Digging in to defend clean energy tax credits
By Flannery Winchester
At the end of February, we told you: It’s prime time to defend the clean energy tax credits from the Inflation Reduction Act. As Republicans press forward on a budget reconciliation package that could make major cuts to federal spending, these tax credits could be on the chopping block.
But these tax credits are responsible for almost half of the legislation’s potential cuts to climate pollution, and as a climate organization, we can’t sit by and risk their repeal.
So we’re not! We’re digging in to defend America’s clean energy tax credits, and we’re doing it in every way we can — on Capitol Hill, over phone and email, and in person in communities across the country. (Even in major national media like the New York Times and The Guardian!)
The next few weeks are particularly critical, as we know that key committees are working on legislative language right now and trying to come to an agreement before the spring in-district work period later this month.
This is an important moment to send a strong message to Congress, so here’s a look at how we’re doing that.
Kicking things off on Capitol Hill
CCL’s conservative volunteers took the first real steps of this push in the 119th Congress during our 2025 Conservative Climate Leadership Conference and Lobby Day. After receiving communications training from CCL staff on March 4, 50 right-of-center volunteers visited 47 Republican offices on March 5.
Their primary ask in those meetings was for Republican members of Congress to preserve America’s clean energy tax credits. “As conservatives, we are passionate about the economic benefits of clean energy innovation and investment,” read a one-pager the volunteers brought to each office they visited.
“Clean energy tax credits included in the Inflation Reduction Act (IRA) have spurred unprecedented private investment, driven innovation, and created well-paying jobs across the country. […] Congress should protect these provisions to sustain momentum in America’s clean energy leadership.”
CCL’s efforts on Capitol Hill were noticed by the New York Times. In a March 17 article titled “The Republicans Pushing Trump to Save Biden’s Clean Energy Tax Credits,” the Times reported:
“Citizens’ Climate Lobby, a nonprofit group, held two days of events on Capitol Hill. After a day of preparations and training at a nearby Holiday Inn, dozens of the group’s staff and volunteers met with congressional staff to talk up the merits of the tax credits.”
The story continues, “Then, after a full day of meetings, the group held a reception at Barrel, a local bar, where three Republican members of Congress — Bruce Westerman of Arkansas, Mike Lawler of New York and Mariannette Miller-Meeks of Iowa — stopped by to receive the group’s ‘conservative climate award.’”
Our lobbying push was also noted by The Guardian. In a March 31 article titled “Clean energy spending boosts GOP districts. But lawmakers are keeping quiet as Trump targets incentives,” the Guardian reported:
“Citizens’ Climate Lobby, for instance, this month lobbied 47 Republicans on Capitol Hill calling on them to protect the tax credits, and is now asking its members to call their Republican representatives, focusing not on their climate benefits but on their potential to spur economic growth.”
Raising our voices around the country
After our strong start on Capitol Hill, CCL’s volunteers amplified the message by raising their voices nationwide in support of the clean energy tax credits.
During our national meeting on March 8, call attendees took a few minutes to send emails to Republican members of Congress reinforcing the need to protect the clean energy tax credits. From that quick action alone, we generated 1,753 messages to Republican offices.
Then, our Government Affairs team heard from congressional staff that key committees were beginning to work on the budget reconciliation bill in earnest, so it was time to ramp up our outreach. We shifted into high gear with phone calls, which signal to a congressional office that there’s even more urgency around this issue. Our calling push began, and as of this writing, we have generated 1,001 phone calls to Republican offices.
We’re doubling down on calls and working to run up that number through April 13, which is the last day before members of Congress head home for a spring in-district work period. If you have a Republican representative or senator and haven’t called them yet, pick up the phone and follow our script now.
Rallying the troops with grassroots outreach
It’s not just calls and emails — we’re hustling via hard copy, too. During our March meetings, CCL chapters began to generate hand-written letters to Congress about the clean energy tax credits.
Our March Action Sheet encourages volunteers to write letters that:
- Emphasize how their district or state has benefitted from the clean energy tax credits in the IRA, using details from our database
- Thank their representative if they are one of a growing number of Republicans speaking up in support of these clean energy tax credits
As we head into Earth Month, CCL chapters around the country will gather even more hand-written messages for Congress from people beyond their chapters. During grassroots outreach all throughout April — such as tabling at community events like Earth Day festivals — we’ll be using new fliers to educate and activate additional folks.
Fliers like this one from a district in Georgia will help us educate people about the local benefits of the tax credits. Find a flier for your district or state in our 2025 Tabling Toolkit.
We’ll also give people an opportunity to write their own message to Congress on a handout like this:
Print off your own handouts and get more guidance in our 2025 Tabling Toolkit. You’ll want a big stack of messages to help the next step of our advocacy pack a real punch.
Driving it home with district drop-offs
Once chapters have gathered an impressive stack of constituent letters, it’s time to plan a spring drop-off.
Our March Action Sheet explains that members of Congress (MOCs) will be in their district and state offices from April 21-25. Chapters can use this opportunity to drop off letters and other materials to their MOCs’ local offices, highlighting the local support for keeping the clean energy tax credits in place.
These local drop-offs are often a great way to get an office’s attention. By showing up on their home turf, we emphasize that this issue is something their constituents and voters truly care about and are paying attention to.
Behind-the-scenes bonus
In addition to all of the ways we’re mobilizing across the country, a select few CCLers are adding an extra layer of strategic outreach to relevant committee members.
The Republicans on the House Ways and Means Committee can have particular sway on the tax credit conversation, so with the guidance of CCL’s Government Affairs team, CCL liaisons to those members have been holding additional lobby meetings.
As the budget reconciliation process proceeds, CCL’s Government Affairs team will continue to tap certain CCL chapters and liaisons to apply pressure on the right members at the right time to make the most impact.
In short, we’re pulling out all the stops. The clean energy revolution — and our climate itself — deserves nothing less.

Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.
The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.
Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”

DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy crisis
ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.
‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.
‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home News. This message was echoed by UK business secretary Peter Kyle, who said “doubling down on renewables” was “essential” amid “regional instability”, according to the Daily Telegraph.
China’s climate plan
PEAK COAL?: China has set out its next “five-year plan” at the annual “two sessions” meeting of the National People’s Congress, including its climate strategy out to 2030, according to the Hong Kong-based South China Morning Post. The plan called for China to cut its carbon emissions per unit of gross domestic product (GDP) by 17% from 2026 to 2030, which “may allow for continued increase in emissions given the rate of GDP growth”, reported Reuters. The newswire added that the plan also had targets to reach peak coal in the next five years and replace 30m tonnes per year of coal with renewables.
ACTIVE YET PRUDENT: Bloomberg described the new plan as “cautious”, stating that it “frustrat[es] hopes for tighter policy that would drive the nation to peak carbon emissions well before president Xi Jinping’s 2030 deadline”. Carbon Brief has just published an in-depth analysis of the plan. China Daily reported that the strategy “highlights measures to promote the climate targets of peaking carbon dioxide emissions before 2030”, which China said it would work towards “actively yet prudently”.
Around the world
- EU RULES: The European Commission has proposed new “made in Europe” rules to support domestic low-carbon industries, “against fierce competition from China”, reported Agence France-Presse. Carbon Brief examined what it means for climate efforts.
- RECORD HEAT: The US National Oceanic and Atmospheric Administration has said there is a 50-60% chance that the El Niño weather pattern could return this year, amplifying the effect of global warming and potentially driving temperatures to “record highs”, according to Euronews.
- FLAGSHIP FUND: The African Development Bank’s “flagship clean energy fund” plans to more than double its financing to $2.5bn for African renewables over the next two years, reported the Associated Press.
- NO WITHDRAWAL: Vanuatu has defied US efforts to force the Pacific-island nation to drop a UN draft resolution calling on the world to implement a landmark International Court of Justice (ICJ) ruling on climate, according to the Guardian.

Captured
UK greenhouse gas emissions in 2025 fell to 54% below 1990 levels, the baseline year for its legally binding climate goals, according to new Carbon Brief analysis. Over the same period, data from the World Bank shows that the UK’s economy has expanded by 95%, meaning that emissions have been decoupling from growth.

Bristol’s ‘pioneering’ community wind turbine
Following the recent launch of the UK government’s local power plan, Carbon Brief visits one of the country’s community-energy success stories.
The Lawrence Weston housing estate is set apart from the main city of Bristol, wedged between the tree-lined grounds of a stately home and a sprawl of warehouses and waste incinerators. It is one of the most deprived areas in the city.
Yet, just across the M5 motorway stands a structure that has brought the spoils of the energy transition directly to this historically forgotten estate – a 4.2 megawatt (MW) wind turbine.
The turbine is owned by local charity Ambition Lawrence Weston and all the profits from its electricity sales – around £100,000 a year – go to the community. In the UK’s local power plan, it was singled out by energy secretary Ed Miliband as a “pioneering” project.
‘Sustainable income’
On a recent visit to the estate by Carbon Brief, Ambition Lawrence Weston’s development manager, Mark Pepper, rattled off the story behind the wind turbine.
In 2012, Pepper and his team were approached by the Bristol Energy Cooperative with a chance to get a slice of the income from a new solar farm. They jumped at the opportunity.
“Austerity measures were kicking in at the time,” Pepper told Carbon Brief. “We needed to generate an income. Our own, sustainable income.”
With the solar farm proving to be a success, the team started to explore other opportunities. This began a decade-long process that saw them navigate the Conservative government’s “ban” on onshore wind, raise £5.5m in funding and, ultimately, erect the turbine in 2023.
Today, the turbine generates electricity equivalent to Lawrence Weston’s 3,000 households and will save 87,600 tonnes of carbon dioxide (CO2) over its lifetime.
‘Climate by stealth’
Ambition Lawrence Weston’s hub is at the heart of the estate and the list of activities on offer is seemingly endless: birthday parties, kickboxing, a library, woodworking, help with employment and even a pop-up veterinary clinic. All supported, Pepper said, with the help of a steady income from community-owned energy.
The centre itself is kitted out with solar panels, heat pumps and electric-vehicle charging points, making it a living advertisement for the net-zero transition. Pepper noted that the organisation has also helped people with energy costs amid surging global gas prices.
