Waste to Zero: The Global Initiative for Waste Decarbonisation has published a whitepaper focused on the role of waste as a scalable solution for decarbonisation and a net zero future. The paper was jointly developed by the partners as part of the initiative, including the Ministry of Climate Change and Environment of the United Arab Emirates, Tadweer Group, and Roland Berger. The white paper was launched during a panel session which took place this week at COP29 in Azerbaijan. 

The Waste to Zero initiative's first white paper reveals the waste sector's significant role in global emissions, with methane from mismanaged organic waste alone contributing 20% of global methane levels. By embracing advanced waste-to-resource technologies, such as waste-to-hydrogen and sustainable aviation fuel, the sector holds immense potential for cost-effective decarbonisation. As waste generation surges, innovative tech-driven solutions and essential infrastructure upgrades are critical to mitigating emissions. With over 50 global institutions endorsing the initiative, Waste to Zero champions data-driven, collaborative approaches to transform waste management and support global climate goals. 

Speakers on the panel included Her Excellency Alya Al Harmoodi, Assistant Undersecretary Ministry of Climate Change and Environment - Sustainable Communities Sector, Ali Al Dhaheri, Managing Director and CEO, Tadweer Group, who shared their insights and exchanged thoughts on the initiative. 

Ali Al Dhaheri, Managing Director and CEO, Tadweer Group, commented: “We are honoured to collaborate with the Ministry of Climate Change and Environment, and Roland Berger, in presenting this white paper at COP29. Our findings emphasize the critical role of waste in decarbonisation and achieving net zero, underscoring waste's potential as a transformative asset in climate action. Waste to Zero provides a scalable, impactful pathway to address global emissions challenges, and we look forward to working closely with partners to contribute to 2050 net zero ambitions.” 

Her Excellency Alya Al Harmoodi, Assistant Undersecretary for Sustainable Communities Sector at the UAE Ministry of Climate Change and Environment, added: "The achievements made by the Waste to Zero Initiative at COP29 demonstrate the waste sector's contribution to global emissions and the urgent need for comprehensive action on its decarbonization. The intertwined challenges of climate change and waste demand a consolidated response. Waste to Zero, through its data-driven strategies, provides a platform for stakeholder collaboration and promises to unlock the economic value of circular business models. We remain committed to working with partners from the government and private sector, to support the UAE's transition to a circular economy."

Key Findings

• Waste Sector's Critical Role in Emissions: The waste sector accounts for approximately 3.5% of global greenhouse gas emissions, with methane from organic waste making up 20% of global methane emissions. Mismanagement of organic waste, especially in low- and middle-income countries, contributes significantly to this figure, highlighting the urgent need for improved waste handling practices​.
• High Decarbonisation Potential: Decarbonising the waste sector offers substantial, cost-effective gains in emissions reduction. Advanced waste-to-resource technologies, such as waste-to-hydrogen and waste-to-sustainable aviation fuel (SAF), are identified as critical solutions to mitigate greenhouse gases while creating valuable by-products​.
• Increasing Waste Generation Trends: With current global municipal solid waste production at 2.1 billion tons per year and projected to grow by 50% by 2050, the initiative underscores the growing challenge of waste management amid industrialization, urbanization, and population growth.
• Technology-Driven Solutions for Waste Reduction: Eight selected use cases demonstrate innovative approaches, including AI-powered e-waste recycling, decentralized battery recycling, and construction waste management powered by renewable energy. These case studies show potential to scale and significantly reduce the waste sent to landfills.
• Importance of Infrastructure Upgrades: In many regions, outdated or underdeveloped waste management systems lead to open burning and landfill use, exacerbating emissions. Upgrading infrastructure, such as engineered landfills and advanced recycling facilities, is essential to reduce methane emissions and improve resource recovery.
• Focus on Data-Driven Decision-Making: Accurate data tracking and digital solutions are fundamental to the initiative, enabling transparency, emissions accountability, and impact measurement across the waste management value chain. This ensures that waste reduction efforts are targeted, scalable, and aligned with global climate goals​.
• Cross-Sector Collaboration and Recognition: Waste to Zero has received formal endorsement from over 50 public and private institutions and is recognized as a key initiative by the UAE Cabinet, illustrating the essential role of collaborative efforts in tackling waste-related emissions on a global scale​.
