Through the Climate Change Act, the UK government has committed to reduce emissions by at least 80% of 1990 levels by 2050, thereby contributing to global emission reductions and helping limit global temperature rise to as little as possible above 2°C.
UK emissions were 42% below 1990 levels in 2016. The first carbon budget (2008 to 2012) was met and the UK is currently on track to outperform on the second (2013 to 2017) and third (2018 to 2022). However, it is not on track to meet the fourth (2023 to 2027).
To meet future carbon budgets and the 80% target for 2050, the UK will need to reduce emissions by at least 3% a year, from now on. This will require the government to apply more challenging measures. The majority of Britain’s greenhouse gas emissions now come from transport. So it is in this context that I want to investigate how London is reducing transport greenhouse gas emissions.
The annual road transport emissions for the Greater London Area (GLA) are projected to be 5,728,930t CO2 in 2030, (London Atmospheric Emissions Inventory 201330 data). According to Donnachadh McCarthy (Eco-auditor) that is about 1.4% of all UK current emissions . However in 2030 it would represent a far higher percentage of the total UK emissions, as other sectors are cut. Road transport in Greater London is seriously inhibiting our ability to reduce UK greenhouse emissions
When deciding whether an infrastructure project or transport policy contributes to or mitigates against global warming, we must compare the amount of energy consumed in producing it (embedded carbon), to the amount of energy used by the vehicles and infrastructure (carbon footprint) For instance, a carbon footprint can be used to express the carbon of running a car, embodied carbon would tell you the carbon footprint of producing a car
Whilst greenhouse emissions are not the whole story, nevertheless it is important to have calculations available to make informed decisions.
