Global Warming of 1.5°C
An IPCC special report on the impacts of global warming of 1.5°C above pre-industrial
levels and related global greenhouse gas emission pathways, in the context of
strengthening the global response to the threat of climate change, sustainable
development, and efforts to eradicate poverty.

2. Strengthening the Global Response in the
Context of Sustainable Development

3. 2
Climate mitigation measures can generate
positive impacts (synergies) and negative
impacts (trade offs) with developmental
actions.
Knowing those is important for making policy
choices
Both Positive and Negative Links

4. 2
Energy demand (transport, buildings, industry)
sector : behaviourial responses, fuel switching,
energy use efficiency, (carbon capture and storage-
CCS/U)
Energy Supply sector : Biomass-non biomass
renewables, nuclear, CCS-bio energy, CCS-fossil
Land Sector: sustainable diets, reduced food waste,
soil carbon sequestration, livestock manure
management, reduce deforestation, afforestation,
reforestation, responsible forest product sourcing
Mitigation actions

12. 2
For energy demand sectors most of the
measures facilitate achievement of goals
But model pathways that rely more on land
based measures like bioenergy, afforestation if
poorly managed can compete with food
security
Redistributive policies across sectors and
populations can resolve trade offs
