TRUMP EXPOSES CLIMATE DEAL

Power plants executive order shows that Paris Agreement is a paper tiger

President Trump’s executive order eliminatin­g President Obama’s standards for power plants guts the only substantia­l U.S. measure to reduce harmful carbon emissions, and in doing so reveals the emptiness of the Paris climate treaty.

Climate change is real and mostly caused by humanity. According to the Internatio­nal Energy Agency, the U.S. promised to cut more energy-related CO2 emissions than any country in the world from 2013 to 2025. The problem is that this promise never had much ground in reality.

The primary substantia­l measure America has ever offered that would achieve the promised cuts was the Clean Power Plan, which required the U.S. power sector to reduce CO2 emissions.

Yet if fully enacted, it would have achieved just a third of the U.S. promises under the Paris Agreement. If it had remained in effect for the entire century, my peer-reviewed research using United Nations climate change models found that it would have reduced temperatur­e rises by a trivial 0.023 Fahrenheit. WASTED DECADES Without the Clean Power Plan, U.S. emissions will likely increase slightly. Yet despite eliminatin­g the actual policy that it relied on to achieve its promises, America will remain party to the Paris treaty, which has been sold to the world as the ultimate deal to fix climate change.

This absurd situation shows that the treaty is nothing but a paper tiger: Its only legal underpinni­ng is that all nations submitted promises — but those promises do not need to be kept.

Even if every nation fulfilled everything promised, it would get us nowhere near achieving the treaty’s unrealisti­c goal to keep temperatur­e rises under 1.5 degrees Celsius. The U.N. itself has estimated that even if every country lived up to every single promised carbon cut between 2016 and 2030, emissions would be cut by just one-hundredth of what is needed to keep temperatur­e rises below 2 C.

Moreover, many poor nations signed the treaty largely because of a promise of $100 billion a year in “climate aid” from rich nations, starting from 2020. Over the past five years, rich countries have managed to come up with only a 10th of one year’s promise.

It is only a matter of time before taxpayers from wealthy nations balk at the bill waiting for them. That will make many developing countries back out.

This approach rehashes a failed policy that wasted decades: From 1998, the Kyoto Protocol was sold as the solution to climate change, although every honest analysis showed that its impact would be trivial. Yet it kept government­s, non-profit organizati­ons and pressure groups focused on living up to the protocol rather than finding solutions.

Unless we change tack, the preoccupat­ion with a similarly toothless Paris treaty will waste decades more.

The underlying problem with the treaty is that today’s green solar and wind technology is still very inefficien­t, requiring hundreds of billions in annual subsidies for trivial carbon cuts. Therefore, trying to cut emissions significan­tly requires not just buying off poor nations, but also very high costs.

Calculatio­ns using the best peer-reviewed economic models show the global price tag of all the Paris promises — through slower gross domestic product growth from higher energy costs — would reach $1 trillion to $2 trillion every year from 2030.

And if America had managed to pass carbon-cutting policies to live up to its big promises, analysis shows that it would have re- duced U.S. GDP by more than $150 billion each and every year throughout the century.

We need to focus instead on innovating the price of green energy down below fossil fuels. This would be a much more effective response to climate change, and speed up temperatur­e cuts. EMPTY PROMISES A panel of Nobel laureates for the project Copenhagen Consensus on Climate found that the best long-term policy should focus on dramatic increases in global energy research and developmen­t. A group led by Bill Gates has already stepped up to promise a doubling to $30 billion. Yet our researcher­s showed that we should be even more ambitious and increase this sixfold, to reach at least $100 billion a year. Trump campaigned on increases in infrastruc­ture spending. Especially given he has proposed cuts to clean energy agencies, it is to be hoped that more money is allocated to energy R&D.

Global warming is a challenge that deserves a response. But chasing a treaty of empty promises is no response at all.
