As world leaders prepare for the COP30 Climate Summit in Belem, experts are calling for a shift from capital-heavy waste-to-energy infrastructure to technology-driven, community-based zero-waste systems that can rapidly cut methane emissions while creating sustainable jobs.
A new policy brief released by the Global Alliance for Incinerator Alternatives, GAIA, proposes that climate finance be redirected toward digital, data-backed zero-waste models that leverage innovation for impact.
According to GAIA, smart waste tracking, decentralized composting technologies, and blockchain-enabled financing tools can make waste management more transparent, equitable, and efficient, particularly in developing countries struggling with urban waste challenges.
GAIA’s Global Climate Policy Officer, Yobel Putra, said: “At the ‘Implementation COP’, leaders must back cost-effective climate solutions that make people’s lives better and leave no one behind,” “Investing in community-based zero waste systems does just that. Our work shows there are shovel-ready projects that need the right financial framework to scale up and deliver.”
GAIA’s toolkit urges governments and financiers to use digital tools to realign incentives and prioritize low-tech, high-impact innovations that make zero-waste systems viable. The group emphasizes that so-called “false solutions” such as waste-to-energy incineration and co-firing should be excluded from investment portfolios because they consume vast public funds, lock in carbon dioxide emissions for decades, and pose public health risks.
It further advocates that climate finance be delivered as grants rather than loans, especially for community-driven waste projects that deliver social and environmental returns rather than financial profit. Projects such as closing dumpsites, cleaning up pollution, and retraining waste workers, GAIA notes, require upfront support for sustainability.
The organization also calls for the adoption of the ‘polluter pays’ principle, supported by digital tax collection and traceability systems. Levies on plastic producers, as well as taxes on dumping and burning waste, can be channeled directly into zero-waste financing. Additionally, GAIA recommends that operational savings from digital monitoring of reduced landfill use, transportation, and waste handling costs be reinvested into worker wages, better equipment, and further innovation in recycling systems.
The waste sector contributes nearly 20 percent of global methane emissions, yet in 2023 it received less than 1.5 percent of climate finance- and 99 percent of that funding went to incineration projects.
GAIA’s research shows that data-driven zero-waste systems, including prevention, reuse, recycling, and smart composting, can cut methane emissions from solid waste by up to 95 percent when implemented at scale.
Across cities like Accra, Buenos Aires, and Quezon City, communities are already deploying digital mapping tools and waste-sorting apps to help informal waste pickers formalize their work, track recycling rates, and attract financing.
GAIA’s Global Zero Waste Cities Program Director, Cecilia Allen, Cecilia Allen, said: “Community-based zero waste systems not only reduce waste disposal and emissions, but they boost jobs, environmental health, and local economies. With public policy and digital innovation support, these benefits can go much further.”
As COP30 approaches, GAIA says the global community must “pay the pickers” -channeling technology, policy, and financing toward grassroots waste solutions that deliver measurable, data-backed climate results.
