Rocky Mountain Institute has released Green Footstep - a free online tool for architects, engineers, and developers, which reveals design targets to achieve carbon neutrality in building construction and retrofit projects.

While many carbon calculators are available online, none address multiple building emissions over the building lifetime. Green Footstep also shows designers how to comply with specific design goals such as LEED’s energy credits and the 2030 Challenge - the organization that has challenged designers to make all new buildings carbon neutral by 2030.

In addition, Green Footstep is an educational tool that helps users understand a building’s life cycle carbon footprint. Green Footstep’s website  provides case studies so users can see how the tool has worked in past projects. Users can create a login to save and reload their own projects as they work on them.
