The Environment

Morsø gives you local warming. Not global warming.

A simple illustration showing the carbon cycle in terms of a house, a tree and CO2 circulation to show that Morsøs are the most efficient wood burning stoves around.Wood burning stoves raise the question of global warming: they emit carbon dioxide (CO2), so are they damaging to the environment? In fact, the most efficient wood burning stoves are just about carbon neutral. They are certainly more efficient than burning gas or coal.

As trees grow, they absorb and lock in CO2 as part of photosynthesis. When the trees are felled and burnt, they release it back into the atmosphere. When wood is burnt, more CO2 is released than if it simply rotted down (because of the work of bacteria and other micro-organisms). However, if wood is burnt efficiently, much less CO2 is emitted.

Unlike oil, coal or gas, wood can be replaced much more quickly by planting new trees. This helps to maintain the neutral carbon cycle, generation after generation.

Wood must burn as efficiently as possible to make wood burners truly carbon neutral. This is where Morsø really comes into its own: our constant research and innovation has led to our developing the most efficient wood burning stoves in the world.


On the one side, there’s talk about CO2 and global warming. On the other, there’s the recurring debate about soot, which, along with harmless water vapour, is contained in the smoke emitted from any wood-burning stove.

Being environmentally friendly isn’t just about reducing carbon dioxide emissions. There is an ongoing debate about soot which, together with water vapour, makes up the smoke emitted from any wood burning stove.

When we develop our wood burners, we always do so from an eco-friendly point of view.

Modern Morsø stoves, if used correctly, are among the most efficient wood burning stoves in the world. And we can prove it. We have demonstrably reduced the emission of particles to an absolute minimum using refined combustion technology and advanced purification systems.

We make a wide range of DEFRA-approved wood burning stoves for use in smoke-free zones. They adhere to the strict requirements of the Clean Air Act 1993.



Morsø’s wood-burning stoves meet some of the strictest environmental standards in the world. In particular, they meet Norwegian Standard NS 3058/3059, which sets out stringent requirements on minimising particle emissions.

Most Morsø wood burning stoves are certified by the Nordic Swan Eco-label. This not only highlights the stove’s minimal impact on the environment when operating, it also highlights the minimal environmental impact caused by the actual production and packaging too.

Our stoves are also tested for low particle emissions in the USA and Austria.

All our wood burning stoves comply with European Standard EN 13 240, which means that they are CE-marked.
