In today's world, where environmental issues and digital advancements are on the rise, educational systems are increasingly turning toward technology to boost climate literacy. This review examines how digital platforms, mobile apps, immersive environments, and gamification techniques are used to support environmental education in both formal and informal settings. The overarching research question is: What digital tools are being used to teach environmental education and what evidence is there that they improve climate literacy and engage learners? By applying clear inclusion criteria, this review pulls studies published from 2010 to 2024, sourced from databases such as Scopus, and Web of Science.

We assessed the selected literature for methodological quality and sorted it into four key categories:
(1) digital delivery formats;
(2) teaching designs and user interaction;
(3) measurable learning outcomes; and
(4) accessibility and adaptation across various educational systems.

The results show that interactive and gamified digital tools boost student engagement, systems thinking, and changes in climate-related behavior. Some of these interventions include location-based simulations, real-time environmental data dashboards, and collaborative online platforms for peer learning. However, challenges such as unequal access, localisation issues, and alignment with national curricula remain significant hurdles, especially in the Global South. This review emphasises the importance of co-designing digital environmental education tools with educators, learners, and community stakeholders as well as investing in teacher training and equitable infrastructure. Digital education tools that are well integrated can be powerful resources for enhancing environmental learning if they are pedagogically sound and tailored to the context.

Keywords: Digital environmental education, virtual learning tools, gamification, climate literacy.
