'The 2020-21 pandemic crisis confirms the opportunity for integrating environmental taxation into the core structure of fiscal systems. Carbon taxes, resources taxes, removal of environmental harmful subsidies allow labour taxes to be abated substantially. Economic instruments might not be ''the'' solution, but they are certainly ''par'' of the solution if we wish to achieve the ambitious but necessary objectives of the UN SDGs, Paris Agreement, CBD on biodiversity and natural capital. We have here substantial contributions with robust analysis that can be used by all Governments and researchers.' -- Aldo Ravazzi Douvan, Italian Ministry of Ecological Transition, Past Chair OECD Committee on Tax & Environment, President Green Budget Europe and Professor of Environmental Global Governance, University of Roma Tor Vergata, Italy The current Covid-19 pandemic has shown us that once again that science is our best ally to face disease. In this book a scientific position is used to highlight global warming which is another big problem that must be attended urgently. Lets not wait until we are in the abyss to react as happened with Coronavirus, we can prevent it and do something before it is too late. Human survival depends on our actions and every second counts. -- Daniel Irwin Yacolca Estares, National University of San Marcos, Peru
