In further discussing other elements of the project with UNIDO, the Secretariat indicated that, considering the amount of CFC consumption in the sector, the fact that only one laboratory is being considered for replacement, and the fact that Mexico already has a large supply of MDIs using both HFA and DPIs from other companies, the project preparation could be done at a lower cost than that requested by UNIDO.

鉴于技术和成本相关问 题;相比企业终身使用 HCFC-141b,采氢氟碳化 物技术的相关运营费用较高;以及相 比 HCFC-141b,其替代物质的全球升温潜能值较高,从而对气候产生负面影响,秘书处 和工发组织对氟氯烃淘汰管理计划第一阶段的替代方法做出了评价(见下文第 31 段的解 释)。

Given the technical and cost related issues; the higher operating costs associated with the introduction of HFC-based technologies as compared to HCFC-141b throughout the life time of the enterprises; and the negative impact to the climate associated with the higher GWP of the alternative substances as compared to HCFC-141b, the Secretariat and UNIDO assessed an alternative approach for stage I of the HPMP (as explained in paragraph 31 below).
