Case Studies and Research

We have collated best practice case studies and research from across the mobile industry.

Case Studies

Renewable Electricity

APAC

Across the APAC region, an average 25% of electricity generated through grids is from renewable sources. However, GSMA figures show that operators are currently purchasing around 5% of renewable electricity (RE) to power their networks. Given barriers to companies accessing RE, concerted collaboration is needed between policymakers, energy generators and the corporate sector to increase RE capacity.

Examples:

NTT Docomo Jio

Europe

Mobile networks in Europe are leading globally as they are powered by 71% renewable electricity, on average. Mobile network operators in Europe are also increasingly transitioning from renewable energy certificates to long-term power purchase agreements to secure their renewable energy requirements.

Example:

TDC

MENA

Both the level of renewables on the grid and the amount mobile network operators are currently purchasing are currently low across the Middle East & North Africa (MENA) region, at less than 5%. With COP27 in Egypt, and COP28 planned for the UAE, it is hoped this will spur greater focus and investment in renewable energy capacity across the region.

North America

On average, electricity grids across North America generate 25% of their electricity from renewables. Network operators in the region have scaled up renewable electricity usage and are currently using 43% on average. Operators continue to expand their use of power purchase agreements, for example supporting new solar farm creation.

Examples:

AT&T T-Mobile Verizon

SSA

The Sub-Saharan Africa (SSA) region currently generates 22% of its grid electricity through renewables and mobile operators directly purchase 7% RE on average to power networks. Improving market access to companies for renewable electricity would help turn their purchasing power into support for boosting RE capacity across the region.

Example:

Vodacom

Clean Energy

In Uganda, mobile network operator MTN has installed 240,000 solar home systems delivering clean and affordable energy to two million people. Over 80% of the population do not have access to electricity, which has an enormous impact on the country. Reliance on dirty and expensive forms of energy such as kerosene not only presents huge safety risks, but has larger consequences for the country’s development. MTN Uganda and Fenix International have developed a Ready Pay Power System, which generates solar energy to power lights, radios, televisions and even charges mobile phones. This can be paid off gradually using MTN’s mobile money service, which is accessible to 95% of Ugandans who lack energy access.

Green Electricity

Telefónica has implemented over 700 projects to reduce energy consumption and are making significant efforts to transition to renewable energies in Valencia, Spain. To date, these intelligent insights have demonstrated energy consumption has already been cut by up to 35%. Telefonica has ambitious targets to tackle climate change aligned with the Paris Agreement. In 2016, they launched a Renewable Energy Plan to decarbonize its activity. It will enable them to consume 100% green electricity by 2030, and reduce carbon emissions by more than 50%. Telefonica is currently 100% renewable in Europe and Brazil. The Renewable Energy Plan is a global initiative implemented with a local perspective. It includes renewable purchase possibilities, like long term agreements (PPA), and also self-generation with more than 4300 sites working with renewable electricity. Telefónica was a joint-winner for the ‘Green Mobile Award’ at Mobile World Congress (MWC) 2019

Sourcing Green Energy

Verizon has set a goal to reduce carbon intensity by 50% against their 2016 baseline. Success to date in reducing carbon intensity has been made possible by copper-to-fibre migrations, investments in green energy, building improvements and changes in fleet operations. Carbon intensity progress has increased by 46% towards their 2025 carbon intensity goal.

Digital Transformation to Reduce Emissions

5G Farming

In the Netherlands, mobile operator KPN are using 5G farming techniques to reduce carbon emissions and mitigate climate change. The use of irrigation sensors optimises water management reducing the associated energy consumption. 5G technology precision farming is becoming more accessible to agricultural firms, enabling them to respond almost immediately to developments on their land. As a result, farmers can make savings in areas such as crop protection, to the benefit of the environment. At the same time, the yield is expected to rise, because it is possible to react straight away to the condition of the crop.

e-health

Transfer of health resources and care using ICT to cover three areas: delivery of information for professionals and consumers, improving provision of public health services (e.g.: education and training of health works) and enabling patients to manage their own health. B-Medical systems is a Luxembourg based company who supply and transport vaccines around the world. Using mobile operator KPN’s Internet of Things technology, they developed a smart logger system to monitor their vaccine refrigerators in transit at every step of the journey. The GPS logger works in several ways; constantly ensuring the refrigerator temperature is correct, measuring the ambient temperature and controlling the refrigerator’s door opening. If a problem arises the logger sends a text message to a technician who can fix the problem immediately. The system was designed with developing countries in mind; the logger is easy to use for those with little technical experience and the fridges themselves do not need electricity to work, but can rely on solar power, liquefied gas and kerosene so they can continue to be used for vaccine storage in the future.

