and Reinvestment Act (ARRA) was signed into legislation by President Obama. The bill allocated over $90 billion to be invested in green initiatives (renewable energy, smart grids, energy efficiency, etc.) In January 2010, the U.S. Energy Department granted $47 million of the ARRA money towards projects that aim to improve the energy efficiency of data centers. The projects provided research to optimize data center hardware and software, improve power supply chain, and data center cooling technologies. Green Digital Governance Green digital governance refers to the use of information and communication technology (ICT) to support environmentally sustainable policies and practices. It describes a strategy with which an organisation strives to align its information and communications technology with sustainability goals. This can include using digital tools and platforms to monitor and regulate environmental impact, as well as promoting the development and use of clean and renewable energy sources in the technology sector. The goal of green digital governance is to reduce the carbon footprint of the digital economy and to support the transition to a more sustainable and resilient society. Both the green and the digital transitions are high on the agenda for most European countries, as well as the EU as a whole. Documents and goals such as the European Green Deal and the Sustainable Development Goals, fit for 55, Digital Europe and others have set the political changes in motion. At the same time, these two transitions often contradict each other, as digital technologies have substantial environmental footprints that go against the targets of the green transition. The European Union sees digitalisation and the adoption of ICT solutions as an important tool for creating greener solutions, while also acknowledging that in order to achieve the desired positive environmental impact, the tools themselves must be environmentally sustainable. The green transition accelerates innovation and adoption of digital solutions and offers the ICT sector new opportunities for becoming more competitive. The synergy created as a result of the green transition and digitalisation brings social, economic and environmental benefits, which is the main goal of the environmentally friendly digital government and the creation of green ICT solutions in general. The digital component should also be used to reach the ambitions of the European Green Deal and the Sustainable Development Goals. As powerful enablers for the sustainability transition, digital solutions can advance the circular economy, support the decarbonisation of all sectors and reduce the environmental
