Drought, forest fires, and melting ice caps: the climate crisis is an existential threat to human life on Earth. The Paris Climate Agreement shows that the actions of governments alone will not be enough to prevent a climate catastrophe. For Ferry Heilemann, digital entrepreneur and founder of the Leaders for Climate Action initiative, one thing is therefore very clear: businesspeople need to do their bit to contribute towards global climate protection. How can a business measure its own carbon footprint? How can CO² emissions be reduced in the shortest time possible? What specific steps are required to achieve this? And how can effective alliances be built up between businesses and their surroundings? With the aid of precise checklists, recommendations for practical action, and background knowledge, the Climate Action Guide shows how businesses can implement straightforward measures and make an important contribution to the protection of our planet – in the process also making themselves future-proof. The first action guide for businesses which want to take practical action to protect the climate.
