Sustainability Is Part of Our DNA



Our Guiding Principles
Quality Education
SDG 4We believe that forward-thinking engineering starts with continuous learning. That’s why we invest in education and knowledge transfer—enabling our teams to push boundaries and drive sustainable progress alongside our clients and partners.
Affordable and Clean Energy
SDG 7Through our commitment to the offshore wind sector, we advance the use of renewable energy sources. Our goal is to promote access to clean and affordable energy, contributing to the global reduction of CO₂ emissions.
Industry, Innovation, and Infrastructure
SDG 9Strong, resilient communities depend on cutting-edge solutions for sustainable building and energy management. We are committed to projects that not only enhance infrastructure but also promote best practices in environmental protection and sustainable resource use.
Responsible Consumption and Production
SDG 12In both our projects and internal operations, we prioritize resource-efficient processes, favor sustainable materials, and minimize waste, supporting a circular economy and extending the lifespan of the buildings and structures we plan.
Climate Action
SDG 13Every construction project we undertake has the potential to make a difference. We help our clients realize this potential through high-quality work, technical excellence, sustainable design concepts, and environmental impact assessments—because effective climate action starts today, for a better tomorrow.

Certified Sustainability—Independently Verified
Transparency is essential to recognize weaknesses and drive meaningful improvements. That's why our environmental management system is ISO 14001 certified, ensuring consistent oversight and accountability throughout the entire organization.


Everyday Sustainability
Whether it’s leasing e-bikes, going paperless, or switching to electric vehicles—sustainability is woven into our everyday life at JBO. Every team member helps shape this culture and is invited to share ideas that drive change.

Investing in Local Ecosystems
As climate change threatens local ecosystems, biodiversity continues to decline. That’s why we support targeted nature initiatives like the restoration of traditional orchard meadows: richly biodiverse habitats where fruit trees grow among flowering grasslands. These landscapes provide vital space for pollinators and wildlife while helping reduce CO₂.
