There are good reasons, ranging from corporate sponsorship to vapidity, to have been cynical about recent Earth Day observances. But there are even more compelling reasons — the imminence of the climate crisis and the recent gain in denialists’ political standing — to put cynicism aside and come to Washington this Sunday for what organizers hope will be the “largest climate rally ever.”
Earth Day’s original national coordinator Denis Hayes and the Earth Day Network are aiming for a 40th anniversary revival of the “spirit of 1970” that catapulted environmentalism into public consciousness, launching a decade of environmental reforms, winning landmark legislation, and birthing the modern environmental movement.
The list of speakers is impressive for its heft and diversity. They include:
- Climate scientist James Hansen
- Filmmaker James Cameron (Avatar; Titanic) and author Margaret Atwood (The Handmaid’s Tale; The Blind Assassin)
- Business executives from Siemens and Phillips, and union leaders from the AFL-CIO and the SEIU
- Rainbow Coalition leader Jesse Jackson and NAACP V-P for advocacy Hilary Shelton
- Evangelical creation-care advocate Rev. Richard Cizik
- Climate-policy blogger Joe Romm
Plus a stellar roster of musicians including Bob Weir, Mavis Staples, Willy Colon, Booker T, and Sting
And the program’s diversity includes sharp differences over climate policy. Hansen in recent years has moved beyond climate science to climate politics, becoming the most visible (and perhaps most aggressive) U.S. advocate of fee-and-dividend — a federal carbon tax whose revenues would entirely be returned, per capita, to the American people. For his advocacy and his criticism of carbon cap-and-trade, Hansen has been censured by Romm, the climate blogger for the Center for American Progress, which is closely linked to cap-and-trade advocates in the Democratic Party and the mainstream environmental movement.
On Sunday, these differences can and should be put aside. As Romm did in his blog on the rally, we defer to Denis Hayes’ post on Grist:
Humanity must swiftly abandon dirty energy sources and switch to safe, clean, decentralized, renewable energy sources like solar, wind, and geothermal. The world, led by America, must abandon the appallingly inefficient way it uses energy and swiftly embrace the most efficient new housing, transport, and industrial processes that exist. We Americans must slash our politically risky and economically catastrophic dependence on the oil wealth of nations that don’t like us very much.
A necessary—though not sufficient—common denominator is to establish a price on carbon that reflects the costs of climate disruption, blowing the tops off mountains, and acidifying the world’s oceans. We must place a firm cap with no loopholes on the amount of carbon fuels we consume each year and ratchet that cap down at a prescribed rate every year in the future until we hit something very close to zero. Only a federal law can accomplish this goal.
If this were easy, we would have begun a quarter century ago. The junk science, climate-denying interest groups are rich, powerful, and ruthless. But sooner or later they will lose. Sooner is better
They will lose for the same reason that IBM and Control Data lost to Microsoft, Apple and Dell. They will lose for the same reason that Ma Bell—the most powerful monopoly in the world—lost to cellular upstarts and Internet-telephony. They lost because their thinking was anchored in the past instead of envisioning the future
The junk science, climate-disruption-denying interest groups will lose because 19th century answers won’t solve 21st century problems.
At some point, this climate-disrupting madness has to start to stop. Come to the Mall between the Capitol Building and the White House on Sunday, April 25. Bring your spouse, your parents, your kids, your neighbors, your friends, your co-workers, your congregation, your bowling league. Vote with your bodies on April 25th at the largest climate rally ever.
While we at the Carbon Tax Center differ with Denis’s emphasis on a cap — we’re convinced that only a carbon tax or fee can give U.S. entrepreneurs, investors and families the clear price signal they need to move to clean technologies, fuels and lifestyles — we salute Denis’s 40 years of advocacy (some of which is on fine display in the documentary Earth Days that PBS is airing this week).
We also salute the late Sen. Gaylord Nelson of Wisconsin, who more than any other individual conceived Earth Day (originally as a national day of teach-ins on the environmental crisis) and whose staff hired Denis Hayes to co-ordinate it.
Let’s come to the Mall this Sunday and make our voices heard for climate sanity and the central policy measure that can take us there: a federal, revenue-neutral carbon tax.


The Senate climate debate detoured from cap-and-trade legislation today as the Energy and Natural Resources Committee weighed alternatives like a carbon tax or even sector-specific limits on power plants.
In an earlier part of
economists who’ve considered the question, I’m convinced that a clear, transparent, gradually-increasing price on carbon pollution is essential to spur energy conservation as well as development and implementation of alternatives to fossil fuels. A carbon tax, with revenue recycled directly to households to build political support and mitigate the economic impacts of what portends to be a decades-long trek to a low carbon economy, offers a real “game changer” to move broadly enough to substantially mitigate climate catastrophe.
The House
This perverse consequence of a carbon cap makes perfect sense, unfortunately. Consider a commuter who, independent of any price signal or federal legislation, resolves to give up solo car commuting for a carpool. Under a cap system, this “exogenous” reduction in demand for carbon emitting will lead to a slightly lower emission permit price — thus stimulating some additional use of fossil fuels elsewhere. The incremental usage might be a reciprocal departure from a carpool, or cranking up the heat, or a return to buying bottled water rather than refilling at the tap … or any of a thousand other ways to burn carbon. The result, in the end, will be the same: virtue in one arena will be offset elsewhere, due to the price-equilibrium-seeking mechanism of the cap.
Of course, emission targets in 2050 have limited practical meaning — present leaders will be dead or doddering by then — so these differences may be patched up. The important point is that other nations are unlikely to make real concessions on emissions if the United States is not addressing the climate matter seriously.
There is little hope of shifting to a low-carbon economy without a clear, transparent price on carbon emissions. While ACESA’s proponents claim that its cap-and-trade provisions “
