The most pressing environmental challengeClimate change is one of the most pressing environmental challenges that all the nations of the planet have to face. The UN Intergovernmental Panel on Climate Change (IPCC) has pointed out that the global warming of the atmosphere registered since the middle of the 20th century has been caused by human activity. In the last 150 years, the global temperature has risen approximately 0.8 ºC and it is foreseen that it will continue to do so. There changes in the climate are having direct consequences in sectors such as farming, forestry, energy production, tourism and infrastructures in general One of the most vulnerable regions to the direct impacts of climate change is southern Europe, which is experiencing rises in temperature, floods or droughts. In the Basque Country, greenhouse gas emissions (GHG emissions), causing climate change, rose 1% in 2015 compared to the previous year. In relation to 2005, the emissions fell by 25% and were slightly under the path set to achieve the targets of the Basque Climate Change Strategy - KLIMA2050, which establishes a reduction target of 40% for 2030.
