Documented climate friendly with EPDs – what does this mean?

What do good food and sustainable materials have in common? In both cases, it’s better for the climate that we choose natural local products that have been processed as little as possible.

For many of us, when we’re about to enjoy a good meal, we like to know the origin of the ingredients used and to be able to rely on good, locally sourced products.

Just as you may be concerned about whether your meal is healthy and natural, you should ask the same important questions about the raw materials used for your cabin, house or garden. 

  • Are they natural materials?
  • Are they locally sourced?
  • Are they durable?
  • Can they be recirculated or recycled?

Look for products with an approved environmental declaration

These questions are a good start. But getting good answers can be both difficult and confusing. The trend is to market products as sustainable, even if this cannot be documented by a neutral professional body.

So a good tip is to look for products with an approved Environmental Product Declaration (EPD) that can document the impact of the manufacture, processing and use of the product on nature and the environment.

An EPD is an internationally recognised, neutral environmental declaration that documents and quantifies a product’s carbon footprint throughout its life cycle, from manufacture to disposal. This makes it possible to compare different products and materials and to choose a product that has less impact on the environment. 

With an EPD we can document what we’ve always known, which is that real Scandinavian slate from Oppdal, Otta and Offerdal shows very positive environmental performance throughout its lifetime. This is all covered by an international standard which clearly shows that our slate scores very high compared to other products and materials.

This makes it easier for you to make good, green choices.

So, in answer to your questions:

Is it a natural material?

Yes.

Real Scandinavian slate is exclusively produced by nature itself over several hundred million years.

Much of the processing of the finished product is done by hand, which means very low use of resources compared to factory-produced materials.

Is it locally sourced?

Yes.

We extract, process and transport slate exclusively from Oppdal and Otta in Norway, and Offerdal in Sweden.

This avoids long transport cycles that expose the climate to high CO2 emissions.

Is it durable?

Yes.

Real Scandinavian slate requires minimal maintenance and can last forever.

This means that over time, there will be no need for frequent improvements or replacements, which can be very resource-intensive and unsustainable.

Can it be reused or recycled?

Yes.

You never really need to get rid of real Sandinavian slate, but if you do feel like a change, it can be recycled and reused time after time.

Slate can be shaped, moved or sold online to new owners. It’s your decision!
