A commitment to reducing environmental impact


Iron Mountain is a signatory to The Climate Pledge™ - committing to achieve Net Zero emissions by 2040, 10 years ahead of the Paris Climate Accord.

By 2040 we will use 100% clean electricity, 100% of the time in our data centers. To accelerate decarbonization of the grid, we are going beyond our RE100 commitment of 100% renewable electricity. We will use the Google methodology for matching site by site electricity use with local clean power generation every hour, every day to achieve 24/7 clean power.

By 2040 we will drive Circular Economy innovation by working toward zero waste in our operations and collaborating with others to create closed-loop Products and Services.

By 2030 all Iron Mountain Data Centers worldwide will be Climate Neutral, as part of our commitment as a signatory to the EU Climate Neutral Data Centre Pact.

We will maintain 100% renewable electricity supply for our global data center business and achieve 90% renewable electricity corporate wide by 2025 -15 years ahead of our RE100 commitment.

By 2025 all new construction multi-tenant data center facilities will be certified to the BREEAM Green Building Standard.

We will go beyond our current Science-Based Target (25% reduction of absolute GHG emissions from our 2016 baseline) and by 2025 will achieve a reduction of 25% of GHG emissions from Scope 1 & 2 energy sources from our 2019 baseline.

By 2023 we will increase our reporting coverage of waste and recycling data to at least 90% of our global operations.
