UN Climate Change Conference 2017 (COP23)

Two years after the historic Paris Agreement on climate change, this year's UN climate conference will focus on the way forward for implementation. IIASA experts bring the latest research on how to reach the ambitious targets set in 2015. 



The Paris Agreement aims to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels” and pursue efforts “to limit the temperature increase to 1.5°C above pre-industrial levels.” In 2016, global average surface temperature reached about 1.1°C above pre-industrial levels making it the warmest year on record in all major global surface temperature datasets. 

At COP23, the annual climate negotiation conference of the United Nations Framework Convention on Climate Change (UNFCCC), IIASA researchers will participate in several side events aimed at providing their expertise to policymakers. COP23 website.

Climate Action and Human Wellbeing at a Crossroads:
Historical Transformation or Backlash?

Energy Policy Trade-offs within the Broader Sustainable Development Challenge

November 10 | 13:15-14:45 - The SDG 7 on Energy plays a key role in the achievement of all other Sustainable Development Goals (SDGs). Access to safe, clean and affordable energy is a necessary condition to reduce poverty and to support human development. However, the manner and the extent that energy resources are exploited can adversely impact the climate, land-use, water sectors and other goals. This system behavior is characteristic of how optimization of policy goals in one area can create detrimental impacts in other areas.

IIASA speaker: Simon Langan

The Water-Food-Energy NEXUS

November 11 | 12:00-13:30 - Increasing food, energy, water security and sustainability is essential to the Sustainable Development Goals (SDGs) and the Paris Climate Agreement. Using the ‘Nexus approach’- the interconnections between energy, water, food, land and climate resources – enables policy-makers to identify and address trade-offs and exploit synergies, leading to more efficient resource use. Climate action will benefit from a Nexus approach as it leads to better, more realistic modelling outcomes and more effective policies. The panel will focus on examples of climate action in the domains of energy and food and linkages to land use policies. 

IIASA speaker: Simon Langan

Climate risk management and transformation: working towards solutions for dealing with risks 'beyond adaptation' and the Loss and Damage debate

November 12 |10.45-11.45 - Objectives: Improved insight into policy options and implementation opportunities for dealing with risks beyond adaptation and the Loss and Damage debate; Improved understanding of various perspectives on the Loss and Damage debate, incl. overlap and differences with adaptation and disaster risk management; Understanding interventions taken to address the limits to adaptation.
