ABSTRACT.

We conducted a comparative analysis of in-person, virtual, and hybrid conferences on tuberculosis hosted by Keystone Symposia and examined the number of participants, their country of residence, carbon dioxide equivalents (CO2e) produced, and participant impressions regarding scientific quality. Data were available from three in-person meetings, one virtual meeting, and one hybrid. The virtual conference hosted 2.5-fold more participants compared with the in-person conferences (842 versus an average of 328) from more than double the number of countries (68 versus an average of 33). The virtual conference attracted 4.5-fold more participants from countries with a high burden of tuberculosis, compared with the average in-person conference (209 versus an average of 46). For in-person meetings, an average of 79% of participants were based in high-income countries. For the virtual meeting, 53% of participants were from high-income countries, and 47% from low- and middle-income countries. For the hybrid conference, there were 465 participants from 43 countries, of which 289 attended in person from a total of 20 countries, and 176 participated virtually from 34 countries. Of those who took part in person, 91% were from high-income countries. The average CO2e emissions from an in-person conference was 696 tons of CO2e, with 96.0% from air travel. The virtual meeting produced 0.48 ton of CO2e from electricity usage, a 1,450-fold decrease compared with in-person events. Virtual conferences scored a content quality rating of 87.3% to 90.8% compared with a range of 86.4% to 92.2% for in-person conferences.
