Inspiring Bristol green tech innovators

Green Tech South West Introducing Bristol green tech innovators as part of Bristol Tech Festival 2021

Event overview

Green Tech South West are delighted to showcase a set of lightning talks from three fantastic Bristol Green Tech innovators, as part of the Bristol Technology Festival 2021.

“Seeing the wood for the trees with corporate activism”

Jaya Chakrabarti MBE, Chief Evangalising Officer at Project Vana

Jaya Chakrabarti MBE, founder of Project Vana for Green Tech South West and Bristol Tech Festival 2021 on how to achieve world-aforrestation

With recent press coverage on afforestation being a way to “fix the planet”, there is dire need for decent LIVE data on land ownership to identify where trees can be planted. There is also a complexity when it comes to the most effective land use once that land has been identified.

Corporate land ownership data is a missing piece of this puzzle. It is our intention to fill in some blanks using available corporate transparency data and technologies. This talk is about what we’re doing right now and how we’ll achieve world-afforestation.

“The cooling crisis: How global cooling is contributing to global warming”

Molly Allington, CEO of Albotherm's talk for Green Tech South West and Bristol Tech Festival 2021 on how global cooling is contributing to global warming

Molly Allington, CEO at Albotherm

Air conditioning alone accounts for 20% of electricity usage from buildings and 10% of total global electricity usage. To stop this cycle in its tracks, we need to make better use of our natural resources and find more sustainable alternatives to air conditioning.

Molly will take about how she develops paints that are designed to reflect the sun’s rays at high temperatures, reducing solar gain and helping to cool buildings without burning fossil fuels.

She’ll also explain what the cooling crisis really means for our future on this planet and how we can go about mitigating its effects.
