In their bids to showcase climate leadership ahead of the upcoming UN Climate Change Conference in Glasgow (COP26), world leaders are once again talking of ambitious carbon reduction targets. For example, US PresidentJoe Biden has set the goal of creating “a carbon pollution-free power sector by 2035 and net-zero emissions economy by no later than 2050”.
Most rich nations’ governments have formulated similar ambitions. Unfortunately,thattarget will be prohibitively expensive. A new study in the renowned journal Natureshows the cost of 95%reduction by 2050 — almost Biden’s net-zero — would cost 11.9%of GDP or more than $11,000present-daydollars for each American every year.
Twenty-four years havepassedsince the adoption of the Kyoto Protocol, the first major global agreement promising to cut carbon emissions. Since then the world has hosted hundreds of climate summitsandrich nations have reliably talked green;but emissions have kept increasing becauseno leaders wanttosticktheircitizenswiththehugeprice tag.
In a very frank analysis of the past decade of climate policy the UN calls the 2010s a “lost decade”. Itcannot tell the difference between what has happened and a world that adopted no new climate policies since 2005. Just think about that: afterall these climate summits and all these climate promises, when looking at the actual emissions we can’t tell the difference from the world we’re in and a world where we didn’t care to do anything about climate since 2005.
Thatputs the challenge with COP26 in perspective. World leaders can choose to do what they have done over decades and contribute toyet anotherclimate meeting in a world overflowingwithwell-meaning climate summits. Nation after nation will show up and make nice-sounding promises liketransforming their electricity sectors(responsible for only 19%of all the energy the world consumes) to renewables. There is a good chancethosepromises will eventually berevealed to be justas hollow as the last decades’ worth of promises, becausevoterswill reject the bill.
Or leaders could finally go down a different path. The real challenge with the current approach to climate policy is that as long as cutting emissions is expensive, leaders will talk a lot but do little. In the rich world, this is to avoid following in the embarrassing footsteps of French PresidentEmmanuelMacron, who had to backtrack to the yellow vest movement after proposing a modest hike in petrolprices. In the poorer world nations have far more important priorities, such as driving economic growth and getting their populations out of poverty.
What is needed is a much stronger focus on green energy research. If the world could innovate green energy that was cheaper than fossil fuels, we would have solved global warming. Everyone would switch, includingAsia, Africa and Latin America. The Copenhagen Consensus has found that the most effective, long-term climate policyisin investing a lot more resources in green R&D.
During the 2015 Paris climate summit more than 20 countriespromisedto double R&D spending on green energy innovations by 2020. Unfortunately, they arefailing this promise, too. Instead of making big and expensive promises that future governments will have to backtrack on oncecitizensprotest against rising power bills, leaders should immediately commit to spending much more on green R&D.
Not only have most nations already madethatpromise, but compliancecan be verifiedwithin 12 months. And the totalcostfor each nation will be much lower than current climate policies. For 2030, our Nobel economists suggested that the world increase its spending another $70bn per year. Comparethatto the $195bn we arecurrentlyspending on subsidising ineffective green energy.
At COP26 world leaders would be well advised to not repeat what has failed in the past past decades, but to emphasise a cheaper, smarter, better way forward that will actuallyhelpfix climate change — invest dramatically more in green R&D to make sure we innovate technologies that can help the whole world to cheaply switch from fossil fuels.
