The LoCaT Project's report on the energy consumption of different methods of watching TV releasedReport
The LoCaT project’s study has been released and we are thrilled to have been a part of this significant project, bringing together broadcasters from across Europe to analyse the energy consumption of different methods of watching TV – antennas, Freeview boxes, satellites and online apps.
We developed our own approach, in collaboration with leading academics in this area. We are pleased that the findings from our independent methodology was aligned with other studies in this area, whilst also providing some unique perspectives. We are very proud to have been a part of it and are excited to finally share the findings with you!
The bottom line is that, for individual viewers, the emissions per hour across all viewing methods are still quite small when compared with other every day activities like driving to the shops. When you’re comparing delivery methods of TV content, the many-to-one distribution of terrestrial TV comes out most efficient when compared to linear TV distributed over the internet. What’s still to be explored is the consequential effects of significant increase in internet traffic from viewing TV will affect the internet energy consumption in the longer-term.
As COP26 starts, the Responsible Media Forum (RMF) have published a summary of the progress the Media Climate Pact signatories have made on:
- Setting science-based targets to reach net zero as early as possible and 2050 at the latest
- Driving climate-friendly lifestyles through content
"The efforts of 7 leading media companies to reduce their emissions and drive behaviour change towards climate-friendly lifestyles through content are encouraging. Systematically putting climate at the heart of editorial & creative decisions would have been unthinkable 5 years ago."
Carbon Trust white paper Report
The Carbon Trust have released a white paper on the carbon impact of video streaming. This publication is an important milestone for DIMPACT, a collaborative project run by Carnstone with the University of Bristol to help the digital media industry map and manage its carbon impacts.
The study estimates the average carbon footprint in Europe per hour of video streaming is approximately 55gCO2e, equivalent to boiling an average electric kettle three times.
It also shows that the viewing devices are responsible for the largest part of the overall carbon footprint. For example, the footprint of watching on a 50-inch TV is shown to be roughly 4.5 times that of watching on a laptop, and roughly 90 times that of watching on a smartphone.
With a powerful foreword by Christiana Figueres, this report is a progress update and a call to arms for media companies. Focusing on what we call the ‘brainprint’, the report is concerned with media’s superpower: the ability to shift hearts and minds, and the enormous social, political and environmental change this can create.
In the report, we explore how the sector’s management of its content impacts has moved on since the publication of Mirrors or Movers I in 2013. Media responsibility has often been creative and innovative, putting the sector’s talents to good use. But our research shows that rigour and measurement now also characterise media responsibility. This is timely, because society's expectations of what it means to be a 'responsible' media company have developed rapidly.
Based on our insights from convening the Responsible Media Forum for over 15 years, as well as interviews with experts within and beyond the sector, the report also outlines a framework for good practice in content impact measurement and six steps to impact.
