The book "Climate Protection and Food Security: A Global Regulatory Approach for CO2 as a Common Good" offers a comprehensive analysis of the challenges and solutions in international climate protection. It highlights the necessity of effectively limiting emissions worldwide and discusses the economic incentives required to promote resource conservation. The author, Ludwig P. Häussner, advocates for a per capita solution that is particularly relevant for emerging countries like India and China. By introducing a pricing model for fossil fuels, an incentive is created to reduce emissions. The book is aimed at professionals and interested parties who wish to engage with the complex interconnections between climate protection and food security.
