Scaling up actionable climate knowledge

To address climate-driven crises, we need actionable climate knowledge to inform decision-making and support problem solving. Although the science of actionable knowledge is rapidly evolving, less is known about how and why actionable climate knowledge scales up and with what outcomes. We advance three outcome-driven pathways to scale up actionable climate knowledge: 1) broadening participation by increasing the diversity and number of actors involved in actionable climate knowledge coproduction; 2) diffusing actionable climate knowledge uptake among actors not originally involved in its coproduction, and 3) aggregating impact by coproducing actionable climate knowledge with influential actors, such as practitioners and policy-makers, whose decisions affect many others. These pathways can intersect, complement, interact, and tradeoff with each other. Understanding how these pathways work, evolve, and change is critical if we want to better inform the production and scaling of climate actionable knowledge to solve climate problems.
