Study Notes
Global CO2 Emissions
- The United States has emitted more CO2 than any other country, accounting for 25% of historical emissions – twice that of China.
- The European Union (EU-27) is also a significant historical contributor, at 22%.
- Many current large emitters, like India and Brazil, are not major historical contributors.
- Africa's contribution is minimal, due to historically low per capita emissions.
Developing Countries and Climate Change Vulnerability
- Developing countries face more severe climate impacts, like frequent floods and droughts.
- These countries have a larger portion of their economies tied to climate-sensitive sectors.
- They have less capacity to adapt due to lack of financial, institutional, and technological resources.
- Climate change disproportionately affects the poorest, exacerbating inequalities in health, food, and water access.
Integrated Climate Change and Sustainable Development
- A former viewpoint separated climate change and development as distinct issues.
- A more modern view emphasizes integrating climate change goals into sustainable development strategies.
- These strategies now aim to manage the relationship between both simultaneously rather than as separate considerations.
Expected Increase in GHG Emissions
- In 1995, developing countries accounted for 27% of global GHG emissions, while developed countries made up 73%.
- Projections suggest a significant shift in 2035, with developing countries' share increasing to 50% and developed countries remaining approximately 50%.
- China's share is significant and expected to increase further.
Actions to Reach Net-Zero Emissions by 2030
- Increase solar and wind capacity dramatically, to 500 gigawatts.
- Eliminate coal-fired electricity generation.
- Maintain current natural gas generating capacity for reliability.
- Increase sales of zero-emission vehicles.
- Increase sales of building heat pumps.
- Develop and deploy carbon capture and sequestration technologies.
- Build carbon dioxide and hydrogen gas pipelines for transportation.
Global Greenhouse Gas Emissions by Sector (2016)
- Energy is the largest contributor to global greenhouse gases, comprising 73.2% of emissions.
- Energy consumption across various sectors (industry, buildings, and transport) accounts for most energy usage.
- Agriculture, Forestry, and Land Use (AFOLU) contribute 18.4%, encompassing activities like deforestation and crop burning.
Direct Industrial Processes
- Cement production releases significant amounts of carbon dioxide.
- Chemical and petrochemical processes are sources of various greenhouse gases.
Waste
- Wastewater and landfills generate methane and nitrous oxide as organic matter decomposes in low-oxygen environments.
