Sustainable Travel International unveils new tool for calculating and offsetting travel emissions

Sustainable Travel International has launched a new online carbon footprint calculator that promotes climate-friendly travel by enabling users to measure and offset their travel emissions. This new tool is designed specifically for travel activities including commercial and charter flights, vehicles, cruises, liveaboards, and yachts.
For the past two decades, Sustainable Travel International has fostered environmentally and socially responsible travel, working in more than 100 destinations and engaging governments, companies, and consumers in sustainable practices. Sustainable Travel International is recognized as a leading organization for climate action in tourism, having supported more than 50,000 travelers and businesses in mitigating their carbon footprint and being named the best carbon offset provider for travel by Investopedia, Treehugger, and EcoWatch.
“Travel is fueled by our desire to discover the planet’s natural and cultural wealth. It’s those unparalleled experiences, like snorkeling over a colorful coral reef or sailing between towering ice sheets, that make travel so fulfilling – but climate change puts all of this at risk. If we don’t act now, these destinations and experiences will cease to exist,” said Paloma Zapata, CEO of Sustainable Travel International. “Travel is often viewed as part of the problem, when really it should be part of the solution. We believe that this new calculator has the potential to stimulate climate action by channeling investment to projects that pave the way for a net zero future.”
Over the past two years, the COVID-19 pandemic shifted the traveler mindset, with consumers becoming more conscientious about their impacts on destinations and the planet. According to research conducted by Booking.com, more than two-thirds of travelers (69%) are now committed to reducing or offsetting the carbon footprint of their trip.
Sustainable Travel International’s new carbon calculator makes it easy for travelers to do just this. The calculator was completely redesigned and rebuilt to account for nearly all the high emissions aspects of travel, utilizing the latest methodologies for travel footprinting while maintaining a balance between scientific accuracy and ease of use. Users simply enter their travel activities – for instance, a round-trip flight from Chicago to Miami and a 5-day cruise – and the calculator will automatically compute their carbon footprint. The user can then choose to purchase carbon offsets, which typically cost around $5 to $30 for a trip.
The offset dollars help fund carbon reduction projects around the world, such as forest conservation and clean energy initiatives, that are scientifically proven to mitigate climate change. Sustainable Travel International carefully vets all projects to ensure they meet the most rigorous standards for carbon offsetting, such as the Gold Standard and Verified Carbon Standard (VCS), and conducts its own, additional due-diligence on projects to ensure the utmost level of integrity and impact. Sustainable Travel International only supports high-quality projects that contribute to the UN Sustainable Development Goals (SDGs) and deliver benefits beyond climate mitigation by creating local jobs, strengthening indigenous land rights, improving sanitation, protecting endangered species, and more.
Sustainable Travel International also offers business solutions through their Climate Rangers Program, including carbon footprint measurement, climate action planning support, business carbon offset programs, and employee climate education.

Diving into the World’s Fastest Tidal Rapids

In the mystical waters just north of Vancouver, Canada lies a narrow channel called the Skookumchuck Narrows, or simply “The Skook.” It’s a hidden gem in the Salish Sea that boasts a unique spectacle – a tumultuous dance of tides and currents that draws adventurers and spectators from far and wide.
Imagine this: a channel so narrow and shallow that a single tide can unleash an astonishing 200 billion gallons of water, creating a tumultuous display of standing waves, whirlpools, and currents surging at 16 knots (18 mph or 30 kph). Such speeds may seem mild when driving a car, but the erratic water is a different ballgame. Skookumchuck Narrows is a contender for the title of the world’s fastest tidal rapids, rivaled only by Nakwakto Rapids further up the British Columbia coast.

All photos were captured with a Nikon Z6 in an Ikelite underwater housing with Sea & Sea YS-D3 Mark II strobes.
But there’s a twist – this aquatic battleground isn’t just for adrenaline seekers; The Skook is an oasis for life beneath the waves. April 2023 marked a rare convergence of perfect conditions: a celestial alignment allowing divers to witness The Skook in all its glory. And who better to guide this daring expedition than Porpoise Bay Charters, a family-run venture led by the seasoned Kal Helyar and Ann Beardsell?
Raging currents = an abundance of life
The allure lies not in the danger but in the vibrant marine ecosystem fueled by the relentless currents. Ocean currents act as nature’s turbochargers, transporting nutrients that transform places like Skookumchuck Narrows into underwater havens with colorful life thriving amidst the rocky terrain.
It’s important to debunk the myth that this is a reckless plunge into chaos. Diving The Skook is not about courting danger but choosing the right moment: at slack when the tide turns, the water experiences minimal movement, and the currents are a mere 4-5 knots. Picture this – a scuba diver slipping gracefully between tidal changes, maneuvering with precision as the water changes its course and gradually picks up speed. Timing is everything, and finding the rare dates when daylight piercing through the emerald-green water coincides with navigable water conditions is critical. April 2023 granted us a mere handful of these golden days of nature’s alignment for the first time in four years.
Entering the abyss
As our vessel, under the watchful eye of Captain Kal, approached the infamous Skookumchuck rapids, a tangible excitement filled the air. These cold-water adrenaline-filled dives are the scuba diving equivalent to scaling Everest. The unpredictability of The Skook, where currents can whisk you in any direction, demanded respectful caution from our experienced salty crew.
With a reassuring smile, Captain Kal dismissed the notion of a toilet bowl experience, where divers are pulled in a circular direction by the currents as if flushed down a toilet. He emphasized that they only dived during an easy drift in the current, which was hard to fathom possible in such treacherous waters. Approaching the narrowest section of the channel, where the current was fastest, Kal’s experienced eyes scanned for the telltale signs of slack tide. Tidal ripples slowed, and we entered the water in the few precious minutes within the next year when it was possible to witness Skookumchuck in all its sunny glory.
As we descended into the underwater world, a mysterious algal bloom cast a dark green haze, unveiling a breathtaking palette of colors below. Bright red and pink anemones, neon orange encrusting sponges, and deep purple ochre sea stars adorned the rocky canvas, showcasing nature’s artistic prowess.
Surrendering to the sea
Descending further, we felt the force of the tide, like a river yet to subside. Gripping onto rock holds and kicking into the current, we felt like underwater rock climbers. Adjusting our underwater camera settings and getting comfortable with the flow of the water, we marveled at the transformation of the underwater landscape. Slabs of rock, once pounded by the current, now hosted a vibrant community of marine life.
After a mesmerizing twenty minutes of relatively gentle water, the current intensified, signaling the roller coaster drop ahead. We surrendered to neutrality, letting the current guide us along the wall. Boulders and back eddies added a touch of unpredictability; with trust in our abilities and Captain Kal’s promise of a safe pickup, the thrill was exhilarating rather than menacing.

A group of invertebrates are protected from the fast current by a crevice; the rest of the rocks sandblasted clean by the fast water.
As the current ebbed, we found ourselves in a tranquil cove adorned with green sea urchins, marking the end of our underwater odyssey. The Skook had shown us its splendor: a delicate balance of chaos and life beneath the surface – leaving us with memories as vivid as the colors we witnessed.
