Pangolins are returning to Kenya

Long thought to be extinct in the country, one was caught, back in 2018. As a result, effort is being put into protecting this species. Farmland around the Serengeti erected electric fences in order to stop elephants from stealing their crops, however, unfortunately, they have been having an unintended consequence.

Pangolins need to be able to roam large distances, and they have been regularly being electrocuted. Unfortunately, they roll up in a ball, as a natural reaction to threat, and this has lead to many rolling up around the wire, thereby being electrocuted.

This discovery in 2018 was of a dead pangolin, and as a result, many farmers have changed how their electric fence works to help protect this creature.

There are only thought to be 30-80 pangolins left in the country, but by making these small changes, the few pangolins that remain will be able to thrive, and the population is likely to grow.

This is a pangolin sighting that was filmed on the Massai mara

“EU must cut carbon emissions 3 times faster to meet targets”

A new report has calculated that the EU is only cutting carbon emissions at 1/3 of the rate which is required in order to meet the 55% cut – from buildings, transport and agriculture by 2030

While emissions are falling, they are not falling anywhere near fast enough

Over the last 30 years, carbon emissions have dropped by 32% . while this is an impressive amount, it is far short of the promise.

The best predictions for the future, are that by 2050 the EU will have cut emissions by around 43%. While this is an important step, it is far short of what has been promised.

More importantly, at the current rate, we will have only met a further 1/3 by 2050.

The job is not done – much of the carbon emissions from the last 3 decades have been easy to achieve. They have been achieved through efficiency gains, and moving production offshore. Very little change in the EU behaviour has been required.  

An easy gain, both for individual cost, and emissions is electric cars. A faster transition is likely to save countries much money too (though it is true that at the current time, there is an issue with the tax revenue coming from fossil fuel sales.

It is far cheaper to run clean alternatives, so we must make that show in the figures.

Some governments are making efforts to help, but not in every way. For instance, in the UK, you can get money towards an electric car, but not a used one (which given the reduction in price, is likely to go further and help more. On heat pump the government is doing better – with the increase in the air-source heat pump grant, the cost to individuals has reduced to around 3500 (on average buying a heat-pump as well as installing and changing radiators to work with the lower temperature (bigger) the cost is around £11,000. However, many people have missed the advertising, and are unaware. It is true that new build homes will not be allowed to install boilers after 2025. 

However, older houses with gas boilers will be unaffected by the change until 2035. But the average cost for a new boiler, plus installation is thought to be around £4000, in 2023, meaning that for many homes, it will be cheaper to replace now.

Furthermore, while an air-source heat pump is thought to be around £50 more to run each year, should something like a thermal solar panel be added, the cost is far lower.

With carefully designed rules for builders, the switch to low cost private transport, and low cost private house heating can be cheap and obvious. At the current rate, though, this is not being met.

In the UK, clearly better understanding and education is essential, and builders need to see that adding things like thermal solar panels is a must.

Will it happen? will the EU meet our 55% target? at current speed, it is clear that this will be hard work. However, if this money is not found, we are likely to need far more in the future to adapt to the world we are creating.

Is the COP conferences a waste of time, if climate change deniers are able to lead it?

At the current time, countries in the region in which the COP is held will chose a president. In theory, that is fine, however, in practice if this is going to continue then the middle east should be banned from hosting the conference.

So, what precisely did Sultan Al Jaber say, which was so troubling?

Firstly, he claimed that a ‘phase-out of fossil fuels would not allow sustainable development “unless you want to take the world back into caves'”.

He then claimed that there is ‘no science’ to suggest phasing out fossil fuels is the only way to achieve 1.5C.

After being laughed at, over this utterly insane statment, he suggested that the comment had been misinterpreted. It should be noted, that this was in response to a question from a woman, which he was relatively rude about.

Do you think this woman misunderstood?

He even had the gall to suggest that the misrepresentation was undermining his desire to reduce carbon emissions (perhaps if this is true, it can start with his huge fossil fuel company can show this?). More than 100 countries are already supportive of this.

The worlds uptake of electric cars must accelerate. This is partly underway – last year around 67 million cars were sold, but 14% of these were electric, up from just 9% the previous year. The uptake is accelerating.

It should also be noted that apart from extreme heat in the UAE, continued global warming will also damage the UAE in extreme ways. The UAE economy is 0.5% of the global economy, in the end, places like this may refuse to accept the end of oil, and will have to be bankrupted, as cars move to 100% and many other industries clean up their act.

We have bought a used electric car: does it make financial sense? Why should you consider doing the same.

So we have recently bought an electric car!

This is what a tesla looks like

For any regular readers, you would have seen my article from a few days ago. When people are writing articles comparing the emissions from generating electricity to the tailpipe emissions of the combustion engine – any one with a brain is asking why? Given you are not comparing like for like. We estimate that our carbon emissions reductions from replacing our car may reach 10 tonnes a year. Each fill up of our petrol car meant about 40kg of petrol, which took 110kg of emissions to dig it out of the ground and transport it (often around the world).

So from an environmental position, yes it certainly makes sense.

But what about from a financial position?

Fossil fuel cars make ‘hundreds of times’ more waste than electric cars – according to a Guardian article, despite what most media tries to claim

This should not be news to people, but because of the rubbish that is spread by many with vested interests in the current situation, it needs to be dealt with again.

So the argument is that because electric cars battery does not last forever, but every part of the combustion engine car does, the electric car is going to make more waste.

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.

How can an average UK household reduce their carbon footprint?

The average UK household has a footprint of around 20 tonnes. Now it is true, that this is well below USA emissions as that is for 4 people – so average emissions of around 5 tonnes per head.

However, with relatively small adjustments, this can be cut dramatically. 12.3% of emissions come from heating, and a further 10.4% comes from electricity.

Furthermore, a significant cut can be made through replacing beef mince with Turkey mince. This can reduce your food carbon footprint by as much as 50%, and given that most mince is eaten in dishes with other foods, it is often unnoticeable
