Ditch new fossil fuel spending to reach net zero emissions – IEA

Investors should not fund new oil, gas and coal supply projects if the world wants to reach net zero emissions by mid-century, the International Energy Agency (IEA) said on Tuesday, in the top global watchdog’s starkest warning yet to curb fossil fuels.

Any abrupt halt to new oil and gas projects by next year still appears unlikely, however, as energy majors’ spending plans still tilt heavily towards hydrocarbons and oil-producing nations such as Norway plan new licensing rounds.

“The pathway to net zero is narrow but still achievable. If we want to reach net zero by 2050 we do not need any more investments in new oil, gas and coal projects,” Fatih Birol, the IEA’s executive director, told Reuters.

“It is up to investors to chose whatever portfolio they prefer but there are risks and rewards,” he added.

The 2015 Paris Agreement on climate change aims to cap the rise in temperatures to as close as possible to 1.5 degrees Celsius above pre-industrial times to avoid the most devastating impacts of climate change, which requires net zero greenhouse gas emissions by 2050.

The number of countries which have pledged to reach net zero has grown, but even if their commitments are fully achieved, there will still be 22 billion tonnes of carbon dioxide worldwide in 2050 which would lead to temperature rise of around 2.1C by 2100, the IEA said in its “Net Zero by 2050” report.

It sets out more than 400 milestones to achieving net zero in the report, intended to guide the next round of global climate talks which will take place in November in Scotland.

“(This is) a massive blow to the fossil fuel industry. This is a complete turnaround of the fossil-led IEA from five years ago,” said Dave Jones, global programme lead at Ember think-tank.

Environmental activists had previously said the IEA, whose analysis and data underpins energy policies of governments and companies around the world, underestimated the role of renewable power in its reports.

RENEWABLES

To achieve net zero, global investment in fossil fuel supply should fall from $575 billion on average over the past five years to $110 billion in 2050, with upstream fossil fuel investment restricted to maintaining production at existing oil and natural gas fields, the IEA said.

There should be no sales of new internal combustion engine passenger cars and the global electricity sector must reach net zero emissions by 2040, it added.

Massive deployment of renewable energy will be needed. Almost 90% of electricity generation should come from renewables by 2050 and most of the rest from nuclear power.

Solar photovoltaic additions should reach 630 gigawatts (GW) a year by 2030 and wind power needs to rise to 390 GW. Together, this is four times the annual record set last year for new capacity additions.

Annual emissions savings will depend heavily on investment and new technology such as direct air carbon capture and green hydrogen, according to the IEA, with around half of emissions reductions by mid-century compared to 2020 set to come from technologies currently under development.

“Around $90 billion of public money needs to be mobilised globally as soon as possible to complete a portfolio of demonstration projects before 2030,” the IEA said, noting that only $25 billion was currently earmarked for that period.

Every month from 2030, 10 industrial plants will need to be fitted with carbon capture technology, three new hydrogen-based industrial plants will need to be built and 2 GW of electrolyser capacity for green hydrogen production needs to be added at industrial sites, the report said.

Energy investment will need to rise to $5 trillion a year by 2030 to achieve net zero from $2 trillion today, it said, which will provide a boost to global annual GDP growth.
