Does unionization reduce CO₂ emissions in Canada?

Area of Science:

• Environmental economics
• Labor economics
• Climate change studies

Background:

• The relationship between labor unionization and climate change outcomes is not well-established, with mixed anecdotal evidence.
• Limited empirical research exists on the impact of unions on environmental performance, particularly CO2 emissions.
• Existing literature shows unions sometimes support climate protection and other times prioritize job preservation over emission reduction.

Purpose of the Study:

• To investigate the impact of unionization on carbon dioxide (CO2) emissions in Canada.
• To address the gap in empirical literature concerning union-climate dynamics.
• To control for key economic factors such as energy consumption, unemployment, and GDP per capita.

Main Methods:

• Employed cointegration techniques, specifically Johansen methods and autoregressive distributed lag (ARDL) models.
• Utilized a comprehensive dataset spanning from 1969 to 2016 for Canada.
• Analyzed the relationship between unionization rates and CO2 emissions while accounting for control variables.

Main Results:

• A statistically significant negative relationship was found between unionization and CO2 emissions.
• On average, a 1% increase in unionization was associated with an approximate 0.25% reduction in CO2 emissions.
• This study provides the first empirical evidence on the union-climate nexus in the Canadian context.

Conclusions:

• Unionization appears to have a mitigating effect on CO2 emissions in Canada.
• Policy recommendations include incentivizing industries to integrate climate measures through collective bargaining processes.
• Findings suggest that labor unions can be a significant factor in achieving climate policy objectives.
