Here's your chance not just to be the mayor, but the original city planner as well! Imagine a medium sized city that would be developed with modern, low carbon transportation in mind, and other strategies to reduce the average citizens' carbon footprints.
What would that city look like? Would that make you more likely to want to live there?

Sustainable Materials
Would using sustainable materials like hempcrete and cork to build houses reduce carbon footprint?
Sadly, sustainable housing is expensive so not a lot of ppl wanna build them... 
I think hempcrete would help since it looks pretty eco-friendly. "Lasts 100's of Years" and "Energy Efficient" definitely be a lot of help. Could you use the cork to make bottles instead of plastic bottles though? Maybe that would help...
I definitely agree with using sustainable materials.
But, a cheaper version you could use wood. But, in Japan people cut down old trees, since they absorb less CO2, and if they stay there it is not good for the environment. But remmeber to plant a tree back!
Using the wood of trees would be much cheaper but the tree would take half a century to fully grow. Yess, planting a tree would be a good idea but they could be overused and it’d take a lot of time for them to grow.
me to
isn't hemp a drug?
nevermind its marijuana
Using bamboo could be a great replacement for trees. It takes less than half the time to grow, and less animals use bamboo forests as a habitat compared to the vast amount of ecosystems destroyed when cutting down a forest.
And to answer your question about cork, cork is a very cheap and energy efficient material for used for building. (and wine stoppers) People can build with large blocks of compacted cork.
Here, I attached a picture of a house made mostly of straw and cork.
yeah but its made for building not a drug!!! 
im bamboo
bamboo is a very efficient building material.
im not sure if hemp is a drug but hempCRETE is basically concrete but more energy efficient.
