UNFCCC Article 3.1
What is done to protect the climate system, and how it is carried out
should be equitable and in accordance with CBDR/RC.

What?
Distributive Justice
european capacity building initiative
ecbi
[Art. 3.1] The Parties should protect the climate system for the
benefit of present and future generations of humankind,
on the basis of equity and in accordance with their
common but differentiated responsibilities and
respective capabilities. Accordingly, the developed
country Parties should take the lead in combating
climate change and the adverse effects thereof.
Distributive Justice: Definitions
Distributive Justice
Principles of distributive justice are normative principles designed to guide the allocation of the
benefits and burdens of economic activity.
http://plato.stanford.edu/entries/justice-distributive/
As far as distributive justice definition is concerned, the term distributive justice is referred to as equal
distribution of resources that are scarce among all demographics and population sectors, no matter what
socioeconomic group they belong.

Distributive Justice: the justice that is concerned with the apportionment of
privileges, duties, and goods in consonance with the merits of the individual
and in the best interest of society
Two Paradigms
− one Methodology
‘This, then, is what the just is – the proportional;
the unjust is what violates the proportion.’
Aristotle, Nicomachean Ethics, Book V
II. “Burden sharing”:
Sharing costs/benefits of the manner in which the climate system is being protected.
• Proposed Distributive Justice Principles: Polluter Pays (and Solidarity)
• Aristotelian parameters: responsibility levels (and capability levels)
NB:
• Allocations of emissions permits/space will impose (direct) costs and benefits, and
they will have to be treated as just, if the allocations are deemed to be just.
• Burden sharing covers more issues than mitigation (e.g. adaptation and impact
burdens) that will have to be addressed.

I. “Resource Allocation”:
Sharing limited emission permits/space between countries
• Proposed Distributive Justice Principle: Egalitarian (‘per capita’)
• Aristotelian parameter: population size
What differentiation?
United States Input to the Negotiating Text for Consideration at the 6th Session of the AWG-LCA
Section 1 – Mitigation : Article 2
1. Developed country Parties:
a. For each such Party, Appendix 1 includes quantitative emissions reductions/removals in the 2020/[ ]
timeframe, in conformity with domestic law.
b. Each such Party shall formulate and submit a low-carbon strategy for long-term net emissions reductions of
at least [ ] by 2050.
2.
Recognizing that the circumstances of countries naturally evolve over time, Paragraph 1 above shall
apply, when Appendix 1 is next updated, to other Parties in accordance with objective criteria of
economic development.
3. Developing country Parties whose national circumstances reflect greater responsibility or capability:
a. For each such Party, Appendix 1 includes nationally appropriate mitigation actions in the 2020/[] timeframe
that are quantified (e.g., reduction from business-as-usual) and are consistent with the levels of ambition
needed to contribute to meeting the objective of the Convention.
b. Each such Party shall formulate and submit a low-carbon strategy for long-term net emissions reductions by
2050, consistent with the levels of ambition needed to contribute to meeting the objective of the
Convention.
c. Appendix 1 shall include date(s) by which the Party will commit to the type of action referred to in
paragraph 1(a) above.
d. Other developing country Parties should implement nationally appropriate mitigation actions and develop
low-carbon strategies, consistent with their capacity.

What responsibility?
european capacity building initiative

• The state or fact of being accountable; liability,
accountability for something
• The fact of having a duty to do something.

What equity?
I. In general.
The quality of being equal or fair; fairness, impartiality; even-handed dealing.
II. In Jurisprudence.
The recourse to general principles of justice (the naturalis æquitas of Roman
jurists) to correct or supplement the provisions of the law. equity of a statute: the
construction of a statute according to its reason and spirit, so as to make it apply to
cases for which it does not expressly provide.

b : the money value of a property or of an interest in a property in
excess of claims or liens against it.
Equality on the Durban Platform
“Treat like cases as like”
Nicomachean Ethics, V.3. 1131a10-b15;
Politics, III.9.1280 a8-15, III. 12. 1282b18-23
Full Aristotelian Conception
Descriptively equal cases ought to be treated equally, descriptively
unequal cases ought to be treated unequally, according to their degree
of inequality.

If gdpk = gdpm then GCk : GCm = GDPk : GDPm
If GDPk = GDPm then GCk : GCm = GDPk : GDPm

Capability = Gross Capability minus Capability Adjustment

Adjustment for what?
The size of the domestic poverty problem
• Poverty Capability Adjustment PCAk
Measuring the size of the poverty problem − two dimensions:
• Poverty Headcount PHk [number of poor people]
• Poverty Intensity Index: PIk [scalar]
• Global Poverty Capability Allowance Π [cu/person]
