The use of mobile technology enabled a global reduction in Greenhouse Gas (GHG) emissions of around 2,135 million tonnes CO2e last year, according to a new study commissioned by the GSMA – a quantity approximate to the total emissions emitted yearly by Russia. The emissions savings were almost ten times greater than the global carbon footprint of the mobile industry itself.
The new GSMA report, produced in collaboration with the Carbon Trust, an independent sustainability specialist, is being presented at the 2019 United Nations Climate Change Conference (COP25) held in Madrid this month. It found that the majority of avoided emissions made possible by mobile technologies were the result of significant reductions in energy and fuel consumption. In 2018, mobile technologies such as Machine-to-Machine (M2M) and the Internet of Things (IoT) enabled a 1.44 billion MWh reduction in energy and saved 521 billion litres of fuel, globally.
“The mobile ecosystem enabled savings of enough electricity and gas last year to power more than 70 million houses for an entire year in the US. Additionally, fuel for all 32.5 million registered cars in the UK to drive for 19 years was saved,” said Mats Granryd, Director General of the GSMA. “Today’s study underlines how mobile and smart technologies are powering sustainable economic growth while enabling the avoidance of emissions across multiple industry sectors. These technologies will be crucial to the world reaching its Net Zero targets.”
“Climate change requires a collective effort across governments, businesses and civil society if we are going to succeed in limiting global temperature increases to within 1.5 degrees,” said Tom Delay, CEO of the Carbon Trust. “This analysis shows the positive role that mobile technology is playing in the evolution of other sectors and is a great example of what is possible.”
The Carbon Trust examined 14 markets around the world to form a representative sample of the ‘enablement effect’ of the mobile sector’s ability to reduce emissions. The results indicate an even split between the enablement effect of M2M/IoT technologies, and those enabled through behaviour changes from the personal use of smartphones.
The majority of avoided emissions from M2M technologies are primarily in buildings, transport, manufacturing and the energy sector – sectors that make up a large portion of global GHG emissions. For example, savings in buildings are a result of technologies that improve energy efficiency such as building management systems and smart meters. In the transport sector, the use of telematics can improve route optimisation and vehicle fuel efficiency.
Meanwhile, personal smartphone usage is enabling emissions reductions due to encouraging behaviours such as reduced travel, increased use of public transport, remote home heating control and online shopping.
The report provides a high-level analysis of six categories of enabling mechanisms, along with case studies. The biggest category of avoided emissions is ‘Smart living, working and health’ (39 per cent of total avoided emissions in 2018), followed by ‘Smart transport and cities’ (30 per cent), ‘Smart manufacturing’ (11 per cent), ‘Smart buildings’ (10 per cent), ‘Smart energy’ (7 per cent), and ‘Smart agriculture’ (3 per cent).
‘The Enablement Effect: The impact of mobile communications technologies on carbon emission reductions’ is produced by the GSMA and the Carbon Trust. The report provides a breakdown of the results and the assumptions used in the calculations, including a full methodology.
