Inspired by MIT’s Office of Sustainability’s Business Travel Dashboard, JHU’s International Vaccine Access Center (IVAC) has won an award to create a dashboard that depicts/visualizes JHU’s business travel emissions data for a JHU-affiliate audience. This data is pulled from travel expense data submitted via Concur (JHU’s reimbursement application).
IVAC demoed this tool at JHU’s Symposium on Sustainability, April 2, 2025.
- Users develop a common understanding of the global impact of JHU business travel.
- Users change their decision-making process to consider emissions as well as schedule and cost when booking travel.
- Users make requests to incorporate additional information to better inform their decisions.
- Communicate the climate emissions impact of business travel to faculty and administrative leaders about.
- Enable a holistic accounting for a portion of scope 3 emissions, which are often much larger than other types of greenhouse gas emissions for universities.
- Foster an enabling environment for mitigation efforts to address scope 3 which will follow on later and be driven by faculty priorities.
- map using D3.js and Natural Earth GeoJSON
- emissions calculator using Carbon Interface Flights API and The Global Airport Database
GovEx accounts were created for the implementation and deployment of this project at Netlify, and Carbon Interface by Heather Bree. Analytics for this project can be viewed in GovEx's Google Tag Manager Dashboard. SSO authentication is configured under the GovEx owned JHU IMI account.
This repository features two branches, main and staging, that are each tied to an automatic netlify branch deployment on push.
Development workflow:
Local branch -> Staging -> Main
Scripts used to process data can be found in a separate repository. Scripts output JSON files that replace the *_rows.json files in the public data folder. To update data new source files must be requested from JHU Travel and processed with these scripts.
