Grayce's answer:

Char.gy is a company which provides a convenient way for drivers to charge an electric vehicle on their street. They develop existing street structure to provide electric vehicle charging points.

Bang on. Really good answer.

Grayce's answer:

Very Light Rail (VLR) is a planned light rail tram system to operate in Coventry and it aims to operate by 2024.

Fact Checker:

According to Colin Knight at the Transport Delivery Committee meeting (4th November 2019, item #41) - Grayce is exactly right. In part of the footage edited out of the video above Darren and Elspeth also discussed the dates for the first routes for VLR being 2024/2025.

Grayce's answer:

Lead poisoning causes central nervous system damage and impairs neurological development in children.

Fact Checker:

Grayce is 3/3 - this is correct, unfortunately. From lead paint on cribs to anti-knock agents in fuel, lead is really bad for people. Example sources: a comment in The Lancet, an article in the New England Journal of Medicine (paywall), BBC news article.

Jessica's answer:

People can try and use less paper and use reusable bottles and retainers. People can recycle things and be mindful of what they put in the bin. Reuse plastic bags or buy non-plastic bags. People can fix or borrow things if broken instead of buying a new item. There are plenty of other things people can do as well.

Fact Checker:

Good answer! The key to making materials more sustainable is to reduce, reuse and recycle. Jessica has mentioned each one of those three. Reduce the number of bottles we use by filling yours up again and again. Reuse your plastic bags. Recycle materials that can't be used for anything else. There is even the fourth 'R' in there - repair! Being able to repair items instead of having to get a new one is very good for the environment.

Jessica's answer:

Denmark is by far the country helping the environment the most. Their levels of fine particle air pollution is 56.9% they have ambitious goals such as having half of their energy come from renewables by 2030. Also by 2050 to be independent of fossil fuels.

Denmark certainly are doing a lot to help the environment and in the scores of how well countries are performing to meet the target of keeping global warming below 1.5 °C Denmark is usually up towards the top. There are a lot of different ways to gauge how 'green' a country is, which makes it difficult to give a definite answer to this question.

Is it the country with the lowest carbon emissions per person? Unfortunately that might just show you countries that are less developed - fewer people owning cars or having central heating for example.

Is it the country with the biggest reduction in their greenhouse gas emissions in the last decade? That might not be fair on countries that are recently developing but are investing in green energy - those countries may not have had high emissions in the first place to reduce.

Is it the country with the highest share of energy produced from renewable sources? Or the country planting the most trees? It gets complicated fast! There are a few organisations that are trying to track the actions of various countries and I've linked a few below.

Aishah's answer:

Stay away from any means of transport that causes air pollution, get a car that is a hybrid or fully electric. If your vehicle is petrol or diesel set yourself a maximum mileage to ensure that you are not driving a lot because the less you drive, the less you contribute to global warming.

Fact Checker:

Electrification will play a huge role in reducing the carbon emissions from the transport sector so Aishah has picked a key topic to meeting the net zero emissions by 2050 goals. We also need to produce more energy in renewable ways that don't emit carbon.

Raisha's answer:

From a BBC news article: UK petrol and diesel cars will be banned in 2035. As a result people will only be able to buy electric or hybrid cars which will help move towards zero-carbon target by 2050.

Fact Checker:

Absolutely right - legislation has been brought in to reduce the sales of internal combustion engine vehicles and encourage producers to make, and consumers to buy, electric vehicles.
