China, the world’s top polluter, unveiled plans for an emissions trading scheme on Tuesday.
This carbon market, which would allow facilities to trade credits for the right to emit planet-warming greenhouse gases, would initially start with China’s power sector. It would include approximately 1,700 utilities that each emit more than 26,000 tons of carbon a year—adding up to more than 3 billion tons of carbon emissions annually. Experts indicate it will take at least a year for the program to get underway, although the National Development and Reform Commission (NDRC) gave no hard deadlines for launch. Over time, China is expected to gradually tighten annual allocations to force up the emissions credit price.
“Everything is gradual, step by step,” said Li Junfeng, a senior government adviser on the carbon market plan.
Nine regions and cities, including Jiangsu, Fujian and seven regions with pilot schemes, will coordinate to establish the program, the NDRC said.
Although details of the market’s expansion have not yet been released, once the market is fully operational, it is expected to cover eight sectors: power; iron and steel; non-ferrous metals, such as aluminum; chemicals; petro-chemicals; paper; building materials; and civil aviation. Designed to encompass as much as 40 percent of the nation’s total emissions, the program aims to be more than twice the size of the European Union’s emissions trading scheme.
Efforts to Replace the Clean Power Plan Underway
The U.S. Environmental Protection Agency (EPA) released an Advance Notice of Proposed Rulemaking for the Clean Power Plan Monday, asking the public to comment on what a replacement rule might look like. In October, the Trump administration proposed repealing the Obama-era rule, which sets state-by-state carbon reduction targets for power plants.
“EPA is considering proposing emission guidelines to limit greenhouse gas (GHG) emissions from existing electric utility generating units (EGUs) and is soliciting information on the proper respective roles of the state and federal governments in that process, as well as information on systems of emission reduction that are applicable at or to an existing EGU, information on compliance measures, and information on state planning requirements under the Clean Air Act (CAA),” the notice reads.
The notice followed an announcement Friday that the EPA plans to terminate the rule in 10 months. The agency has suggested that it could have a replacement by October 2018. The news came as part of a broader Trump administration agenda to retract many environmental and other regulations.
Studies Strengthen Link between Human-Caused Climate Change and Some Extreme Weather
On the heels of an announcement by the Trump administration that climate change would be removed from the list of national security threats, new studies are pointing to further connections between global warming caused by human activities and past extreme weather events such as heat, drought, flooding and wildfire outbreaks.
A United Kingdom Energy and Climate Intelligence Unit (ECIU) analysis of 59 studies published in the last two years examined the influence of climate change on extreme weather. It suggests that warming worsened that weather in 70 percent of cases.
A separate group of studies published last week in Explaining Extreme Events in 2016 from a Climate Perspective, a special supplement to the Bulletin of the American Meteorological Society(BAMS), analyzed 27 extreme weather events from 2016, the hottest year in recorded history, and found that human-caused climate change was a “significant driver” for 21 of them.
Many of the BAMS studies found a strong likelihood of a human influence on extreme weather events but stopped short of saying they were outside the realm of natural variability, and not all of the studies linked 2016’s extreme events to human activity.
But it’s the first time in BAMS history that scientists have found some events that could not have occurred in the absence of global warming. According to the new reports, the three definitively human-caused extreme events in 2016 were the overall global temperature increase; record heat in Asia; and marine hot spots in the Gulf of Alaska, Bering Sea (where a mass of warm ocean water has been dubbed “the Blob”) and off the coast of northern Australia.
“For years, scientists have known humans are changing the risk of some extremes,” said Jeff Rosenfeld, BAMS editor in chief (subscription). “But finding multiple extreme events that weren’t even possible without human influence makes clear that we’re experiencing new weather, because we’ve made a new climate.”
