Sustainability in Jordan's Municipal Solid Waste Management System: Reduction of Methane Emissions and Benefits to Public Health

Why It Matters

Methane reductions lower climate warming and prevent costly respiratory illnesses, making waste reform a dual‑benefit lever for Jordan’s economy and public health.

Key Takeaways

• Landfills process roughly 80% of Jordan’s municipal waste.
• Baseline methane could rise 81% by 2050 without action.
• Circular‑economy steps cut emissions 12% by 2030.
• Sanitary landfills and recycling slash emissions 34% by 2040.
• Comprehensive composting and reuse achieve 55% reduction by 2050.

Pulse Analysis

Jordan’s waste sector is at a crossroads. Today, roughly four‑fifths of municipal solid waste ends up in open landfills, a practice that releases methane—a potent greenhouse gas—into the atmosphere. LEAP modeling shows emissions could jump from 4.3 million metric tons of CO₂‑equivalent in 2020 to 7.8 million by 2050, driven by population growth and expanding consumption. The resulting air‑quality degradation fuels ground‑level ozone formation, aggravating asthma, pneumonia, and other respiratory conditions, and translates into an estimated $41 billion in annual health costs by mid‑century.

The research outlines three mitigation pathways. A short‑term circular‑economy focus on reuse and recycling could trim methane by 12% by 2030. Adding sanitary landfills and advanced recycling facilities in the medium term pushes reductions to 34% below the baseline by 2040. A long‑term vision that incorporates large‑scale composting and further reuse drives a 55% cut by 2050. Individual measures such as shifting to incineration or deploying high‑efficiency recycling plants can alone slash emissions by over half, highlighting the potency of targeted technology upgrades.

For policymakers and investors, the findings deliver a clear mandate: modernizing Jordan’s waste infrastructure is not just an environmental imperative but an economic one. The projected health savings alone dwarf the capital outlay required for sanitary landfills, composting sites, and recycling hubs. Moreover, achieving these emission cuts aligns Jordan with global climate commitments and positions the country as a regional leader in sustainable waste management. Stakeholder collaboration—government, private sector, and civil society—will be essential to translate these scenarios into actionable programs that protect public health while advancing climate goals.
