Which city was envisioned to be the first intelligent and ecological city in the Philippines?

The city envisioned to be the first intelligent and ecological city in the Philippines is Bonifacio Global City. This development is notable for incorporating sustainable practices, smart urban planning, and advanced technology in its design and functionality. Bonifacio Global City, located in Taguig, has been designed with an emphasis on creating a vibrant, livable urban environment that promotes eco-friendliness and the efficient use of resources.

It features a walkable layout, green spaces, and modern infrastructure that supports its commitment to sustainability. The integration of digital technology in urban services and management contributes to its 'intelligent city' concept. This sets it apart from the other options, which, while significant in their own right, do not share the same level of commitment to being recognized specifically as ecological and intelligent urban developments.
