New climate legislation put forward by Senate Democrats is "woefully" insufficient to avoid the worst effects of the climate crisis when compared to the warnings of the world's top scientists, green groups said Wednesday.

Led by Sen. Tom Carper (D-Del.), 34 Democrats released the Clean Economy Act on Wednesday. The bill calls for the gradual reduction of carbon emissions, reaching net zero by 2050—but leaves the action in the control of the EPA.

"If we're going to get out of the mess we've created, Congress needs to start listening to the desperate pleas of scientists and act decisively to cut emissions by at least half by 2030. Sadly this bill just doesn't cut it."

The agency, currently headed by former coal lobbyist Andrew Wheeler, would under the new law be directed to phase out carbon emissions with reduction targets in 2025, 2030, and 2040, eventually hitting net zero in 30 years.

"This is the quickest way we can, I think, jump-start government-wide climate action by encouraging agencies to use the tools that they already have," Carper said in a statement.

Friends of the Earth slammed that assesment, saying the legislation puts "too much faith in future administrations."

"We need binding emission reduction targets, in line with what climate justice and historical responsibility demand, far sooner than 2050," Friends of the Earth (FOE) told The Hill. "Unspecified interim targets are ill-suited to our moment of climate emergency."

The Clean Economy Plan is "based in false solutions," FOE added on Twitter.

.@SenatorCarper's climate bill falls far short of the scale of the climate crisis. A bill based in false solutions like cap & trade is hardly putting our best foot forward. We need act aggressively on climate. https://t.co/CgDJaPziC7 SCROLL TO CONTINUE WITH CONTENT Never Miss a Beat. Get our best delivered to your inbox.

In 2018, the U.N. Intergovernmental Panel on Climate Change (IPCC) released a study warning that world governments have only until 2030 to keep the warming of the plant to 1.5º Celsius in order to avoid the worst effects of the climate crisis. At the time, Friends of the Earth Europe warned that the European Union's proposal to reach net zero carbon emissions by 2050 was "simply too late."

"The climate crisis will never get solved with wishful thinking and half-measures that punt all-important decisions to the EPA," said Brett Hartl, government affairs director at the Center for Biological Diversity. "If we're going to get out of the mess we've created, Congress needs to start listening to the desperate pleas of scientists and act decisively to cut emissions by at least half by 2030. Sadly this bill just doesn't cut it."

In The Conversation last September, sustainable development professor Tim Jackson wrote a net zero target of 2050 ignores the global carbon budget set by the IPCC, which estimates the budget for the rest of this century is 420 billion tons of carbon.

"It is dangerously misleading for advanced nations to set target dates as far out as 2050," wrote Jackson. "Doing so ignores the importance of staying within a fair carbon budget and gives a false impression that action can be delayed. In reality, the only way to ensure that any developed country remains within its fair budget is to aim for an early net zero target."

Food & Water Action said Wednesday the U.S. is defying its "moral obligation" to quickly phase out all fossil fuels.

"We have to move off fossil fuels now," said Mitch Jones, the group's policy director. "Any climate proposal that does not explicitly stop the extraction of fossil fuels is not a serious climate proposal. Our first step must be to ban fracking, ban exports and imports of fossil fuels, and stop building new fossil fuel infrastructure. Anything less threatens future generations with an uninhabitable planet."
