Kiwis join zero-emission call
Commonwealth academies in urgent plea for govts to act
Nscience ew Zealand’s leading science body has joined an unprecedented Commonwealth-wide push for governments to slash greenhouse-gas emissions to net zero.
Ahead of next month’s Commonwealth summit in the UK, Royal Society Te Aparangi and 21 other major national academies and societies of science have urged leaders to look to the evidence on climate change and act now.
Their joint statement, drawn from the consensus views of tens of thousands of scientists, marks the first time Commonwealth academies have come together to urge governments toward achieving net-zero emissions this century.
New Zealand has pledged to cut its emissions by 30 per cent below 2005 levels, and 11 per cent below 1990 levels, under the 160-party Paris Agreement. But the society’s president, Professor Richard Bedford, said these were just the first steps in a long journey.
“Even if all the country commitments from the Paris Agreement are met, the latest data shows that by the end of the century the global climate is likely to be 3C above pre-industrial levels,” Bedford said.
“This is substantially higher than the Paris target to limit warming to less than 2C, and would have profound impacts affecting billions of people throughout the world.
“Here in the South Pacific, we are acutely aware of the risks of climate change and sea-level rise to our Pacific Island neighbours and we urge all nations to take immediate action on climate change,” he said.
Sustainability would be discussed at the summit, with a particular focus on the resilience of developing and vulnerable countries to climate change.
“Recognising different capacities, challenges and priorities, the approaches of each nation will not be the same,” Bedford said.
“But, they must be informed by the best available scientific evidence, monitoring and evaluation.”
The society had produced a trio of recent scientific reports on climate change in New Zealand, focused on broad implications, impacts on health and opportunities for mitigation.
