Executive Summary
Life cycle assessment if one of the common methods of evaluating whether a product or system
is sustainable or not sustainable. A life cycle assessment is a practice of compiling and
evaluating the inputs, outputs and the potential impacts on the environment of a product. A life
cycle of a product is the entire period of its existence right from the raw material stage to the end
products and the by- products (Pilselli & Federico, 2019).
A life cycle assessment of two alternative products have been considered. The two products that
have been considered are the electric bulb and a kerosene lamp. The two alternative products are
used to provide light at home and in offices. The life cycle assessment report demonstrated that
the use of kerosene lamps produces a carbon into the atmosphere. Excessive release of carbon
into the atmosphere may lead to the depletion of the ozone layer. The depletion of ozone layer
can easily lead to climate change (Karabegovic & Isak, 2019).
On the other hand, the use of an electric lamb is relatively safe compared to the use of kerosene
lamp. However, the source of energy or electricity for an electric lamp should be controlled. The
use of an electric lamp will be sustainable if the source of electricity does not cause any change
on the environment. Some of the sources that are environmentally friendly are: Wind energy,
solar energy and the geothermal energy (Mannina & Giorgio, 2019).

Introduction
Problem Definition
A source of lighting is a requirement in all homes and offices. There are several alternative
sources of light at home and at the offices. Some of the common sources of light include: The
sun, electricity and the lamps powered with kerosene. The question is to find out whether the
choice of a source of light is environmentally sustainable (Mannina & Giorgio, 2019). To answer
the question of whether the source light is sustainable, a light cycle assessment is necessary. In
this report, a life cycle assessment of a kerosene lamb and a light bulb has been conducted
(Karabegovic & Isak, 2019).
A life cycle assessment provides the impact of the product right from the raw material stage to
the end product and by-product. The effects of the product during the life cycle determines
whether the product is environmentally sustainable or not (Kaltschmitt & Martin, 2019).
Service wanted
The service wanted is the lighting system at home or in the office.
Two alternatives
The two alternatives available are: The kerosene lamb and an electric bulb. The two alternatives
can be used as a source of light at home.
Reason for Choosing the problem
A source of light is a basic item at homes and at offices. A source of lighting is required both at
night and during the day. Therefore, there is a need to have an environmentally sustainable
source of lighting (Diaz-Sarachaga, et al., 2019).
