Spotlight on Climate Impact Partners
The Women in Sustainability panel is taking place in association with Climate Impact Partners (CIP).
CIP aims to use carbon finance to drive projects that can transform the global economy, improve health and livelihoods and restore the environment.
It is committed to delivering one billion tonnes of carbon dioxide removals.
Its CEO, Sheri Hickok, will deliver the opening statement and appear on the panel itself.

She has worked on a global scale, helping companies with their climate solutions to drive the transformation to a low-carbon economy.
Sheri said on LinkedIn: “At CIP, women aren’t just part of the story – they are leading it! 60% of our C-suite are women and more than half of our global team is led by women across the business. Their leadership powers the outcomes we deliver for clients, communities and climate.
“And beyond our walls, the work this team delivers is improving lives for women and girls around the world… women accessing cleaner cooking solutions, safer homes, renewable energy, improved health and education and expanded economic opportunity through the projects we support. Their stories remind us that climate action is also gender equity in action.”
Dr Márcia Balisciano, Chief Sustainability Officer, RELX
Márcia will share expertise from her role at RELX on the panel.
She has been with the company for more than 23 years, creating and running the company’s global corporate responsibility function.
She leads an international team, working closely with colleagues at all levels to ensure that sustainability and corporate responsibility are embedded throughout the organisation.
Márcia says: “The majority of the electronic delivery of our products and services is happening in the cloud. So we got together with peers and academics to look at the methodology that our part of media should be using to calculate these emissions. We’re stronger when we group together to discuss critical issues.”
Vaishali Nigam Sinha, Co-Founder & Chairperson, Sustainability, ReNew
Vaishali plays an important role in positioning ReNew as a global ESG leader, leading its net zero agenda and sustainability strategies.
She leads the ReNew India Initiative, which has reached remote regions, positively impacting more than 1.5 million lives with CSR programmes.
She has received honours for her leadership, including Fortune India’s 50 Most Powerful Women and Business Insider’s 100 People Transforming Business.
Vaishali says on LinkedIn: “Climate action that ignores the most vulnerable isn’t ambition. It’s incompleteness.
“Women and children face the sharpest edge of climate change. Yet they remain the most underrepresented in designing the response. At ReNew Foundation, we believe that has to change not as a gesture, but as a strategy.
“When women gain economic independence, families become more resilient. Communities make better decisions. The evidence is clear and the logic is simple: you cannot build a climate-secure future while leaving half the population on the margins of it.”
