A Green Energy Business
As the first step in the operating of a green energy business, we comply fully with
international environmental regulatory requirements as well as with leading global
practices. Our operations and operating systems together with our Environmental
Management System in Hong Kong gained accreditation under the internationally
acclaimed ISO 14001 environmental management system standard in 2000, certifying
that our gas production processes are on par with the cleanest and most efficient
industrial systems around the world.
“Towngas’ utilisation of
landfill gas as a production
fuel along with natural gas
demonstrates the use of
cleaner energies in town gas
production. In particular, the
use of landfill gas provides
a win-win scenario as it is
a renewable energy which
would otherwise be wasted.”

Clean Energy
Gas is a cleaner source of energy than other
energy alternatives, with the use of clean
fuels such as natural gas, currently the
cleanest fossil fuel available, our business
is very much a green energy business.
Extending this positive picture, we have
taken a strong interest in turning traditional
waste materials – the use of landfill gas
and coalbed methane, for example, into
valuable sources of energy and we are also
highly active in the exploration, research,
development and discovery of the new
and non-conventional forms of energy.
In addition to our widespread work in the
use of clean coal utilisation techniques for
example, we are also actively exploring the
use of biomass energy.
