"Divisions over money between rich and poor countries re-emerged as nations submitted their plans for tackling climate change to the UN.
India, the last big emitter to publish its contribution, said it would need $2.5 trillion to meet its targets.
The Philippines said that without adequate climate compensation, their cuts in emissions wouldn't happen.
The UN says the plans increase the likelihood of a strong global treaty.
148 countries, out of a total of 196, have met a UN deadline for submitting a plan, termed an Intended Nationally Determined Contribution (INDC).
These INDCs cover close to 90% of global emissions of carbon dioxide. The commitments will form the centrepiece of a new global agreement on climate change that nations hope to agree in Paris in December.
Independent analysts at the Climate Action Tracker said that the plans, when added up, meant the world was on track for temperature rises of 2.7 degrees C above pre-industrial levels.
This is above the 2 degree target generally accepted as the threshold for dangerous climate change. But it is a significant improvement on a previous assessment of 3.1 degrees, made when fewer plans had been submitted.
India's contribution, which promised to reduce the carbon intensity of their emissions but didn't commit to peaking their CO2, drew praise from around the world.
"It's highly significant that India is joining the ranks of so many other developed and developing countries in putting serious commitments on the table ahead of the Paris climate talks," said former UK environment minister Richard Benyon MP".
