About us

Why we built Rappel.

Companies of all sizes want to take climate action, but those with lean sustainability resources struggle with gaps in the capabilities, resources, and funds required to get started and maintain progress.  

Rappel has been designed from the ground up to solve these challenges.

‍We provide a streamlined, capability-building engagement process with the power of advanced carbon and financial modeling software to deliver company and asset-specific decarbonization solutions.

‍Rappel builds company value through high return-on-investment decarbonization planning and execution.

‍We deliver tailored decarbonization solutions that are more actionable than compliance-focused carbon accounting software and more affordable than labor-intensive sustainability consultants.
We’re hiring!

Scaling decarbonization means thinking differently.

We are looking for passionate professionals experienced in energy, software, and customer delivery to accelerate our mission of decarbonizing thousands of businesses.
