On one hand, in North America, Latin America, the Middle East, and North Africa, emissions decreased by between 20% and 30%. Contrary cases were those of Greater China and the Asia-Pacific, the first and second-largest mobile phone markets respectively, where an increase occurred. This is indicated by the fourth Mobile Net Zero report from GSMA, released within the framework of the MWC.

The total carbon emissions from mobile network operators worldwide decreased by 6% between 2019-2022, despite increased demand for connectivity and data. This was achieved thanks to advances in energy efficiency and renewable energies.

More than half of the emissions decrease recorded in 2022 was due to improved energy efficiency in networks, data centers, and offices. On the other hand, renewable energy accounted for 33% of the electricity purchased by operators reporting to CDP in 2022, compared to 14% in 2019.

The goal of the mobile telephony sector to achieve net zero emissions by 2050 depends on the industry reducing its emissions by 45% below 2020 levels by 2030. GSMA's regulatory director, John Giusti, called for government commitment to support the mobile industry in accelerating decarbonization "with a concerted focus on fostering investment in renewable energies, as the lack of access to renewable energies in some regions creates a barrier for operators to continue their journey to net zero".
