Telehealth emission research has gained increasing attention from the post pandemic era, as evidenced by a rise in publication, reflecting a growing concern for the environmental impact of human activities. Its platforms have potential utility for providing practical ways to reduce travel demand, lower personal costs, and expanding access to care and benefits through environmental and digital equity. This systematic review analyzed 124 peer-reviewed studies to evaluate measurable sustainability outcomes relevant to a Mid-Atlantic U.S. city. Using PRISMA 2020 guidelines, the review extracted quantitative indicators across environmental, economic, and social dimensions. The results show that 69 studies reported environmental or emissions outcomes, with CO₂ referenced in 54 occurrences and greenhouse-gas measures in 22 occurrences. Distance-based emissions estimation appeared; 38 counts, while life-cycle assessment appeared; 20 counts, indicating that most studies relied on direct travel-replacement calculations rather than full energy-system modeling. Despite these efforts, 46% of studies did not specify any valuation method, limiting comparability and reducing the usefulness of reported emissions data for policy or Benefit–Cost analysis (BCA). Economic measurement was more frequent; 78 studies documented patient-time or travel-savings, and 66 reported system-level cost changes, though only 11studies conducted formal economic evaluation. Digital-inclusion conditions were less consistently reported, with 32 studies measuring broadband, device access, or digital readiness, despite 72 studies focusing on underserved populations. These gaps show that environmental and equity benefits often depend on digital access that is uneven across urban regions such north central Maryland From all purpose, the evidence indicates that telehealth can efficiently reduce emissions, save time for patients, and ease transportation burdens, but stronger methodological reporting and clearer integration of digital-equity factors are needed to support Mid-Atlantic sustainability planning and engineering-education efforts. The review provides a foundation for improving telehealth evaluation tools, teaching sustainability modeling, and informing future Benefit–Cost guidance for digital-health initiatives.
