Carbon credits

Hi everyone,

Welcome back to Green World! Today we're talking about an industry that has expanded massively in the past few years. Carbon credits are one of the measures that companies are taking to reduce CO2 emissions.

But how does it actually work? The companies that sell carbon credits fund projects to protect an area of forest or rainforest from deforestation. They then calculate how much carbon dioxide emissions they have saves by protecting this area. This means they can now sell 'negative carbon emissions' to companies. In this way, the companies are funding the protection of said area and are causing negative emissions while doing so meaning that the company can still emit greenhouse gases but can claim to be net zero. One carbon credit is basically the permission to emit one ton of CO2. This is good for the company as well as they are able to advertise as sustainable at a relatively low cost to actually reducing their emissions. And it means that the rainforests like the Amazon are protected. This industry expanded greatly during the COVID-19 pandemic: in 2021 150 million credits were sold at a total cost of 1.3 billion dollars.

This all sounds good. Maybe too good? In reality, there are problems. Probably the biggest problem is calculation errors. If a project overestimates how much carbon it is saving, intentionally or not, then they can sell more credits. Not only is this a money-making machine, it also means that companies are falsely under the impression that they are allowed to emit more. Overestimations of up to 400% so 4x the actual amount of carbon have been found in studies and investigations. These credits are called "phantom credits" because they don't actually exist. Another problem, that is very similar, is companies 'protecting' an area that isn't actually at risk in the first place. The idea of credits is to save rainforests from deforestation, but if these rainforests aren't actually at risk then it's kind of useless. Sellers can make millions because they don't even have to do any protecting. Tying into this is the fact that there is no reliable way of knowing if a credit is legit or just a scam. A study looking into a selection of projects determined that over 60 million credits didn't actually have any positive effect on the environment. One of the world's biggest sellers had 94% of their credits determined useless. These sellers are obviously denying all claims by scientists and journalists. There have even been allegations of the mistreatment of native people by the projects active in their areas. One final fundamental problem is that companies now have an excuse not to reduce emissions by buying credits.

We hope you found this post interesting. Vote here to decide on next year's monthly post. See you next week!

April Top Tips: ten tips for environmentally friendly travel

Hi Everyone! We haven't been very present on the blog again recently but we are back today with ten top tips for environmentally friendly travel. Most forms of travel over long distances (unless you are willing to put in a lot of physical effort) use fossil fuels and are generally not good for our planet. So today we will be giving you a few tips which although won't mean that your travel is 100% planet friendly, will be a good start to doing as much as you can. Your Green World Blog Team💚 1. Use trains and boats rather than planes where possible Planes are awful for the environment. They are, however, extremely practical and so easy to use, cheap...It's hard to avoid them! They are so quick too so you don't have to spend as much time travelling. However, they are really bad for the environment. For example, you could fly once to Edinburgh from Heathrow for the same carbon dioxide levels as driving to Edinburgh 336 times! 2. Fly...

El Niño & La Niña - what are they and what effects do they have?

Hello everyone, You've probably heard of El Niño and La Niña before. Especially El Niño has been discussed a lot recently in the media. El Niño and La Niña are part of a climate pattern found in the Pacific Ocean that occurs roughly every two to seven years. However there is no real regularity or predictability further into the future. They affect global weather patterns and economies. So first of all, let's cover what is actually happening here. In normal circumstances trade winds blow across the Pacific from South America to Asia. This pushes warm water from South America to Asia meaning that the ocean is a lot cooler off the west coast of the Americas compared to the east coast of Asia. The cold water off the coast of the Americas comes from the ocean's depths and is filled with nutrients. During El Niño those driving trade winds become weaker or even stop entirely. Scientists haven't work...

Maldives - the direct impacts of climate change

Welcome back, Today we’re looking at the direct impacts of the climate crisis . The main reason why people don’t believe in climate change is that they can’t see it with their own eyes. So, we’re going to have a look at the Maldives where the effects of climate change become more obvious with every passing year. Maldives The full name of the Maldives is The Republic of the Maldives. It is an independent country made up of about 1 200 islands in the North Indian Ocean. The northernmost island is situated 370 miles away from the mainland (India). The islands are actually the tips of an ancient volcanic mountain range that is now almost completely submerged. In fact, the highest point is 1.8m-2.4m above sea level with the average elevation being 1m above sea level. The islands have a large tourism industry, due to the stunning nature found on and around the islands. 500 000 - 1 500 000 tourists visit the islands each year. This is mainly 'nature to...

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back ...

Marine heatwaves - an ever growing threat?

Hi everyone, So today we're talking about marine heatwaves. We all know about normal heatwaves, they come almost every summer and are either a blessing or a curse depending on where you live. But today we're talking about marine heatwaves. They are increasing rapidly and have become a commonly mentioned topic. There are multiple definitions of marine heatwaves. Generally, they are considered a period of time with unusually high temperatures. Exactly how high and for how long changes depending on which definition you choose. The most common one definition is when the temperature is over the 90th percentile of the area's average seasonal temperature for at least 5 days in a row. For anyone who doesn't know what a percentile is, if you take a test and are at the 90th percentile then it means you are better than 90% of the people who took that test. So in our context, the temperature has to be higher than 90% of the seasonal temperatu...

The limits of the Earth - the planetary boundary model

Hi everyone, So today we're talking about a model that was introduced in 2009 and has offered a new perspective to thinking about environmental issues. The planetary boundary model has 9 boundaries, each has a safe zone. Once the safe zone is exceeded, the stable conditions on our planet are considered at risk, and there can be severe and possibly irreversible changes. The nine boundaries are considered separate however, they greatly affect each other. Novel Entities describes the introduction and accumulation of man-made novel chemical compounds. These include pesticides, nuclear waste and microplastics. Stratospheric Ozone Depletion refers to the depletion of the ozone layer which was a major problem in the 90s. Atmospheric Aerosol Loading is air particle pollution. Ocean Acidification is self-explanatory. The boundary Biochemical Flows is composed of two separate boundaries; nitrogen and phosphorus. Both of the ele...

Veganism or vegetarianism - are they really sustainable?

Hello everyone Does veganism come with health issues? Is it sustainable? And does vegetarianism change anything? - We're going to be comparing three different diet types: veganism, vegetarianism, and a mixed diet, in multiple categories. This post is structured into the following sections: human rights health area needed animal rights greenhouse gas emissions Which diet is the best? Image and text sources Warning: There are no graphic images in this post. However, in the 'human rights' and 'animal rights' sections, there are descriptions of physical and mental abuse towards both humans and animals. Skip those sections, if you know you can't deal with that. Human rights This may seem like an unrelated topic at first, but in many industries, the rights of people in poorer countries are abused because it's cheaper for the compa...

19.07.2020: Animal of the week: Honey Bees

Hi everyone, This week's animal is the honey bee. Enjoy! General Information An average honeybee hive is made up of one queen, hundreds of male drones and thousands of female workers. If the queen bee dies then a new queen is created. The workers select a young larva and feed it with a special food called ‘royal jelly’. The ‘royal jelly’ makes the larva grow into a fertile queen. Queens live for several years but the workers only live for five or six weeks. An average worker will make a twelfth of a tee spoon of honey during her entire life. Drones are turned out of the hive and left to die in Autumn. In the summer months, the queen bee is very busy, she can lay up to 2500 eggs in a single day. How they affect the world around them Honey bees are very important for flowers, fruit and vegetables. This comes from the fact that they are pollinators. They help the plants by transferring pollen between male and female parts, meaning the plants can g...

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...