E-waste zero program in the Philippines

E-waste generation in the Philippines poses a pressing environmental challenge. With an e-waste generation of approximately 32,000 metric tons annually, the country has a need to implement effective e-waste management strategies.

According to the Philippine Environmental Management Bureau (EMB), e-waste is one of the fastest-growing waste streams in the country. This can be attributed to factors including continuous device production, an increasing number of consumers, shorter device life cycles, and limited repair options. The archipelagic nature of the Philippines also contributes to logistical hurdles.

To address this, Globe established the E-Waste Zero Program (EWZ), formerly “Project 1 Phone” launched in 2014. It advocates for responsible e-waste disposal and recycling, ensuring that e-waste items do not end up in landfills.

EWZ provides a platform for individuals and organisations to donate their e-waste. Individuals may bring their items in one of its 120 collection bins across the country and may also avail of a free hauling service for bulky items.

By upholding the principles of resource conservation, environmental protection, and landfill avoidance, EWZ contributes to addressing the country’s e-waste challenge.

Beyond the take-back program, Globe has also engaged with key community stakeholders including UNIDO, DENR-EMB, EcoWaste Coalition, and the local government of Dampalit, Malabon with funding through the Global Environmental Facility (GEF), to establish a community-based facility for e-waste recycling and job provision for informal e-waste pickers.

Since 2014, EWZ has collected and recycled 216.7 metric tons of e-waste from individuals and organisations and 1,609 metric tons from internal operations. It has deployed more than 120 collection bins nationwide and partnered with more than 80 partner organisations.

To further strengthen the program, Globe will work towards the following:

  1. Program redirection to focus on mobile device e-waste to maximise impact within Globe’s value chain;
  2. Integration of refurbishment and repair practices to extend the lifespan of functional devices; and
  3. Collaboration with key stakeholders, including the government and more recycling facilities to address logistical challenges.

KDDI

VISION 2030

KDDI published a document called VISION 2030 last year with the goal of conveying a comprehensive message to society. The message states that anyone can make their dreams a reality through the power of connection assisted by operators. One of the initiatives in line with this vision is the recycling of mobile phones.

Maintaining a high mobile phone recycling rate is crucial for creating a sustainable society. However, when machines are used to disassemble mobile phones, the plastics from these devices are incinerated, resulting in carbon dioxide emissions and a decrease in recycling rates. KDDI addresses this issue by manually disassembling used mobile phones. Thanks to this approach, they have achieved an impressive recycling rate of 99.8%.

To begin the process, KDDI collects used mobile phones at their stores across Japan. They accept phones not only from their own customers but also from users who purchased their devices from other companies. All collected phones are reset and visibly pierced in front of the customers to ensure that no personal information is leaked.

Expert technicians carefully disassemble each mobile phone by hand, separating them into substrates, LCDs, cameras, plastics, screws, antennas, motors, speakers, and more. Valuable materials like gold, silver, copper, and palladium are extracted from the substrates, while screws and antennas are recycled into iron and steel products respectively. Plastics are recycled to the greatest extent possible.

KDDI’s approach eliminates carbon dioxide emissions associated with machine-based disassembly and minimises material waste. Furthermore, this method of resource recycling avoids the need to extract and refine new minerals such as petroleum, iron, gold, silver, and copper. As a result, there are no additional carbon dioxide emissions.

Launch of the ‘Re’ circular economy initiative throughout Europe

Each year, more than 1.5 billion mobile phones are manufactured worldwide but just 1-2% of these phones are recycled. In 2020, Orange France launched the ’RE’ initiative, based around four pillars: REcycling, REturns (=Buy Back), REfurbishment and Repair. In 2022 Luxemburg, Belgium, Poland, Moldova, Slovakia and Romania, joined the initiative thus consolidating Orange’s commitment to the circular economy in all its activities and practices.

