Safe Use of HCFC Alternatives in Refrigeration and Air-Conditioning: Higher toxicity refrigerants
United Nations Environment Programme

As the phase out of hydrochlorofluorocarbons (HCFCs) progresses, it is expected that there will be a considerably higher uptake, in particular in developing countries, of ‘alternative refrigerants’, such as hydrocarbons, ammonia, carbon dioxide, unsaturated hydrofluorocarbons (HFCs) –or HFOs. Many of these alternative refrigerants have particular characteristics in terms of toxicity, flammability and high pressure which are different from those used previously such as chlorofluorocarbons (CFCs) and HCFCs. When refrigeration and air-conditioning equipment is installed, serviced, repaired and dismantled, safety issues need to be carefully evaluated and considered particularly when servicing technicians have to deal with refrigerants with properties that they were previously not familiar with. It is therefore important that the refrigeration and airconditioning industry adapts to both the technical and safety issues concerning these refrigerants.

Destitution, Distortion and Deforestation: The Impact of Conflict on the Timber and Woodfuel Trade in Darfur
United Nations Environment Programme

There is growing concern about the environmental impact of conflict in Darfur, in particular the impact on Darfur’s forest resources, which were already being depleted at an estimated rate of one percent per annum before the conflict. This study begins to investigate these impacts by exploring how the trade in timber and woodfuel has changed since the conflict began, exploring the impact of the massive displacement of Darfur’s population to the main urban centres, of the unprecedented international presence in Darfur, and of humanitarian programming. te this urgent agenda.
