The tunnel construction consumes resources and energy
and emits a large amount of greenhouse gases into the environment. Through the
longterm exploration of tunnel carbon emission, the current research
progress of China′s highway tunnel carbon emission
calculation, inventory data, impact mechanism and emission prediction are
summarized resulting from difficult collection of tunnel carbon emission
calculation data and difficult estimation of tunnel carbon emission. Firstly,
the calculation methods of carbon emission during tunnel construction are
introduced by investigating the literatures about tunnel construction carbon
emission calculation in China and abroad. And then the calculation methods of
using data inventory and emission coefficients to evaluate carbon emission during
tunnel construction are illustrated with an example, and the contribution of
different construction procedures, materials and energy to carbon emission is
clarified. In addition, based on a large number of calculation results of
tunnel construction emissions, statistical analysis is used to explore the
influencing factors of the carbon emissions during tunnel construction, and the
linear regression method is used to establish the prediction equations.
Finally, in view of the two major problems in the current calculation of tunnel
carbon emissions, i.e. difficulty of obtaining basic inventory data of tunnel
emissions and difficulty of emission data to circulate among different
departments and enterprises, it is proposed to develop resource and energy measurement
and block chain technology to promote the sustainable development of energy
conservation and emission reduction in the tunnel industry.
