Here’s the release from the New Climate Institute:
On current unconditional pledges, the world is heading for a 3.2°C temperature rise Technologies and policy knowledge exist to cut emissions, but transformations must begin now G20 nations account for 78 per cent of all emissions, but 15 G20 members have not committed to a timeline for net-zero emissions
Geneva, 26 November 2019 – On the eve of a year in which nations are due to strengthen their Paris climate pledges, a new UN Environment Programme (UNEP) report warns that unless global greenhouse gas emissions fall by 7.6 per cent each year between 2020 and 2030, the world will miss the opportunity to get on track towards the 1.5°C temperature goal of the Paris Agreement.
UNEP’s annual Emissions Gap Report says that even if all current unconditional commitments under the Paris Agreement are implemented, temperatures are expected to rise by 3.2°C, bringing even wider-ranging and more destructive climate impacts. Collective ambition must increase more than fivefold over current levels to deliver the cuts needed over the next decade for the 1.5°C goal.
2020 is a critical year for climate action, with the UN climate change conference in Glasgow aiming to determine the future course of efforts to avert crisis, and countries expected to significantly step up their climate commitments.
“For ten years, the Emissions Gap Report has been sounding the alarm – and for ten years, the world has only increased its emissions,” said UN Secretary-General António Guterres. “There has never been a more important time to listen to the science. Failure to heed these warnings and take drastic action to reverse emissions means we will continue to witness deadly and catastrophic heatwaves, storms and pollution.”
The Intergovernmental Panel on Climate Change (IPCC) has warned that going beyond 1.5°C will increase the frequency and intensity of climate impacts.
“Our collective failure to act early and hard on climate change means we now must deliver deep cuts to emissions – over 7 per cent each year, if we break it down evenly over the next decade,” said Inger Andersen, UNEP’s Executive Director. “This shows that countries simply cannot wait until the end of 2020, when new climate commitments are due, to step up action. They – and every city, region, business and individual – need to act now.”
“We need quick wins to reduce emissions as much as possible in 2020, then stronger Nationally Determined Contributions to kick-start the major transformations of economies and societies. We need to catch up on the years in which we procrastinated,” she added. “If we don’t do this, the 1.5°C goal will be out of reach before 2030.”
G20 nations collectively account for 78 per cent of all emissions, but only five G20 members have committed to a long-term zero emissions target.
In the short-term, developed countries will have to reduce their emissions quicker than developing countries, for reasons of fairness and equity. However, all countries will need to contribute more to collective effects. Developing countries can learn from successful efforts in developed countries; they can even leapfrog them and adopt cleaner technologies at a faster rate.
Crucially, the report says all nations must substantially increase ambition in their Nationally Determined Contributions (NDCs), as the Paris commitments are known, in 2020 and follow up with policies and strategies to implement them. Solutions are available to make meeting the Paris goals possible, but they are not being deployed fast enough or at a sufficiently large scale.
Each year, the Emissions Gap Report assesses the gap between anticipated emissions in 2030 and levels consistent with the 1.5°C and 2°C targets of the Paris Agreement. The report finds that greenhouse gas emissions have risen 1.5 per cent per year over the last decade. Emissions in 2018, including from land-use changes such as deforestation, hit a new high of 55.3 gigatonnes of CO2 equivalent.
To limit temperatures, annual emissions in 2030 need to be 15 gigatonnes of CO2 equivalent lower than current unconditional NDCs imply for the 2°C goal; they need to be 32 gigatonnes lower for the 1.5°C goal. On an annual basis, this means cuts in emissions of 7.6 per cent per year from 2020 to 2030 to meet the 1.5°C goal and 2.7 per cent per year for the 2°C goal.
To deliver on these cuts, the levels of ambition in the NDCs must increase at least fivefold for the 1.5°C goal and threefold for the 2°C.
Climate change can still be limited to 1.5°C, the report says. There is increased understanding of the additional benefits of climate action – such as clean air and a boost to the Sustainable Development Goals. There are many ambitious efforts from governments, cities, businesses and investors. Solutions, and the pressure and will to implement them, are abundant.
As it does each year, the report focuses on the potential of selected sectors to deliver emissions cuts. This year it looks at the energy transition and the potential of efficiency in the use of materials, which can go a long way to closing the emissions gap.
From The Washington Post (Brady Dennis):
“We need to catch up on the years in which we procrastinated,” a top official says.
The world has squandered so much time mustering the action necessary to combat climate change that rapid, unprecedented cuts in greenhouse gas emissions offer the only hope of averting an ever-intensifying cascade of consequences, according to new findings from the United Nations.
Already, the past year has brought devastating hurricanes, relentless wildfires and crippling heat waves, prompting millions of protesters to take to the streets to demand more attention to a problem that seems increasingly urgent.
Amid that growing pressure to act, Tuesday’s U.N. report offers a grim assessment of how off-track the world remains. Global temperatures are on pace to rise as much as 3.9 degrees Celsius (7 degrees Fahrenheit) by the end of the century, according to the United Nations’ annual “emissions gap” report, which assesses the difference between the world’s current path and the changes needed to meet the goals of the 2015 Paris climate accord.
As part of that deal, world leaders agreed to hold warming to “well below” 2 degrees Celsius compared with preindustrial levels; the current trajectory is nearly twice that.
Should that pace continue, scientists say, the result could be widespread, catastrophic effects: Coral reefs, already dying in some places, would probably dissolve in increasingly acidic oceans. Some coastal cities, already wrestling with flooding, would be constantly inundated by rising seas. In much of the world, severe heat, already intense, could become unbearable.
Global greenhouse gas emissions must begin falling by 7.6 percent each year beginning 2020 — a rate currently nowhere in sight — to meet the most ambitious aims of the Paris climate accord, the report issued early Tuesday found. Its authors acknowledged that the findings are “bleak.” After all, the world has never demonstrated the ability to cut greenhouse gas emissions on such a scale.
