Question
The green shaded area represents the GHG emissions we can probably prevent by "conventional abatement technologies" (i.e., all efforts to reduce CO, emission sources). These include:
--- ### Decarbonizing Our Energy Supply: A Path to Net Zero Greenhouse Gas (GHG) Emissions #### Understanding the Chart The primary chart illustrates the projected trajectories of GHG emissions from now until the year 2110, under different scenarios and the impact of various mitigation and removal technologies. Here's a detailed breakdown: #### Graph Explanation - **X-Axis:** Represents the years from 2010 to 2110. - **Y-Axis:** Represents the GHG emissions measured in GtCO2e per year (Gigatonnes of CO2 equivalent per year). #### Key Elements: 1. **Yellow Line (Business as Usual):** Shows the GHG emissions if no significant changes or mitigation efforts are made. 2. **Red Line (Below 2°C):** Represents the target trajectory needed to limit global warming to less than 2°C by 2100. 3. **Green Shaded Area (Mitigated GHG Emissions):** Indicates the emissions that can be reduced by decarbonizing our energy supply using conventional abatement technologies. 4. **Beige Shaded Area:** Denotes the GHG emissions that are difficult to eliminate completely with current technologies, such as emissions from older houses with gas furnaces or livestock emissions. 5. **Blue Shaded Area (Negative Emissions):** Covers the required carbon removal from the atmosphere using negative emissions technologies to compensate for the beige shaded area and achieve the red line target. 6. **First Priority (Green Text):** Emphasizes the importance of decarbonizing our energy supply as a primary step. 7. **Supplementary Reduction (Blue Text):** Suggests supplementing decarbonization efforts with negative emissions technologies. #### Technology Examples On the right side of the chart, there are examples of associated technologies depicted, which are crucial for achieving these targets: - **Conventional Abatement Technologies:** Solar panels, wind turbines, energy-efficient lighting, etc. - **Emitting Technologies:** Those that currently contribute to emissions, such as fossil fuel-powered machinery. - **Carbon Removal Technologies:** Innovative solutions aimed at removing CO2 directly from the atmosphere. ### Key Message To achieve net zero GHG emissions by approximately 2090, indicated by the red line, it is essential to actively remove CO2 from the atmosphere using carbon removal technologies (depicted in the blue shaded area). This effort, combined with decarbonizing the energy supply and addressing

### Understanding Conventional Abatement Technologies for Reducing GHG Emissions The green shaded area represents the GHG (Greenhouse Gas) emissions we can probably prevent by "conventional abatement technologies" (i.e., all efforts to reduce CO₂ emission sources). These technologies and efforts primarily include: - **Renewable energy electricity expansion**: Increasing the use of renewable energy sources such as wind, solar, and hydroelectric power to generate electricity. - **Coal phase out**: Gradually discontinuing the use of coal as an energy source in favor of cleaner alternatives. - **Decarbonizing transport**: Implementing measures to reduce carbon emissions from transportation, including the promotion of electric vehicles and improvements in fuel efficiency. - **Decarbonizing industry**: Introducing methods and technologies to reduce carbon emissions from industrial processes. In the image, a multiple-choice question is provided with the following answer options: 1. Renewable energy electricity expansion 2. Coal phase out 3. Decarbonizing transport 4. Decarbonizing industry 5. All of the above The correct answer, as indicated, is **Decarbonizing industry**. However, all of the mentioned options contribute to the overall reduction of CO₂ emissions.
