Easyjet continues to make progress towards its zero carbon planes due in the sky 2030

One of the most complex issues to address in decarbonization is that of air travel. It is all very well for people to suggest that simply nobody should travel. This is not a long-term solution, not least because the vast majority of conservation relies on tourism to raise the funds for it to take place.

Long-haul flight is a problem to be fixed in the future, however easyjet is working on finding a solution to short haul flight of up to 500km.

Wright electric, the company which is developing the planes has announced that it has created an electric propulsion motor at 2MW. The aim would be to use 10 of these motors – which would add up to a similar amount of power as the aircraft the fly today. 2MW for an hour at full capacity would be 20MWH

Whether Wright electric has identified batteries that can supply enough power to run these motors for long is not yet known.

The Democratic republic of Congo has had a moratorium on logging since 2002, the current minister of environment has suggested ending this

Deforestation is rarely good for local communities. Having lived on the land often for hundreds or thousands of years, the deforested land is usually sold off. Furthermore it can no longer be used as a resource for food gathering – and often without the forest the rains are less reliable so local farm crops fail.

Containing enough carbon to cause serious problems worldwide, the Congo rainforest also houses 3 of our closest relatives

It is thought that as much as 70 million hectares could be lost if this goes through. This is 270,000 square miles an area the size of Morocco lost.

Even with the moratorium in place three logging leases have been given to Chinese companies.

What makes this threat even greater, is that some of this area that would be deforested lies in the peatland areas, which could mean the end of the peatlands and the release of billions of tonnes of carbon (these peatlands are thought to contain 30 billion tonnes of carbon

Tiger doubling from 2010 aim review – Sumatra

Indonesia is a archipelago of islands. Once connected to the Asian mainland, animals were able to make their way along the peninsular. When sea levels rose in the ancient past they were marooned on the islands.

Once they were found on a few islands including Bali and Java. They are now only found Sumatra. Sumatra is thought to have 400 tigers in 2010. This is down from as many as 1000 back in 1978.

San diago zoo estimate the number remaining in the wild at 400-600, but I cannot find any reason for this higher band.

It is possible that the tiger population has increased a bit, but in certainly has not doubled.

2 and a half billion trees died after the El Nino of 2015-6 in the Amazon

El Nino are natural weather phenonium generally occurring between every 2 and 7 years. It would appear that as predicted, the El Nino is getting worse as a result of climate change.

This mass die off released carbon dioxide greater than the annual emissions of a country like the UK or Australia.

The fear is that this will become a common event as the planet warms.

The problem is that with this much carbon released, the Amazon as a whole was flipped from being a net absorber toa net emitter of carbon.

Tiger doubling from 2010 aim review – Thiland

As with many of the other countries on this list, precise population numbers do not seem to be available. What is clear is that in 2010 the tiger population was thought to be in excess of 100. Their current population is around 177 ( the population grew by 50% over the last 2 years).

Rapid growth of the population appears to be possible thanks to an improvement in their habitats health.

Coal power stations could cut coal use, and therefore emissions by 50%

Coal power plants have to be a thing of the past as soon as possible. This is because no matter how efficient they are, they are powered by digging up carbon and releasing it into the air.

However for the time being, there are many coal power stations across the world. Vishwanath Haily Dalvi of the institute of Chemical technology in Mumbai India has been looking at how we could assist this process with the suns energy.

By collecting the suns heat energy, and using this to heat the water, the amount of coal needed is reduced by 50%.

This could therefore be a more economic way of reducing emissions from power generation. Given that coal power emits 0.85 pounds of carbon per kwh (about 380g), cutting this in half would make carbon far cleaner. While this may well be expensive to set up, it might allow coal power plants to operate for a few years longer and therefore be worthwhile, as well as offsetting some of the damage from the large number of coal powered stations being built across countries such as India and China.

Tree planting is another potential problem of Brexit

George Eustice (secretary for environment among other things) announced in may, that the government planned to greatly increase tree planting in the UK. Indeed, his plan was to treble the amount of woodland to be created each year, to 30,000 hectares (which is 74,100 acres or around 120 square miles).

However, this constitutes around 90 million trees (each and every year). The problem is that tree nurseries in the UK, do not regularly have this level of demand – and it is not easy to scale up these tree growing for just a few years. In the past, we imported a great deal of the tree saplings to plant, however the Brexit deal we did makes this hard. Not only is it more expensive, but also there are strict import rules to protect from various tree illnesses. While this is important for the wellbeing of British woodland (it is foolish to try to offset climate change by planting trees, if these trees cause the death of many thousands already growing here.

Labour is also short, with 70,000 requested in recent years, but the government only giving enough visas for 30,000 seasonal workers.

This is an issue we need to solve. British woodland cover is well below that of most European countries, but more to the point it makes a significant part of our plans to reduce our carbon emissions over the next few decades.

Tiger doubling from 2010 aim review – Bhutan

Bhutan is a mountainous country, thought to have a small population of tigers. Tigers have been photographed thousands of meters up mountains, and is the only country where this is known to happen. In 2014 a census counted 103 tigers, up from the previous estimate of 75.

There appear to be no further census done. It is entirely possible that Bhutans tiger population has increased, but we cannot know.

Montpelier a city in France realized its error, and dropped an order for 51 hydrogen buses for electric instead

Montpelier had set aside $33 million for this project, over 2 years. This decision was made, after local officials realized that electric buses would be 6 times cheaper to run. This price included the building of a plant to make the hydrogen.

In terms of cost, it was estimated that the buses (for which the council was given help buying but not for running costs) would cost 3 million euros to run, yet only 500,000 for electric. The per mile price was 0.15 euro instead of 0.95.

Although they were going to be helped in purchasing, the hydrogen buses are also between 150000-200000 euros more to buy in the first place.

The myriad reasons that hydrogen is not a good idea have been obvious for some time. Green hydrogen (much of hydrogen is taken out of gas- obviously a nonstarter if your aim is reducing carbon emissions) requires a great deal of electricity to split water, and it would be far more efficient to just put that electricity in batteries and use them. Another issue is the compression of the gas. The only possible place where hydrogen might be useful is in aeroplanes.
