Key takeaways

At the 64th session of Subsidiary Bodies (SB64) in Bonn, India urged scientific caution against incorporating undefined climate tipping points into official UNFCCC negotiations.
India stressed that the 1.5°C and 2°C targets set under the Paris Agreement are political temperature goals rather than scientifically proven tipping thresholds.
India warned that adopting ambiguous climate concepts threatens Global South interests by undermining core principles of Equity and CBDR.
India raised strong concerns over falling climate finance from developed nations and unilateral trade mechanisms like the EU's Carbon Border Adjustment Mechanism (CBAM).
The mid-year Bonn conference establishes the technical roadmap for COP31 in Antalya, Türkiye, supported by the SBI and SBSTA advisory bodies.

During the 64th Sessions of the Subsidiary Bodies (SB64) to the UNFCCC in Bonn, Germany, India called for scientific caution.
India urged delegates not to include the term climate tipping points in global talks without clear definitions and strong scientific consensus.
This mid-year meeting focused on laying technical foundations for the upcoming COP31 UN Climate Change Conference in Antalya, Türkiye.

A climate tipping point is a critical boundary in Earth's climate system.
Crossing this threshold triggers fast, self-reinforcing, and irreversible changes regardless of emission speeds.
Major global examples include the drying of the Amazon rainforest into a savanna and the collapse of the Atlantic Meridional Overturning Circulation (AMOC).
Other critical risks include severe coral reef bleaching and major disruptions to the Indian and West African monsoon systems.

India pointed out that the term lacks a universally accepted scientific definition.
The Indian delegation emphasized that big uncertainties remain regarding exact thresholds, timing, and impact sizes.
India insisted that climate decisions must rely on peer-reviewed scientific proof rather than vague words.
India clarified that the 1.5°C and 2°C targets under the Paris Agreement are political goals, not proven tipping points.
The European Union opposed India's stance and called it obstruction that could delay climate action.
India warned that vague thresholds in UNFCCC rules put unfair burdens on developing countries, hurting principles of Equity and CBDR.
India also expressed concern over falling climate finance and opposed unilateral trade policies like the EU's Carbon Border Adjustment Mechanism (CBAM).

The Bonn Climate Change Conference is the official mid-year climate meeting held under the UNFCCC.
It takes place every year before the main COP to review climate progress and prepare technical agendas.
Two bodies guide this summit: the Subsidiary Body for Implementation (SBI) and the Subsidiary Body for Scientific and Technological Advice (SBSTA).
The SBSTA provides technical advice using assessments from the Intergovernmental Panel on Climate Change (IPCC).
