Towngas has committed to monitoring the
Company’s GHG emissions and has devised
strategies for supporting an overall reduction. We
conducted a company-wide carbon audit aligned
to ISO 14064-1 standard to quantify and accurately
report our GHG emissions. Apart from using
natural gas and landfill gas to produce town gas,
we also enhance energy efficiency at our Tai Po
plant. A waste heat recovery system was installed
to recover and reuse waste heat generated by the
gas-production process. This helps cut carbon
emissions by 2,700 tonnes each year.

The emission factors of GHG emissions due to the consumption of electricity are obtained from the sustainability reports of the
two local electricity companies, which were released one year prior to our reporting year.
