Does anyone know, approximately, how much CO2 is emitted to generate 1kWh of electricity in the UK? I know it's a tough one because of all the renewables that are in play and the grid is still propped up by gas. 

Then, does anyone know how much CO2 is emitted by a an oil boiler for 1 litre of fuel?

0.245 kg of CO2 per kWh or 2.5kg per litre burned.

@editor There is always a problem with averages, which is also reflected in the data above. 
Average UK CO2 emissions is 10.0 tonnes per person per year (ref https://www.carbonindependent.org/23.html)

With EVs, an ASHP, green electric, recycling and composting as much as possible (including soft plastics), eating less meat (3 vegetarian meals/week), not flying anywhere for 2years I think our carbon footprint is down to about 4.5 tonnes CO2 per person per year. Which is good on the one hand. 

But the target is 2 tonnes CO2 per person per year by 2030 to meet Paris and COP26 objectives to keep global warming below 1.5C 😳. Wow. 

So I / we have much to do. I think my numbers are still above target because of the things I buy. Our purchases need to be made in a carbon neutral way. We need to personally burn less stuff. The UK government needs to continue to decarbonise the energy market. I need to invest in Ripple energy. 

I’d welcome a discussion on this very complex but critical topic.

Mr. Abramovich is going to struggle to get in under the two tonne mark.
