ST. PAUL, Minn. -- The federal government is preparing to implement new auto emission standards, and so is the state of Minnesota.

Backers of both initiatives say there will not be any problems with overlap. Through an executive order, President Joe Biden is calling for half of all passenger vehicles sold by 2030 to have zero emissions. Another part of the plan focuses on gas- powered engines, with tougher benchmarks for fuel emissions for 2023 and 2024 vehicles.

Anjali Bains, Senior Clean Transportation Manager at Minnesota-based Fresh Energy, said the federal goals match up with what will take place in Minnesota for 2025 models.

"So it matters for us because Minnesota will be following the federal emission standards for the next two years," Bains explained. "So, if the Biden administration is updating those standards, that means we get to enjoy more fuel-efficient vehicles sooner than even what Clean Cars Minnesota would have allowed us to enjoy."

She noted if the federal fuel-emission standards hold, it would be a smooth carryover into Minnesota's plan, which would mean auto dealers located near neighboring states wouldn't have to worry about price differentials.

Minnesota's standards have received pushback from the auto-dealer industry. Meanwhile, some climate observers say Biden's plan won't do enough to reduce the impact of global warming.

Despite the similarities, Bains noted Minnesota's plan has a key difference.

"Where automakers are required to send more electric vehicles here, and that is not something the federal tailpipe emissions standards will seek to address," Bains pointed out.

When it comes to zero-emissions cars, the Biden administration goal is not legally binding. But a handful of automakers said they support the long-term target, and hope to achieve nearly 50% sales of electric vehicles by 2030.

Connecticut is celebrating its first estuary reserve, which will help identify environmental threats to waterways and natural resources.

Connecticut's first National Estuarine Research Reserve (NERR) designates more than 50,000 acres of Long Island Sound, adjacent marshes and upland areas for research on climate resiliency, water quality and fish and wildlife habitats.

Patrick Comins, executive director of the Connecticut Audubon Society, has been a strong advocate for the reserve and said it can be a catalyst for critical conservation activity.

"The research that sheds light on the strategies within the NERR for things like climate resilience and mitigation will not only benefit the species -- things like bluefish, saltmarsh sparrow, semipalmated sandpiper, within the NERR -- but will also benefit them wherever they occur, the habitat and the species," Comins outlined.

Nearly 50 species listed under the Connecticut Endangered Species Act can be found within the reserve.

Saturday's designation ceremony is invitation-only and will take place at 11 a.m. on the University of Connecticut's Avery Point campus, which will be the research reserve's headquarters. The reserve receives funding from the state and the National Oceanic and Atmospheric Administration.

Roughly $1 million per year will be earmarked for the reserve.

Kevin O'Brien, supervising environmental analyst for the Connecticut Department of Energy and Environmental Protection, said the reserve's educational component for local schools is also key, adding it will help foster environmental stewardship.

"As you're collecting information on changes in water temperature or water quality, opportunities for educational programs to get students to the reserve to work with that data to understand what some of the data might suggest about what the estuary's health is," O'Brien explained.

The research reserve is the country's 30th. Speakers at Saturday's event will include national and state government leaders, representatives from The University of Connecticut and others. After the ceremony, guests will be invited to join a boat tour of a section of the reserve.

A totem pole from Washington state promoting a free-flowing Snake River has nearly completed its 2,500-mile journey around the Northwest.

The Spirit of the Waters Totem Pole Journey started in early May in Bellingham, near the Lummi Indian Reservation where it was carved. Since then, it's traveled through Oregon, Idaho and back to Seattle on Thursday.

Jewell James, head carver of the House of Tears Carvers, said the pole is 16 feet long, weighs 3,000 pounds and sits on two carved, eight-foot-long salmon.

"A killer whale that has a baby whale on its nose to reflect Tahlequah, the whale that lost her calf and carried it around Puget Sound for 17 days and over 1,000 miles trying to get the message to us, the human beings, that we are killing them off," James explained.

James noted the journey is supporting the Shoshone-Bannock Tribes' call to remove four dams on the lower Snake River in southeast Washington, which are impeding salmon migration. The salmon's population drop in the Columbia River Basin in recent decades also has starved Southern Resident orcas in Puget Sound.

Dam supporters said they are integral for barging and irrigation in the region. But James countered there is growing disappointment among tribes and conservation groups with lawmakers' inaction as salmon near extinction.

"They're more prone to protect the interests of corporations than they are the general public," James contended. "And we find that a little frustrating."

The journey has brought together tribal members, conservation groups and the faith community to call for the restoration of the Salmon River. The totem pole is making its final stop in Tacoma today.

This afternoon, members of the public will get to have a say on the management plan for the first new aquatic preserve created in Florida in 32 years.

In 2020, Gov. Ron DeSantis signed legislation to create the Nature Coast Aquatic Preserve, which will protect some 400,000 acres of seagrass spanning more than 700 square miles along Citrus, Hernando, and Pasco counties.

Keith Kolasa, aquatic services and waterways manager with the Hernando County Department of Public Works, said the goal is to be proactive in protecting many sensitive ecosystems.

"Protect and preserve a resource that's in good shape," said Kolasa, "versus trying to restore it similar to what we've seen in Tampa Bay and to the south, where there have been a lot of red tide and algae blooms."

The Florida Department of Environmental Protection will host two remaining public hearings, a virtual one at 6 p.m. today to present the draft Nature Coast Aquatic Preserve Management Plan to the public for their review and feedback, and an in-person meeting next Tuesday in Crystal River.

Details are on floridadep.gov.

The Nature Coast Aquatic Preserve is the second-largest aquatic preserve in Florida. Justin Grubich, science and policy officer with The Pew Charitable Trusts, said the management plan ensures that the way of life can thrive in the area that is heavily dependent on seagrass.

"Not only the biological inhabitants, all the sea turtles and manatees and fish and scallops that we like to catch and view," said Grubich, "but it also helps those coastal communities that depend on those resources for their livelihood."

Grubich said the management plan is a crucial component because it sets the road map for nearly everything that will happen at the preserve, from education to habitat monitoring.

It also identifies the priorities of maintaining those ecosystems and balancing them with public use.

Grubich said another critical component is gathering data management for research and learning about species beyond the areas currently known.
