Blockadia and carbon emissions Scholars have posited that Blockadia movements are plausibly an avenue for global
carbon dioxide emission reduction. While international negotiations have resulted in an agreement for promised reduction of 20 billion tons of carbon dioxide per year, scholar
Joan Martínez-Alier argues that bottom-up grassroots movements like Blockadia will prove more effective in spurring on reduction of emissions than top-down international policy. This has been cited as a driving force for Blockadia and LFFU movements to fight corporations involved in projects that produce extreme levels of carbon emissions. In one particular example, scholars have presented evidence that collusion between the
Canadian government and multi-national corporations to develop of the
Alberta Tar Sands is an example of state-corporate crime, because
tar sands oil is especially resource intensive to extract, refine, and transport. Tar sands contribute disproportionately to carbon emissions. These scholars say that tar sands' contributions to global warming and ecological destruction constitute an assault on humans and other species, including local residents and
First Nations communities.
Differences with mainstream environmentalism Blockadia's divergence from mainstream environmentalism took place in the context of resistance to
tar sands development with this understanding of tar sands' contribution to the
climate crisis. In addition to its adoption of confrontational tactics, Blockadia movements differ from mainstream environmentalism by integrating
environmental justice concerns and building diverse
grassroots coalitions, where environmentalism had previously emphasized
NIMBY campaigns, celebrity environmentalism, and advocacy for legislative action. Blockadia participants tend to be more concerned with legitimacy than legality, and are responding to a perceived planetary emergency. Blockadia movements have formed unexpected alliances between grassroots groups responding to perceived local threats. Blockadia relies primarily on
decentralised leadership and frequently organises actions through social media. Martinez Alier and other scholars describe Blockadia as a network of
glocal campaigns with a deeply democratic approach: participants are aware of the connections between local injustice and the global climate crisis. Blockadia's strategies include legal approaches asserting the
right to a healthy environment and protecting local means of
subsistence. == History ==
