Nusa Dua Declaration
Getting to zero: Mobilizing parliaments
to act on climate change
Endorsed by the 144th IPU Assembly
(Nusa Dua, 24 March 2022)
We, Members of Parliament, gathered together at the 144th IPU Assembly in Nusa Dua,
Indonesia, recognize the urgent need to address the climate crisis. Climate change poses
an existential threat to humankind and immediate action must be taken to minimize its
worst impacts.
Our current economic structures, energy use practices and food systems are causing
devastating consequences in all regions of the world, including hotter temperatures, an
increase in extreme weather events, sea level rise and the loss of biodiversity. Flooding
and cyclones have caused large-scale population displacement in South Asia. Recurrent
droughts in East and Southern Africa have repeatedly destroyed crops and caused
widespread food insecurity. Rising sea levels are reducing the land mass of small,
low-lying nations across the Pacific.
The recent findings of the Intergovernmental Panel on Climate Change (IPCC) show that
the goal of limiting global warming to 1.5 degrees Celsius, or even 2 degrees Celsius, will
be unreachable unless there are immediate reductions in greenhouse gas emissions,
1
and that irreversible damage from climate change is already occurring.

The burning of
fossil fuels, increased livestock farming and deforestation are all major causes of rising
emissions. Implementation of the Paris Agreement,
3
the landmark legally binding
international climate change treaty, is critical for ensuring that countries make rapid and
deep cuts in their emissions so that we reach a climate neutral world by 2050.
As parliamentarians, we must ensure that the climate commitments outlined in the Paris
Agreement and other international agreements, as well as the Sustainable Development
Goals, are met. As representatives of the people, we must ensure that the needs of our
populations, particularly those on the front lines of climate change, are addressed. We
acknowledge that there are costs to addressing climate change, but the costs of inaction
are far greater.
The science is clear and instructive: to keep the 1.5 degrees target within reach, we must
achieve net zero emissions by producing less carbon than the amount we take out of the
atmosphere by the second half of this century. We must demonstrate strong political
leadership in setting the framework required for net zero emissions.
