Disclosure Isn’t Just About Saving the Planet, It’s a Business Necessity Now, Says CDP Chief

BAKU, Azerbaijan—With more than 23,000 companies representing some $6.4 trillion of purchasing power reporting their emissions through CDP, the not-for-profit charity formerly known as the Carbon Disclosure Project is one of the leading names within the corporate sustainability space.

The U.K.-based nonprofit, which has been operating since 2000, was set up to encourage companies to disclose their environmental impact, including their carbon footprint, water usage and effects on forests and nature.

But amid a recent backlash against environmental, social and corporate governance initiatives, and as clean-energy stocks have slumped this year, concerns are growing over how important climate and sustainability reporting has become to companies. Greenhushing, the idea of companies pursuing climate plans without announcing them, has become a common practice, mainly because they fear being called out for greenwashing.

But, according to CDP Chief Executive Sherry Madera, these doubts should be put aside. A growing requirement for mandatory reporting, improved data and companies’ willingness to engage with supply chains are all signs that corporate engagement with climate and sustainability is still top of mind.

WSJ Pro Sustainable Business spoke to Madera at COP29 in Baku to discuss corporate engagement with climate and the push for company disclosures. The conversation has been edited for clarity and length.

WSJ: How will the Trump victory affect company policy around disclosures?

Madera: Climate change doesn’t start and stop with elections—and neither does climate action. Leading companies aren’t waiting to be told what to do; they’re already disclosing climate data because they know transparency equals opportunity. With 86% of the S&P 500 now voluntarily disclosing, it’s clear: U.S. companies aspiring to be global leaders understand that climate action is no longer optional—it’s a necessity. Regardless of shifting political landscapes, the competitive advantage is undeniable: those who act now will secure access to capital, reduce risks and lead in efficiency. The future isn’t just about compliance; it’s about staying ahead in a global economy where sustainability defines success. Any administration that cares about the economy has to care about data, science and climate.

WSJ: How can you encourage the private sector to disclose more climate and supply-chain data?

Madera: CDP is 24 years old. So the idea of surfacing information for investors, customers, economists and government regulators to take action on climate is not new for us. But it’s really come into its own in the last few years when disclosures became mandatory in many places around the world or have been signposted to be mandatory in the next few years.

I think that there’s a real shift in thinking about just setting targets versus now implementation. If we find ways of making sure that the money flows to more sustainable investment options, I think that really underpins what we as economies are trying to do.

There’s a lot of talk about the pushback, but the data doesn’t show that for us. So year-on-year we’re growing at about 24% voluntary disclosures from companies worldwide and that includes countries that don’t have a mandatory disclosure plan in place, i.e. the U.S.

Businesses are willing [to disclose] not because they necessarily have the primary directive of saving the planet but they’re willing to share information and to disclose data because it’s a business necessity now.

WSJ: How do you see corporate disclosures evolving over the next few years?

Madera: I see more mandatory disclosure is coming into place around the world and I think that’s a great thing. CDP has been encouraging this for decades so that’s great with the qualifier that says actually harmonising what is being asked for from a mandatory perspective is advantageous.

The reality is if you look at principles, frameworks, standards and data, the data is quite consistent and it’s just about making sure you’re mapping it and tagging that data so it doesn’t need to be written multiple times. And that efficiency I think is going to be really important because essentially every dollar you spend on reporting is a dollar you can’t spend on action and that doesn’t seem right.

WSJ: Do you see the role of the chief sustainability officer evolving and becoming more aligned with the chief financial officer? Would that be a good thing?

Madera : I think it’s a good thing. The CFO needs to be convinced that there is value in investing in servicing this information, in disclosing and being transparent. So being closely linked to other elements of the business, particularly the CFO who really has a say on the money that’s being spent.

CDP works with over 300 of the world’s largest supply chain owners and they’re very keen on looking at their scope 3. Not because they just want to report on it, but because they want to actually dig into the data so that they can work with their supply chain to find out ways that they can lower their emissions.

A great example of this is Walmart. So the Walmart gigaton project is something that CDP was closely involved in setting up and they came in and then the project was to lower emissions by a gigaton in about 15 years and they came in and achieved that six years early and they did that because they looked at the data from their supply chain and they actively engaged with those members and supply chain in order to be able to help them change their energy mix, helping them to find renewables as an alternative.

WSJ: With fewer companies expected to attend COP this year, how will you encourage more of them to disclose?

Madera: I have the luxury of speaking to many international corporations as well as private companies and the main thing they say to me is they want clear policy because that allows them to have very clear steer on how it is that they can build their business to be a sustainable business.

What I would hope we can see more of particularly starting now and going all the way through to COP30 in Brazil, is that deeper engagement of companies that are working within these jurisdictions to be able to know really clearly what it is that they are going to be asked to contribute to those national goals and be an important part of them.

WSJ: Do governments influence company climate policy?

Madera: In 2024, I think over 70% of the world’s population has gone, or will go to the polls and obviously climate isn’t the only issue, but it is one of the issues in various places around the world.

Businesses do want clear signposting in terms of policies and in terms of government support or encouragement. More companies are continuing to disclose to ensure that they’re competitive.

But they’re also tending to be quieter about it than they were a couple of years ago. Before they were proudly screaming from the rooftops that they were transparent, and they were setting targets and they were making progress and these are their transition plans. What we’re finding is that they’re disclosing the data, but they’re doing so with less fanfare and less engagement with us to try and promote themselves.

