Silicon Valley is known for both innovation and hype. Recently, this pool of innovation has extended beyond bandwidth to the protection the environment. Google and Yahoo, the search engine giants, are both headquartered in the Valley and have been making headlines by greening their offices, reducing energy consumption, and carbon trading. The PR motivations are obvious, but are the green benefits really there? To set apart the hype from reality, we have analyzed the green value of both Google and Yahoo's headquarter facilities.
We looked at the ecological services provided by green landscape features such as trees and open space (i.e. grass). Grass and trees are pervious surfaces, meaning they allow water to permeate into the ground. Roofs, sidewalks, patios, and asphalt parking lots are examples of impervious surfaces, where rainwater drains into the public storm drains. Heavy metals, oil, and other pollutants are carried off parking lots in rainwater, which often lead directly to open water habitats, where fish, birds, and reptiles live.
In terms of ecological services, trees and grass have been proven to:
1. Remove and store carbon from the atmosphere,
2. Remove certain airborne pollutants,
3. Permits rainwater to seep into the ground as opposed to draining into the stormdrains, and
4. Remove certain waterborne pollutants.
Here is a look at how green Google and Yahoo really are and how the measure up against each other.
Google Green Report
Google's headquarters, the Googleplex, covers 44 acres, nearly 50% of which is grass or tree canopy. This is an impressive paved to open space ratio. The grass and trees on the Googleplex remove roughly 2 tons of carbon from the atmosphere per year, or 0.04 tons per year per acre. In addition, 530 lbs. of air pollution are removed per year (e.g., ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter), or 12 lbs. per year per acre. It was assumed that the parking lot of the Googleplex is asphalt, and not a type of porous pavement, so the cost of managing rainfall runoff from the Googleplex is $4,474 per year, or $103 per year per acre. The abundance of grass and tree canopy on the Googleplex go a long way to offset the water quality impacts of the paved surfaces (mainly the parking lot). On average, the grass and trees reduce water pollution by 6%, as opposed to the entire property being paved.
Yahoo Green Report
The Yahoo headquarters, Yahooplex, covers 28 acres, a third of which is grass or tree canopy. This is a classic ratio of paved to open space for large office complexes in California. So far, par for the course. The Yahooplex removes 0.36 tons of carbon from the atmosphere per year, or 0.01 tons per year per acre. 114 lbs. of air pollutants are removed per year, or 4 lbs. per year per acre. In terms of rainfall, the cost associated with runoff is $9,219 per year, or $331 per year per acre. The grass and tree canopy help offset the paved areas with a 2.3% reduction in water pollution as opposed to the entire property being paved.

Re: Google Vs Yahoo - Who's Greener?
Google has implemented various innovations in the online advertising market that helped make them one of the biggest brokers in the market. Using technology from the company Double Click, Google can determine user interests and target advertisements so they are relevant to their context and the user that is viewing them.

Hello Friends,
Silicon Valley is known for both innovation and hype. Recently, this pool of innovation has extended beyond bandwidth to the protection the environment.

The PR motivations are obvious, but are the green benefits really there? To set apart the hype from reality, we have analyzed the green value of both Google and Yahoo’s headquarter facilities.

It is hard to tell on choosing which is Greener among the two search engines since these two made their internet marketing strategy accessible to all online marketers out there.

Re: Google Vs Yahoo - Who's Greener?
Google kicks a*s of Yahoo, largely due to the foresight, or luxury, the Googleplex that 50% of its surface property green services. The good news for Google and Yahoo is that over time, as the trees grow, so will the tree and ground, thus storing more carbon and elimination of several air pollutants.

Google and Yahoo, both are the best search engine, Google is the first primary because it is too fast and give the result within a few seconds, Google is the first in the race with Yahoo and day-to-date daily Google user increasing and that popularity is too much for their source.

Re: Google Vs Yahoo - Who's Greener?
I like both. Definitely Google provide more information and it has large source of information, so many services. But Yahoo also good service provider. As far as concern about it's greenness, Yahoo is more greener than because large traffic of Google, they produced lots of trash.

Google is the favorite search engine as it gives you instant and accurate result in shorter period of time.
