Eco Tycoon: Project Green

Eco Tycoon: Project Green is a business simulation game in which players have to manage various environmental concerns while maintaining the country's economy. On starting playing a new game, the players begin their journey in the year 2010, and have a limited 50 years to reduce their carbon dioxide emissions as agreed upon at "World Summits", which take place every five years beginning in 2015. The "world summit" is an in-game organisation that determines how aid is distributed to promote emission reductions. The player starts with a small region containing only cities in which he constructs such buildings as mines, power plants, and businesses. There is a finite number of locations in which buildings can be placed, requiring careful planning. Along with reducing emissions, the player must also balance the production and consumption of electricity, water, food and garbage while sustaining the economy.

There are seven playable regions in-game: North America, South America, Europe, Africa, North Asia, South Asia and Australasia. Every region has different environmental balance, different resource availability and population. For a single-player game the player chooses a region and the rest are controlled by computer, or the AI. There is no rivalry among the different regions, indeed they are friendly and money and resources can be traded with each other.
