VOC emissions: choosing for a healthier interior

When you renovate an apartment in Paris or a house in Lyon, paint selection goes beyond colours and finishes. Eco-friendly and responsible paints are experiencing strong growth in 2026, driven by the search for more environmentally respectful solutions1. For many homeowners in Île-de-France, Provence or Brittany, choosing a paint with low VOC (volatile organic compounds) emissions has become a reflex to guarantee healthier indoor air.

What is an eco-friendly paint with low VOC emissions

An eco-friendly paint stands out through its composition. Natural paints replace petrochemical binders with vegetable oils (linseed, sunflower, safflower), natural resins and mineral or plant-based pigments. This substitution makes it possible to drastically reduce emissions of volatile organic compounds, those chemical substances that evaporate into the surrounding air for months or even years after application.

VOCs are present in traditional petrochemical solvent-based paints and can cause headaches, respiratory irritation and allergies. Eco-friendly paints are not completely free of VOCs, but their rate is limited to 5 g/l, sometimes less, compared to up to 30 g/l permitted for conventional paint. For children's bedrooms in Toulouse or living spaces in Nantes, this difference can genuinely improve the quality of the air breathed daily.

Official labels to identify genuine eco-friendly paint

Faced with the proliferation of marketing claims ("natural", "bio", "eco"), official labels remain the only reliable reference point. In France, two certifications dominate the market: the European Ecolabel and the NF Environment label, both issued by AFNOR.

The European Ecolabel is more demanding on certain criteria: the maximum VOC content is 15 g/L compared to 30 g/L for NF Environment. On the other hand, NF Environment examines a wider range of criteria, including the absence of nanomaterials. Both labels guarantee that the product complies with strict standards throughout its life cycle, from manufacturing to waste disposal.

For a renovation project in Bordeaux or Strasbourg, systematically choose paints bearing one or the other of these labels. They certify that the product has been checked by an independent body and meets verifiable environmental requirements. The A+ labels (very low VOC emissions) mandatory since 2012 also constitute a good indicator, but they remain less selective than official labels.

Bio-based paints: the plant-based alternative for your walls

Bio-based paints represent a specific category of eco-friendly paints. The bio-based designation refers to eco-friendly paints based on vegetable resin and natural components (95% or more). Pine resins, linseed oils, citrus extracts, Breton algae: these renewable raw materials replace ingredients derived from petrochemistry.

On the French market, several brands offer accessible bio-based ranges. Unikalo Naturéo offers a bio-based range based on vegetable resins with more accessible pricing and guarantees national manufacturing with NF Environment labelling. These paints are perfectly suited for large renovation projects in Marseille, Nice or Rennes, where the performance to price ratio matters as much as environmental requirements.

Bio-based paints offer coverage power comparable to conventional acrylic paints, with quick drying and little odour. They apply to walls and ceilings in all rooms, including humid spaces like bathrooms, provided you choose an appropriate finish. For a bedroom in Lille or a lounge in Normandy, they represent a coherent choice between reduced environmental impact and technical performance.

Practical criteria for choosing your eco-friendly paint

Beyond labels, several practical criteria will help you select the eco-friendly paint best suited to your project.

Start by checking the actual composition of the product. Technical data sheets must clearly state VOC content and the percentage of bio-based ingredients. For truly healthy paint, aim for less than 1 g/L of VOC, especially for children's bedrooms or enclosed spaces.

Next, adapt the type of paint to the room. Mineral paints based on lime or silicate are particularly suitable for old stone walls in Brittany or Alsace, as they allow supports to breathe. Bio-based acrylic paints apply easily to plaster and plasterboard in Haussmann-style apartments in Paris or recent constructions in Toulouse.

Finally, prepare your surfaces properly before application. Even an eco-friendly paint requires a clean, dry and degreased support to adhere durably. Use an appropriate primer if you are covering a dark colour or a stained wall. Ventilate the room well during and after work, even if VOC emissions remain low: aeration accelerates drying and removes residual odours.

On our platform, all professionals who work are verified: we confirm they are properly registered as self-employed or have a company in proper standing. You can request detailed quotes from them after sharing photos and videos of your walls, which allows you to get a precise estimate without waiting for an on-site visit. The project details, once validated, remain visible online for you, the painter and the platform, ensuring total transparency on the agreed scope. Payment is made in two instalments: 50% at the start to reserve the date and purchase materials, then 50% at the end, once the work has been verified.

Choosing an eco-friendly paint with low VOC emissions for your interior in Lyon, Paris, Marseille or elsewhere in France is investing in healthier air and a preserved environment, without sacrificing the quality or durability of the result.
