by Stephen LEE

Requirements of ESG report of listing companies in HK 

Consist of two areas 

A. Environmental 

1. Emissions 

2. Use of resources 

3. Environment and natural resources 

B. Social 

GreenHub focuses on environmental part in the esg report. 

 Suggested KPIs 

KPI A1.1 The types of emissions and respective emissions data 

KPI A1.2 Direct and energy indirect greenhouse gas emissions (in tonnes) and, where appropriate, intensity (e.g. per unit of production volume, per facility). 

KPI A2.1 Direct and/or indirect energy consumption by type (e.g. electricity, gas or oil) in total (kWh in '000s) and intensity (e.g. per unit of production volume, per facility). 

KPI A2.2 Water consumption in total and intensity (e.g. per unit of production volume, per facility). 

KPI A2.3 Description of energy use efficiency target(s) set and steps taken to achieve them.

Methodology (extract data from home assistant) 

Demo (Local hotel) 

A local hotel located in Kowloon with 120 rooms, 25 sq. m on average. 

Step 1, setting up KPIs 

KPI A1.1 The types of emissions and respective emissions data 

- Reduce 20% of overall carbon emissions by reducing the water consumption(reduce by 40%) and electricity usage (reduced by 30%) 

 

KPI A2.1 Direct and/or indirect energy consumption by type (e.g. electricity, gas or oil) in total (kWh in '000s) and intensity (e.g. per unit of production volume, per facility). 

- Reduce 30% of the in-room electricity consumption by implementing GreenHub, encouraging customers to change their behavior to reduce the electricity consumption, particularly in air-conditioning/heater and lighting systems. 

 

KPI A2.3 Description of energy use efficiency target(s) set and steps taken to achieve them. 

- In room consumption, encourage the customer to follow sustainable hospitality habit by following the suggestions from GreenHub 

- Public facilities, more accurate predictions of energy usage, electricity consumption for heating up water for facilities such as swimming pools, spa
