Bioenergy
Why is it important?
Bioenergy is produced from organic material, known as biomass, which contains carbon absorbed by plants through photosynthesis. When this biomass is used to produce energy, the carbon is released during combustion and returns to the atmosphere. As more biomass is produced an equivalent amount of carbon is absorbed, making modern bioenergy a near zero-emission fuel. It is the largest source of renewable energy globally, accounting for 55% of renewable energy and over 6% of global energy supply.
What is the role in clean energy transitions?
Modern bioenergy is an important source of renewable energy - its contribution to final energy demand across all sectors is currently five times higher than wind and solar PV combined, even when the traditional use of biomass is excluded. Heating remains the largest use of bioenergy, and while space heating will be increasingly electrified, bioenergy could potentially play a major role in hard-to-electrify sectors such as aviation and shipping.
Where do we need to go?
Modern bioenergy does not include the traditional use of biomass in developing countries and emerging economies for cooking and heating with open fires or simple stoves, which badly impairs human health and the environment. Use of these traditional biomass falls to zero by 2030 in the Net Zero Scenario to achieve the UN Sustainable Development Goal 7 on Affordable and Clean Energy.
Tracking Bioenergy
Bioenergy is a source of energy from the organic material that makes up plants, known as biomass. Biomass contains carbon absorbed by plants through photosynthesis. When this biomass is used to produce energy, the carbon is released during combustion and simply returns to the atmosphere, making modern bioenergy a promising near zero-emission fuel.
Modern bioenergy is the largest source of renewable energy globally today, accounting for 55% of renewable energy and over 6% of global energy supply. The Net Zero Emissions by 2050 (NZE) Scenario sees a rapid increase in the use of bioenergy to displace fossil fuels by 2030. Use of modern bioenergy has increased on average by about 3% per year between 2010 and 2022 and is on an upward trend. More efforts are needed to accelerate modern bioenergy deployment to get on track with the NZE Scenario, which requires deployment to increase by 8% per year between 2022 and 2030, while simultaneously ensuring that bioenergy production does not incur negative social and environmental consequences.

Countries and regions making notable progress in advancing bioenergy include:
- In March 2023 the European Union reached a provisional agreement between the Council and Parliament on the update to the Renewable Energy Directive (RED III). The agreement includes strengthening sustainability criteria around the use of biomass for energy by applying the “cascading” principle while incorporating national priorities. The European Union also set a target in 2022 to achieve 35 bcm annual production of biomethane by 2030 (compared to 3.5 bcm today) and launched the Biomethane Industrial Partnership in September 2022 to help support this goal.
- The United States announced important new funding in 2022 under the Inflation Reduction Act that provides funding for several steps along the bioenergy value chain, including to scale up the use of sustainable biomass and waste resources in the United States to produce sustainable aviation fuels, chemicals and biomaterials including advanced fertlisers, and to spur innovation within these sectors, including in conversion technologies.
- India extended its Biomass Programme in 2022 to support domestic solid and gaseous biogas production and use to 2026.
- Australia decided in 2022 to exclude the burning of native forest wood for electricity generation from its renewable energy targets, reversing a decision made in 2015, and thus helping to ensure that bioenergy resources are sustainably sourced.
Bioenergy has a critical role to play in getting on track with the NZE Scenario
Bioenergy has a critical role to play in getting on track with the NZE Scenario
Bioenergy is an important pillar of decarbonisation in the energy transition as a near zero-emission fuel. Bioenergy is useful because there is flexibility in the contexts and sectors in which it can be used, from solid bioenergy and biogases combusted for power and heat in homes and industrial plants to liquid biofuels used in cars, ships and planes. Furthermore, it can often take advantage of existing infrastructure – for instance, biomethane can use existing natural gas pipelines and end-user equipment, while many drop-in liquid biofuels can use existing oil distribution networks and be used in vehicles with only minor alterations.
Bioenergy use needs to increase in a wide variety of applications by 2030 to get on track with the NZE Scenario, including the following:
- Biojet kerosene used in air travel increases from around zero in 2022 to account for 10% of all aviation fuel demand in 2030.
- Liquid biofuel consumption more than doubles from 2.2 million barrels of oil equivalent per day (mboe/d) (4.3 EJ) in 2022 to over 5 mboe/d (10 EJ) in 2030, mainly for road transport.
- Bioenergy use in industry increases substantially, from supplying a little over 11 EJ (7% of energy use) of energy in 2022 to more than 17 EJ (10%) in 2030, mostly in cement, pulp and paper, light industry and other industry.
- Biomethane used in the gas grid to heat buildings grows from very small quantities today to reach just under 1.5 EJ in 2030.
- Bioenergy used for electricity generation provides dispatchable, low-emission power to complement generation from variable renewables. Its use nearly doubles, from generating about 700 TWh of electricity (about 2.5% of total demand) in 2022 to around 1 300 TWh (about 3.5% of total demand) in 2030.
- Bioenergy with carbon capture and storage (BECCS) – which creates negative emissions by capturing and storing bioenergy emissions that are already carbon-neutral – also plays a critical role. BECCS captured and stored 1.5 Mt of CO2 in 2022 and increases to around 190 Mt of CO2 in 2030, offsetting emissions from sectors where abatement will be most difficult.
Bioenergy is one component of the overall increase in renewable energy in the NZE Scenario.
Aligning with the NZE Scenario will require not only an accelerated increase in modern bioenergy use, but also a phase-out of traditional use of biomass

