The objective of this guide is to provide a brief synopsis of the reasons for which a green economic recovery is essential for a more equitable and environmentally sound future and to guide parliamentarians on supporting this endeavour. The guide provides an overview of the science, illustrating the severity of the climate and environmental crisis, as well as the social, environmental, and economic benefits of investing in a green future. It also references available resources, tools, and international frameworks that can be used to guide strategies and identify opportunities for sustainable investment. Due to the brevity of this publication, readers are highly encouraged to consult the cited references for more in-depth analyses.
