Fruit and vegetables have an exceptionally low carbon footprint compared to other food categories. Nonetheless, we are constantly striving to reduce our greenhouse gas emissions along the value chain. Our ambitions in this domain are invigorated as we witness the consequences of climate change first-handed, with more frequent droughts and extreme weather events affecting growers all over the world.
We measure our corporate carbon footprintannually by calculating our total Scope 1, Scope 2 and Scope 3 emissions. Our footprintin terms of Scope 1 and 2 emissions covers our own operations (consisting of factories operatedby Greenyard but excluding co-packers), our own warehousing (consisting of distribution centres operated by Greenyard but excluding third-party warehousing) and our own logistics(consisting of fleets operated by Greenyard and including our company cars). Scope 3 emissions cover the fruit and vegetables we are sourcing, third party logistics, packaging, waste, and business flights. The data is calculated and reported in line with the GHG-Protocol. The insights are used to set annual reduction targets and identify key initiatives to achieve them.
Greenyard has committed to reduce its Scope 1 and 2 greenhouse gas emissions by 50% by the end of 2025 compared to 2019. This year, our total greenhouse gas emissions remained stable (-0,23%) despite the exceptional sales growth (+10%) and the energy-intensive Frozen and Prepared divisions being confronted with stockpiling of frozen and canned products during subsequent lockdowns. In addition, energy use is the prime source of greenhouse gas emissions in our operations. The energy intensity for processed products decreased by 2% due to efficiencies in production. For better transparency, we have been disclosing our climate-related risks and impact under the terms of the CDP (climate change) since 2020. We were pleased to achieve a B- score in our first year of participation.
We are committed to set carbon reduction targets in line with limiting the global temperature increase to 1.5°C. Next to our initial reduction target of 50% by 2025, we plan a 70% reduction target by 2030 on our way to become carbon neutral by 2050. In terms of our Scope 3 emissions, we will continue to stimulate our supplier base to adopt science-based targets. We aim to submit our proposals to the Science Based Targets initiative (SBTi) in the fall of 2021. In line with our plans to implement the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), we will also conduct a climate-related scenario analysis to further refine our strategy.
We will continue our efforts to decrease our emissions in line with our current commitments, plan to firmly increase our renewable energy use and actively invest in alternative energy sources such as solar panels and biomass production. This year, 10% of our electricity consumption came from renewable sources.
