This poster focuses on the national level efforts taken in Bangladesh (one of the most climate-vulnerable countries) to face the immediate as well as long term challenges of climate change through green ICT based applications and infrastructure. "Digital Bangladesh" is a vision supported by the Government of Bangladesh (GoB) to integrate the ICT based interventions at every level of life . It envisions the micro-level social inclusion of the base of the pyramid population (BoP) in the mainstream economic activities through ensuring access to information, cost-effective connectivity and efficient e-governance. As climate change is severely negating many achievement made by this developing country, efforts are in place to implement strategies towards developing "Green" ICT based nationwide infrastructure and services all over Bangladesh. This poster looks into the challenges towards fulfilling such objective. It also focuses on the strategic priorities and identifies future opportunities for making a nation's collective effort for a "green" future sustainable. The original research is a part of the ongoing process to monitor and evaluate this national level initiative.
