The EU Needs Innovations That Drive Climate Neutrality

As a result of human activity, the increasing concentration of carbon dioxide in the atmosphere is considered one of the greatest future risks, as scientific models indicate it raises atmospheric temperatures and thereby causes major changes around the world. For this reason, for example, the European Parliament has approved a climate law that raises the EU’s 2030 emissions reduction target from the previous 40% to 55%, and makes climate neutrality by 2050 a legally binding objective.

To achieve this goal, we can either return to the Stone Age or develop new technology. Finnish company Elementic has chosen the latter and is currently building a pilot plant based on its own innovation. In practice, this means producing a construction material similar to bricks, using lignin — the natural binder found in wood — as the key ingredient.

Since lignin makes up about one-third of wood, this would significantly increase the value of forests and allow the forest-based industry to grow without compromising the production of its current products. As an added bonus, carbon dioxide emissions from construction would disappear, as a house built from lignin bricks would store more carbon than is emitted during its construction.

To top it off, there are two more noteworthy advantages. First, production can be scaled up quickly by modernizing existing brick factories in Finland and elsewhere in Europe — there’s no need to build new production facilities for lignin bricks. Second, lignin as a building material is non-flammable, weather-resistant, and rot-proof.

It remains to be seen whether the Finnish company will succeed in selling its new product to construction firms — and whether, as a result, the EU’s goal of climate neutrality might be achieved much more easily than it seemed not long ago. In any case, it is already clear that the EU needs more innovations like the one described above to drive progress toward climate neutrality.

Medieval trade ranged from North America to Ukraine

We all know that the Vikings were the first Europeans to land in North America. In addition, they had settlements in Greenland where no trees grow. Therefore, the Norse people, who lived in Greenland from AD 985 to 1450, relied on imports, mostly from Northern Europe, for various materials, including iron. 

Now a new investigation of ancient pieces of wood has revealed that at least 26 out of over 8 500 wood remnants found in five Norse sites in western Greenland came from trees that could not have reached Greenland solely through the natural action of tides and waves. The researchers from the University of Iceland examined the microscopic structure of the 800 years old wood remnants and concluded that the imported timber, which included species like hemlock and Jack pine, originated from mainland North America.

This discovery challenges the previous belief that Norse people exclusively imported materials from northern Europe. It suggests that they were, in fact, importing materials from the northeastern coast of mainland North America for a longer duration than previously assumed. 

Furthermore, it indicates that the Norse people had established trade connections and actively imported resources not only from distant locations within Europe but also maintained long-distance connections extending to the west. As a result, their international trade network spanned from what is now Ukraine to North America.
