The broad and uninterrupted growth, during the last few decades, of the products and services of the information and communications technologies (ICT) industry as well as their omnipresence throughout all sectors of human activity, has lead to significant consequences with respect to the ICT industry's global carbon emission footprint. While this footprint is currently under 4% of global emissions, it is doubling every four years. On the other hand, the ICT industry offers a largely undevelopped capability to generate energy efficiency gains of 800 billion US dollars per year as well as to eliminate 15% of global greenhouse gas emissions, which is equivalent to all emissions of the USA or of China thus creating a huge economic opportunity in the 21st century, carbon-constrained economy. The research program will target the application to telecommunications networks, in the context of the availability of renewable energy resources, of cloud computing and virtualization principles in order to reduce the carbon footprint of these ICT infrastructures while at the same time improving their economic viability. Virtualization of wireless access will be the specific focus as it has received relatively little attention in the open literature compared to virtualization of network backbones and applications. It is notably proposed to apply cognitive radio principles to virtualization of radio access in order to adequately spectral resources and to maximize the use of such resources when they are available. Radio environment maps will also be examined in order to support cognitive functions in a virtualized radio access environment. This comprehensive research program is expected to contribute to groundbreaking outcomes for Canada's telecommunications future and to the training of highly qualified personnel with the technical competence and the vision to use such Green ICT principles as the basis for the 21st century, digital and carbon-constrained economy.

在过去几十年中，信息和通信技术（信通技术）产业的产品和服务广泛而不间断地增长，而且它们在人类活动的所有部门无所不在，这对信通技术产业的全球碳排放足迹产生了重大影响。虽然这一足迹目前不到全球排放量的4%，但每四年就翻一番。另一方面，ICT行业提供了一个很大程度上未开发的能力，每年产生8000亿美元的能源效率收益，以及消除全球15%的温室气体排放量，这相当于美国或中国的所有排放量，从而在21世纪创造了巨大的经济机会，碳约束经济。该研究计划将针对电信网络的应用，在可再生能源资源的可用性，云计算和虚拟化原则的背景下，以减少这些ICT基础设施的碳足迹，同时提高其经济可行性。无线接入的虚拟化将是特别关注的焦点，因为与网络骨干和应用程序的虚拟化相比，它在公开文献中受到的关注相对较少。值得注意的是，提出将认知无线电原理应用于无线电接入的虚拟化，以充分利用频谱资源，并在这些资源可用时最大限度地利用这些资源。还将检查无线电环境地图，以支持虚拟无线电接入环境中的认知功能。这一全面的研究计划预计将有助于加拿大电信未来的突破性成果，并有助于培养具有技术能力和远见的高素质人才，以使用这种绿色ICT原则作为21世纪世纪数字和碳约束经济的基础。
