UN1TY, a Guernsey business that specialises in strategic advisory, has launched ESG Calc, an award-winning  portfolio analytics platform designed to help investors, financial institutions, and governments by giving them insight on environmental risks associated with their property portfolios.

Traditionally, assessing a portfolio's sustainability and climate risk is a laborious and time-consuming process, often hindered by fragmented data and a lack of readily accessible insights. This has lead to missed opportunities, increased risk exposure, and difficulty in achieving sustainability goals.

By efficiently quantifying both physical (such as flood and fire) and regulatory climate risks, (such as properties with low-rated EPC certificates no longer being lettable in future) ESG Calc gives the insights necessary to minimise those risks, and pivot to opportunity, easily and cost-effectively.  A centralised, user-friendly dashboard highlights portfolio-wide energy ratings, flood risk assessments, carbon emissions, and compliance readiness, automatically verified, updated and in one place.

The platform enables potentially stranded assets to be identified while uncovering long-term asset value, driving strategic decisions around future investment, renovations, and divestments.

Armed with these insights, organisations can future proof their portfolios by proactively complying with environmental regulations, avoiding costly surprises, and ensuring long-term sustainability.

ESG Calc’s innovative approach was recently recognised when the firm received the 2023 Innovation in Technology Award at the Veyaon Awards, highlighting UN1TY's commitment to developing solutions that address critical business challenges.

Mike Ozanne, Founding Partner of UN1TY says, “ESG Calc empowers clients to unlock the full potential of their portfolios by providing critical insights into their environmental and social impact, alongside financial risk management. This comprehensive approach empowers strategic decision-making and a future-proofed investment strategy."

“You can’t manage what you don’t measure” adds Rollo de Sausmarez, Partner at UN1TY. “Those with property portfolios or property backed loan books have unquantified climate risk that ESG Calc can assess.”

Guernsey advisory business, UN1TY have trained 100 students on the internationally recognised Carbon Literacy course since they started the course last year. UN1TY's training program, accredited by the Carbon Literacy Project, equips participants with the knowledge and skills to understand the basics of climate change science, identify how their actions contribute to greenhouse gas emissions, explore practical strategies to reduce their carbon footprint, and become empowered to advocate for positive change within their communities and workplaces.  

Over 40 local organisations have participated in the training, which UN1TY designed the specifically for Guernsey, combining local climate change expertise with actionable steps to address the island's unique challenges. Participants learn how their and their businesses everyday choices impact the environment and gained practical tools to make a difference. 

At the same time, UN1TY has also been awarded the status of a Bronze Carbon Literate Organisation. This award recognises UN1TY’s commitment to educating the community, educating their own employees, and inspiring change.  

Expanding on the in-person course for Guernsey, UN1TY have also created an online-hybrid version of the Guernsey course, as well as a Jersey course, of which the first cohort is happening in June.  

‘The course was a first-class introduction to the concepts of climate change, sustainability and net-zero. The information was presented in a really easy to understand way, we enjoyed the interactive exercises and learning how we can all take steps to reduce our impact on the environment. This training can benefit any individual or business, and could be the key to unlocking collective action to help protect our world for future generations.’ 

Nichole Culverwell, Agency Director, Black Vanilla, and Carbon Literacy Student
