The "Guess the Cube" contest winner is Josh R. in Sacramento.
Josh won a home energy assessment valued at $500 from Brower Mechanical. He also received a fun pack of solar toys, sustainable houseware decorations, and three $25 gift cards for Subway, Peet's and iTunes. Enjoy!
Q: What is the 30-foot x 30-foot x 30-foot CUBE on K Street?
A: The cube represents 1 METRIC TON of carbon dioxide gas

Every year, each Sacramento resident generates 10 metric tons (or cubes) of carbon dioxide gas – that’s roughly 40 metric tons per four-person household.
Multiply that by the 450,000 people living in Sacramento, and we’re generating nearly 4.5 million tons of carbon dioxide gas.
Imagine, if our cubes were placed side by side, it would be enough to wrap around the entire planet! That’s a lot of greenhouse gas emissions—and although the gas is invisible, it makes a significant contribution to climate change.
TAKE ACTION: Cut Your Cubes
The cities of Sacramento, Davis and Citrus Heights are participating in the Cool California Challenge, a statewide initiative to reduce our collective carbon footprints.

Why a gigantic cube on K Street?
Who thinks of these crazy things?
Cut Your Cubes is an awareness campaign for the people living and working in Sacramento. Our goal is to get you to take action and reduce your carbon footprint by adopting simple behavior and lifestyle changes.
The City of Sacramento, Greenwise Joint Venture and 350 Sacramento -- along with a host of sponsors -- launched the campaign on June 25 by building a large, 30-foot-tall cube in downtown Sacramento.
The cube is a visual representation of one metric ton of carbon dioxide gas, if the invisible gas was confined in one space, and is a good way to visualize carbon dioxide.
