Simplifying Sustainability Decisions

SIMAP® is a carbon and nitrogen-accounting platform that can track, analyze, and improve your campus-wide sustainability. Our proven algorithms, based on nearly two decades of work supporting campus inventories with the Campus Carbon Calculator, CarbonMAP and Nitrogen Footprint Tool, will help you:

  • Create a baseline
  • Benchmark your performance
  • Create reports
  • Set goals
  • Analyze your progress year over year

Your Campus Footprint



CO2 emissions from generating power, treating waste, daily commuting, and even the use of paper, contribute to a campus' carbon footprint. Reducing these greenhouse gas emissions will help slow the effects of climate change and global warming.



Reactive nitrogen can result from everyday activities like food service, energy use, transportation, and ground fertilizer. Reducing your nitrogen footprint can provide benefits to air quality, water quality, and climate change.

Subscription Tiers

SIMAP offers two subscription levels (Tier 1 and Tier 2) that help you calculate your carbon and nitrogen footprint at a nominal license fee. We also offer add-on services, such as data reviews and additional user support time.  Our model allows UNH to cover the costs of continuing to offer and support this tool for the good of the entire campus-based sustainability community.
