Global scenarios of greenhouse gas emissions reduction: the 2°C target and less stringent goals.
Olivier Dessens, Gabrial Anandarajah
This work examines the feasibility of limiting the average global temperature rise, using the latest version of the TIAM-UCL global integrated assessment model. We examine the window of opportunity for continuing to increase emissions while still limiting the average temperature rise between 2 and 3°C with different emission reduction rates. Mitigation costs and efforts between high-, middle- and low-income regions are also discussed.

Increasing the mitigation potential of agricultural non-CO2
emissions and supporting measures to realize this potential
could make a substantial contribution to meeting the 2°C

– Findings on Multi-model Comparison in ICA-RUS Project
Shunsuke Mori (Tokyo Univ. of Sci), Toyoaki Washida(Sofia Univ), Atsushi Kurosawa(IAE) and Toshihiko Masui(NIES)
ICA-RUS project conducted by NIES aims at providing risk management strategies under SSP-RCP based scenarios and the knowledge on climate impacts and mitigation options. Four IAMs participate in the assessment procedure of ICA-RUS. We found the economic losses by stringent climate policy is significantly influenced by the final energy conservation assumptions while food production and land-use do not vary significantly.

Other findings and conclusion: (1) CCS as well as BECCS will be essential to achieve the stringent climate target. (2) Industry structure in Asia and Africa will change depending on the climate policies. (3) The models show only small changes in the crop production and land-use patterns. Future uncertainties on technologies, policies and societal issues are the further issues to be considered.
GDP loss is significantly mitigated by the final energy conservation
Complementing carbon prices with technology policies to keep climate targets within reach
1. What is the impact of choosing alternative policy instruments until 2030?
• Support for low-carbon
• Regulating the dirtiest
• Pricing carbon – carbon tax or cap-and-trade
2. How do policy instruments interact?
3. Can a realistic policy mix lay the ground for long-term achievement of the 2°C?
• Dynamic effects
• Both short-term emissions and long-term economic implications