Since its launch in France, the ’Re’ initiative has ramped up the collection rate (recycling and returns) of used mobiles, from 13.4% in 2020 to 22.3% in 2021, in line with the 30% target Orange has set for 2025. In total, around 1.9 million mobiles have been returned and recycled since the initiative launched. The ‘Re’ initiative allows Orange customers to trade in their phone in-store for a discount or credit voucher and buy a range of refurbished phones as an alternative to a brand-new phone. Orange recycles phones that no longer work and/or have no cash value and offer repair services. In France, recycling profits are donated to the Emmaüs International network, as well as two euros for each return. With Orange, all its customers can give a second life to their phone(s).

Alongside existing commitments, this new set of goals is intended to help extend the longevity of mobile devices by giving them a second life, as well as recycling materials to be used in new smartphones.

Proximus

Use, Reuse, Recycle

Under the slogan “Use, Reuse, Recycle” Proximus is committed to a circular economy by extending devices’ lifespan, giving them a second life when possible and collecting old mobile phones to recycle them.

By offering screen protectors, mobile phone covers, damage insurance, and temporary replacement phone in case of theft, loss, or damage, we encourage our customers to use their smartphones for longer. For those who have a smaller budget, or want to adopt an environmentally friendly approach, we have refurbished devices in our offering. We also give a second life on the international market to devices collected that appear after testing to be reusable. This concerns no less than half the collected devices!

It is estimated that 3 million old devices are gathering dust in Belgian drawers … Customers tend to keep them “just in case”. Currently, only 5% of old phones are recycled, while a mobile phone is 90% recyclable. Recycling these old devices allows the raw materials to be reused, thus creating a sustainable alternative to the extraction of natural resources, better known as ‘urban mining’. Urban mining is up to fifty times more efficient than conventional mining.

Proximus collaborates with various partners to make it happen. First, Proximus gathers collected phones in our logistics centre. Then, our partner Brainscape checks whether a phone is reusable and separates out the electronic waste.

The actual recycling of raw materials is performed by Umicore: gold, silver, copper, and palladium, among others, from the circuit boards, in addition to cobalt, lithium and nickel from the batteries.

We collect mobile devices via different channels and incentives:

  1. Our Shops, where customers receive a voucher depending on the residual value of the device
  2. Schools, where our partner GoodPlanet provides educational content to students
  3. Enterprises, via dedicated campaigns
  4. Events and festivals, where Proximus is present with a ‘circularity’ booth

In 2022 we collected 120.573 devices, and we aim to reach at least the same objective in 2023.

Safaricom

E-waste process at WEEE centre

To handle the issue of e-waste, Safaricom has an active partnership with WEEE Centre, a NEMA (National Environment Management Authority in Kenya) licenced e-waste handler. In 2008, the recycling facility ‘Waste Electrical and Electronic Equipment Centre WEEE’ in Nairobi was launched. E-waste is collected across Kenya and brought to the recycling centre, where it is weighed, registered, and sorted for reuse, refurbishment or dismantling for recycling. Some fractions are recycled locally, and others are shipped abroad. Each month, the centre in Nairobi processes up to 10 tonnes of e-waste and, to date, Safaricom has been able to collect more than 1,626 tons of e-waste for the circular economy through the support of WEEE Centre.

In addition, Safaricom has, since 2018, partnered with the Ministry of Environment and Forestry, East Africa Communications Organisation (EACO) and other stakeholders to commemorate International E-Waste Day with the aim of creating awareness on the importance of safe disposal, handling and recycling of e-waste.

Device as a service

Tele2’s Device as a Service (DaaS) solution is a circular service offering centred around the combined offering of leased hardware and services. Since 2021, Tele2 offers the service to its large B2B Enterprise customers and today more than 1 in 5 mobile phones are sold as a service in the segment. The circular offer enables a closed loop for the reuse and recycling of mobile phones. More than 99% of the devices are returned of which 95% can be repaired and reused while the remaining devices are recycled. For every reused mobile phone around 50 kg of carbon dioxide can be saved, corresponding to the production of a new unit, according to Tele2’s recycling partner. By offering this service, Tele2 are meeting a growing customer demand and reducing e-waste, thus creating both business and sustainability value. A circular economy is one of the cornerstones of Tele2’s sustainability strategy, and by 2025 Tele2 will develop winning offerings for relevant customer segments in B2B and B2C based on a circular business model with reduced climate impact.

