Climate Change Mitigation Strategies

Active learning works for climate change mitigation because students grapple with real-world trade-offs, not abstract facts. When they analyze policies, model technologies, and audit their school, they see how strategies connect to emissions, costs, and daily life, making abstract concepts concrete and meaningful.

Activity 01

• Jigsaw
• 50 min · Small Groups

Jigsaw: Scales of Mitigation

Divide class into expert groups on local, national, and global strategies; each researches one using provided resources like IPCC summaries. Groups then mix to teach peers and compare effectiveness. Conclude with a whole-class chart of pros, cons, and Canadian examples.

Explain why international cooperation on climate change is so difficult to achieve.

Facilitation Tip

During the Jigsaw: Scales of Mitigation, assign each expert group a unique scale (local, provincial, national, global) and require them to prepare a 60-second summary of their key takeaway to share with home groups.

What to look for

Pose the question: 'Given the diverse economic and political interests of nations, what are the primary obstacles to achieving effective international cooperation on climate change mitigation?' Facilitate a class debate, encouraging students to cite specific examples from historical climate agreements.

Activity 02

• Project-Based Learning
• 45 min · Small Groups

Role-Play: Climate Negotiations

Assign roles as country representatives facing emission targets; students negotiate compromises based on real Paris Accord data. Use timers for rounds and vote on agreements. Debrief on why cooperation fails, linking to equity issues.

Analyze the role of technology in sequestering carbon from the atmosphere.

Facilitation Tip

In the Role-Play: Climate Negotiations, give students a one-page brief with their assigned country’s priorities and constraints to ensure debates stay grounded in real-world constraints.

What to look for

Provide students with a short case study of a specific mitigation strategy (e.g., Ontario's former cap-and-trade program). Ask them to identify two potential benefits and two potential drawbacks of this strategy, considering both environmental and socio-economic factors.

Activity 03

• Project-Based Learning
• 60 min · Pairs

Carbon Audit: School Site

Pairs measure school energy use via meters or bills, calculate footprint with online tools, and propose three mitigations like LED retrofits. Present findings to class for vote on top ideas.

Evaluate the effectiveness of different mitigation strategies at various scales.

Facilitation Tip

For the Carbon Audit: School Site, provide a simple spreadsheet template for data collection to help students focus on analysis rather than formatting.

What to look for

On an index card, have students write the definition of 'carbon sequestration' in their own words and then list one natural and one technological method used for this purpose.

Activity 04

• Project-Based Learning
• 40 min · Small Groups

Model: Sequestration Tech

Small groups build simple carbon capture models using bottles, CO2 sources, and absorbers like limewater. Test variables, record data, and discuss scalability for real tech like direct air capture.

Explain why international cooperation on climate change is so difficult to achieve.

Facilitation Tip

With the Model: Sequestration Tech, set a clear time limit (10 minutes) for the modeling phase to avoid overcomplicating the activity and to encourage iterative testing and improvement.

Facilitate a class debate, encouraging students to cite specific examples from historical climate agreements.

A few notes on teaching this unit

Experienced teachers approach this topic by balancing urgency with nuance. They avoid simplistic solutions by using activities that reveal trade-offs, such as cost vs. impact or speed vs. scalability. Research suggests students retain concepts better when they work with real data from their own context, so local audits and policy case studies are essential. Avoid overloading with technical jargon; instead, connect terms to tangible examples like Ontario’s GreenON program or school recycling bins.

Successful learning looks like students using evidence to evaluate mitigation strategies, not just recite them. They should compare local and global approaches, explain why scale matters, and connect their findings to policy or personal action, showing they understand both the science and the human systems behind mitigation.

Watch Out for These Misconceptions

• During Jigsaw: Scales of Mitigation, watch for statements that assume all strategies work equally at every scale.

  Use the jigsaw’s expert groups to require students to present one example of why their scale’s strategies face unique challenges, such as local zoning laws or national political gridlock, and have home groups compare these across scales.

• During Model: Sequestration Tech, watch for students assuming technology alone can solve climate change without policy or behavior changes.

  Have students test their models by adding a policy constraint (e.g., a carbon tax) or a behavior change (e.g., reduced energy demand) and observe how the technology’s effectiveness shifts.

• During Carbon Audit: School Site, watch for students believing international agreements make local actions irrelevant.

  Guide students to calculate their school’s emissions and compare them to Canada’s national targets, then ask them to propose a local action that would contribute meaningfully to those targets.
