Climate Change – the facts

Climate Change – the facts

Regular readers will remember the piece we ran in the May edition of Mature Times on climate change after the protests by the environmental group, Extinction Rebellion. Following on from that article, I thought it important to delve deeper into the factors contributing to climate change, and greenhouse gas emissions, and reveal some of the facts and figures that readers may not be familiar with.

As I reported in the last issue the UK is doing sterling work in reducing its greenhouse gas emissions year on year in line with its legal commitment that it has made. This commitment is an 80% reduction in carbon emissions from the 1990 baseline figure by the year 2050. As part of this commitment, the Government has pledged to phase out electricity generated by coal power completely by 2025. Progress here continues to be very encouraging and it is highly likely that this target will be achieved.

Record breaker

The UK continues to break records for the length of time it has gone without coal generated power this year. For example, there was a bit of a landmark in the first week of May when for the first time since the industrial revolution the UK went seven days straight without any power from coal generation entering the National Grid.

However, that record wasn’t destined to last for long because, as I write this towards the end of May, the UK has gone almost 11 consecutive days without the need for coal power generation, and with the weather set fair this may go for even longer. What’s more, as a result of the good weather the National Grid has reported that power generated from natural gas is also considerably down on the levels usually seen. The good news is that as reliance on coal fades, and the growth of renewable energies reduces the need for gas power generation, this sector saw its emission levels fall some 7% during 2018 as the drive toward low-carbon technology increases. Great news indeed.

Figures for the same period also saw that emissions from transport had encouragingly started to fall, something they have hardly done since the 1990 base year. You probably won’t be surprised to know that transport is now the largest contributor to greenhouse gas emissions in the UK and so any reductions are clearly good news. This shows progress in the right way. The fact that the figure is only a 3% reduction should not be derided, and whilst it is clear that there is still much more that can be done, any reductions should be seen as a positive.

The UK calculates emissions by monitoring the individual contributing sectors, of which there are nine. These are energy supply; business; transport; public sector; residential; agriculture; industrial process; land use; land use change and forestry; and finally waste management. The 2018 provisional figures show progress in reducing emissions across all sectors except the public sector and residential ones.

Meanwhile, in terms of the sources of power generation, the level of power generated from renewable sources continues to rise and reached an all-time high of 33% last year. Add this into the power generated from nuclear, which is also considered low carbon, then some 53% of our energy was generated from low carbon sources last year – yet again a record.

So is this enough?

Whilst good progress is being made, the question is “Is This Enough” to enable the UK to meet its greenhouse gas emissions targets by 2050. Well, most analysts think that the answer to this question is no, and that more needs to be done. This is because, whilst encouraging progress has been made to date, further progress towards the target becomes harder – in other words, the easy gains have been made and to achieve the ambitious targets difficult decisions will need to be made and implemented. Now, none of us has a crystal ball, and this may well be scaremongering, but the only way we will ever know the answer to that question is through continued progress as it is made overtime.Industry pollution - Free for commercial use No attribution required - Credit Pixabay

Meanwhile, climate change is having a bigger and bigger impact on the planet as each year goes by – the statistics prove that – and as the world continues to modernise and its population continues to grow, then more needs to be done to protect it – I don’t think many people would argue with that as a statement.

What can we do about it?

However, we must recognise that we all want to continue to live our lives as best we can. We all want the freedom to travel and to consume what we want and with small changes, we can still live our lives to the full but also make a difference. If you think that the simple act of switching off a light, for example, doesn’t really contribute all that much, then think again: If a million people switched off a light just think of the effect that will have on power consumption.

Small changes to our lifestyle can have a major impact. If we think about the food that we consume, here are some things that we can do to reduce the impact we have on our planet:

  • Reduce your own food waste – reducing food waste means that you buy less and therefore less has to be produced – all of which saves on the energy required to produce the food and on the transport required to get it to the shops.
  • Support local producers – yes it might be a few pence dearer but it helps to sustain the local economy and reduces the “food miles” the food has to travel to reach the point of sale.
  • Think about the amount of meat you consume – now I’m not advocating that we all go vegan or vegetarian, that’s an individual’s choice, but reducing meat consumption can help. Reducing the number of animals being reared for food, reduces greenhouse gases – animals are massive producers of methane. Good progress is being made here in the UK with consumption of beef, lamb and pork said to be down by over 4% in 2018 alone.

The biggest UK contributor to greenhouse gas emissions is travel and we can all make small changes that can make big impacts. Here are some of the things that you can do to help:

  • The simple and easy one is walk or cycle – especially if your journey is a short one. This will bring other health related benefits as well.
  • If you drive, make sure that when stuck in traffic, or parked up by the side of the road, that your engine is not idling, and that you have turned it off. I’m sure many of us get frustrated at the number of drivers who don’t do this.
  • Make sure that the tyres on your vehicle are at the correct pressure as this is more fuel efficient. Also, look at ways of improving your driving efficiency; for example take 5 or 10 mph off your motorway speed – you won’t get there much later – and slow down a bit earlier as you approach traffic lights.
  • If you are going to the same group or function, try car sharing, you might drive a few miles extra to collect a friend but it will keep their car off the road. If you are travelling longer distances consider whether public transport is a viable alternative.

The above are just a few of the ideas or suggestions of how we can all help in two areas of life. What is certain is that help we must. It’s no good ignoring the facts because climate change is not going away. We can all try to make sure that our legacy is that we tried to do all we could to reduce our impact on the planet as much as we possibly can.
