As the world moves toward greener initiatives, construction companies are embracing sustainability like never before. The construction sector has traditionally been resource-intensive, with significant environmental impacts. However, increasing demands for energy efficiency, reduced waste, and carbon neutrality are reshaping the industry, pushing companies to adopt technologies and methods that align with long-term sustainability goals. Firms like Skanska and Laing O’Rourke are leading the way with innovative techniques and eco-conscious practices that set a benchmark for the industry.
The rise of green building
The construction industry has long been criticized for wasteful practices and high carbon emissions, but things are taking a turn. More companies are now integrating renewable energy, energy-efficient designs, and green materials. Governments and private organizations are setting stricter standards, promoting the adoption of low-carbon building techniques and advanced waste management systems. Technology like Building Information Modeling (BIM) and 3D printing enables companies to optimize resources and reduce waste. As a result, sustainability is becoming a central focus for large-scale projects and smaller developments. This shift meets global environmental goals and addresses consumer demand for greener infrastructure.

When I look at the list of global leaders in sustainable construction, I am glad to see the industry moving toward eco-friendliness and innovation. However, it is important to understand that the future of sustainable construction is shaped not only by giants with billion-dollar budgets, but also by mid-sized companies that work closer to people, their daily needs, and local resources.
KOLEO was born in the Carpathians, where wood is not just a building material but a part of the cultural code. We build homes that breathe, retain warmth in winter and coolness in summer, while placing minimal strain on nature. Our approach is a blend of tradition and advanced technologies: from glulam and profiled timber to CLT panels and energy-efficient solutions.
For me, sustainable construction is not a trend, but a responsibility. A responsibility to the people who will live in these homes, and to nature, which provides us with the material. KOLEO is already implementing projects in Ukraine and beyond, and we are confident that our experience can become part of the global movement for ecological architecture.
The world does not only need ‘green skyscrapers’ but also accessible, high-quality, eco-friendly housing for families. This is where, I believe, companies like KOLEO make their contribution to the real future of sustainable construction.
