  • Regional Grid Greenhouse Gases: How much greenhouse gas does this facility’s local electrical grid emit while generating electricity? (Useful for Location-based greenhouse gas reporting)
Greenhouse Gases 2004 2008 2014 2018
MTCO2/MWh 0.599 0.494 0.446 0.374

The carbon-intensity of Germany’s grid has improved about 2.5% points per year over the last 14 years of published data. (2004-1014 data from European Environment Agency, 2018 data from “The European Power Sector in 2018“)

  • Regional Grid Renewables: What percentage of this facility’s local electrical grid is from renewable sources (wind, solar, biomass, hydro, and geothermal)?
Grid Renewables 2004 2008 2012 2016
Percent from renewable sources 5.5% 11.9% 19.3% 24.7%

This has been increasing about 1.6% points per year over the last 12 years of published data. (Data from the European Environment Agency.)

  • Other Features: Ultra-low PUE through the use of Indirect Adiabatic Air Cooling to each data hall


Dublin Onsite Wildlife Habitat

As part of planning our Dublin campus we developed a comprehensive ecology assessment. Based on this guidance, our landscapers planted native tree species, including a large selection of specimen trees complimentary to the local environment. Our full landscaping design focused on creating areas of grassland, wildflower meadows, and pollinator-friendly wetlands with an emphasis on native plant species.  The wetland area on the west and attenuation pond on the north of the site will create a habitat for breeding amphibian species such as the Common Frog and the Smooth Newt. Through strict adherence to wildlife requirements, we helped to protect existing species and create native environments to allow sustained growth for future wildlife. It’s a good example of how small spaces can have big impacts.

This is also part of our partnership with Host In Ireland’s DC’s For Bees initiative:
