Top 10 Must-See Speakers at Sustainability LIVE Net Zero

Sustainability LIVE Net Zero Takes Place in London and Virtually on March 6-7
From AWS to Henkel, P&G to General Motors, sustainability executives from leading companies will share their expertise at Sustainability LIVE Net Zero

We will be the first to admit that sustainability can often be confusing.

Companies of all shapes and sizes struggle to get to grips with an ever-evolving regulatory landscape, game-changing technologies, and strategies for success.

That’s why events like Sustainability LIVE Net Zero, taking place in London on 6-7 March, are absolutely essential for executives looking to improve their understanding of the latest trends and developments in sustainability and ESG.

Where else could you hear insights from the sustainability champions at some of the world’s biggest organisations in a series of keynotes, roundtables, fireside chats, workshops, and networking sessions all under one roof?

With sessions across two stages on both days, the hardest decision will be which ones can you afford to miss. But fear not. Whether you are joining the event in-person or streaming live around the world, every session will be available to watch on demand.

We don’t have favourites, but here we select 10 must-see speakers from Sustainability LIVE Net Zero.

As one of the world’s most influential players in the EV movement, Kristen Siemen will join her automotive peers in an all-woman panel on day one of the show to discuss the future of electric cars in a net-zero world.

Kristen, who began her career at GM in 1994 and previously worked as Executive Director of Global Energy Strategy, has been instrumental in rolling out programmes and technologies to accelerate GM’s zero-emission targets.

Home to brands including Buick, Cadillac and Chevrolet, General Motors unveiled its ambitious net target in 2021 – to be carbon neutral in global products and operations by 2040, alongside an aspiration to eliminate tail-pipe emissions from new US light-duty vehicles by 2035.

And the US$156.7 billion revenue business is on track to achieving these goals, accelerating its transformation to EVs and AVs, and committing more than US$35 billion to transform manufacturing facilities to an all-electric future.

Speaking to Sustainability LIVE New York in 2023, Kristen said GM was committed to being part of the transition to an all-electric future and this includes helping to make the charging infrastructure transition happen.

“We have committed US$750 million through 2025 to expand charging for residences, workplaces and public areas – and also support stronger EV public policy to make this EV experience for all.”

Passionate too about promoting DEI across the business, Kristen was instrumental in creating GM’s career re-entry programme and introducing the Women Allied Programme.

In recognition of her sustainability effort, Kristen was named among the top 25 women in sustainability globally in the Top 100 Women in Sustainability list.

Head of Sustainability


Session: Day 1 (March 6) 12pm GMT, Stage 2

Fredrika Klarén is Driving Sustainability at Polestar Since 2020

Armed with more than a decade of dedicated sustainability experience across fashion, retail and now EVs, this month’s Sustainability Magazine cover star, Fredrika Klarén is driving the sustainability agenda at pure-play EV maker Polestar.

Passionate on purpose, Fredrika lives and breathes sustainability, not just dedicating her career to the net zero cause but in her personal life too – becoming an “EV owner very early on”, she told Sustainability Magazine in a recent exclusive interview.

As well as driving sustainability at Polestar, where she works to reduce the carbon footprint of the brand’s EVs and collaborates with research partners to create climate-neutral materials, Fredrika is driving the industry forward.

Polestar is more than a maker of EVs, Fredrika tells Sustainability Magazine – it is facilitating connections and innovations to support an ecosystem of mobility.

A regular speaker on the sustainability circuit and attendee of COP, including COP28 in Dubai, Frederika is outspoken about the state of play in automotive and passionate about leading the industry forward in a collective effort towards decreasing emissions from passenger vehicles.

“In our pathway report, we show that to stay below 1.5 degrees, we have to see that 100% of sales are EVs by 2032,” she says.

Frederika will bring her expertise and perpective on the future of electric cars to an expert all-female panel on day one of the show – where, alongside EV-focused equals like Rivian CSO Anisa Kamadoli Costa and GM CSO Kristen Siemen, she will explore the challenges, solution and opportunities of an all-electric future.


Anisa Kamadoli Costa

Chief Sustainability Officer

No stranger to sustainability strategy, Anisa previously spent nearly two decades at Tiffany & Co., where she developed and led the company’s industry-leading, metrics-driven ESG agenda, as well as strategically aligning the firm’s philanthropy and its sustainability priorities.

Under her leadership, Tiffany delivered consistently high sustainability ratings, ranking fourth on Barron’s Most Sustainable Companies list in 2020.

Bringing her expertise to Rivian in April 2022, Anisa is now driving the integration of ESG into all business decisions, as the company looks to achieve its Impact Goals.

“As a mission-driven company founded to accelerate the transformation to clean transportation, we are not comfortable allowing emissions to shift from tailpipes to power plants,” shares Anisa.

“We take our responsibility seriously to drive system-wide decarbonisation.”

As well as overseeing accounting of carbon emissions and other sustainability metrics, Anisa serves as the President and Trustee of the Rivian Foundation.

An experienced philanthropic executive, she is driving alignment between Rivian’s sustainability priorities and the Rivian Foundation’s grant-making dedicated to high-impact environmental initiatives.

Virginie Helias

Chief Sustainability Officer

Procter & Gamble

Session: Day 2 (March 7) 10am GMT, Stage 1

Virginie Helias Brought the Sustainability Agenda to P&G

A celebrated figure in the global sustainability landscape, Virginie Helias is widely credited with bringing sustainability to P&G.

Helias’ journey to environmental enlightenment began in 2005, when working in marketing in P&G’s fabric care business, she was profoundly impacted by Al Gore’s 2005 documentary, An Inconvenient Truth.

Upon discovering that 80% of the carbon footprint associated with detergent products was linked to the washing machine’s temperature use, Helias realised that cold water washes could be a pivotal sustainability initiative.

And so began an environmental journey that would see Helias embed sustainability within P&G’s business model.

In 2011, Helias pitched to then-CEO Bob McDonald a unique role for herself, as Sustainability and Digital Director for Household Care in Europe. This was the first of four sustainability portfolios Helias would go on to hold, as she looked to turn P&G towards a more sustainable future.

Which is exactly what Helias has done. From the innovative launch of a new Head & Shoulders bottle made from 25% recycled beach plastic at the WEF in Davos in 2017, to taking the sustainable lead as CSO in 2019, Helias has made quite the environmental mark at P&G.

Among achievements in the last five years, Helias has overseen P&G’s sign-up to Amazon’s Climate Pledge, actioned the company’s ambitious SBTi-verified targets in 2030 and 2040, and led the multinational to plastic waste neutrality.

Lauded for her many sustainability successes, Helias was named number six in Sustainability Magazine’s prestigious Top 100 Women in Sustainability 2023.

In a keynote titled Sustainability & Superiority: A Winning Combination on day two of the Sustainability LIVE Net Zero (March 7, 10am), Helias will bring her passion and wisdom to stage 1 where she will share the strategies P&G has embraced in its journey to net zero 2040 – from innovation in materials to tackling waste.

Armed with 30 years of experience as a technologist, from software to data centres, and a passion for sustainability – having studied climate and environmental science in the 1980s – Thomas Blood is now fusing the two.

As Commercial Sector Sustainability Leader at AWS EMEA, Blood works with clients using AWS and the cloud to realise and accelerate their sustainability ambitions and goals.

As Blood told Sustainability Magazine in an exclusive interview in January: “There are some estimates that believe that sustainability could be a US$12 trillion business on its own. So, there's this beautiful convergence of a great need in the world and technology being able to address some of that need.”

Taking inspiration from his work at AWS, and the clients he has worked with, Blood has penned a book (‘Reaching Cloud Velocity’) alongside xxx Jonathan Allen that explores lessons learned and knowledge gained – to help leaders accelerate sustainability through the AWS cloud.

With the sustainability conversation moving from strategy implementation to pushing for net-zero results, Blood believes the cloud has a huge role to play in that accelerated journey – providing customers with the mean to scale ideas quickly to maximise impact.

Blood will bring his expertise and passion to the London stage on day two (March 7, 12.55pm) with a keynote.
