The European Commission has made available a report from telecoms giant Nokia which reviewed life cycle assessment data on mobile phones.
This is the first report in the EC IPP pilot project and serves as a guidance document on the environmental issues in the life cycle of a mobile phone, and shares the findings of the assessments conducted by Nokia and the stakeholders for assessing the life cycle environmental impacts of mobile phones.
The main findings of the assessments are:
· regardless of method, the phases of use and component manufacture are the biggest contributors to life cycle environmental impacts
· in the use phase, the standby power consumption of the charger accounts for the majority of the environmental impact
· in the component manufacture phase, energy consumption accounts for the major portion of the environmental impacts
· the most important environmental issue for a mobile phone is energy consumption
· the printed wiring board (PWB), integrated circuits (ICs) and the liquid crystal display (LCD) are the components with the highest environmental impacts
· in the transport phase, airfreight accounts for almost all the environmental impacts
· collection & proper management of mobiles and accessories at the end of their lives is crucial to have positive environmental impacts from end-of-life (EoL) phase (the positive environmental impacts in the EoL arise from metals recovery
· from the perspective of a mobile system, the energy consumption of radio base stations during the use phase is most significant

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
