Today’s Solutions: December 17, 2025

More and more cities and countries are pledging to achieve net-zero emissions, but this task isn’t as easy as it seems. Some strategies, like installing renewable energy sources and electrifying public transport, are intuitive, but what about private households and emissions from landfills?

As mayor of Smogtown, the game tasks you with getting your city to zero emissions with challenging questions like whether you should try to make public transportation free or more efficient, and whether you should focus on building updates or planting more trees.
