The Centre for Sustainable Healthcare (CSH) is one of three groups funded by Pitch Pledge Party, a new experiment that connects practical carbon-cutting projects with committed donors. Find out more
The NHS is the largest organisation in Europe, with 1.3 million employees and yearly carbon emissions topping 22 million tonnes.
This presents some brilliant opportunities to save resources, and the Centre for Sustainable Healthcare's project aims to fix up Britain's energy-hungry kidney dialysis machines.
The idea is to help and encourage NHS organisations to fit a tried-and-tested device called a heat exchanger to 1,000 machines across the country, reducing their energy consumption by around 20% and saving nearly 300 tonnes of carbon each year.
Their Pitch Pledge Party funding is paying for a project coordinator to help the Centre's networks deliver and publicise the retrofits.

In a year of record-breaking extreme weather, it's never been clearer that we need to step things up in a big way.
But when it's time to do more, it's also worth reminding ourselves what we're capable of.
So to celebrate another remarkable year, we've put together a big roundup of the best things we did together in the last 12 months. As always, it makes for pretty inspiring reading!

Hard to believe it's been a year since our Pitch Pledge Party crowdfunding event, but the three carbon-cutting projects that pitched for money that night haven't wasted a moment.

Centre for Sustainable healthcare's energy-saving refit programme for dialysis machines was part-funded by 10:10ers as part of our Pitch Pledge Party project. Here's their nine-month update.

In 2010, renal technicians Fraser Campbell and Steve Milne found that adding heat exchangers to old Dialog+ dialysis machines could cut their carbon footprint by about 20%. Since then we've been working to promote this technique and help other renal units try it on their own machines.
Manufacturer BBraun has now started shipping all new machines with heat exchangers pre-installed, and has retrofitted the machines in their own dialysis units – a huge success for carbon reduction!
Where the magic happens
Back in October, the 10:10 community got together for the Pitch Pledge Party event and helped us kick off our work in kidney units where we retrofit heat exchangers on inefficient dialysis machines.
It's all pretty technical but each upgraded unit uses a hefty 20% less energy.
Since my last update in December, we've been working with Braun (the company that makes the machines we're upgrading) to track down and get in touch with everyone who owns, one of the inefficient old models. Braun itself also runs a number of units and we are following these up to ensure they're all fitted with the carbon-saving heat exchangers.
