Research shows that the physical and social environments we live in have a major influence on our health and well-being. As we spend of our time spent indoors the material health of the products and flooring in our homes and workplaces play crucial roles.

 ![Office space with hanging plants](https://europeblog.milliken.com/hs-fs/hubfs/Blog%20Images/Benefits%20of%20low%20VOC%20flooring/Nat%20West%20-%20Break%20Out%20LVT%20copy.jpg?width=722&height=456&name=Nat%20West%20-%20Break%20Out%20LVT%20copy.jpg)

Choosing products with low or no VOC emissions is, therefore, instrumental to prevent adverse impact on indoor air quality. To learn more about what VOCs are and where they come from click here.

## How do we assess which products have lowest VOCs?

 Most reputable manufacturers test and disclose the emissions of their interior products and flooring. In fact, in France it’s a legal requirement for all (non-inert) interiors products to have an emissions label. While CE marking of Flooring currently only requires declaration of the level of one specific VOC - Formaldehyde. However, there are proposals to include total VOC content in the future.

There is however a wide range of VOC Certifications, and technical specification sheets may state compliance with various low-emission VOC test standards including, California’s[CDPH](https://www.cdph.ca.gov/), Germany’s [AgBB](https://www.umweltbundesamt.de/en/topics/health/commissions-working-groups/committee-for-health-related-evaluation-of-building) or European Union’s [LCI emission standards](https://single-market-economy.ec.europa.eu/sectors/construction/eu-lci-subgroup/about_en), so it is helpful to know how these compare.

## How To Understand Low VOC Flooring Certifications

These are the most common VOC certificates and associated tests for assessing VOC emissions of Flooring.

![Low VOC flooring certification logos](https://europeblog.milliken.com/hs-fs/hubfs/Blog%20Images/VOC%20certifications/Low-VOC-Blog-LOGOS-1%20copy.jpg?width=722&height=111&name=Low-VOC-Blog-LOGOS-1%20copy.jpg)

![Table showing low VOC certifications, test methods andTVOC limits](https://europeblog.milliken.com/hs-fs/hubfs/Blog%20Images/VOC%20certifications/Low-VOC-Blog-TABLE1%20copy.jpg?width=722&height=238&name=Low-VOC-Blog-TABLE1%20copy.jpg)

In addition to meeting the criteria for Total VOCs these test certification standards also have limits for specific individual VOCs for some of the more harmful chemicals such as Formaldehyde, or other known carcinogens.

All of the certifications meet the CDPH standards although only [CRI Green Label Plus](https://carpet-rug.org/testing/green-label-plus/), [Indoor Advantage Gold](https://www.scsglobalservices.com/services/indoor-air-quality-certification) and [FloorScore](https://www.scsglobalservices.com/services/floorscore) use the CDPH's standard method. Only [GUT](https://gut-prodis.eu/en/gut-label/), [TUV Proficert Premium](https://www.proficert.de/en/) and [Indoor Air Comfort Gold](https://www.eurofins.com/consumer-product-testing/industries/construction-building/indoor-air-comfort/indoor-air-comfort-certification/) comply with the stricter standards set by the AgBB and European Unions LCI.

## How To Minimize VOC Emissions from Wet Finishes?

It’s also important to consider how the flooring will be installed, will adhesives and sealants be used in the process? Most liquid interiors products will state the level of VOC as part of their content label. However, this is different to the amount of VOC that will be emitted and at what rate. Looking for products with [GEV Emicode](https://www.emicode.com/en/home/) label ensures full product transparency of VOC content and off-gassing rate.

![EMICODE Labels ](https://europeblog.milliken.com/hs-fs/hubfs/Blog%20Images/VOC%20certifications/EMICODE%20Labels%20on%20their%20own%20copy.jpg?width=722&height=173&name=EMICODE%20Labels%20on%20their%20own%20copy.jpg)

The premium class EMICODE EC1 Plus defines the limit of what is technically feasible today. Introduced in 2010, it sets even higher and stricter limit values than category EC1.

