Case Study 4 Environmental and Social Management Accounting (EMA): Its Contribution

to Business Sustainability Module 5

Princess Pty Ltd operates under the brand name of Fine Chocolates. Princess Pty Ltd is preparing to design and implement sustainability systems and processes for its business creating fine chocolates. You are the assistant accountant and you are advised by the environmental director that electricity is a key resource for the business, for operating and for security lighting. The company operates chocolate crafting and production for 250 days of the year (5 days times 52 weeks = 260 days less 10 public holidays). You report directly to Rosemary Rae, the CFO.

Princess P/L is interested in saving electricity costs, so they are considering changing the type and quality of the lighting in their factory that will last for the next 10 years. Princess Pty Ltd will sell the fine chocolates brand name to a competitor after 10 years from now and cease operating so the owner (sole shareholder) can retire. Internal lights are used from 8.00 am to 5.00 pm each day (Monday to Friday) for 250 days a year. The light bulbs will have to be replaced according to the following schedule: (Note Princess Pty Ltd will not replace the bulbs in Year 10 as the business will stop operating).

After several robberies, Princess Pty Ltd have been given two options. First option is to pay an additional $390 insurance premium each year for the next 10 years. Second option is to install and run security lights from 6 pm to 4 am for 365 days of the year to avoid this additional premium.
