About us & why we formed sustain:able
Updated: Mar 23
- Energy & Water -
The two most essential things our society relies on.
We formed sustain:able because we're passionate about finding a balance to the energy trilemma and ensuring everyone has access to clean water.
The biggest and most complex problem the world is working on today is that of achieving a low-carbon economy while striving to maintain energy balance:
security of energy supply
affordability and equity
environmental sustainability
Water must be the fourth focus in order for us to achieve a stable, equitable and prosperous future for our children and grandchildren.
Everything we want to achieve for our world - lifting communities from poverty, food security, education, equality, environment - stems from clean, reliable and affordable energy and water.
As mums to young families, we want a better future for them - it's as simple as that.
- over 50 years combined experience -
We have a background in geoscience and engineering and bring over 50 years combined experience in the global energy and extractive industries.
We understand addressing climate change is not as simple as "turning the taps off" and ceasing oil & gas production. A rapid, but also fair and equitable energy transition is needed if no one is to be left behind.
Problem solving and seeking to understand the complex interplay of diverse facets of a problem are part of who we are.
Our unique scientific knowledge, industry experience and innovative problem solving can help you spot the opportunity to be sustainable and authentic within your core business.
Co-Founder - Dr Rachel Gavey, Bath
Since relocating to the UK from New Zealand with her young family, Rachel's focus with her work is to encourage collaborative workflows between companies and individuals in order to develop ideas that can make a real impact on the increased and sustainable production of clean energy and water.
Technology forms the centre of all Rachels’ projects; she is incredibly passionate about the smart use of technology for solving problems, especially when those problems relate to the energy transition.
Rachel has a PhD in Marine Geology, a BSc in Geological Oceanography and many years experience working in a variety of roles across the energy industry around the globe. As a Board Director of the Scottish Energy Forum, she places herself at the forefront of the most topical energy discussions.
Co-Founder - Dr Rosalie Constable, Cambridge
Rosalie believes it’s critical to understand the complex role energy plays in our society and seeks to balance energy security, equality and sustainability. The "Energy Transition" is just that - a transition - a time during which we must transform our projects and practices to be more sustainable.
Rosalie has a PhD in Earth Science and over 18 years’ working in various technical and management roles in the energy industry. In 2021, Rosalie completed the University of Canterbury Energy InTIME© course in Transition Engineering (Interdisciplinary Transition Innovation, Management and Engineering - InTIME©). This workflow is an interdisciplinary approach to finding innovative, practical solutions for a more resilient and sustainable future. And in 2022 she completed ISO 14064-1 certification for Greenhouse Gas Emissions Accounting.
Rosalie's work in Africa alongside local communities highlighted to her the incredible importance and responsibility of providing clean, reliable and affordable energy and water to all - the drivers for her work at sustain:able.
She meets each challenge with an enthusiasm for problem solving and a unique perspective and breadth of experience gained from working on successful energy projects across the world.
Dr Gabby Watson, Manchester
Having previously focussed her studies on oil and gas exploration Gabby has shifted focus to sustainable technologies and emerging green energy sources. Specialising in information gathering and report writing, Gabby helps bring together knowledge on the latest sustainability strategies and innovations.
Gabby has a PhD in Faults and Fluid Flow from the University of Canterbury, a master’s degree in Petroleum Geology from the University of Manchester and a bachelor’s degree in Geology from Imperial College London. In 2022, Gabby completed ISO 14064-1 certification for Greenhouse Gas Emissions Accounting.
Having spent five years in New Zealand for her doctorate and two years in Denmark to learn the language, Gabby has returned to the UK ready to put her international insights to good use.
Alison Isherwood (MEng), Cambridge
Alison is determined to play her role in creating a more sustainable future, using her technical experience and analytical skillset alongside her more recently acquired sustainability insight.
She loves the concept of business with purpose, a key enabler of sustainability. This led her to join CausewayGT, a geothermal start-up focused on decarbonising industrial heat as well as working with sustain:able as an Associate, specializing in emission forecasting and accounting.
Alison has a MEng in Chemical Engineering and 24 years of experience working as a reservoir engineer and technical leader in oil and gas, both in the UK and overseas.
In 2020-2021 Alison completed a 9 month PGCert programme in Sustainable Business with the University of Cambridge, as well as her ISO-14064 GHG accounting & verification qualifications.
Alison is an enthusiastic mentor and volunteer, including chairing the London SPE Net Zero committee since 2020, which engages stakeholders across the energy industry and beyond on sustainability issues.
