How can individuals and corporations manage and reduce their carbon contributions?

By 2050, the world must double its energy and food supply to meet demand generated in large part by a growing increasingly prosperous population. We need to act now to balance increased production and consumption with the urgent steps necessary to monitor, manage, and mitigate climate change and its associated ecological and environmental risks.The Solve community aims to help fill some of the acute gaps in thinking, implementation, and discovery which exist in the effort to solve the world’s most pressing challenges. To help jumpstart additive solutions to manage our global emissions crisis, the SOLVE community will seek to generate and implement solutions to:

  • Generate, test and deploy carbon removal technologies that could be deployed by individuals and/or corporations, at point or at scale.
  • Suggest implementable ‘bottom-up’ carbon pricing approaches for communities and businesses.
  • Propose large-scale individual-level and business-level solutions to significantly reduce emissions.

NOTE: Solutions which address only one or several of these areas are welcome.
