Sometimes it’s useful to take a step back and look at the bigger picture in order to fully appreciate the scale of what it means to get to net zero CO2 emissions. We are constantly being told that we must all do our bit towards this great goal in order to save the planet. To find all the big statistics on this, one place to look is <a href=Global Energy Review: CO2 Emissions in 2021 – Analysis – IEA>here</a> on the International Energy Agency (IEA) website. This organisation is, of course, committed to phasing out fossil fuels, even though it was founded to ensure security of oil supplies to member nations in times of crisis.

Here is an interesting statistic for 2020:

306.32 Mt of CO2 was produced by the UK  for energy. The whole world produced 40 Gt of CO2. So using those figures we can calculate the % of world energy related emissions from the UK. (Energy includes that used for electricity, heating, transport, industry.)

306.32×10^6×100 divided by 40x 10^9 = 0.77% 

So we can see that our emissions have fallen well below the 1% of world emissions which is often quoted. However 306.32 Mt is still a very large amount, when you consider that all the simple ways of reducing it have already been implemented. 

An example of a scheme to reduce emissions is the new waste strategy being proposed by the New Forest District Council. The proposed changes are calculated to save 1037 tonnes of CO2 per annum, which to many people would sound impressive. But, set against the UK annual emissions, it can be calculated as:

1037×100 divided by 306320000%, which is  0.0003%

This puts the true scale of the reductions required to reach zero. Of course net zero means that some emissions will still be allowed, but these figures do not even include emissions due to agriculture
