Our sustainability approach

The impact of bioenergy on social and environmental issues varies depending on local conditions and the design and implementation of a particular project. A specific feedstock is not necessarily always sustainable, or unsustainable. This is important for us to realize as sustainable biomass feedstock is the key to produce and supply sustainable aviation fuel (SAF). The challenge is to carefully take into account all legitimate claims on resource usage (e.g. energy, land, water, raw materials) and to deal with them in the right way. But what is right? Biomass for fuel use will always displace some other use. We believe that this should only be admissible if ‘higher value applications’ (e.g. living, food production, high conservation areas, leisure) are not displaced, if the side effects are far less negative than the usage of fossil fuel and if food security and biodiversity are not sacrificed.

However, for SkyNRG, sustainability is about much more than avoiding harmful impact. We believe that sustainability is all about improving the status quo and realizing the positive socio-economic impact. Well-managed projects, where SAF is produced in adherence to rigorous sustainability standards, can have a profoundly positive effect on the region, including: enhanced biodiversity, soil carbon increases and improved soil productivity, significant CO2 emission reductions (up to 80%), less dependency on fossil energy sources, reduced erosion, stimulation of local employment, and strengthening of local, regional and national economies.

Because we want to guarantee and control sustainability throughout the entire life cycle of biomass production, fuel refining and use, we have established various measures and partnerships. By joining forces in the supply chain and involving all relevant stakeholders, SkyNRG understands and acts upon the potential environmental and socioeconomic consequences associated with the development of SAF.

Measures and partnerships to guarantee the sustainability of our fuels

Independent Sustainability Board

SkyNRG installed an Independent Sustainability Board consisting of leading NGO’s and scientists, advising on all feedstock decisions, communication strategy, policy implications and growth strategies. Members of SkyNRG’s sustainability board are the WWF International, European Climate Foundation, Solidaridad Network, and the University of Groningen. For more info about the process and the people please visit the page on SkyNRG’s Sustainability Board.

Roundtable on Sustainable Biomaterials

To ensure market compliance and to be able to show quantitative and qualitative proof of sustainability, SkyNRG has its entire supply chain certified by the Roundtable on Sustainable Biomaterials (RSB). The RSB is a worldwide, multi-stakeholder initiative that brings together farmers, corporations, NGOs, experts, governments, and inter-governmental agencies concerned with ensuring the sustainability of biomass and biomaterial production and processing. RSB’s certification system is based on sustainability standards, encompassing environmental, social and economic principles and criteria. The RSB is widely accepted as the “gold standard” for voluntary certification approaches. RSB enjoys wide acceptance among industry and NGOs, and its comprehensiveness and objectivity have made it the most important voluntary framework for sustainable aviation fuels.

NGO network

Sustainability is always evolving, and different feedstocks and regions bring different sustainability issues. To make sure we’re not missing important information once we become active in a particular region or with a specific feedstock, we keep track of the latest developments and thinking through our global NGO network.


All feedstocks we have used for our Sustainable Aviation Fuel have been given a positive advice by our Independent Sustainability Board, after thorough analyses and discussion. There are no exceptions to this. Where possible, we use RSB certified feedstocks (and fuels). Currently, all our fuel comes from locally sourced Used Cooking Oil. Going forward, we will continue to keep a strong focus on true waste and residue streams. In assessing the sustainability of these feedstocks we not only take all direct impacts into consideration but also assess (potential) indirect effects (e.g. ILUC, indirect displacement).

To avoid confusion:

  • We have not touched (and will never touch for that matter) crude palm oil
  • Also, we do not regard PFAD and POME true waste and residues (as defined under the sustainability criteria of the Renewable Energy Directive)
  • Furthermore, we believe the legislation governing the sustainability of biofuels under the Renewable Energy Directive is weak, and we think the “EU RED compliance” argument for using feedstock like PFAD and POME is not a justification
  • The sustainability of feedstock and products depends on the actual impacts (direct and indirect) of a specific supply chain, and we therefore believe that we have the obligation to take additional steps (over EU RED compliance) to safeguard the sustainability of our products and operations
  • We believe in full transparency on everything we do

Share your information with us

Since we operate in a highly dynamic industry, we are constantly engaging with all relevant stakeholders to ensure the sustainability of our fuel. Despite the reports, data, case studies and other sources that we consult, we realize that our information can never be complete. Therefore, we are open to all information that will give us a better understanding of the sustainability impacts (positive and negative) of our fuel. If you have any information that you feel can strengthen our current options, help us to make better assessments in the future or perhaps even reconsider some of the choices we’ve already made, than please contact us on sustainability@skynrg.com.
