Systems transitions
How can we make the systems

How societal goals be
maximised while doing
1.5°C-consistent mitigation
and adaptation?
5. Most synergies by reducing demand for energy, materials and land
Robust synergies between
1.5C and …
• SDG 3 (health)
• SDG 7 (clean energy)
• SDG 11 (cities)
• SDG 12 (sustainable
cons & prod)
• SDG 14 (oceans)
Risks of trade-offs with
SDG 1 (poverty)
SDG 2 (hunger)
SDG 6 (water access)
SDG 7 (energy access)
6. How to maximize synergies ?
Act fast while anticipating long-term changes
To keep the possibility of choices in the future
Combine actions from different actors
Mobilizing all stakeholders operating at different scales
Think within structured strategies
Combinations of systemic, dynamic and context-specific actions
Coordinate actions
International cooperation is a critical enabler for the effectiveness and equity of the
transition

Presenting highlights of the report which was released on 8 October after six days and several nights of deliberations between the member governments of the IPCC. However, a few notes upfront about the IPCC:
IPCC is based on peer-reviewed literature. This is a quality check for the information in the report. But it is also a limitation as it means we cannot assess engineering studies,
Policy relevant and not policy prescriptive. So the IPCC is not telling governments what to do. We can provide factual information (like: if you want to stay below 1.5C, emissions will have to be net zero around 2050)
Scientific Climate Change panel of the UN. Member governments that determine which reports will be written and what the outline of the report is
I am sometimes asked whether the governments dictate what we write. The answer is: no. The report is written by the authors. It is reviewed in two rounds by experts and in one round by governments
There is one special thing and that is the Summary for Policymakers (SPM). This document cannot contradict the underlying report but governments agree on it by consensus, and different governments want to emphasise different elements. This turns into a negotiation in which the author’s role is to make sure the underlying report is not contradicted.
You could say that this means that governments are having too big of an influence on the messaging of the report. But it also makes the IPCC much more politically influential. Governments have more of a moral obligation to observe what the IPCC has indicated to them.
This report is even more special as it’s the first time that the parties to the Paris Agreement have asked the IPCC to write a report that will be used directly in their deliberations at the climate conference in december in Katowice in Poland. There countries will discuss whether the national plans are sufficient and whether they need ratcheting up.
