Meet BigGreenAcademy

BigGreenAcademy offers courses which train, equip and teach ‘Everyday Champions’ the easy ways to cut costs and better champion energy & sustainability as part of what they do every day at work, regardless of whether it’s their specific job or not.

This includes our flagship industry accredited ESTA ‘Energy Sustainability Champions Course’ as well as our ‘Energy Sustainability Coaching’ and ‘Energy Sustainability Mastery’ courses. Courses can be taken in person (bespoke in groups of 8-12) or online.

Those not ready for a course, includes lots of free resources for anyone looking to improve energy and sustainability performance at their workplace in the simplest way.

What's the Big Green Solution?

Come inside the Big Green Room to find out more. 

What are you waiting for?

Pressures to cut costs and reduce our environmental impacts have never been so immense; with more electrification of heating and transport systems, for example, energy prices are likely to increase significantly unless we massively bring down our existing energy consumption.

The Climate Action Tracker tracks the climate change action of different country contributions against the globally agreed Paris Agreement:  "We all need to do much more."

For the Net Zero 'Win for All', we need to live up to a number of unchanging fundamental qualities in everything we do.  In general terms, we have structured these as the '5-Rs' - to Review, Reduce, Reuse, Recycle and Rethink.

This is about doing the right thing, taking responsibility and all of us continually exploring more ways to make improvements to make every consuming process better - guided our practical courses and forums.

BigGreenAcademy brings together different professions, from different organizations and from around the world so we can all work more closely together and make a bigger difference, a place where we learn from each other.

Global net human-caused emissions of carbon dioxide (CO2) needs to fall by about 45 percent from 2010 levels by 2030, en route to reaching ‘Net Zero’ around 2050.  (IPCC)
We all need to make big cuts in emissions by 2030

Our Story - How the Big Green Concept was Born

Output from our first ever Big Green Event, 2008.  

The “Big Green” concept was born out of success of working with different teams across a UK airport from 2007 to 2010.

Our aim was to bring together different teams and business partners to collaborate more locally within their respective communities within the airport.

Initially there was no capital money available for investing in energy and environmental improvement projects so we had the opportunity to try out lots of different people-based solutions and ideas.

After three years working across the whole airport, we massively surprised ourselves with the teams delivering an average of 15% savings across all buildings and infrastructure; the best areas were saving more than 30%.

The focus was initially on energy as this is where the biggest business benefits often are.  Over the four years, we also targeted water, waste streams and renewable energy investments, all in context of better sustainability.

Regular workshops and events helped turn discovery into success.  Directors reinforced key priorities, celebrated industry awards and were confident in letting everyday champions lead it all up locally for themselves.

Success is very much down to the everyday champions involved.

We've been privileged to have continued to work with the airport applying the same techniques to other applications such as development projects, retail and commercial business partners over the last decade.  See our Case-study '10+ years of energy management through people'.

What’s Happened Since?

Since 2010, led by the Discovery Mill, we have been working with a select band of different client organizations to support, and help energize, step change in their energy and sustainability performance using simple hands-on solutions.

Over the last decade or so, we have run Big Green events, developed Big Green apps, led training programs and helped a wide variety of different organizations develop their strategies for their energy & sustainability improvement.

We have worked with schools, hospitals, airports, universities, government estates, facilities management service partners, development design teams, commercial businesses, retail, tourism businesses, medical specialists, manufacturing and logistics organizations, and many others; with operations and estates reaching across the world.  

We have found whatever the sector, and country, generally the same fundamental principles apply. 

In 2021, with the Covid-19 epidemic, we took the opportunity to take stock. Going forward we all need to be able to work better virtually and in person, while bringing benefits to ourselves as well as our organizations.

BigGreenAcademy was born to help extend the reach and diversity of the people involved.  This will enable us all to share more of our experiences and ideas, make use of online courses and make a bigger difference by learning from each other.
