2 Radio and Minimizing GHG Emissions Main directions/activities: Minimizing GHG emissions from radio equipment/systems - The use of advanced technologies, such as modern chips, coding and compression technic, digital modulation allowed significantly reduce power consumption per unit for almost all radio applications. The use of radio-based devices/systems for reduction in other sectors - Wireless devices, such as mobile phones are currently the most common way of communications, which significantly reduce commuting and travelling. Radio, in many cases, is the most economically valuable solution of the last mile problem. Dematerialization through the use of radio equipment/systems – The use of radio technologies, for example satellite systems, paves the way for Internet access from remote areas and allows to apply paperless working methods, switch from physical distribution DVDs and CDs to online delivery. Global Monitoring Carbon Dioxide Emissions - Radio-based devices called remote sensors are the main tool for the global monitoring of GHG emissions.
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Radio-based Devices and CO 2 Emissions It seems that radio-based devices are the most used telecommunication devices. According to the recent statistics there are currently in use: more than 4 billions mobile phones; ~ 2.5 billions radios; ~1.5 billions TV sets; plus many set-top boxes, Wi-Fi cards, powerful broadcasting transmitters, etc. Source: and

ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Minimizing GHG Emissions by Introducing New Radio Technologies An impressive example in this area is a digital broadcasting Plan GE06 developed by Regional Radiocommunication Conference 2006 for 120 countries. GE06 Plan envisages: reduction (by almost 10 times) in transmitter power due to the use of digital modulation. There are hundreds of thousands of transmitters around the world with power of up to kW each. The resulting energy saving is very significant; possible reduction number of transmitters due to the transmitting up to 10 TV programmes in one 8 MHz channel instead of 1 TV programme per channel. GE06 Plan is based on ITU-R and ITU-T standards (ITU-R and ITU-T Recommendations).
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Minimizing GHG Emissions – Standardization Regulations (samples) IEC standard - the world's International standard for measuring the energy efficiency of the latest generation of plasma and LCD televisions and other devices such as cable set-top boxes; European Commission submitted to EU Parliament a report on mobilising Information and Communication Technologies to facilitate the transition to an energy-efficient, low-carbon economy expecting to reap from EU legislation on smart technologies including radio technologies to tackle climate change (see at: h/docs/com_2009_111/com en.pdf ). h/docs/com_2009_111/com en.pdf
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Minimizing TV CO 2 Emissions - Labeling Labeling environment-friendly TVs is another way of minimizing emissions. Some samples: Energy Star programme: based on IEC standard; sets thresholds that would permit about 25% of the TVs on the market to receive the Energy Star label. LCD TV Association Green TV programme: based on IEC standard; sets the energy consumption thresholds of TV sets, regardless of technology; requires incorporation of advanced features such as ambient light sensors and boosting efficiency; takes account number of recyclable parts.
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Reduction of GHG Emissions by Mobile Radiocommunications Main methods: Sustainable energy use based on: use of radio standby mode – power consumption can be reduced up to 40% under low traffic and by 10-20% on overall; optimization of remote radio units by moving RF converters and power amplifiers from the base to top of the tower – reduction up to 30%; use of advanced air conditioners and/or passive cooling systems – 10-15%, etc. Use of green energy – solar panels, wind turbines, etc. These measures in combination with optimal network design and smart antennas will allow to reduce cellular radiocommunication network CO 2 footprint by ~ 50%.
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July ITU-R Activities in Minimizing Power Consumption The World Radiocommunication Conferences (WRCs) facilitate the use of less power hungry radio technologies by incorporating the most efficient ones in the Radio Regulations – international treaty status standard. WRCs also abolish the use of outdated radio-based applications and systems on international level. ITU-R Study Groups carries out analyses and approve ITU-R Recommendation allowing the use of the most environment-friendly methods, applications and systems.
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Dematerialization and Radio In terms of technologies for reducing carbon emission, the use of radiocommunications as a part of telecommunication infrastructure provides means for: reducing business travels by virtual presence (teleconferences) and working at home using remote access tools; online publications of documents; use Internet and specifically IPTV instead of DVDs/CDs; using e-commerce to reduce shopping trips; online billing (to save on paper bills), etc. However, radio, in certain extend, is the next step in dematerialization – it dematerializes wires.
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July ITU-R and Dematerialization and Remote Wireless Collaboration The work of ITU-R Study Groups 4, 5 and 6, on multimedia, is of particular importance, notably in terms of standards for remote wireless collaboration, such as the BO, M, S Series of ITU-R Recommendations on wireless audiovisual and multimedia systems, including video-conferencing, which provides means for people to collaborate/work at a distance without needing to travel (ITU-Ts also develops Recommendations on multimedia).456BOMS
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Climate Neutral ITU – Radiocommunication Sector Role ITU-R and its predecessor IFRB were pioneers in application of electronic methods since 80-th. Few examples: voluminous ITU-R service publications, distributed to all ITU-R Member States on weekly bases, are published on DVD and Internet, that significantly reduced the amount of paper (1 space networks data – up to 1000 pages); WRCs - the biggest ITU forums, are switching to paperless methods of work and reduced number of paper copies. WRC-07, attended by more than 2800 participants, saved several millions pages of paper; Publication of maritime Service Publications in electronic form from 2011 (Res. 335 (WRC-07)) will save about 300 tons of paper per year and reduce the carbon emissions from transporting paper copies; All frequency assignment data (several millions) are available through electronic means.
ITU Symposium on ICTs and Climate Change Quito, Ecuador, 8-10 July Radio and Environment Information Most of people think that the radio frequencies are used for radiocommunications. However, radio emissions are also used for obtaining information about the environment with which they have been in contact. Environmental information, including climate monitoring data, is currently being obtained by special measuring instruments called remote sensors. Remote sensors (passive and active) are radio devices, that derive environmental information by analyzing the characteristics of received radio waves. Space-based remote sensors are the only tools that provide environmental data on a long term, repetitive and global scale.
