Environment the biggest challenge
By Amitendu Palit (China Daily) Updated: 2012-11-13 08:09The research shows a higher income threshold for GHG emissions than water discharges implying GHG emissions will take longer to reduce than wastewater discharges. This could be due to the continuing reliance of households on fossil fuels like coal for direct energy needs like heating. Alternative heating options using less carbon-intensive fuels are more expensive making it difficult for households to make the switch until their incomes increase substantively over time.
The research also shows that GHG emissions and discharges are first expected to reduce in the coastal provinces of Guangdong and Jiangsu, and coastal cities of Shanghai and Tianjin, and Beijing. But hinterland provinces in Central and West China might take less time and a lower per capita income threshold to start reducing emissions as they begin adopting cleaner technologies faster because of technology diffusion from the coastal regions.
One of the problems in tackling environmental pollution is that its adverse effects are not immediately visible to people. Air and water pollution create major public health hazards like increase in bronchial and respiratory disorders and water-borne diseases and infections. But people realize this only over a period of time, during which pollution and contamination keep increasing, making the problems more serious.
Developing public awareness on climate change is even more difficult. Change in weather patterns leading to irregular rainy seasons and shorter crop cycles, or shrinking water volumes in major rivers because of glacial depression - all caused by global warming - are manifested only over several years and are difficult to comprehend. This is where authorities have to play an important role by first raising people's awareness and then making policies for protecting the environment an immediate priority.
For a large and still developing country like China, adopting policies for protecting the environment has implications for economic growth. Reducing pollution implies shifting to cleaner technologies, which are expensive and increase the cost of production thereby affecting competitiveness of producers, particularly exporters.
For consumers and households, protecting the environment means adopting less-polluting lifestyles through conscious efforts for not polluting surroundings and using less carbon- and energy-intensive appliances. The latter are more expensive and occasionally inconvenient. Solar water heaters, for example, are less energy-intensive, but often ineffective on cloudy days forcing people to fall back on gas or electric water heaters. For both producers and consumers, shifting to less-polluting practices implies higher costs and lower economic surplus.
The balance between high growth and a stable environment cannot be achieved entirely through the market. The State has an important role to play by introducing the right policies. There is need for fiscal intervention both through a pollution (or carbon) tax and environment subsidies. Taxes will discourage polluting practices of both consumers and producers. Subsidies will facilitate greater use of clean technologies.
In addition to these, it is essential to increase public awareness by dedicated efforts at provincial and municipal levels.

I’ve lived in China for quite a considerable time including my graduate school years, travelled and worked in a few cities and still choose my destination taking into consideration the density of smog or PM2.5 particulate matter in the region.
