Can coal be clean?
Currently, over a quarter of the world’s primary energy supply comes from coal. Since the rich world has already created its coal infrastructure, the increased use of coal in China and India is now under scrutiny. In 1980, rich countries used over 65 per cent of the world’s coal; in 2000 their share was roughly 50 per cent. By 2005, this figure fell to 38 per cent as consumption in China and India grew. <br>

Time to ditch Kyoto
The Kyoto Protocol is a symbolically important expression of governments' concern about climate change. But as an instrument for achieving emissions reductions, it has failed1. It has produced no demonstrable reductions in emissions or even in anticipated emissions growth. And it pays no more than token attention to the needs of societies to adapt to existing climate change.

Old clean coal
Energy: Using photosynthesis to capture exhaust gases from power plants could reduce the emissions produced by coal-fired stations T7 OR its supporters, the idea of growing 17 single-celled algae on exhaust gas piped from power stations is the ultimate in recycling. For its detractors, it is a mere pipe dream.

Climate solutions: the WWF vision for 2050
This WWF report seeks to answer the question: "Is it technically possible to meet the growing global demand for energy by using clean and sustainable energy sources and technologies that will protect the global climate?' In other words, can a concerted shift to the sustainable energy resources and technologies that are available today meet the more than doubling of global energy demand projected by 2050, while avoiding dangerous climatic change of more than two degrees Celsius above pre-industrial levels?.
