It has been 15 years since the signing of the Kyoto Protocol in 1997, which aimed to help nations reduce their greenhouse gas emissions and avoid the harmful effects of climate change.

ITN Source has all the images you need to illustrate the steps towards controlling these manmade emissions, with footage covering sustainable lifestyles, alternative energy, protests, and summits.