The highest class EMICODE EC1 has proven itself over many years as a standard for products that are very low in VOC emissions. The materials awarded this label comply with very stringent health and environmental requirements.

Low emission products are awarded the EMICODE EC2 label. This class fulfils the basic requirements for being granted the EMICODE label.

The Total Volatile Organic Compounds (TVOC) and Total Semi-Volatile Organic Compounds (TSVOC) emissions limits for each EMICODE® class are shown in the tables below.

## Which Flooring “Green Labels” do these tests Support?

These tests form the basis of the emissions compliance element of a wide number of Eco labels

[**BREEAM**](https://breeam.com/standards) recognizes the importance of Indoor Air Quality. *Credit* [*HEA 02: Indoor air quality*](https://kb.breeam.com/wp-content/plugins/breeamkb-pdf/pdf/?c=97)includes a number of approaches to manage harmful emissions. Up to 2 credits can be achieved for the specification of construction products and finishes that are certified as Low VOC. This includes floorings certified to GUT, Indoor Air Comfort Gold, TUV Proficert Premium, Floorscore, and wet finishes with EC1 Emicode label

[**LEED**](https://www.usgbc.org/leed)provides up to 4 credit for [Low Emitting Materials](https://www.usgbc.org/credits/commercial-interiors/v5/mrc3?return=/credits/Commercial%20Interiors/v5/Material%20&%20resources) within [Materials and Resources](https://www.usgbc.org/credits?Category=%22Material+%26+resources%22&Rating+System=%22Commercial+Interiors%22). To ensure flooring qualifies products must meet LEED's "Low-emitting Criteria” or be inherently non-emitting, salvaged or re-used. To meet the low-emitting criteria products require certification testing in line with either the CDHP California standard or more stringent European tests such as IAC Gold / TUV Proficert Premium. Wet applied adhesives must also be compliant. LEED awards additional credits for [Air Quality Testing and Monitoring](https://www.usgbc.org/credits/commercial-interiors/v5/eqc5?return=/credits/Commercial%20Interiors/v5/Indoor%20environmental%20quality)within<https://www.usgbc.org/credits/commercial-interiors/v5/eqc5?return=/credits/Commercial%20Interiors/v5/Indoor%20environmental%20quality>[Indoor Environmental Quality](https://www.usgbc.org/credits?Category=%22Indoor+environmental+quality%22&Rating+System=%22Commercial+Interiors%22). 1 credit is provided for testing the total VOC emissions.

[**WELL**](https://www.wellcertified.com/)recognizes the importance of Indoor Air quality and on-site testing to strict air quality levels including VOC limits is one of the Pre Conditions of the [Air concept](https://v2.wellcertified.com/en/wellv2/air). In addition, specific optimisation credits are available within the Materials Concept [X06.2](https://v2.wellcertified.com/en/wellv2/materials/feature/6?part=2) for selecting low VOC emitting furniture, architectural and interiors products (including flooring) & [X06.1](https://v2.wellcertified.com/en/wellv2/materials/feature/6?part=1) for limiting VOCs associated with wet applied products including flooring adhesives**.**

## How Can You Ensure your flooring meets the best standards?

Carpets showing the [GUT label](https://gut-prodis.eu/en/gut-label/) and installation products with an [EMICODE® EC1PLUS label](https://www.emicode.com/en/emission-classes/) meet the tightest standards in the flooring industry. Floorings tested to either [TUV Premium](https://www.proficert.de/en/) standard or [Eurofins IAC Gold](https://www.eurofins.com/consumer-product-testing/industries/construction-building/indoor-air-comfort/indoor-air-comfort-certification/) and installation materials with an [EMICODE® EC1 label](https://www.emicode.com/en/emission-classes/) meet the low VOC emissions standards, required for compliance to many other labels and the major Green Building standards such as [**WELL**](https://www.wellcertified.com/), [**LEED**](https://www.usgbc.org/leed), [**BREEAM**](https://breeam.com/standards). So be sure your flooring and installation materials meet at least one of these certifications.
