A group of Pacific islands have challenged the expansion of a coal-fired power plant in the Czech Republic on the grounds that it could harm the environment.

Micronesia has filed a plea with the Czech environment following the recent Copenhagen talks, which did not yield a strong climate deal, disappointing developing nations looking to mitigate the future impact of climate change.

The Czech power utility, CEZ’s power plant is the 18th biggest source of greenhouse gases in the European Union, emitting about 40 times more CO2 than the entire Pacific island federation, reports Reuters.

The republic has also failed to assess all potential impacts and possible alternatives to minimise the adverse affects of power plants as required under Czech law, according to the Transboundary Environmental Impact Assessment request.

Micronesia’s Office of Environment and Emergency Management director Andrew Yatilman said that the Federated States of Micronesia are seriously endangered by the impacts of climate change, including the flooding of its entire territory and the eventual disappearance of a portion of its state.

“The commissioning or retrofit of any large coal power plant could play a relevant role in the destruction of the entire environment of our state,” Yatilman told Reuters.
