The waste sector accounts for 2.8% of global greenhouse gas emissions and is expected to rise 1.7 billion tons annually by 2020 (IPCC 2007).

Overview

Emissions from waste are primarily the result of landfill methane and releases of methane and nitrous oxides from wastewater. Although post-­‐consumer waste contributes less than 2.8% of total global greenhouse gas emissions, it is a sector where there is significant potential for reduction of emissions (IPCC 2007). Waste can be an economical source of energy, either through capture and combustion of methane released from waste or through incineration of certain wastes. The infrastructure needed to support better waste management often requires a large upfront expenditure, which in turn requires capital or financing.

Opportunities

There are a range of mature and effective technologies that are already available for deployment, many of which generate revenue. Geographical, political and financial capacity differences have led to different types of technologies being adopted globally. Identifying way to finance waste projects will unlock technology markets, with a number of technology solutions for both material and water waste, including collection and transport, reuse and recycling, and treatment.
