9 Steps Cities Must Take to Dramatically Cut Carbon Emissions

9 Steps Cities Must Take to Dramatically Cut Carbon Emissions | Urbanisme | Scoop.it

A very long, very bold to-do list for the next 20 years.

The city of Toronto has already begun to sketch out policies that could reduce the area’s greenhouse gas emissions in the coming decades. Officials have proposed greening the electric grid, banning incandescent light bulbs, promoting green roofs on commercial buildings, retrofitting 1960s-era high-rises and implementing a stricter energy-efficient building code for new construction. With transportation, the city wants to expand bike lanes and transit infrastructure, all while it anticipates that electric vehicles will grow slowly more common.

This is a pretty standard menu of ideas, and according to scientists it will get the city part of the way toward the kind of changes broadly needed to really keep global temperature rise below 2 degrees Celsius.

But to really alter the future prospects for climate change, much more will have to happen in Toronto, and every other city. Researchers used the city as a case study to model what a truly aggressive framework might look like. If Toronto wants to cut emissions by 70 percent by 2031, all of these actions (or others with a similar impact) might be required in tandem...

While the steps being proposed in Toronto may not be as aggressive as those recommending by researchers concerned with reversing the climate changes caused by humanity's activity, they are at least a step in the right direction and far more than what seems likely in most U.S. cities.

CO2ngress Towers: Reducing air pollution in Chicago + increasing public awareness

CO2ngress Towers:  Reducing air pollution in Chicago + increasing public awareness | Urbanisme | Scoop.it

““Every day, 77,000 carbon-emitting vehicles fly past the Congress Parkway interchange, polluting the air. This project creates a gateway over the corridor that filters air and fuels a new breed of car for its residents.”

In attempt to cut down on Chicago’s CO2 emissions produced from cars in the Eisenhower Expressway, Danny Mui & Benjamin Sahagun propose the splitting of the Congress Gateway Towers, using a system of carbon scrubbers and filtration devices that clean carbon dioxide and other air pollutants. Aimed to increase public awareness and improve of Chicago’s public health, the CO2ngress Gateway Towers absorb the CO2 emissions from passing cars and is then fed to algae grown in the building. The algae then helps with the processing of biofuels which will supply the building residents’ eco-friendly cars.

I thought that this article was really cool that Chicago was going to build these towers as the gateway to this city. At the same time, I thought it was cool that it acts as a CO2 remover. It sucks up the carbon dioxide from the vehicles of the city and gets rid of it. I think it would be great if other cities could do this also to reduce the pollution.

After reading this article I thought it was really cool that Chicago is trying to make a difference. I didn't know that a simple building could make should a huge difference. This article is very interesting!

This is important for people to know just encase they go to the same place as it is happening.
