1. Understanding Global Greenhouse Gas Emissions
Greenhouse gas (GHG) emissions are a critical factor in climate change, and understanding global trends is essential. According to recent data, global GHG emissions have seen significant changes over the past few decades. From 2005 to 2021, global GHG emissions increased by 24%, rising from 39,001 to 48,210 megatonnes of carbon dioxide equivalent (Mt CO2 eq). This increase underscores the growing challenge of mitigating climate change on a global scale.
Similarly, per capita global GHG emissions have also increased, albeit at a slower rate. Between 2005 and 2021, these emissions rose by 2.67%, from 5.99 to 6.15 tonnes of carbon dioxide equivalent (t CO2 eq). While the per capita increase is smaller than the total emissions increase, it still indicates a persistent upward trend that needs to be addressed.
1.1 Historical Trends in Global Emissions
Analyzing historical data provides valuable context to current emission levels. In the early 1990s, global emissions were around 30,708.31 Mt CO2 eq, with per capita emissions at 5.82 t CO2 eq per person. There was a notable low period between 1992 and 2002, with per capita emissions ranging from 5.53 to 5.64 t CO2 eq per person. This decrease was partly attributed to the economic slowdown in Eastern Europe and Central Asia following the fall of the USSR.
From 2003 to 2007, both total and per capita global GHG emissions saw a sharp increase, with total emissions rising by 18.3% and per capita emissions by 11.3%. This surge was largely driven by China’s rapid economic growth and increased manufacturing, heavily reliant on fossil fuels.
1.2 Impact of Economic Events and Global Agreements
Economic events and international agreements have significantly influenced global emission trends. The global financial crisis in 2008 led to an economic slowdown, reducing manufacturing and electricity demand, which in turn caused a decline in total and per capita emissions from 2008 to 2009.
The COVID-19 pandemic in 2020 brought about unprecedented confinement measures, leading to industrial slowdowns and reductions in trade and travel. This resulted in a 4.12% decrease in total GHG emissions and a 5.12% decrease in per capita emissions from 2019 to 2020. However, with the relaxation of these measures in 2021, total global emissions climbed above pre-pandemic levels, and per capita emissions nearly reached 2019 levels.
In 2015, Canada and 194 other countries signed the Paris Agreement, committing to limit the global average temperature rise to well below 2°C and pursue efforts to limit the increase to 1.5°C. As part of this agreement, Canada initially committed to reducing its GHG emissions by 30% below 2005 levels by 2030, and later increased this commitment to 40% to 45% below 2005 levels by 2030.
Reaching these goals requires significant changes in energy systems and land use worldwide, with varying efforts and costs for different countries. Canada is dedicated to implementing its strengthened climate plan, the 2030 Emissions Reduction Plan, to exceed its 2030 emissions reduction goal and achieve net-zero emissions by 2050.
2. Canada’s Greenhouse Gas Emissions Compared to Top Emitters
To understand Canada’s environmental impact, it’s crucial to compare its greenhouse gas emissions with those of other major emitting countries and regions. In 2021, the top emitters were:
- China: 13,438 Mt CO2 eq (27.9% of global GHG emissions)
- United States: 5,782.55 Mt CO2 eq
- India: 3,444.46 Mt CO2 eq
- European Union (27): 3,301.27 Mt CO2 eq
- Russian Federation: 2,507.34 Mt CO2 eq
In comparison, Canada’s total emissions reached 676 Mt CO2 eq, accounting for 1.4% of global GHG emissions, making it the 12th largest emitter worldwide.
2.1 Per Capita Emissions Comparison
While total emissions provide one perspective, per capita emissions offer insights into individual contributions to pollution. In 2021, Canada’s per capita emissions were among the highest, standing at 17.7 t CO2 eq per person. This was second only to Saudi Arabia among the top emitting countries and regions.
Here’s a comparison of per capita emissions for the top emitters:
- Saudi Arabia: 20.67 t CO2 eq per person
- Canada: 17.69 t CO2 eq per person
- Russian Federation: 17.48 t CO2 eq per person
- United States: 17.42 t CO2 eq per person
- Iran: 11.20 t CO2 eq per person
In contrast, countries like India and Indonesia had significantly lower per capita emissions, at 2.47 and 3.65 t CO2 eq per person, respectively.
2.2 Changes in Emissions Over Time
Examining changes in emissions between 2005 and 2021 reveals important trends. Canada’s total emissions decreased by 1.40%, from 686 to 677 Mt CO2 eq. This decrease is smaller compared to other developed countries like the United States, which saw a 14.2% decrease, and the European Union, which experienced a 22.6% decrease.
Canada’s per capita emissions also decreased by 16.9% since 2005. While this is a positive trend, it is less significant than the decreases seen in the United States (23.6%) and the European Union (24.6%).
The expected rapid increase in emissions from developing and emerging economies, such as China (86.9% increase from 2005 to 2021) and India (75.1% increase), will likely continue to shift the distribution of global emissions. This highlights the need for international cooperation and sustainable development strategies to mitigate climate change effectively.
