Nature is vital to our success in fighting climate change and its real-world impacts. To unlock nature’s climate potential, we need investments to go to impactful nature-based climate solutions (NbCS), which refer to strategies to conserve, restore or improve the management of natural and working ecosystems for their climate benefits.

However, in a research paper recently published by myself and others, we found markets for NbCS were getting ahead of the science. In particular, we found many NbCS where carbon crediting was proposed or implemented had questionable scientific foundations.

We need NbCS to work, and we’re spending tens of millions in the hopes they do. Yet as our study shows, questions remain on how we can achieve the best ground-level outcomes and maximize the enormous potential of these solutions to lower greenhouse gas concentrations.

To illustrate how NbCS can work successfully, we need to look at science and implementation and understand how these two key components are different, but also interconnected.

Let’s start by thinking about your car.

We need to close a mercury pollution loophole for lignite coal plants

(This post was co-authored by EDF attorney Richard Yates)

The Environmental Protection Agency is soon expected to update our national protections against mercury and other toxic pollution from coal-fired power plants – pollution that is extremely dangerous to human health and has been linked to brain damage in children.

EPA proposed strengthening the Mercury and Air Toxics Standards and closing a loophole for lignite coal and is expected to issue its final update soon. EDF has found that, even as we have made great progress in reducing mercury pollution overall, the lignite coal loophole leaves parts of the U.S. at especially high risk.

Mapping Big Mercury Polluters

[(i) The owner/operator of the Comanche plant in Colorado has announced its intention to retire unit 2 by 2025 and unit 3 by 2030; unit 1 retired in 2022. (ii) The owner/operator of the Sherburne County plant in Minnesota has announced its intention to retire unit 1 by 2025 and unit 3 by 2034; unit 2 retired in 2023. (iii) The owner/operator of the Cardinal plant in Ohio has announced its intention to retire unit 3 by 2028; units 1 and 2 have no scheduled retirement dates. (Data: EPA’s Clean Air Markets Program Data; EIA’s 2022 Form EIA-860 Data – Schedule 3)] 

Two years ago, EDF published a map of the top 30 mercury-polluting power plants in 2020 across the United States. We have now refreshed this map based on data from 2022, and you can see the results above.

Charting the path to equity: unveiling new Just Transition and Safeguards Framework

As the world moves towards greener, low-carbon futures, it’s imperative that no one is left behind – including those working in fossil fuel industries and the communities they support. 

A new report from Environmental Defense Fund, ‘Just Transition and Safeguards Framework offers a roadmap for countries and energy companies alike to successfully navigate the complexities of transitioning to clean energy while ensuring fairness and equity at every step of the way. 

Guidance from this framework outlines how to empower local stakeholders – from frontline communities to Indigenous Peoples – ensuring everyone has a seat at the table and a fair share in the benefits of this monumental shift. 

The concept of a ‘just transition’ isn’t new by any means. It was first developed by North American trade unions and environmental justice advocates and has since become a global call to action. As this big idea – which is simultaneously inspiring, ambiguous, and vast in scope – spreads across the world, it must adapt to local challenges, economic realities, and social norms.  

While a just transition will (and should) look different from West Virginia to South Africa, EDF’s framework aims to help decision-makers understand the principles that should be core to every just transition plan – removing the ambiguity and providing clear waypoints toward true climate justice.

Governor Inslee moves Washington state one step closer to linking carbon market with California and Quebec

Today, the state of Washington took a big step toward linking its cap-and-invest program with the carbon markets in California and Quebec, a move that could boost climate action and create a more stable, more predictable market for all. Governor Inslee signed E2SB 6058 into law, which will further align Washington’s program with the joint California-Quebec program (known as the Western Climate Initiative) and facilitate a smoother linkage process.

This latest development builds on the momentum of last week’s joint statement from the three jurisdictions, in which they expressed their shared interest in the potential creation of a larger, linked market among them. While Governor Inslee and Washington policymakers are tackling climate change head-on and trying to strengthen the state’s carbon market, a wealthy hedge fund executive is trying to bring climate progress to a screeching halt through a ballot initiative that would end the program altogether. The contrast between the two outcomes for Washington’s cap-and-invest program could not be starker.

Here’s what you need to know about the linkage bill and what’s at stake with Washington’s program.

Cherry blossoms: a microcosm of the global climate crisis

(This blog was co-authored by EDF Climate Scientist Fiona Lo)

Washington D.C.’s famous cherry blossoms are once again blooming earlier than expected.  

In fact, this year’s peak bloom occurred two and a half weeks earlier than the average over the past 100 years, due to near-record warm temperatures in March. 

This ranks as the second earliest peak bloom on record. Even the cherry blossom bud cycle occurred faster than any other year in the last two decades.  

So what is happening and why is this significant?  

Here we break down what you need to know about cherry blossoms and climate change.

How to act fast and smart (and where to move more cautiously) on nature-based climate solutions

This post is authored by Mark Moroge, Vice President of Natural Climate Solutions at Environmental Defense Fund.

We know that nature-based climate solutions are among our greatest assets when it comes to tackling climate change. Conserving, restoring and improving the management of nature – alongside reductions in new fossil fuel use – can provide at least 20% of the cost-effective climate mitigation needed between now and 2030 to stabilize warming to below 2 °C.

We also know that we need much greater investment in nature to achieve its climate change mitigation potential: the world must close a $4.1 trillion financing gap in nature by 2050 to achieve climate goals.

But with a wide variety of potential solutions on offer, and with carbon markets for financing these solutions under intense scrutiny, it is essential that credit purchases prioritize those solutions that have strong scientific backing. Otherwise, we risk undermining trust in the potential of these markets to deliver climate results.

That’s why a new scientific paper published this week in Nature Climate Change is so important. Here we explain the findings and provide two key lessons for advancing nature-based climate solutions.

Scientific confidence in different solutions varies

The study, carried out by 27 experts from 11 institutions, including the Environmental Defense Fund, The Nature Conservancy and Columbia University, brings a deep scientific assessment of 43 nature-based climate solutions that have been implemented or proposed for use in carbon markets.

Through an extensive literature review and expert elicitation process, it found a wide range in scientific confidence across, and within, the different solutions.
