Is it possible to subsidize fossil fuels on the one hand, while at the same time claiming to be committed to the fight against global warming? Is it possible to promote free trade treaties throughout the world while claiming that CO2 emissions must be reduced? Can we use indicators that only take into account market production without taking into account pollution?In view of the climate challenge, the answer to these questions should be negative, but unfortunately today it is still positive. In a documented, clear and incisive book, Thomas Porcher and Henri Landes denounce this climate hypocrisy. In the last chapter, they present 10 proposals to meet the climate challenge. Instead of all the great speeches on climate, this book reminds us of the sad reality of recent years—an unprecedented development of polluting energies with unconventional gas and oil, a blind trust in non-existent solutions from the market to fight against climate change, hundreds of free trade treaties being negotiated without climate clauses, inadequate measurement indicators that encourage business as usual.
