Who we are

Our history

Quadrature Climate Foundation (QCF) was established in 2019 by the founders of Quadrature Capital, Greg Skinner and Suneil Setiya. Initially, our founders were passionate about supporting causes that addressed poverty, inequality and human suffering. In 2018, they came to understand the way the climate crisis superimposed onto these challenges, undermining efforts to combat famine, support refugees, and manage natural disasters. This led them to focus the work of the foundation on efforts to combat climate change, the most urgent challenge of our time. 

In 2023, QCF embraced a mandate to tackle the ‘New Climate Reality’. This approach acknowledges that while rapid decarbonisation is essential, it must now be complemented by efforts to remove greenhouse gases from the atmosphere, and those that address the impacts of climate change on vulnerable communities. 

Our ‘big tent’ philosophy fosters diverse engagement to accelerate solutions. Emphasising a truly science-based approach, we use evidence from varied sources to challenge conventional perspectives. Returning to our foundational goals, we prioritise creating a climate-resilient future for the world’s most vulnerable people. 

Our team

Our team of more than 30 employees is made up of scientists, policymakers, lawyers, advocates and those from the corporate and financial sectors we engage with, all driven by a shared commitment to discover and implement critical solutions.

Our decision-making and actions are guided by our commitment to be:

  • Collaborative: we know we cannot end the climate crisis alone and seek out new allies and partnerships across everything we do.
  • Humble: we recognise our strengths and blind spots. We seek feedback, value others’ ideas, and reflect on our own biases.
  • Brave: we are unafraid to explore difficult or contentious areas or work on overlooked solutions.
  • Objective: we make evidence-based decisions, integrating diverse knowledge from various disciplines and stakeholders to challenge existing assumptions.
  • Driven: we are committed to delivering at the pace commensurate with the urgency of the climate crisis. We will work through ambiguity, and go the extra mile to achieve collective impact.
