Climate justice must mean accountability, not just promises and speeches. Those who have earned enormous profits from fossil fuels must also share responsibility for the environmental damage. The cost of pollution should not be pushed onto ordinary people, vulnerable communities and future generations. Developing nations, which often contribute less to global emissions, deserve meaningful support to face climate impacts. Climate finance must be transparent, accessible and directed towards communities that need it most. The principle that polluters must pay should be reflected in concrete policies and measurable action. COP31 must turn commitments into a fair system of responsibility and climate support. Protecting our planet requires courage, cooperation and accountability from those with the greatest resources. The climate crisis is a shared challenge, but responsibility must be matched with capacity and contribution. A sustainable future cannot be built while the costs of pollution are left for others to bear.
