    • Notable emissions from residential and commercial buildings.
    • Shift to more efficient systems and electric heat pumps necessary.
• Types of mitigations and adaptations required
  • Electricity Generation (27% of Emissions):
    • Renewable Energy: Increase investment in solar, wind, hydroelectric, and geothermal energy.
    • Nuclear Energy: Consider safe and modern nuclear technologies as a low-emission alternative.
    • Grid Modernization: Upgrade power grids to efficiently distribute renewable energy and integrate smart grid technologies.
    • Energy Storage: Develop better battery technologies and other energy storage methods to manage the intermittency of renewable sources.
  • Transportation (16% of Emissions):
    • Electrification of Vehicles: Expand the use of electric cars, buses, and trucks. Implement incentives for electric vehicle (EV) purchases and build EV charging infrastructure.
    • Public Transportation: Improve and expand public transit systems to reduce reliance on individual vehicles.
    • Alternative Fuels: Develop and use biofuels and hydrogen fuels for sectors where electrification is challenging, like aviation and shipping.
    • Efficiency Improvements: Enhance fuel efficiency standards for vehicles and encourage the use of lighter materials and aerodynamic designs.
  • Manufacturing – Steel and Plastic (31% of Emissions):
    • Process Innovations: Implement new technologies that reduce emissions in the production of materials like steel and cement.
    • Recycling and Reuse: Encourage circular economy practices to reduce the demand for new material production.
    • Carbon Capture and Storage (CCS): Use CCS technologies to capture emissions from industrial processes and store them underground.
  • Agriculture (19% of Emissions):
    • Sustainable Farming Practices: Promote agricultural methods that reduce emissions, such as precision farming and organic agriculture.
    • Methane Management: Implement strategies to reduce methane emissions from livestock, such as dietary changes and better manure management.
    • Land Use Management: Encourage practices like agroforestry and sustainable land management to increase carbon sequestration.
  • Heating and Cooling (7% of Emissions):
    • Energy Efficiency: Improve insulation and energy efficiency in buildings to reduce heating and cooling demands.
    • Heat Pumps: Promote the use of electric heat pumps, which are more efficient than traditional heating methods.
    • Smart Building Design: Utilize smart building technologies and passive solar design to minimize energy usage.
  • Cross-Sector Strategies:
    • Carbon Pricing: Implement carbon taxes or cap-and-trade systems to provide financial incentives for reducing emissions.
    • Research and Development: Invest in R&D for new technologies and innovations in energy, materials, and agriculture.
    • Education and Awareness: Increase public awareness and education on climate change and sustainable practices.
    • Policy and Regulation: Enact policies and regulations that support emission reduction across all sectors.
  • International Cooperation:
    • Global Agreements: Strengthen international agreements like the Paris Agreement to ensure global commitment and action.
    • Technology Transfer: Facilitate the transfer of clean technologies to developing countries.
    • Financial Support: Provide financial assistance to developing countries for climate mitigation and adaptation efforts.
  • Adaptation Measures:
    • Infrastructure Resilience: Upgrade infrastructure to withstand extreme weather events and sea-level rise.
    • Ecosystem Restoration: Restore and protect ecosystems like forests, wetlands, and mangroves for natural carbon sequestration and climate resilience.
    • Water Management: Implement strategies for sustainable water use and protection against droughts and floods.
    • Health and Emergency Preparedness: Enhance public health systems and emergency response capacities to deal with climate-related disasters.
• Understanding the Impact and Scale:
  • Analyzing Data and Statistics:
    • Evaluate contributions to global emissions of 51 billion tons.
    • Comprehend the power requirements and densities of different energy sources.
    • Assess the real-world impact of proposed changes on a global level.
