Top 10 Most Sustainable Telcos

Sustainability has become one of the hottest topics. We’re taking a look at some of the top 10 most sustainable telcos, in no particular order.

In recent years, sustainability has become one of the hottest topics around the world in pretty much every industry. Before this, the ICT industry’s impact on the planet went under the radar for a long time, however, in light of the recent COVID-19 pandemic, the spotlight is now being shone on the industry’s environmental impact with a call for many companies to do better. According to a BCG report, the ICT industry accounts for approximately 3% to 4% of global CO2 emissions, which is about twice that of the civil aviation industry. The telecommunications industry represents a sizable portion of the ICT industry, therefore, most major telcos have agreed to work towards carbon neutrality by 2050, which is a goal supported by the GSMA. 

The vital role that the mobile industry plays in society came into sharp focus during the pandemic, when billions of people became reliant on mobile technology and connectivity in nearly all aspects of life. For example, by the end of 2020, approximately four billion people, which is equivalent to 51% of the global population, were using the internet, an increase of 220 million since 2019. Therefore, with many people and other industries becoming reliant on the ICT industry, there is a major focus on sustainable development and a huge strive for companies to become ‘green telcos’. 

Green telcos are telecommunications companies who are adopting green and sustainable business practices. They are becoming increasingly more visible in the industry and according to the GSMA, the mobile industry is already halfway to maximising its impact of the Sustainable Development Goals. 

Taking all this into account, we’re taking a look at some of the top 10 most sustainable telcos, in no particular order.
