||Manual for the Refrigeration and Air-conditioning Technicians and Engineers: Post phase-out period of CFCs and beginning of phase-out of HCFCs
The manual provides new approaches to prevent emissions of CFCs during the operation and servicing of equipment and catalogues steps to recycle the CFCs and retrofit the equipment.
Developing countries, called Article 5 countries under the Montreal Protocol on Substances That Deplete the Ozone Layer are also embarking on the second stage i.e. phasing-out of hydrochlorofluorocarbons (HCFCs), the last remaining refrigerant that is ozone depleting. The manual also contains the guidelines for the prudent use of HCFCs and emission preventing actions. These help countries slow down the growth of HCFCs and ease phase-out efforts.
CFCs and HCFCs are powerful greenhouse gases. Over the past few years the environmental and technical issues surrounding the use of refrigerants have evolved at a remarkable speed. Indeed, the variety and types of ozone and climate-friendly refrigerants currently available are significantly different from those commonly used a few years ago, as is the way in which they may be applied. Using the procedures outlined in the manual would help protect the ozone layer as well as provide other environmental benefits, including some that would help in the fight against climate change.

||Sustainable Innovation and
Industrial Sector Studies: RECYCLING – FROM
E-WASTE TO RESOURCES
The appropriate handling of
electronic waste (e-waste)
can both prevent serious
environmental damage but
also recover valuable materials,
especially different types of
metals such as aluminium,
copper, palladium and gold.
This publication focuses on the
signifi cance and possibilities of
getting resources back out of
e-waste trough a sustainable
technology transfer in the fi eld
of recycling. It provides an
analysis of the transfer potential
of relevant technologies in the
recycling sector in selected
developing countries. Hazardous
elements present in e-waste
are duly considered, and their
proper handling and treatment
is addressed to prevent environmental
or health impacts.
||Common Carbon Metric for Measuring Energy Use and Reporting Greenhouse Gas Emissions from Building Operations
Leading experts from around the world have, through extensive international cooperation, developed a universal method of measuring a building's carbon footprint. Supported by the United Nations Environment Program, this new 'Common Carbon Metric' will allow emissions from buildings around the world to be consistently assessed and compared, and improvements measured.
||Greenhouse Gas Emission Baselines and Reduction Potentials from Buildings in South Africa
This report accompanies the Buildings and Climate Change- Summary for Decision Makers. UNEP-SBCI has commissioned the compilation of regional reports that quantify the influence of buildings on climate change in selected regions. This South African report has been undertaken in collaboration with the Construction Industry Development Board (CIDB).
||UNEP Year Book 2010
The UNEP Yearbook 2010 is essential, informative and authoritative reading and within six chapters the Year Book addresses the following:
In 2009, efforts to advance international environmental governance focussed on defining key objectives and functions for an improved UN architecture to address global environmental change.
Ecosystems are being pushed beyond thresholds. Drivers of change that lead to biodiversity loss and changes in ecosystem services are growing in intensity. Dead zones in coastal areas have doubled in extent every decade since the 1960's.
Much work remains to be done to reduce and mitigate the effects of harmful substances and hazardous waste on human health and the environment. Many unanswered questions remain about nanomaterials.
The effects of increasing atmospheric greenhouse gas concentrations are better understood, as more indicators of climate change are being assessed. Direct observations and modelling indicate that the planet's tropical belt is expanding.
Sustainable natural resource management can reduce vulnerability to disasters and conflicts and support peacebuilding. Promising tools to reduce disaster conflict risks are being integrated into policy and institutional structures.
Better managing material and energy flows will help meet challenges associated with environmental impacts and advance decoupling of economic growth and resource use.

||Towards Sustainable Production and Use of Resources - Assessing Biofuels
The assessment report on biofuels, prepared by the Resource Panel for Sustainable Resource Management, is a flagship publication of the Panel, the first assessment report to come out. It aims at improving the analytical basis for decision making towards sustainable production and use of biomass for energy purposes ("biofuels"), at the international, regional and national level. It focuses on different aspects and options for more efficient and sustainable use of biomass in the overall resource context. The analysis accounts for the environmental effects of so-called "modern" biofuels while considering economic aspects and social concerns, especially with regard to relevant side-effects and potential synergies. The executive summary is dedicated to policy makers and explains in a simple and action-oriented manner the results of the main report. The flyer will report these results to a broader audience.
||UNEP Year Book 2009
The UNEP Year Book 2009 presents work
in progress on scientific understanding
of global environmental change, as well
as foresight about possible issues on the
horizon. The aim is to raise awareness of
the interlinkages among environmental
issues that can accelerate the rates of
change and threaten human wellbeing.
