We have has conducted extensive research on state and local decarbonization efforts, which can play a crucial role in addressing the impacts of climate change. Our work has reviewed initiatives such as setting renewable energy targets, implementing energy efficiency measures, promoting sustainable transportation systems, and adopting stringent building codes. We believe that State and local decarbonization initiatives serve as powerful examples and catalysts for broader climate action, inspiring other regions to follow suit and accelerate the transition to a sustainable future.
