1 Introduction

Environmental Resources Management (ERM) was commissioned by the Ministry for the Environment (MfE) to conduct a life cycle assessment (LCA) of Product Stewardship Options for Mercury-Containing Lamps in New Zealand.  This report provides the results for the LCA study. 

The LCA study conforms to the ISO 14040 and 14044 standards (2006 and 2006a) for LCA and has been externally reviewed by a panel of LCA experts as described by the standard. 

The goal of the LCA study was to determine the environmental impacts of alternative lamp management options for different mercury-containing lamp types in order to inform the development of a product stewardship scheme for lighting in New Zealand.

The following typical lamp technologies have been assessed:

  1. compact fluorescent lamps (CFL);
  2. linear fluorescent lamps (LFL); and
  3. mercury-containing gas discharge lamps (HID).

The LCA study assesses all life-cycle stages, from mining/production of raw materials to manufacture, distribution, product use and end-of-life waste management.

The results of the study are intended for both internal use and for external communications
