1This chapter takes sustainable
development as the starting point
andfocusforanalysisofbidirectional interplay with climate
actions in a 1.5°C warmer world2

Limiting global warming to 1.5°C rather
than 2°C would make it markedly easier toachieve many aspects of sustainable
development, with greater potential toeradicate poverty and reduce inequalities3• Impact avoided with lower temperature lessens therisks of poor people to experience food and water
insecurity, adverse health impacts, and economiclosses, particularly in regions that already facedevelopment challenges. Makes it easier to achieve
SDGs• However, warming of 1.5°C is not considered ‘safe’ formost nations, communities, ecosystems, sectors andposes significant risks to natural and human systems ascompared to current warming of 1°C
4Compared to current conditions, 1.5°C of
global warming would none the less poseheightened risks toEradicating poverty, reducing
inequalities, ensuring human and ecosystemwell-being

Prioritisation of sustainable
development and meeting the SDGs is
consistent with efforts to adapt toclimate change

6Synergies between adaptation
strategies and sustainable development
are significant

7

Pursuing
place-specificadaptation
pathways toward a 1.5°C warmer world has
the potential for significant positive
outcomes for well-being, in countries at alllevels of development

8

The deployment of mitigation options consistent with
1.5°C pathways leads to multiple synergies across a
range of sustainable development dimensions.
At the same time, the rapid pace and magnitude ofchange that would be required to limit warming to
1.5°C, if not carefully managed, would lead to tradeoffs with some sustainable development dimensions

9

Appropriately designed mitigation actions to reduceenergy demand can advance multiple SDGs
simultaneously. Pathways compatible with 1.5°Cthat feature low energy demand show the mostpronounced synergies and the lowest number of
trade-offs with respect to sustainable development
and the SDGs

10

The impacts of Carbon Dioxide
Removal (CDR) options on SDGs
depend on the type of options and thescale of deployment

11

Appropriate design andimplementation requires considering
local people’s needs, biodiversity, andother sustainable development
dimensions

12

The design of the mitigation portfolios and policy
instruments to limit warming to 1.5°C will largely
determine the overall synergies and trade-offs
between mitigation and sustainable development.
Redistributive policies that shield the poor andvulnerable can resolve trade-offs for a range ofSDGs

13

Mitigation measures consistent with 1.5°C
create high risks for sustainable development
in countries with high dependency on fossil
fuels for revenue and employment
generation

14

Risks are caused by the reduction of global
demand affecting mining activity, export
revenues from fossil fuel sector, rapid
decrease in carbon intensity
Targetedpolicies
that
promote diversification of the economy and theenergy sector could ease this transition

15

Limiting warming to 1.5°C would require allcountries and non-state actors to strengthen theircontributions without delay. This could be achieved
through sharing of efforts based on bolder and morecommitted cooperation, with support for those withthe least capacity to adapt, mitigate, and transform16

Addressing challenges and widening opportunities
between and within countries and communities
would be necessary to achieve sustainable
development and limit warming to 1.5°C, without
making the poor and disadvantaged worse off17Fundamental societal and systemic changes
to achieve sustainable development,
eradicate poverty and reduce inequalities
while limiting warming to 1.5°C would
require a set of institutional, social, cultural,economic, technological conditions to be met18• Coordination & monitoring of policy actions• External funding and technology transfer better withdue consideration to recipients’ context-specificneeds• Inclusive processes to ensure participation,transparency, capacity building, and iterative social
learning• Attention to power asymmetries and unequal
opportunities for development to benefit allpopulations• Re-examining individual and collective values could
help spur urgent, ambitious, and cooperativechange.
