The world has achieved remarkable economic growth in the last several decades, generating significant wealth and prosperity for millions of people. However, this rapid urbanization and economic growth has also resulted in critical environmental and human health problems: rising consumption among urban populations is leading to a dramatic increase in the production of waste materials, contributing to rising costs, social disruption and environmental degradation. Currently, managing waste is one of the main challenges in the developing countries and the amount of municipal solid waste generation will nearly double worldwide by 2025. About one to two thirds of municipal solid waste generated in low and middle-income countries are not properly collected and the heap of uncollected waste are dumped or burned on the streets and vacant lands. Further, the collected waste is transported and dumped to designated sites in a more or less uncontrolled manner. Such landfills are the third largest source of anthropogenic methane (CH4) emissions, accounting for approximately 11% of estimated global methane emissions. The municipal solid waste is also a significant source of black carbon through open burning of waste its transport by outdated and polluting vehicles.

At global stage, the international community saw the conclusion of two key international agreements in 2015 to address the common challenges of the people: Paris Agreement and Sustainable Development Goals (SDGs). Building a low-carbon, resource-efficient, and sustainable society is, today, an imperative that requires our collective actions in each country, city and community.

Through shifting from waste management to resource management – that is, from end-of-pipe solutions to more holistic integrated approach, the resource/waste sector has a major role to play in advancing such transition to a low-carbon/resource-efficient society, and in addressing both climate and resource concerns. In this regard, there is a growing needs among developing economies and economies in transition for policies, financing, technology, infrastructure and capacity development for establishing a sustainable society.

Establishment of CCET

In its most recent decision 27/12 on Chemicals and Waste, the United Nations Environment Programme’s Governing Council requested to continue to facilitate cooperation and coordination across international efforts focusing on waste prevention, minimization and management. In addition, the United Nations Environment Programme’s Governing Council decisions of 25/8 and 26/3 calling on to support national implementation of integrated waste management and to the Rio +20 call for the development of comprehensive national and local waste management strategies, policies, laws and regulations (paragraph 218 of the outcome document “The Future we Want”).

In this context, the Institute for Global Environmental Strategies (IGES), together with the United Nations Environment Programme have launched a joint partnership initiative – the IGES Centre Collaborating with UNEP on Environmental Technologies (CCET) – on the side-lines of the twentieth session of the Conference of the Parties to the United Nations’ Framework Convention on Climate Change (UNFCCC-COP 20) held in Lima, Peru, in December 2014, in order to assist countries, regions and cities in developing waste management system that can minimize negative health and environmental impacts and in enabling the transition to resource-efficient sustainable societies.

To this end, CCET delivers various projects to enhance waste management capacity in partner countries and cities, especially within rapidly growing nations, through dissemination/mainstreaming of the climate-conscious waste management, holistic waste management, and the 3R policy; development of knowledge products; and delivering capacity development program.

Collaboration with International Environmental Technology Centre (IETC)

CCET was founded with the aim of also enhancing collaboration between IGES and the United Nations Environment Programme International Environmental Technology Centre (UNEP IETC). Accordingly, CCET works in collaboration with IETC in support of its work and expanding its reach and delivery in global society, including carrying out the organization’s mandate in promoting the application of environmentally sound technologies and improving waste management in developing countries and countries in transition.

In this regard, CCET currently provides expertise to support the development of national, regional and city waste management strategies and action plans with pilot demonstrations that can be replicated and up-scaled, develops knowledge products for assisting decision-makings and implementation of waste management services, and engages professional communities and wider public for enhancing network and outreach.
