||‘Climate Justice’ (CJ) is the name of the new movement that best fuses a variety of progressive political-economic and political-ecological currents to combat the most serious threat humanity and most other species face in the 21st century. The time is opportune to dissect knowledge production and resistance formation against hegemonic climate policy making. One reason is the ongoing fracturing of elite power – including acquiescence by large environmental non-governmental organizations (NGOs) - in era of extreme global state-failure and market-failure. The inability of global elite actors to solve major environmental, geopolitical, social and economic problems puts added emphasis on the need for a CJ philosophy and ideology, principles, strategies and tactics. One challenge along that route is to establish the most appropriate CJ narratives (since a few are contraindicative to core CJ traditions), what gaps exist in potential CJ constituencies, and which alliances are moving CJ politics forward. This can be done, in part, through case studies that illustrate approaches to climate injustice spanning campaigns and institutional critique. But it is through positive messaging and proactive traditions of CJ that the movement will gain most momentum for the crucial period ahead.
