The IPCCâs 6th world warning. What does it mean for parliamentarians?
The IPCCâs Sixth Assessment Report is sobering reading- and should galvanize action around the world. Parliamentarians are on the frontline.Â
The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. It gives regular updates on a sliding scale of scenarios for our global habitat, informed by the actions - or inaction - of the worldâs governments.
The latest synthesis report, published in February 2023, warns that the window of opportunity to limit global warming to no more than 1.5â°C is closing fast. Reaching a stage where human-caused emissions are at net zero by 2050 is still only the best-case scenario âyet most experts agree that this will be a minimum to have a chance of allowing the planet to stay below 2â°C of global warming.
The IPCC is unequivocal: fossil fuels must be made extinct and never revived: existing or planned fossil fuel infrastructure would, by itself, use up our carbon budget for 1.5â°C or even 2â°C. So, to stay below 1.5â°C of warming as called for by the Paris Agreement, we need to slash COâ emissions by 45% by 2030.Â
Taking preventative action now is better than seeking solutions in the future. As the IPCCâs Energy and Climate Intelligence Unit puts it: Avoiding a tonne of COâ today will almost always be easier and cheaper than sucking out COâ from the atmosphere later this century.
We must prioritize cutting human-caused emissions, along with offsetting future emissions with carbon sequestration measures.
Parliamentarians are key players when it comes to climate action. Legislation is a vital engine for driving national action on climate change. Support and leadership for MPs has never been more important.Â
The IPUâs Parliaments for the Planet campaign is a good starting point. The concept of the campaign is simple. Climate action begins at home. Parliaments and parliamentarians can already take steps to reduce their own carbon footprints â as well as more transformative action through legislation, budgets and scrutiny of measures to implement the Paris Agreement.
To help them, the IPU has identified 10 Actions for Greener Parliaments, which parliamentarians can consider as they work to foster a culture of sustainable change.
The IPCCâs 6th synthesis report is a warning. But it also offers hope, if action is taken.
It tells us that rapid decarbonization is not just right for the planet; it is cost-effective. The tools for shifting away from fossil fuels already exist and falling costs are making a sound business case for clean energy.Â
Other good news: climate policies are strengthening. The dual power of government and business is beginning to steer us away from the bleakest future outcomes.
