Mitigation Strategies for Climate Change

Active learning works for this topic because students need to weigh complex, real-world trade-offs between different strategies. Debates and simulations let them grapple with uncertainty while case studies help them connect global agreements to local actions. This approach builds critical thinking about policy effectiveness and technical feasibility.

Activity 01

• Think-Pair-Share
• 45 min · Pairs

Debate Pairs: Renewables vs Carbon Capture

Pair students to research one strategy: renewables or carbon capture. Each pair prepares pros, cons, and evidence from sources like Singapore's EMA reports. They debate in class, with audience voting on most convincing argument.

Compare different approaches to reducing carbon emissions (e.g., renewable energy, carbon capture).

Facilitation Tip

During the debate pairs activity, provide students with a brief fact sheet comparing costs and scalability of renewables versus carbon capture so arguments remain grounded in data.

What to look for

Facilitate a class debate: 'Resolved, that international agreements like the Paris Agreement are more effective than national policies in mitigating climate change.' Assign students roles as representatives from different countries or as climate scientists to present evidence for their arguments.

Case Study Groups: Paris Agreement Analysis

Divide class into small groups, assign sections of the Paris Agreement text. Groups identify successes, challenges, and Singapore's Nationally Determined Contributions. Present findings on posters, followed by whole-class discussion.

Assess the challenges and successes of international climate agreements like the Paris Agreement.

Facilitation Tip

For the Paris Agreement analysis case study, assign each group a different country’s pledge and timeline so the class can collectively compare progress across diverse contexts.

What to look for

Present students with a short case study on Singapore's Green Plan 2030. Ask them to identify two specific mitigation strategies mentioned and briefly explain how each strategy aims to reduce greenhouse gas emissions.

Policy Simulation: Model UN Climate Talks

Assign countries or roles in a simulated negotiation. Students propose emission targets and mitigation plans, negotiate compromises. Conclude with a class vote on a joint agreement.

Justify the importance of transitioning to a low-carbon economy.

Facilitation Tip

In the Model UN simulation, assign roles with conflicting interests (e.g., fossil fuel dependent nations versus island states) to force students to negotiate realistic compromises.

What to look for

On an exit ticket, ask students to list one advantage and one disadvantage of relying on renewable energy sources compared to carbon capture technology. They should provide a brief justification for each point.

Activity 04

• 30 min · Individual

Action Plan Individuals: Local Mitigation

Students assess their school's carbon footprint, propose 3-5 mitigation steps like LED lighting or recycling drives. Share plans in a gallery walk for peer feedback.

Compare different approaches to reducing carbon emissions (e.g., renewable energy, carbon capture).

Facilitation Tip

When students draft their local mitigation action plans, require them to include at least one measurable target and one local stakeholder they would need to engage.

What to look for

Facilitate a class debate: 'Resolved, that international agreements like the Paris Agreement are more effective than national policies in mitigating climate change.' Assign students roles as representatives from different countries or as climate scientists to present evidence for their arguments.

A few notes on teaching this unit

Teach this topic by starting with concrete examples students can see in their own communities, then layering in global systems. Use clear comparisons like Singapore’s solar goals versus its land constraints to anchor abstract concepts. Avoid overwhelming students with too many policy details at once; focus on how strategies interact rather than memorizing all frameworks. Research shows students grasp mitigation best when they experience its trade-offs firsthand through role-play and data analysis.

Successful learning looks like students distinguishing between mitigation strategies, explaining how tools like carbon pricing or solar farms reduce emissions, and recognizing both the power and limits of international agreements. They should justify choices with evidence and adapt their reasoning as new data emerges.

Watch Out for These Misconceptions

• During the Paris Agreement analysis case study, watch for students assuming international agreements alone will solve climate change.

  Use the group case studies to redirect students toward the Paris Agreement’s reliance on national pledges like Singapore’s Green Plan. Have groups map how each country’s specific policies contribute to the global target, making it clear that agreements are frameworks, not solutions.

• During the debate pairs activity, watch for students assuming renewable energy works equally well everywhere.

  Use the mapping and peer teaching in this activity to highlight geographic constraints. Provide Singapore-specific data on solar versus wind potential and ask pairs to adjust their arguments based on these local realities.

• During the Model UN simulation, watch for students assuming carbon capture can eliminate all emissions.

  Use the simulation’s negotiation process to redirect students toward the technical and economic limits of carbon capture. Have them present data on capture rates and costs, forcing them to confront the technology’s partial effectiveness.