So they’re keeping their heads below the parapets, it doesn’t mean that the data is not there and it’s not moving.

Former New Hampshire Gov. Chris Sununu delivered a warning to Treasury Secretary Scott Bessent during a recent visit to Washington: Already-high airfares will surge if the war in Iran doesn’t end soon.

Sununu, a Republican who represents some of the biggest airlines as president of the industry group Airlines for America, has for weeks sounded the alarm to Trump administration officials about the economic fallout from high jet fuel prices. The war, Sununu has argued, must come to a close soon, or things will get worse.

Administration officials have gotten the message.

Privately, President Trump’s advisers are increasingly worried that Republicans will pay a political price for the rising fuel costs, according to people familiar with the matter. Many of those advisers are eager to end the war, hoping prices will begin to moderate before November’s midterm elections.

The fallout from the U.S.-Israeli attack in late February has slowed traffic through the Strait of Hormuz, a vital shipping lane, triggering a sharp increase in oil, gasoline and jet-fuel prices.

That means consumers are grappling with high costs ahead of the summer travel season, as they consider vacation plans.

Sixty-three per cent of Americans said they put a great deal or a good amount of blame on Trump for the increase in gas prices, according to a new poll conducted by NPR, PBS and Marist.

More than 8 in 10 Americans said struggles at the gas pump are putting strain on their finances.

Jet-fuel prices roughly doubled in a matter of weeks after the war began, and they have remained high. Airlines have said that will add billions of dollars of additional expenses this year, squeezing profit margins.

U.S. airlines spent more than $5 billion on fuel in March—up 30% from a year earlier, according to government data.

Carriers have been raising ticket prices, hoping to pass the cost along to consumers, and they are culling flights that will no longer make money at higher price levels.

In March, the price of a U.S. domestic round-trip economy ticket rose 21% from a year earlier to $570, according to Airlines Reporting Corp., which tracks travel-agency sales.

So far, airlines have said the higher fares haven’t deterred bookings and they are hoping to recoup more of the fuel-cost increases as the year goes on.

Earlier this week, Trump said the current price of oil is “a very small price to pay for getting rid of a nuclear weapon from people that are really mentally deranged.”

Secretary of State Marco Rubio told reporters that if Iran got a nuclear weapon, the country would have more leverage to keep the strait closed and “make our gas prices like $9 a gallon or $8 a gallon.”

Trump has taken steps in recent days to bring the war to an end. Late Tuesday, the president paused a plan to help guide trapped commercial ships out of the Strait of Hormuz, expressing optimism that a deal could be reached with Iran to end the conflict.

Crude oil prices fell below $100 a barrel on Wednesday, after reports that Iran and the U.S. are working with mediators on a one-page framework to restart negotiations aimed at ending the conflict and opening the strait.

Sununu said Trump administration officials are conscious of the economic fallout from the war: “They get it…and I think that’s why they’re trying to get through the war as fast as they can.”

But he cautioned that it could take months for prices to return to prewar levels.

“Ticket prices won’t go down immediately” after the strait is fully reopened, Sununu said. “You’re looking at elevated ticket prices through the summer and fall because it takes a while for the prices to go down.”

Since the initial U.S.-Israeli attack in late February, Sununu has met in Washington with National Economic Council Director Kevin Hassett, representatives from the Transportation Department and senior White House officials.

A White House official confirmed that Hassett and Sununu have discussed the effect of increased fuel prices on the airline industry. The official said the conversation touched on how the industry can mitigate the impact of high jet fuel prices on consumers.

“The president and his entire energy team anticipated these short-term disruptions to the global energy markets from Operation Epic Fury and had a plan prepared to mitigate these disruptions,” White House spokeswoman Taylor Rogers said, pointing to the administration’s decision to waive a century-old shipping law in a bid to lower the cost of moving oil.

Rogers said the administration is working with industry representatives to “address their concerns, explore potential actions, and inform the president’s policy decisions.”

A Treasury Department spokesman pointed to Bessent’s recent comments on Fox News that the U.S. economy remains strong despite price increases. The spokesman said Treasury officials have met with airline executives, who have reaffirmed strong ticket bookings.

“We’re cognizant that this short-term move up in prices is affecting the American people, but I am also confident, on the other side of this, prices will come down very quickly,” Bessent told Fox News on Monday.

The war has already contributed to one casualty in the industry: Spirit Airlines. Company representatives have said they were forced to close the airline because the sustained surge in jet-fuel prices derailed the company’s plan to emerge from chapter 11 bankruptcy.

The Trump administration and Spirit failed to come to an agreement for the company to receive a financial lifeline of as much as $500 million from the federal government.

Transportation Secretary Sean Duffy has argued that the Iran war wasn’t the cause of Spirit’s demise, pointing to the company’s past financial struggles, as well as the Biden administration’s decision to challenge a merger with JetBlue.

Other budget airlines have also turned to the federal government for help since the U.S.-Israeli attack. A group of budget airlines last month sought $2.5 billion in financial assistance to offset higher fuel costs, and they separately wrote to lawmakers asking for relief from certain ticket taxes.

Sherry Madera, in Baku for COP29, says more companies are reporting on climate than ever, despite a pushback against ESG.

Administration officials have spoken to the airline industry, which has voiced concerns about the rising costs.
