Reduction is especially beneficial, as it also reduces the amount of ‘embedded’ carbon used to make the products that are being thrown away as waste. kitchen and garden wastes and paper, out of landfills in order to reduce emissions of methane (a powerful greenhouse gas). Methane forms when organic materials decompose in the absence of air, a process called anaerobic decomposition. This provides a new reason for city officials to focus on diverting biodegradable municipal waste from landfills. Partly as a result, recycling and organic diversion rates, which had declined to single figure percentages as municipal authorities focused on waste collection, began to rise in cities modernizing their waste systems, in some cases dramatically.
Without proper data collection and management, it is difficult to be accountable, transparent and even; to make effective strategies; and to budget for them. The absence of all of this, in turn, creates barriers for modern waste management systems. As the linkages between valorizing and climate change become clear, proper waste handling has become an important tool to mitigate greenhouse gases. This Third Global Report expresses the hope that it can offer optimism that this is a battle to win, regardless of what kind of city decides to join in this fight.
CHAPTER 2 INTRODUCTION AND KEY CONCEPTS INTRODUCING THIS BOOK This publication is UN-Habitat’s Third Global Report on Water and Sanitation in the World’s Cities. It focuses on the state of solid waste management, which is an important challenge facing all of the world’s cities. Previous volumes focused on water supply and sanitation. The book has four main aims: 1 2 3 4 to showcase the good work that is being done on solid waste by cities around the world, large and small, rich and poor; to look at what drives change in solid waste management, how things work in cities and what seems to work better under which circumstances; to help decision-makers, practitioners and ordinary citizens understand how a solid waste management system works; and to inspire people everywhere, in good communication with their neighbours, constituents and leaders, to make their own decisions on the next steps in developing a solution appropriate to their own city’s particular circumstances and needs.
