The Carbon Neutral Challenge
The trend towards a hotter climate
The image below shows how the temperatures across England are already increasing year on year, setting a clear trend towards a hotter climate which will bring significant consequences.
Warming Stripes 1884 to 2018
The 'Warming Stripes' by Professor Ed Hawkins MBE show how global temperatures have increased between 1884 and 2018. The colour scale goes from 7.6°C (dark blue) to 10.8°C (dark red)
Imperial College London and the Grantham Institute have developed a set of Frequently Asked Questions which bring together expert knowledge on climate science, economics and politics, if you want to find out more about the climate crisis and possible solutions on a national and global scale.
Where Cornwall's carbon emissions come from
The diagram below shows where Cornwall's carbon emissions come from.
Our road transport and homes combined, make up 44% of total emissions and highlights how individual actions and choices have the potential to make a big impact.
We are committed to using our influence and working with others to enable more people to make positive changes to their lifestyle to drive carbon emissions down.

What is Carbon Neutral?
Becoming carbon neutral means taking out as much carbon dioxide from the atmosphere as we put into it.This is also known as 'Net Zero Carbon'.
Carbon Dioxide - Carbon Dioxide Absorption = 0
This can be achieved in two ways, by reducing the amount of carbon dioxide we are producing and by capturing the carbon dioxide we do produce so that it can't enter the atmosphere.
Becoming carbon neutral will bring us closer to a way of living which is based on balance and ensuring that our impact on the planet supports a positive future.
While some things about the way we live will change, we will always need a society which welcomes everyone and allows us all to thrive.
The 'Tipping Point'
A target of 2030, ahead of the UK Government's target of 2050, will give us our best chance of keeping global warming below 1.5°C.
This is the point at which the climate impacts we're already experiencing will go from bad to potentially catastrophic. We'll see natural systems cross danger points, triggering lasting changes and transforming life as we know it; extreme storms, heatwaves, mass loss of natural habitats and species.
Natural carbon absorption
Carbon can be absorbed through our use of land across Cornwall.
This can be from planting and maintaining, but also includes how our soil is looked after, and even seaweed farming.
The diagram below shows how carbon can be absorbed naturally.
This is why projects such as the Forest for Cornwall are so important, and also why it's important to look after the natural environment and ensure we don't use peat based fertilisers.
The carbon emissions and net zero gap
The picture belows shows a graph showing the scale of the challenge for Cornwall to get from 4 million tonnes of Co2 down to net zero.
The sharp trajectory needed to reach 2030 will require radical action, even 2050 will be challenging - but if we do nothing our carbon emissions will only continue to rise.
Currently we are absorbing 125 kilotonnes of carbon, meaning that there is a gap of 1,014 kilotonnes which we need to reduce by, if Cornwall is to become carbon neutral.
We can find ways to increase carbon absorption, for example through increasing the number of trees, hedges and wetlands, but there is no getting away from the fact that we need to drastically decrease our consumption and our emissions.
Text descriptions of the charts on this page.
Chart Description - The blue bars illustrate cooler temperatures going from dark blue to light blue through to pink and the hottest red temperature. The leftmost column of colour represents the year 1884, the furthest right represents 2018. There is a clear trend apparent. In earlier years the blue bars are the most common. As we look to the right, the red bars become the norm - not the exception.
Chart description - the bar chart shows different sectors in Cornwall and the percentage of carbon they emit. Commercial and industrial buildings emit 23%, on-road transport 22%, Homes 22%, Agriculture 18%, Waste 6%, Industrial Processes 6%, Aviation 1.5%, rail transport 0.75% and marine navigation 0.75%
Chart description - the vertical axis (Y) of the chart goes from zero to four million tonnes of Co2. The horizontal axis (X) shows the years 2020 to 2055 running left to right. There are three lines on the chart; two green and one black. The first green line shows a steep curve downwards from 4 million tonnes of Co2 in 2020 down to net zero in 2030 - which is our target. The second green lines show a less steep curve from four million tonnes of Co2 in 2020 down to net zero in 2050 which is the government's target. The black line which represents the 'do nothing' scenario, shows a gradual rise from 4 miilion tonnes of Co2 in 2020 to nearly 5 million tonnes of Co2 in 2055.
