PARIS COP-21, ANOTHER FAILED CURE |
Coal emits more greenhouse gas than any other fossil fuel. And
climate scientists have long concluded that burning more coal will undermine
efforts to limit the rise in temperatures. Scientists say the mining and
burning of coal is one of the main drivers of climate change from human causes.
But many developing countries, facing rapid increases in population and surging
economic growth, see coal as a relatively cheap option.
At present Pakistan depends on imported oil for 65% of its
energy, while hydro makes up an additional 30% of the national energy mix:
there are also three nuclear power plants, and wind and solar are fast-growing
energy sources. Until now, Pakistan has not used the bulk of its coal
reserves—some of the largest in the world—for power generation. Not anymore. Last
month the government in Islamabad has signed a number of financial and
technological agreements with China aimed at exploiting massive coal reserves
at the Tharparkar mine in Sindh province, in the south of the country. Under
the terms of the agreements, 3.8 million tonnes of coal will be produced each
year at the Tharparkar open-cast mine to fuel a 660MW power plant and other
facilities. The estimated cost of the project is US$2bn: China’s banks and
private companies will supply US$1.5 billion in loans, while Pakistan will
contribute US$500 m in both private and public finance. The energy produced by
the lignite deposits, one of the least energy-intensive and most polluting
types of coal, at Tharparkar will be mainly directed at helping alleviate
serious power shortages in Karachi, a city of more than 20 million people which
is Pakistan’s main industrial centre. Environmentalists say the new
coal-powered power plants will only worsen the country’s serious pollution
problem. Karachi is already among the world’s most polluted cities.
Despite government declarations that it would prioritise
climate change, Pakistan has shown little appetite for tackling the issue. At
the climate summit in Paris, Pakistan pledged to reduce its emissions of
climate-changing greenhouse gases by 5% over 2012 levels by 2030 – a figure
sharply criticised as being far too modest by a number of the country’s own
climate experts. Pakistan is thought to
be one of the countries most at risk from climate change: in recent years it
has endured a number of floods and droughts, and in the summer of 2015 more
than 1,200 people died in a searing heat-wave.
Another country which is regarded as one of the most
vulnerable countries to climate change is the Philippines and they are planning
a total of 23 new coal plants to meet its demands for energy. For the
Philippines, coal currently generates about 42% of the country's electricity,
with the rest coming from locally-sourced natural gas and renewables, but
coal's share could potentially rise to about 70% in a few decades, according to
some projections.
President Benigno Aquino said that reducing the use of coal
in favour of gas, a popular choice for many, was not an option because of a
lack of gas-importing facilities. He said that although the Philippines had
increased the share of renewables, costs had limited their appeal until recently.
With solar, he said, "the price was considered too high so that it would
bring up all of the electricity rates which would make us not competitive and
will hamper the growth." The costs of solar had now fallen, Aquino said,
but that still left the problem of the intermittent nature of renewables, which
he then chose to spell out. "For instance, if we go to wind, are the wind
turbines really working or not? Solar will get affected by cloudy conditions
like this. Wave action is not yet developed sufficiently to be viable for the
product mix. So what we're trying to do is ensure that we have the most modern
coal plants that are in existence."
Senator Loren Legarda, chair of the country's Senate Finance
Committee said that "doing coal is a crime".
"It's a crime against humanity, it's just bad. It
pollutes the already vulnerable environment, and coal kills - it kills our air,
it kills our biodiversity. Coal is never an option, coal is not cheap. We must
put in the negative effect of the health of the people, the negative effect on
biodiversity, the bad effect on the environment , the bad effect on
business."
But even Legarda does not advocate closing down existing
coal-burning power stations but says the global trend is to move away from coal
and that her country should be part of that movement, particularly since its 98
million people are particularly vulnerable to a potential scenario of higher
temperatures and more violent typhoons. “Why are we approving coal? It does not
make sense. We are victims of climate change and we want to exacerbate it? We
want to worsen the situation by doing more coal? It does not make sense."
