Clean energy progress is still far too slow to put global emissions into sustained decline towards net zero, according to a new International Energy Agency (IEA) report.
The ‘World Energy Outlook 2021’ found that a new energy economy is emerging around the world as solar, wind, electric vehicles and other low-carbon technologies flourish.
The analysis, however, delivers stark warnings about the direction in which today’s policy settings are taking the world.
But it also provides clear-headed analysis of how to move in a well-managed way towards a pathway that would have a good chance of limiting global warming to 1.5 °C and avoiding the worst effects of climate change.
The WEO-2021 shows that even as deployments of solar and wind go from strength to strength, the world’s consumption of coal is growing strongly this year.
This is pushing carbon dioxide (CO2) emissions towards their second largest annual increase in history.
IEA executive director Fatih Birol (pictured) said: “The world’s hugely encouraging clean energy momentum is running up against the stubborn incumbency of fossil fuels in our energy systems.
“Governments need to resolve this at COP26 by giving a clear and unmistakeable signal that they are committed to rapidly scaling up the clean and resilient technologies of the future.
“The social and economic benefits of accelerating clean energy transitions are huge, and the costs of inaction are immense.”
The WEO-2021 spells out clearly what is at stake: what the pledges to reduce emissions made by governments so far mean for the energy sector and the climate.
And it sets out what needs to be done to move beyond these announced pledges towards a trajectory that would reach net zero emissions globally by mid-century.
This is the Net Zero Emissions by 2050 Scenario from the IEA report published in May, which is consistent with limiting global warming to 1.5 °C.
As well as the Net Zero Emissions by 2050 Scenario, the WEO-2021 explores two other scenarios to gain insights into how the global energy sector may develop over the next three decades – and what the implications would be.
The Stated Policies Scenario represents a path based on the energy and climate measures governments have actually put in place to date, as well as specific policy initiatives that are under development.
In this scenario, almost all of the net growth in energy demand through 2050 is met by low emissions sources, but that leaves annual emissions still around today’s levels.
As a result, global average temperatures are still rising when they hit 2.6 °C above pre-industrial levels in 2100.
The Announced Pledges Scenario maps out a path in which the net zero emissions pledges announced by governments so far are implemented in time and in full.
In this scenario, demand for fossil fuels peaks by 2025, and global CO2 emissions fall by 40% by 2050.
All sectors see a decline, with the electricity sector delivering by far the largest. The global average temperature rise in 2100 is held to around 2.1 °C.
For the first time in a WEO, oil demand goes into eventual decline in all the scenarios examined, although the timing and speed of the drop vary widely.
If all today’s announced climate pledges are met, the world would still be consuming 75 million oil barrels per day by 2050 – down from around 100 million today – but that plummets to 25 million in the Net Zero Emissions by 2050 Scenario.
Natural gas demand increases in all scenarios over the next five years, but there are sharp divergences after this.
Birol added: “Today’s climate pledges would result in only 20% of the emissions reductions by 2030 that are necessary to put the world on a path towards net zero by 2050.
“Reaching that path requires investment in clean energy projects and infrastructure to more than triple over the next decade.
“Some 70% of that additional spending needs to happen in emerging and developing economies, where financing is scarce and capital remains up to seven times more expensive than in advanced economies.”
Insufficient investment is contributing to uncertainty over the future, the report found.
Spending on oil and natural gas has been depressed by price collapses in 2014-15 and again in 2020. As a result, it is geared towards a world of stagnant or even falling demand.
At the same time, spending on clean energy transitions is far below what would be required to meet future needs in a sustainable way.
