  • Budget: a global budget for emissions of industrial greenhouse gases. 'Yes*' means that the importance of a global budget is given particular emphasis.
  • U or D: "Upstream" or "downstream" controls?
  • Funds: Proposes mechanisms to raise funds for mitigation and adaptation?
  • GHG scope: The range of greenhouse gases that are controlled.
