This special issue amplifies the contributions of technical communicators working on climate justice initiatives across the Majority World. By Majority World, we refer not to a specific geography but to the conditions in which most of humanity lives: lacking economic, social, and/or political agency, and absent adequate institutional access to critical infrastructures. The articles in this issue make explicit the need for TPC scholars to rethink, update, and engage in spaces of environmental injustice.

This article reports findings from a month-long research project in Vietnam working with the Vietnam Association for Victims of Agent Orange (VAVA). The authors found that VAVA did not always abide Western prescriptions for “good” technical and scientific communication yet were extremely effective technical communicators among victims and families. This article reports findings that call for an expanded definition of what it means to practice good technical communication, especially in understudied cultural contexts.
