If we're to avert catastrophic climate change the world must quit coal. But the industry and the powerful forces which rely on it won't go down without a fight. Yesterday, in Warsaw, Greenpeace provided them with two reminders of why we all need to quit coal.
Our activists dumped coal on the doorstep of a luxury Warsaw hotel, where industry ministers from 20 countries are meeting to discuss coal's future, unveiling a banner saying 'Get serious, quit coal!' We also published a report on the "True Cost of Coal" estimating the annual financial costs of coal's climate impacts, health impacts and the cost of deadly mining accidents.
Hosted by the Polish government, the conference documents claim that the meeting is being held to agree on policies to help the climate - but the agenda reveals it is about saving profits, not the planet.
