Purpose Net Zero

Purpose Net Zero is the simple sustainability solution for live events.

Our EPA/EU formulated event emissions calculator measures for the largest emissions factor, travel. Accounting for an average of 70-90% of overall event emissions, i.e. those related to the attendee travel footprints, Purpose Net Zero is a simple solution to facilitate conscious connection.

ReScore

The Council for Responsible Sport has a new, free tracking tool that is web-based called ReScore. And there's a free GHG (greenhouse gas) tracking tool that is easy to use.  There's a 15 minute how-to-use-this tool video that walks you through all of its functions, and shows where you need to put in information, and where to find that information. I would say if someone carves out anywhere between two to five hours they can get a good idea of their GHG emissions. There only needs to be basic information like, how many generators did you use on the day? And for how long did they run? How much square footage of rented space did you use? If you were at a convention center, how many miles did your staff travel running errands?

GET (Green Events Tool) - Free

The GET helps organizers in calculating the carbon footprint generated due to events. GET’s carbon footprint calculator originated on UN Event GHG calculator. The calculator helps organizers estimate their GHG emissions prior to the event and later measure and compare their actual carbon footprint after the event. Offering a wide scope of GHG calculation, the tool covers carbon emissions linked with venue, international flight travel, local ground transportation, audio-visual systems, accommodation, exhibition and production, communications and catering activities.

Digital Event Carbon Calculator

Did you know that a six-hour online event for 4,000 people causes roughly the same carbon impact as a return flight for one person across the Atlantic? You’ll need some basic datas including total event participants, event duration, event shipments, pre-recorded content. This calculator was created by MeetGreen and Clear Current Consulting. The tool is free, but there is a tip jar at the end of the tool (please tip!).

Green Production Guide

This tool was created for the film industry, but it can work for event tracking as well. The PEAR (Production Environmental Accounting Report) is a tool to measure the environmental impact of your production based on the energy used in offices and on stages, the fuel used in vehicles and generators, and the emissions from air travel and accommodations. The PEAR can also report on waste, donations, and other environmentally-impactful purchases like water bottles, plywood, and paper.
