In a world where both environmental concerns and global mobility are rising priorities, more individuals are seeking not just a second passport—but a second home that aligns with their values. Clean air, sustainable living, and a high quality of life have become decisive factors in choosing where to live. For many, the answer lies in the unlikeliest of connections: their own ancestry. The cleanest countries citizenship by descent offers a legal and often low-cost pathway to living in countries known for their environmental leadership.
As more people research where they might legally belong, an interesting trend emerges. Countries that top the list for citizenship by descent are often also ranked among the cleanest countries in the world. From pristine landscapes in Finland to the well-managed urban environments of Switzerland, these nations offer more than heritage—they offer a greener future.
What Is Citizenship by Descent?
Citizenship by descent, also known as jus sanguinis (“right of blood”), allows individuals to obtain nationality based on their parents’, grandparents’, or sometimes great-grandparents’ citizenship. Unlike naturalization, which often requires long-term residency, or investment programs that involve significant financial contributions, descent-based citizenship is rooted in legal heritage.
Many European countries offer this opportunity. Ireland, for example, allows individuals with Irish-born grandparents to apply. Italy goes even further, allowing those with an unbroken male bloodline (and in some cases maternal lineage) to reclaim their Italian citizenship. Finland, Poland, and even New Zealand also offer varying pathways to reconnect with your heritage legally and permanently.
Defining “Cleanest Countries” and Why It Matters
Cleanliness in a national context isn’t just about litter-free streets. It’s a multi-dimensional measure that includes air and water quality, public health standards, waste management efficiency, renewable energy use, and green infrastructure. The Environmental Performance Index (EPI), developed by Yale and Columbia Universities in partnership with the World Economic Forum, ranks countries based on these key metrics.
Why does this matter for citizenship? Because living in a clean country directly impacts quality of life. Clean air reduces respiratory issues. Clean water prevents disease. And well-regulated urban areas reduce environmental stress. For individuals who gain citizenship by descent, it’s not just about a legal status—it’s about gaining access to a healthier, more sustainable lifestyle.
