Internal flights between the Orkney Islands are to become greener. A recently launched eighteen-month project will test various low carbon emission aircraft on short routes between the islands. The aircraft power sources will include hydrogen fuel cells, batteries, and sustainable aviation fuels. The project will also assess the feasibility of using drones for delivering medical supplies.

Scotland is making substantial inroads in decarbonisation and tackling climate change. The country aims to reduce greenhouse gasses emissions to net-zero by 2045 and reduce them by 15% by 2030. Already 90% of Scotland's electricity supply is from renewables, and, encouraged by current progress, the Scottish Government is now focusing on reducing emissions from heating buildings and is heavily targeting new buildings.

Lendlease Europe has recently set out a bold plan to achieve zero carbon emissions from the fuel we burn by 2025 and absolute zero-carbon without using offsets by 2040. Here we will look at how the company intends to achieve these targets and examine some of their key milestones. 

Replacing natural gas by hydrogen for heating domestic residential and commercial buildings would have a massive impact on greenhouse gas emissions and reducing global warming. There is, of course, the important caveat that the hydrogen manufacture must be powered by renewable resources. There is no fundamental reason why this cannot be achieved, but there are significant challenges in doing so. 

If we could replace our standard central heating systems with a carbon-free solution, we would have the potential to reduce UK greenhouse gas emissions by as much as a third. Source: OFGEM. This would go a long way towards meeting the UK and Scottish governments net-zero targets. One solution is to replace natural gas-fired boilers with hydrogen fired boilers and produce the hydrogen using renewable resources. 

"When a weather-controlling satellite system suddenly breaks down, a scientist must race against the clock to prevent a climate cataclysm on Earth." Geostorm - Currently on Netflix

You may be confused but this is not a film review! During the recent lockdown some may have watched the film Geostorm on Netflix. Essentially the film is an action and adventure sci-fi fantasy film loosely based on geoengineering. The idea being that if the climate of the planet gets out of control we can fix it through large scale intervention of the earths climate system by using satellites. It got me interested in the science behind geoengineering and large scale climate intervention and whether this might be an easier option than reducing CO2 emissions the energy efficiency route.

The skies are bluer, there are virtually no con-trails creating cloud cover, and the air smells so much cleaner. It's just like the olden days that our grandparents would wax nostalgically about. Doubtless, the shutdown has improved air quality in our cities, and the effect is global. But is it just a blip or will it have a long term impact on health and climate change?
