These are emissions from our buildings and production sites. 2020 was the first year we measured performance against our science-based targets, and we are well on way to achieving a 59% reduction by 2030. As part of our Net Zero roadmap we have identified 21 projects in which we are investing significantly over the next 8 years to progressively reduce emissions across our UK and Irish sites.
From 2016, reduce Scope 1 and 2 absolute emissions by 59% by 2030 and to Net Zero by 2040
Since 2020, we have procured 100% renewable electricity to power our sites, reducing about 53% of our baseline operational emissions to zero. At present, we purchase certified Renewable Energy from our providers. With the demand for renewable electricity increasing rapidly, we are exploring options to secure future supplies by investing in renewable energy generation. For example, we are progressing a planning application for a 2MW wind turbine and completing feasibility studies on installing PV panels on a number of our sites or adjacent land for producing renewable energy.
F-gases which are used in refrigeration systems are very potent Greenhouse Gases and account for about 18% of our baseline emissions. We have progressively reduced fugitive emissions from our sites over the last 5 years, and we target to replace these systems with net zero emission, ammonia refrigeration systems by 2030.
Burning fossil fuels to heat water on our sites accounted for approximately 26% of our baseline operational emissions. Over the last few years, we have been switching to lower emission fuels such as Liquefied Petroleum Gas (LPG). We will reduce these emissions rapidly by 2035, through a range of measures, including using renewable electrical heat sources and updating equipment to burn lower emission and carbon neutral fuels such as BioLPG. We will install renewable sources of heat recovery such as air to water heat pumps, beginning with our Llanybydder site in Wales in 2022.
Fuelling our own vehicles accounted for about 2% of our baseline emissions, and we plan to switch 100% of the company fleet to electric vehicles by 2030.
