Welcome to our latest SnippETS newsletter.
This week we look at some strategies against climate change including closing the ozone hole, injecting sulphate particles into the atmosphere to block the sun and using hydrogen as a fuel.
We then look at some innovative building ideas, and finish with articles on “shared” bikes and edible bale wrap.
The Montreal Protocol, a 30 year old international treaty designed to protect the ozone layer, is considered by many to be one of the most successful multilateral environmental agreements (MEAs) in history. A recent assessment, released earlier this month, finds that the Kigali Amendment to this, if fully implemented, can avoid up to 0.4°C of global warming this century and help keep the global temperature rise to below the 2°C required limit.

New research suggests that putting sulphate particles into the stratosphere will reduce global temperature increase. Cooling the Earth by injecting sun-blocking particles into the stratosphere could be “remarkably inexpensive”, according to the most detailed engineering analysis to date. The researchers still suggest that emission cuts, adaptation and carbon removal should be at the forefront of climate action, but this solution could be our saving grace if warming gets out of hand.

Or could Hydrogen be the thing that stops the world overheating? We now explore what is happening in this space in NZ and around the world.
Firstly, The UK have been advised they will need hydrogen power in their mix to achieve their 2050 emission targets, but this will not be easy or cheap ,as replacing gas with Hydrogen will involve changing all the equipment or appliances used. Hydrogen as a fuel is mostly currently produced using a process involving gas too, so more renewable
