Beijing has
been grappling with bouts of heavy air pollution since March 9, with the city
being shrouded in smog once again. Although the central and local governments
have made great efforts to cope with air pollution, the problem seems to have
deteriorated mainly due to the inefficient implementation of related air
pollution control measures, according to the Economic Information Daily under the
state-run Xinhua News Agency.
A solution
to the air pollution problem has been bogged down by slow progress in upgrading
the quality and quantity of oil products and modifying industrial structures,
and by conflicting interests among various-level governments coping with the
problem, the report said.
China
announced tighter motor fuel standards in a bid to reduce harmful emissions and
after its long-standing smog problem passed the tipping point — throwing much
of the country into a persistent blanket of hazardous yellow air for the past
two years. The standards, however, will not be fully enforced for another four
years.
The State
Council, China's cabinet, has mandated that sulphur content for both petrol and
diesel be set at no more than 10 parts per million (ppm) by 2017, a reduction
from the current 50 ppm, according to a government statement issued last year.
Burning
fuel with sulphur produces sulphur dioxide, a major air pollutant.
The task of
China's major oil companies in upgrading oil quality is slow and daunting. To
meet the new standards, firms will have to upgrade their refineries in order to
offer cleaner fuel to Chinese consumers, a venture that will require enormous
capital and a long period of waiting before making a return on the investment,
an analyst said.
The chief
cause behind increases in China's smog emissions was the air pollution caused
by fossil fuel combustion.
The
fundamental method for tackling air pollution is adjusting energy
infrastructure and consumption patterns to reduce burning carbon-intensive coal
and other fossil fuels, an expert said.
According
to data, while the consumption volume of coal and fossil fuels in major
industrialized countries and big energy consumers has been declining, China's
consumption volume has grown more than 20-fold over the last half a century.
The country needs to invest more money and resources into the development of
renewal energy, experts said.
Expert Liu
Hanyuan attributed the country's slow development in this sector to the
government's overly conservative policy for promoting renewable energy.
On the
other hand, the central and local governments' failure to fully implement their
policies for air pollution control and clashing interests involved in executing
these policies are also factors hurting the outcome of efforts made to improve
air pollution, Liu said.
