Environmental problems (GHG effects, climate change, depletion of the ozone layer, loss of genetic diversity, air pollution, water pollution and others) are the result of human behaviour. (Gardner and Stern 2002). The consequences on the economy, society and health of climate change are one of the
greatest threats that the world faces today, affecting even the survival of the human race (Tonn 2009).
For the Basque Country, the main impacts forecasted for the last third of the century are an increase of temperatures of up to 7º, heavy changes in rainfall patterns and an inland movement of up to 13m in the coastline.
This GHG emission reduction strategy (or mitigation strategy) is addressed to the key decision making authority in the Basque Country It has been made following the five-step approach recommended by Cities for Climate Protection (ICLEI n.d.).
