Main Messages
• Waste generation is anticipated to increase by 70% by 2050 with Sub-Saharan Africa and South Asia growing the fastest (35% of global waste by 2050)
• One-quarter of global plastic waste is coming from East Asia and the Pacific with ocean waste primarily coming from 5 countries in the region
• Nearly 50% of solid waste operations involve the private sector, nonprofits or civil society and there is further opportunity to engage

Solid waste management contributes to 5% of global emissions (excluding transportation)
2016: 1.6 billion tonnes CO2-equivalent GHG emissions
2050: 2.6 billion tonnes CO2-equivalent GHG emissions

Waste is overwhelming a predominantly local government
responsibility

Local governments often lack funds, only covering ~50% of
investment costs for waste systems
Remainder comes mainly from the national government
and the private sector 21

Major investment is needed
25
1) Focus on Sub-Saharan
Africa and South Asia
which account for nearly
half of the growth in waste
by 2050
2) Prioritize 5 countries in Asia
to address bulk of marine
litter problem
![Page 26: Global Waste Management Trends · •Waste generation is anticipated to increase by 70% by 2050 with Sub-Saharan Africa and South Asia growing the fastest (35% of global waste by](https://reader034.fdocuments.in/reader034/viewer/2022042022/5e79f138e5ec1e25a914fa74/html5/thumbnails/26.jpg)
Engage the private sector
26
3) Adopt regulations and
incentives to attract
financing and the right
partners—private sector,
nonprofits, or civil society
