Mitigation

Question 1

International climate negotiations

Answer 1

• Mitigation of climate change: measures and commitments to reduce GHG emissions
• Adaptation to climate change
• Financing climate-related action: climate funds and the Sustainable Development Mechanisms

Question 2

Adaptation and mitigation

Answer 2

• Assessing and managing the risks of climate change
• Vulnerability to climate change: susceptibility to adverse impacts
• Hazard: potential occurrence of natural or human-induced events
• Exposure to climate change: presence in areas that could be affected

Question 3

Assessing and managing the risks of climate change

Answer 3

• Mitigation: human intervention to reduce sources or enhance sinks of greenhouse gases
• Social benefits and costs of mitigation: allocation of resources for social welfare
• Marginal cost of GHG mitigation: assessment of potential and costs of options

Question 4

Mitigation costs

Answer 4

• McKinsey report: almost 40% of abatement in the U.S. could be achieved at negative social cost
• Options with negative social costs: focus on high abatement potential and low social costs
• Need for intervention: green zone options pay back for society and individual/company, yellow zone options need policy intervention, red zone options require special circumstances

Question 5

Cost of mitigation

Answer 5

• Average annual investment needed in key sectors: around US$ 350 billion per year until 2029
• Consistent with 2-degree Celsius pathway: keeps CO2 equivalent concentration in 430-530 ppm range until 2100
