The Green Sail Footprint Program

Make sustainability simple. The Green Sail Footprint program is a per-vessel calculation that measures CO₂e emissions and sustainability actions onboard a boat.

We help our Partners to measure their environmental output to develop a concrete roadmap to sustainability.

Cost: €30 per vessel

How the Footprint Works

Step 1

Complete the Green Sail Footprint survey with essential information for each yacht you want to verify, including important data elements such as engine hours and engine models.

Step 2

Once the survey is complete, we will calculate the CO₂e emissions for each of the yachts you have provided data for.

Step 3

Once your CO₂e emissions are calculated, you'll receive a detailed breakdown of your results and gain a thorough overview of your environmental impact. Sustainability actions onboard your vessel will also be published to potential clients so that they can make informed decisions about the vessels they choose to book.

How it’s Calculated

We assess 3 key areas to measure the CO₂e emissions of each vessel:

  • Emissions produced using onboard engines & generators
  • Power usage
  • Water usage

We also calculate sustainability actions and renewable energy sources onboard, making this data accessible to potential clients so that they can make informed decisions about the vessels they choose to book.


We collect data on:

  • Renewable energy sources
  • Water makers
  • Solar panels
  • Waste produced onboard
  • Sustainability actions
  • Recycling onboard
  • Stickers
  • Antifouling processes

Accurately collecting and managing reliable data is essential for understanding where we currently stand and how close we are to achieving our goals. The Green Sail Footprint Review serves as a critical tool, not only for assessing our current position but also for providing clear guidance on the steps needed to move in the right direction.
