GreenTech South West 2020

Building A World-Class Community Tackling Climate Change with Technology.

As another year kicks into gear, we at GreenTech South West (GTSW), have been looking back at our first year’s impact. Despite the difficulties of 2020, we are still amazed, uplifted and ever hopeful by the incredible people and initiatives working to tackle climate change.

We feel more sure than ever that the South West of England is ideally positioned to play a leading role in the global effort to reverse the climate change catastrophe. We’ve put together a summary of the incredible work we showcased at our 9 free speaker-led events of 2020, and we think you’ll also share our optimistic view!

The 2020 GTSW community

We have over 600 members at the time of typing and we’re proud to lead an inclusive, diverse and welcoming community.

If haven’t joined us yet, you are welcome to do so for free, at:

You can follow us on LinkedIn (here) and Twitter (here) and #GreenTechSW. Or if you want to get in touch directly our email address is

Over three-quarters of our members are based in the South West of England, but we do welcome people from anywhere to join in. We have good representation from across the UK, including London, and excitingly a growing international member base from European countries (Holland, Germany, Sweden and Denmark) as well as the US.

Our core aim is to put three main topics in the spotlight through a mixture of talks, Q&A and tech demonstrations:

  1. How digital technology can help preserve our environment and tackle climate change.
  2. The environmental impact of digital technology itself and how to mitigate it.
  3. Actions we can take as individuals and businesses to harness technologies in a sustainable way.

Mitigating our own emissions

We are mindful of the carbon emissions we create as a result of our physical and online events, and of our online presence itself.

Whilst our overall emissions aren’t especially significant, we estimated that our online Aug event with Asim created approx 10kg of carbon emissions. We still want to ensure we offset any negative environmental impact our activities are responsible for.

South West based offsetting company Ecologi provide the perfect solution. We now have our own forest at to which both founders and members donate trees. We planted a whopping 1,005 trees in 2020 which has helped offset just under 21 tonnes of CO2, far more than our estimated annual emissions.

We couldn’t be more grateful to all the kind people for their tree donations and for helping us create a net positive impact.

Our sponsors and supporters

GreenTech South West is sponsored by ADLIB Recruitment and supported by Future Economy Network and Climate Action Tech.

Our founding story

We held our first event on 27th Feb 2020. The story of how GTSW began is one we love to tell. It was serendipity and a shared passion for sustainable technology solutions and a rapid response to climate change that brought us, your three Co-Founders, Ellen, Hannah and Mike together at the beginning of 2020.

Mike and Ellen, who work together at ADLIB Recruitment, were driven to find a way to highlight how those in the South West were using tech to tackle the ever-deepening climate crisis.

Hannah, a freelance WordPress developer, had been running the Bristol WordPress people meetup and wanted to channel her energy into increasing climate change awareness in the tech industry.

At the end of 2019, both groups independently began work to make their ideas a reality, and weirdly both settled on running a first event in the week commencing 24th Feb! Mike and Ellen pipped Hannah to the post, and scheduled their first meetup just days before Hannah was about to publish hers. Hannah saw the event and reached out to have a chat with Mike and Ellen.

The trio agreed that creating competing communities didn’t make sense, especially given the urgency of climate change, and instead agreed to become a team and work together. The rest, as they say, is history.

And wow, are we glad we did find each other! With no idea of what 2020 was about to throw our way, we found ourselves able to lean on one another in difficult times and still grow the GTSW community.
