Mitigation of Global Climate Change
Review of last lecture Cradles of civilization. Were the ancient people stupid? Ancient view of nature Industry revolution: positive effects and negative effects Vision: environmental protection and enjoy the bare necessities

Observed change of greenhouse gases Global atmospheric concentrations of CO 2 and CH 4 have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values determined from ice core measurements spanning the last 650,000 years!
GHG Emissions by Sector
Greenhouse gas emissions per capita The developed countries and developing countries contribute almost equally to the emissions of GHGs.
Mitigation of global climate change
Video: Climate Change 2014: Mitigation of Climate Change
International: Kyoto protocol Negotiated in Commits parties to internationally binding emission reduction targets. “Common but differentiated responsibilities” –Specific reduction targets for developed countries –Measures to slow the growth of emissions in developing countries Non-parties: –Canada –USA –Andorra –South Sudan –Palestine –Vatican City
Others Copenhagen Accord (2009) Not legally-binding Attempts to limit global warming to 2°C above pre-industrial temps Durban Platform for Enhanced Action (2011) Agreement to conclude new treaty by 2015 EU and other member countries agree to emissions cuts under Kyoto Protocol
Promises Increased understanding of climate change phenomena: – IPCC 5 th Assessment Report Emissions curbing: –Many Kyoto Protocol signatories on track to meet targets –Brazil, China, India
International: Progress Recent progress –EU –China and U.S. agreement Challenges
Principles: Sustainability Human rights and dignity Accountability Efficiency Investment in the future Business: Green Economy Six main components: Renewable energy, Green buildings, Sustainable transportation, Water management, Waste management, Land management
