Japan – eco-friendly airport plan for Narita

Earlier this year, Narita International Airport Corp. (NAA) announced that it had formulated an Eco-Airport Master Plan, which defines detailed environmental preservation activities aiming to make the airport environmentally-friendly



Japan for Sustainability reports that the plan is an airport-wide initiative, led by the Eco-Airport Planning Developing Council, consisting of about 500 business entities operating at the airport. Seven categories have been established in the plan: the local environment, global environment, resources, natural environment, disclosure of information about environmental activities, in-house environmental activities promoted by the NAA administrative office, and sustainable environmental management. The plan sets medium-term targets for fiscal 2006 and long-term targets for fiscal 2010, using fiscal 2002 as the base year.



One of the plan‘‘s goals is to reduce emissions per flight of the air pollutant nitrogen oxide (NOx) and greenhouse gas carbon dioxide (CO2) by 5 per cent in the medium term and 10 percent in the long term. The airport plans to accomplish this through the introduction of more fuel-efficient aircraft and converting vehicles used in the airport to low-emission models, and so on. Moreover, the airport seeks to expand the volume of water recycled on-site from 220,000 cubic meters in fiscal 2002 to 500,000 by fiscal 2010

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...
