Greenpeace activists climb the cooling tower of the largest and dirtiest lignite power station in Greece. Their aim is to send a strong message to the Greek Prime Minister, Alexis Tsipras, for the need to step up in the COP21 climate negotiations currently undergoing in Paris and transition the country to 0% dirty fossil fuels and 100% renewables.  The Greek government needs to combine climate policy and socially equitable development. This can take place through investing in Greece's greatest asset, the sun.
