Reviesta Consulting Group develops next-generation Sustainable Smart City concepts that combine renewable energy, intelligent infrastructure, and global trade into one powerful economic ecosystem. Our vision goes beyond urban development — we create cities designed to attract international investors, global corporations, and innovative industries from day one.

Dipl.-Ing. Goekhan Yildirim, CEO of REVIESTA Consulting Group, is also President of the World Sustainable Energy Institute (WSEIN) in Vienna and an internationally recognized expert in Sustainable Smart Cities and Global Smart Trade. Through his work across Europe, the Middle East, and Asia, he facilitates high-level strategic cooperation between governments, investors, trade institutions, and multinational companies, helping to develop next-generation sustainable cities and global smart trade platforms.

Through the EU Trade Business Club, we introduce a new concept: Smart Trade within Smart Cities. A city of the future must not only be sustainable — it must also be economically powerful. Our model integrates renewable energy, digital infrastructure, logistics systems, and international trade into one connected platform that creates long-term economic value.

The Vision

To develop self-sustaining cities that generate their own energy, reduce operational costs, attract international investment, and become regional economic hubs. The new Sustainable Smart City is not only a place to live — it is a platform for innovation, technology, and global business.

Why Investors Are Interested

• A new city designed specifically to attract international capital
• Strong long-term return potential through sustainable infrastructure
• Integration of renewable energy and smart mobility systems
• Global trade and logistics connectivity (sea, road, rail, and air)
• High demand for sustainable cities and smart infrastructure worldwide
• Strategic cooperation with governments, corporations, and global partners

The Concept: A Self-Sustaining City

The city will use renewable energy systems, intelligent mobility solutions, smart logistics, and modern digital infrastructure to create a sustainable and economically strong urban environment. At the same time, we aim to transform existing cities into self-sustaining smart cities through innovative planning and modern regulations.

Inspired by the World’s Leading Cities
Our concept combines the strongest elements of Barcelona (smart innovation), Copenhagen (carbon neutrality), London (intelligent mobility), Tokyo (smart urban development), Paris (sustainable transport), Hong Kong (digital systems), Toronto (smart commuting), and Vienna (one of the world’s leading smart and sustainable cities).

Our Goal

A new Sustainable Smart City in one country — and a new Sustainable Smart City model for the world.
