Lum Chang is committed to operating in an environmentally responsible manner, ensuring the long-term sustainability of its business, the environment, and the community at large. One of its key initiatives to achieve this is through decarbonization efforts. GreenA Consultants has been onboarded as the Sustainability Consultant to calculate Scope 1, and Scope 2 for six of Lum Chang’s sites. The sites are:
GreenA adopted the GHG Protocol Corporate Standard to classify the company’s GHG emissions into different “scopes”.
Scope 1 Emissions:
Direct emissions from diesel and petrol for selected owned Company Vehicles. Standards, methodology, assumption and calculation used:
The annual petrol consumption was first converted from litre to tonne. The obtained value is multiplied by net calorific value (44.30 GJ/tonne) and carbon emission factor (69.30 kgCO2/GJ). It is then subsequently divided by 1,000 and converted to tCO2e.
For diesel, the annual diesel consumption was also converted from litre to tonne. The obtained value is then multiplied by the net calorific value of 43.00 GJ/tonne and the carbon emission factor of 74.10 kgCO2/GJ. Next, it is then divided by 1,000 and covered to tCO2e.
Scope 2 Emissions:
Indirect emissions from the purchased electricity, after accounting for the solar energy generated by Lum Chang (exported to the grid) for selected sites. Standards, methodology, assumption and calculation used: The annual electricity consumption was compiled from the monthly electricity consumption and the obtained value is multiplied by the electricity grid emission factor of 0.4057 kgCO2/kWh. It is then divided by 1,000 and converted to tCO2e.