MARA: How to add value to business & customers through circular economy (Rebuy, Repair and Resell)

MARA is an omni-channel model with an e2e approach to mobile phone reuse.  It aims to boost the circular economy for mobile devices across Telefónica’s footprint. MARA means deploying programs and platforms focused on extending device lifecycle by avoiding repair, taking back, reusing, repairing, and giving them a second life or recycling them.

For instance, in Chile, MARA Care is used to extend device longevity. Using AI it helps customers to proactively detect if a device needs a repair or if the problem can be solved proactively allowing Telefónica to:

  • Reduce Not Fault Found from values circa 20% that have a clear impact on customer satisfaction.
  • Extend the lifetime of devices avoiding unnecessary repairs and logistics movements.

Customers use Mara Care with an omnichannel (retail, remote channels – i.e. online web, chatbots etc.- and self-service) perspective and in different touchpoints along the device cycle. With more than 137K transactions in 2021 globally, it allowed Telefónica to contribute in a significant way to avoid 27.6% of unnecessary repairs reducing carbon footprint and impacting customer satisfaction.

Additionally, in Spain, to incentive sustainable buyback programs, Telefónica uses MARA as a user-friendly way for consumers to trade in their old devices for a new mobile phone. A fully omnichannel process that allows consumers to automatically assess their devices anywhere (home, retail, voice channels). The model provides instant definite value to the customers without device discrepancies – for all parties involved. Also, MARA for trade-in allows to anticipate the most efficient disposition model before collecting the devices, optimising processing time, and logistic movements which implies incremental sources of revenues for Telefónica, such as:

  • Increase by 4 times trade-in volumes in countries where the programme has been deployed
  • Reduction of device discrepancy from 25% to zero along the trade-in value chain process and actors involved: Customers, Partners, Stores and Telefónica.
  • Increase of the device Trade-In voucher by around 14% for our customers

Developing MARA programs across Telefónica is a relevant example of how to promote and lead the transition to circular economy business and minimise the environmental impact and create, at the same time, internal capabilities with an e2e approach.

Telia: Travel Emission Insigh

Telia Travel Emission Insights gives city and environmental planners the tools to take action. It lets municipalities measure and benchmark the CO2 emissions from different routes and modes of transport. Then it helps them to prioritise which actions will have the biggest impact. It also lets them measure, share and report the progress they make.

Telia Travel Emission Insights combines anonymised movement data from Telia’s mobile network with the acclaimed CERO model of CO2 emissions. It’s the key to data-driven decision-making in the fight against climate change.

Telia Travel Emission Insights combine location-specific crowd movement data with the CERO (Climate and Economic Research in Organizations) model. This model was developed at The Swedish Royal Institute of Technology (KTH) and is widely accepted as an accurate way for municipalities and private companies to benchmark their CO2 emissions and set action plans to reduce them in the most economically efficient way possible. Read more about CERO. Telia Travel Emission Insights provide concrete recommendations of actions to take – and what CO2 reductions they can achieve. For transport planners, it answers questions such as: Where should we invest in bus lanes and where should we invest in bike lanes? Where could public transport improvements make public transport faster than taking the car?

For sustainability teams and environmental coordinators within municipalities, it provides a tool to model different scenarios and calculate the results that each could have. This enables more data-driven public spending decisions and the ability to provide transparent reasoning as to why decisions are made and what they expect to achieve.

Mobile Big Data for Cities: Urban climate resilience strategies for low- and middle-income countries

Cities in low- and middle-income countries (LMICs) are increasingly vulnerable to the impacts of climate change, including rising sea levels and storm surges, heat stress, extreme precipitation, inland and coastal flooding and landslides. The physical effects of climate change have disrupted supply chains, led to lost productivity from health issues and incurred costs associated with rebuilding or repairing physical assets, such as buildings and transport infrastructure.

This study highlights the potential value of using mobile big data (MBD) in preparing for and responding to climate-related disasters in cities. In line with the “3As” of urban climate resilience, a framework adopted by the GSMA Mobile for Development programme, this study examines how MBD could help cities and their populations adapt to multiple long-term challenges brought about by climate change, anticipate climate hazards or events and/or absorb (face, manage and recover from) adverse conditions, emergencies or disasters.
