Fossil fuels are used for generating more than 50% of electricity in country X. There is an increasing awareness of the impacts of global warming, acidification, eutrophication and photochemical smog on the environment and human health as a result of the combustion of fossil fuels. Golden Light is the company responsible for operation and maintenance (O&M) of street lights in some major cities of country X. The street lights are made of a set (pair) of 400W MH (metal halide) lamps and consume electricity at a cost of $0.30 per kWh. Golden Light employs 25 skilled staff to manage the O&M activities at an average annual salary of $(50,000 + 1600) per employee. Under Environmental Impacts Mitigation protocol, the government of country X is now required to reduce environmental impacts (such as global warming, acidification, eutrophication and photochemical smog) significantly and has advised Golden Light to switch over to green lamps Golden Light has identified 100W LED lamps as a substitute and they wish to make their decision on the basis of environmental, economic and social benefits. Here are some properties of LED lamps. LED lamps do not contain or contain low concentrations of mercury, lead or other toxic materials LED lamps do not emit UV radiation and interestingly, it does not attract insects. LED lamps have a defined beam angle and no upward waste light LED lamps have a longer life span. Most materials used to manufacture LED lamps are fully recyclable Due to the longer life span of LED lamps, Golden Light would have to reduce the number of O&M staff to 15 with an average annual salary of $(50,000 +1760) per employee. Your task is to compare both options and provide assessments on environmental, economic and social impacts to Golden Light Use relevant emission characterization factors (type 1) to perform the following tasks . .

(d) Calculate the impacts on salary and jobs due to this proposed substitution. (e) Develop a TBL (triple bottom line) matrix utilizing the results of this comparative study. An example of a TBL matrix is what was created in Task 2 (Reflective Journal 2, Question 2). (1) Discuss any 2 major findings from the TBL analysis of the two lamp products (g) Discuss 2 sustainability concepts that are promoted in the development of LED lamps.
