1. INTRODUCTION
Globally, the waste sector has a relatively small contribution to emissions of
greenhouse gases (GHGs) (3-5% in 2005).
However, the waste sector is in an unique position to move from a small source
of global emissions to be a great saving of emissions.
Prevention and recovery of waste (material and / or energy) avoids emissions in
other sectors of the economy.
Waste and Climate Change. Global Trends and Strategy Framework
UNEP (2010)
Examples:
•EU (27): 140-200 million tones of CO2 eq. (German Federal Environmental Agency, 2005)
•Catalonia: 0.325 million tones of CO2 eq. (Second Study Climate Change for Catalonia,
Gabarrell et al., 2010)

2. WHY ?
Need to develop a tool for calculating emissions of greenhouse gases
associated to waste management at different levels
In the frame of the project
“Low Cost Zero Waste Municipality”
(1G/MED08-533 ZERO WASTE)

2. WHY ?
Need to develop a tool for calculating emissions of greenhouse gases
associated to waste management at different levels
In the frame of the project
Adaptation of the CO2ZW, designed to calculate CO2 emissions in industrial areas
of urban assimilable wastes (organic matter, glass, paper, metals, paper and
cardboard).

•solid waste managers
•academics
•consultants
•policy makers
•NGO’s
The calculator has been designed to function most effectively at the municipality
scale, however it can be used at any scale (including state, country and
region) if sufficient data is available.

access to comprehensive and up-to-date

What it is?
Who can used it?
Tool for calculating the greenhouse gases emissions of waste treatment and
management based on a limited amount of input data.
Any user (waste manager, consultant, researchers) who has updated data of
waste management at local, regional or national level.

5. CONCLUSIONS
… is an easy tool to use and free access to calculate the carbon footprint of
transport and treatment of urban waste for any user
… provides a first approximation of the carbon footprint from raw data (waste
generation)
… provide an estimation of the potential GHG reductions (or additions)
associated with the life cycle of waste management and the technological
changes in the local waste operations
… is suitable for evaluating waste management choices depending on waste
management infrastructures and waste policies jointly with the quantification of
GHG emissions from MSW management, which is essential to guide waste
policy options and climate change solutions.
