John Kerry, the U.S. special presidential envoy for climate, was called out earlier this year for not practicing what he preached. When flying around the world warning of the dangers of carbon emissions, Kerry inflicted upon the environment a carbon footprint 300 times larger than the average American's in a single year. Facing continued scrutiny, he will now fly commercial — at least once.

Going where?

The State Department indicated that Kerry traveled to London in late October to participate in an onstage conversation with Chatham House about U.S. international efforts to battle so-called climate change.

From the U.K., the carbon-conscious climate envoy will fly to the United Arab Emirates.

After discussing "regional climate action" with Near Eastern oil barons and their beneficiaries, Kerry will head to Egypt. There he will lead the U.S. delegation to the 27th United Nations Climate Change Conference (COP27) in discussions about possible U.S. reparations to the third world for its bad weather.

The COP27 climate change conference will take place Nov. 6-18 in the Egyptian resort town of Sharm el-Sheikh, where air conditioning runs nonstop.

Going how?

A State Department spokesman told Fox News Digital that Kerry would be flying to COP27 in a commercial jet. It is presently unclear whether his flights to the U.K. and to the Emirates will similarly be on commercial airliners. Those details may soon come to light.

Judicial Watch filed a Freedom of Information Act lawsuit last week against the State Department for details of Kerry's office and its travel costs.

Tom Fitton, the president of Judicial Watch, stated, "The American people have a right to know what John Kerry is up to, what we're paying him to fly around the world, and who we pay to actually work for him."

Fitton added that Kerry was likely responsible for "more carbon distribution than anything else they are complaining about."

TheBlaze previously reported that Kerry had flown over 180,000 miles when conducting his affairs as climate envoy, despite having access to high-quality teleconferencing technologies with which he could remotely engage foreign dignitaries.

Analysis conducted by the Washington Free Beacon — of fuel consumption, mileage, travel plans, and projected exhaust figures — showed that Kerry was responsible for the emission of over 9.54 million pounds (4,772 tons) of carbon since March 2021.

By way of comparison, the average American's yearly carbon footprint is 16 tons.

The accounting for these figures took into consideration Kerry's 75 official travel announcements and destinations as well as his plane's average carbon dioxide production per mile, approximately 53.3 pounds.

Sen. Josh Hawley (R-Mo.) thought this revealed the Biden administration's hypocrisy, telling Fox News Digital, "Joe Biden launched his war on American energy on his first day in office, shutting down domestic energy production and making us reliant on our enemies."

"While Americans are struggling to afford gas and being lectured about ‘transitioning’ their energy use, Biden’s cabinet is jetting around the world wasting the same fossil fuels they say they want to ban," added Hawley.

Sen. Dan Sullivan (R-Alaska) was even more forceful and direct in his critique, saying, "Smug, hypocritical, hammering middle-class families, and now this: John Kerry is one of the single biggest polluters and [greenhouse gas] emitters in the world. ... Once again, I call for him to resign."

Between carbon-heavy climate conferences, Kerry's personal jet also generated some significant emissions.

The Kerry family's private jet, a Gulfstream GIV-Sp, belched over 325 metric tons of carbon dioxide between January 2021 and July 2022.

The executive director of the energy advocacy organization Power the Future, Daniel Turner, told Fox News Digital that "John Kerry and the climate hypocrites who run the green movement ... refuse to voluntarily live how they want the rest of us to be forced to live."

Kerry previously defended his use of a private jet to pick up a climate change leadership award in Iceland, saying, "If you offset your carbon, it's the only choice for somebody like me who is traveling the world to win this battle."

Carbon offsetting involves paying off other people or organizations to reduce their emissions so you don't have to account for or adjust your own.

Kerry noted further, "What I'm doing, almost full time ... is working to win the battle on climate change."

Winning is not just a matter of killing American jobs and losing energy independence. For Kerry, winning also means removing carbon dioxide from the atmosphere, including the 5,000 tons he recently put there.

Biden's climate envoy says he's serious. Kerry told CBS News last winter that "to avert the worst consequences of climate crisis ... we have nine years left ... There is no room for BS any more."

Going why?

According to conference president Sameh Shoukry, the purpose of this year's COP27 gathering is to take "meaningful and tangible steps" to enforce the 2015 Paris climate accord.

The AP reported that some activists hope to see commitments to addressing "loss and damage," whereby wealthy nations agree to pay reparations to developing nations that have suffered problems resulting from nasty weather.

Ani Dasgupta, the CEO of globalist nonprofit World Resources Institute, wrote, "Developed countries should provide funds for addressing losses and damages not because of legal liability, but because supporting vulnerable countries is the right thing to do."

U.N. Secretary-General António Guterres recommended that Western nations confiscate profits from oil and gas companies and redistribute them to developing nations affected by bad weather.

Kerry has not yet committed the U.S. to these proposed reparations, but has indicated a willingness to discuss the possibility.

Kerry stated, "The U.S. recognizes that increased efforts must be made to avert, minimize, and address loss and damage associated with the adverse impacts of climate change."

Axios reported that Kerry's promises are constrained by domestic politics and that a Republican-led House could prevent the Biden administration from diverting American funds toward international climate indulgences.
