Staying within Sustainable Limits: Advancing leadership of the private sector and cities To demonstrate a path for companies and cities to adopt robust science-based targets to sustain Earthâ€™s biodiversity and land systems, and influence all of society to safeguard our global commons. Note: Disbursement data provided is cumulative and covers disbursement made by the project Agency. Together, the Earth Commission, the Science-Based Targets Network and its associated issue hubs and Earth HQ, the communications and mobilization efforts will conform a Global Commons Alliance. The Alliance brings together powerful leadership, technology, science, innovation, and communication to positively transform the world’s economic systems and protect the global commons. This Alliance will be branded with its makeup and targets marketed within planetary science circles as well as among corporations and cities. The Global Commons Alliance is an unprecedented international network that aims to ensure our planet remains habitable.     The Alliance will become the recognized scientifically based source for measurable targets that corporations, cities, and even countries can adopt and publicly announce. By developing these entity specific targets, the number of globally recognized companies and large (500K+ inhabitant) cities adopting targets for land and biodiversity will increase. The adoption of these targets will spur others to take similar action with the combined effort slowing habitat loss and ecosystem degradation while protecting biodiversity and mitigating climate change. The uptake of biodiversity and land targets developed within the timeframe of this project will contribute to the development and spur the adoption of entity-specific targets for oceans and freshwater and further targets for climate. These leadership actions undertaken by companies and cities within the timeframe of this two-year project influence supply chains globally, and private sector support, national governments will be encouraged to raise their level of ambition for making and delivering on these conservation commitments. The development of these targets will provide a much-needed tool for helping companies, cities, and nations understand what needs to be done to ensure that critical Earth systems are maintained, and the measures that they must undertake to do so.     In summary, this project is harnessing the world’s greatest leadership, technology, science, innovation, and communication to positively transform our global economic systems and protect the global commons. According to the latest science, the drain onthe global commons,largely due to the structure and pace of the global economy, is overwhelming critical planetary life-support systems. The system isout of balance.  Science can show us how much and how quickly we need to reduce our impact on our climate, freshwater, biodiversity, land and oceans. Scientists can define a “north star” that we must reach in order to rebalance planetary systems. Government and business leaders need to use this as a guide to ensure the required transformation of global economic systems. We need to mobilize everyone at every level - so they can play their part in reaching this north star.
