This weekend’s series against the Cubs marks the 4th year the Diamondbacks have held their "Green Series" – partnering with APS to promote energy efficiency. In addition to this annual educational awareness program, the Diamondbacks have implemented dozens of energy efficiency and environmental stewardship programs, including:

• The new APS Solar Pavilion which shades and cools the main entrance gate while generating solar energy
• Providing Recycling Bins for plastic and aluminum bottles around the ballpark
• Composting food and paper waste, recycling concession "grease" into biodiesel fuel
• Installing waterless urinals and hand dryers in bathrooms
• Closing the roof earlier in the day to save on air-conditioning
• Using Recycled Paper and Soy Ink for most marketing materials, distributing media guides electronically to save on paper
• Encouraging employees to take public transit and providing them with reusable beverage containers. Providing vendors with shirts made from recycled plastic bottles.
• During last year’s All-Star Game, Green Team members roamed the stands, collecting bottles and cans from fans.
• Season ticket holders are provided reusable "loyalty cups" for refills on soda
• LED equipment was installed throughout ballpark (including the scoreboard displays ) to save on energy (compared to older display equipment).
• I remember seeing electric car chargers at the 7th Street Bridge parking lot.. I am not sure if they are still there, or who gets to use them.

That’s quite a long list, and shows some real initiative from the Dbacks organization. But I am left wondering, what else within reason (and shy of turning OFF the air conditioning system) could the team do to reduce their carbon footprint and environmental impact?

We are off to tonight's game, taking the Metro Light Rail, of course.
