BCG has launched its Telco Sustainability Index, designed to capture the four dimensions most relevant to a telco’s environmental strategy. The index tracks the company’s commitment to sustainability, its emissions intensity and that of its upstream and downstream partners, its elimination of waste, and its customer enablement.

BCG Telco Sustainability Index: Key insights
Overall Observation
• Over the last years the TMT sector in general and the telco and tech industry in particular have increased their sustainability ambitions:
net zero targets have been pulled forward from often 2050 to even 2035
• The motivation for telco operators is clear: their carbon footprint has exceeded the footprint of the airline industry and will continue
to grow with the increased data transportation in fixed and mobile networks if not managed proactively
• The historical focus of telco operators has been on scope 1 and scope 2 emissions - now scope 3 is very often focused (i.e. covering the
entire supply chain) – two third of all emissions of a telco operator are typically scope 3 emissions
• In addition, “scope 4”, i.e. offering digital sustainability services which enable other industry sectors to become more sustainable, are
becoming more important
• Hence, embracing sustainability is much more of an opportunity for telco operators than a burden – the business potential is enormous!
• Even some consumer segments show an increased interest to buy green telco services/products and even paying more for it!
• While the business opportunity is obvious, telco operators also need to watch out for liabilities in their balance sheets, i.e. (old) assets
that consume a lot of energy – cost of capital will increase and share price will suffer if not managed proactively
Findings of this year's telco sustainability index
• In 2020, performance of top scorer improved further, while bottom scorer had no overall improvement
• European telcos maintain sustainability index leadership
• However, significant improvements can be observed in Europe and in North American as well
• Main driver for 2020 sustainability improvement were the announcement of new targets – execution is still open
• While the best telco operator has reached two thirds of the best possible score, on average the telco industry has not even reached the
50% mark!
• Enabling other industries to become more sustainable is still the most neglected dimension
