Edit, 20 September 2021: The Round Britain Climate Challenge is on hold following the devastating news shared by Conservation Without Borders on Sunday 19 September that Sacha Dench and Dan Burton were involved in a paramotor accident in the Highlands. Dan tragically died as a result of the accident and Sacha sustained serious but not life-threatening injuries. Our thoughts are with Dan’s family and loved ones at this heart-breaking time, and we send our well-wishes to Sacha for a safe and speedy recovery.

Edit, 27 October 2021: The documentary "Joanna and The Human Swan" will air on ITV at 9pm on 1 November 2021.

Edit, 8 December 2021: Conservation Without Borders have confirmed that Sacha is making great progress in her recovery.

The Round Britain Climate Challenge, which counts leading independent and chartered accountancy firm Johnston Carmichael amongst its sponsors, has received backing from a prominent British television icon.

Joanna Lumley, actor, presenter and activist, has announced her support for Sacha Dench – known as the Human Swan – in her intrepid circumnavigation of mainland Britain by electric paramotor.

Joanna Lumley came across Sacha’s planned climate expedition through a crowdfunder call out for the expedition and was inspired to try and become more involved. Joanna decided to call Sacha, and as a result of that conversation Joanna will be following Sacha and meeting up with her at various places around the country as Sacha completes the Round Britain Climate Challenge. They will be filming a documentary together for ITV as the journey progresses, in which Joanna will be the presenter.

As sponsor of the Round Britain Climate Challenge, Johnston Carmichael has been closely following Sacha’s journey so far. The firm has also been participating in the Conservation Without Borders and Count Us In Guinness World Record attempt, with staff and partners taking steps to reduce their carbon footprint in an effort to set the record for the most people pledging climate action in one month.

Mark Stewart, Head of Energy, Infrastructure and Sustainability at Johnston Carmichael, said: “With roots in local communities across 13 UK locations and over 16,000 clients across the country, we are committed to supporting the communities in which we live and work, and helping position Scotland as a global hub for sustainable infrastructure and renewable energy investment.”

Joanna Lumley said: "Sacha Dench’s adventures are stories you can only dream of - facing down all barriers and blessed with the courage of a lioness she literally soars into history books, and inspires everyone who has the luck to follow her phenomenal challenges. Sacha is clawing attention towards the greatest crisis mankind has faced in recorded time. Her journey is going to be irresistible and I shall be following her, on charts and in person, I am so proud to support her: with your help we shall be the wind beneath her wings."

Sacha added: "Joanna’s call came totally out of the blue and it’s just fantastic that Joanna is so supportive of this mission to look at how climate change is affecting different regions of the country – and highlight all the amazing things that individuals, community organisations and companies are doing to combat it. We want to get everybody involved and one of our aims is to get 140,001 people to take personal climate action between 18 June and 17 July through Count Us In – so please sign up now! If we achieve this number we’ll get a Guinness World Record too!

I am so looking forward to Joanna joining me to meet many of the inspiring people along the route."

The progress of Sacha’s journey can be followed on the Conservation Without Borders website, and Johnston Carmichael is also sharing updates on its LinkedIn, Facebook, Twitter and Instagram pages.
