Who Is Responsible For Climate Change? – Who Needs To Fix It?

Kurzgesagt – In a Nutshell2 minutes read

Humans have released an enormous amount of carbon dioxide since the Industrial Revolution, leading to extreme consequences like heat waves and glacier melting. Wealthier countries are the main culprits, with the US, EU, and China historically responsible for the highest emissions.

Insights

  • Human activity since the Industrial Revolution has led to a significant increase in carbon dioxide emissions, with over 1.5 trillion tons released into the atmosphere, creating severe environmental consequences such as heat waves and glacier melting.
  • The distribution of carbon dioxide emissions is heavily skewed towards wealthier countries, with Asia, China, the USA, and the European Union being major contributors, showcasing a direct correlation between wealth and carbon footprint.

Global Carbon Emissions: Wealth and Impact

  • Since the Industrial Revolution, humans have released over 1.5 trillion tons of carbon dioxide into the Earth's atmosphere, with 37 billion tons emitted in 2019, 50% more than in 2000 and almost three times the amount from 50 years ago.
  • Combining all greenhouse gases, 51 billion tons of carbon dioxide equivalents are emitted annually, with 20 of the last 22 years being the hottest on record, leading to severe consequences like heat waves, glacier melting, and record low ice levels at the North Pole.
  • In 2017, Asia contributed over 50% of global carbon dioxide emissions, with China being the largest emitter at 27%, followed by the USA at 15% and the European Union at around 10%.
  • Historically, the US and EU have emitted the most carbon dioxide, with the US responsible for 25% of global historical emissions, followed by the EU at 22% and China at just under 13%.
  • Countries with the highest carbon dioxide emissions per person include Qatar, Trinidad and Tobago, Kuwait, and the United Arab Emirates, with Australians having a carbon footprint of 17 tons per year, triple the global average.
  • Wealthier countries are responsible for 86% of global emissions, with the average German emitting more than five times as much as the average Indian, highlighting the correlation between wealth and carbon footprint.
