Progressing unfavourable climate change — rising temperatures, changing precipitation patterns, melting glaciers and snow, rising average global sea level, is a reality. To mitigate climate change, emissions must be reduced or prevented. Certain workplaces and industries will undergo changes or disappear altogether as a result of climate change, while others will come into being as we move towards 'greener' economies. Labour law, although not a natural ally in the fight against global warming, can become a very strong partner for environmental law. The Authors point to the obligations of the parties to the employment relationship, which should be reinterpreted to become an effective instrument in this fight. Thus, they start a discussion on the role of labour law in combating climate change.
