This paper sets out a Sustainable Development Goals Digital Investment Framework which is intended to be the start of a new dialogue with the digital investment community, building on the global Call to Action 1 presented at the UN General Assembly in 2018. It encourages a whole-of-government approach and sets out to help governments address key strategic investment questions and choose effective, scalable technology-based solutions - and in particular help them to onsider using ICT Building Blocks for economies of scale and maximum return on investment.