Bioenergy use by sector globally in the Net Zero Scenario, 2010-2030
OpenTotal global bioenergy use in 2030 under the NZE Scenario is only about 12% higher than in 2022, although this by itself does not tell the full story. Over 35% of the bioenergy used in 2022 was from biomass for traditional cooking methods such as over open fires – practices that are unsustainable, inefficient, polluting and were linked to over 3 million premature deaths from indoor air pollution in 2021 alone. The use of traditional biomass falls to zero by 2030 in the NZE Scenario, in line with the UN Sustainable Development Goal 7 on Affordable and Clean Energy. Modern bioenergy usage, which excludes traditional uses of biomass, nearly doubles from about 41 EJ in 2022 (6.5% of total final consumption) to almost 75 EJ in 2030 (around 13% of total final consumption). This requires the average annual rate of growth to increase from 3% over 2010-22 to 8% over 2023-30.
The NZE Scenario sees the traditional use of biomass in rural areas partly replaced by biogas digesters, bioethanol and solid biomass used in modern cookstoves, providing a source of clean cooking for almost 1.2 billion people by 2030. Sustainable bioenergy also provides a valuable source of employment and income for rural communities, reduces undue burdens on women who are often tasked with fuel collection, brings health benefits from reduced air pollution and proper waste management, and reduces methane emissions from waste decomposition. More needs to be done to phase out the traditional use of biomass, as its use in absolute terms has stayed relatively constant since 2016.

Bioenergy supply globally in the Net Zero Scenario, 2010-2030
OpenBioenergy comes from a variety of different sources. Some bioenergy sources – such as black liquor from paper production – are the by-product of an industrial process that would have taken place anyway. More commonly, though, bioenergy is sourced from purpose-grown crops or trees in a highly land-intensive process relative to other forms of energy. Unsustainable bioenergy production can have social consequences – such as competition for land use and impacts on food prices – as well as negative environmental externalities, such as worsened biodiversity and net increases in emissions.
Aligning with the NZE Scenario will require bioenergy production to increase, but care must be taken to ensure that doing so does not result in significant negative effects for society or the environment. In accordance with these sustainability considerations, there is no expansion of cropland for bioenergy nor conversion of existing forested land into bioenergy crop production in the NZE Scenario. Under this scenario, in 2030 60% of bioenergy supply comes from waste and residues that do not require dedicated land use, compared to less than 50% today. Innovation and deployment in biofuel conversion technologies will be required to fully unlock the potential of wastes and residues.
Policy makers are increasingly putting in place schemes to support bioenergy use in their economies, although stronger efforts are needed to get on track with the NZE Scenario

Many jurisdictions are moving to introduce policies that suggest they see a significant long-term role for bioenergy in the energy transition. These include:
- More than 80 countries currently have policies supporting liquid biofuels.
- A number of countries, including Canada, China, Lithuania and the United States, have announced since 2021 that they are investing significantly in the research and deployment of biofuels.
- Additionally, the United States passed the Inflation Reduction Act in August 2022, which includes extended and new policy support for biofuels, biochemicals and biomaterials, particularly advanced biofuels and sustainable aviation fuels.
- India extended its Biomass Programme in 2022 to support solid and gaseous biogas production and use across India to 2026.
- Brazil launched measures to support sustainable biogas production in 2022.
- Canada implemented its Clean Fuel Regulations in July 2023 with support policies to expand feedstock supply.
- In 2022 Indonesia, Brazil and Argentina increased biofuel targets in the transportation sector.
While this progress is positive, bioenergy use has been expanded at a slower rate than is required in the NZE Scenario – expanded policy support is therefore needed.

Recommendations
-
It is critical that the increased bioenergy production needed to get on track with the NZE Scenario does not create negative impacts on biodiversity, freshwater systems, food availability or human quality of life. Only bioenergy that reduces lifecycle GHG emissions while avoiding unacceptable social, environmental and economic impacts should receive policy support. Sustainability frameworks can help to phase out the traditional use of biomass and help scale up a variety of sustainable feedstock supplies.
The European Union, the United States (through minimum GHG thresholds in the Renewable Fuel Standard Program and the incorporation of indirect land use change into California’s Low Carbon Fuel Standard) and Brazil have established frameworks to codify some aspects of liquid biofuel sustainability, but other countries must also ensure that rigorous sustainability governance is linked to bioenergy policy support.
In addition to this, monitoring, reporting and verification frameworks should be employed to address accounting issues related to the use of bioenergy in power generation, especially in relation to negative emissions accounting for BECCS.
-
National governments can employ a combination of regulatory measures such as mandates, low-carbon fuel standards and GHG intensity targets to incentivise modern bioenergy usage. These policies should be implemented within a larger framework for reducing emissions – such as emissions pricing – to ensure that policies provide the incentive to reduce emissions, not simply to increase bioenergy demand.
-
Bioenergy offers high flexibility in reducing emissions as it is able to replace fossil fuels in a variety of contexts. Nevertheless, sustainability constraints limit production to 100 EJ and nearly 20% of energy supply by 2050 in the NZE Scenario.
Bioenergy policy design should therefore target the highest-value uses for bioenergy in the energy sector, including its use in existing infrastructure, its potential to produce high energy density fuels for long-distance transport, its dispatchability to support the integration of variable renewables into the grid and its usefulness in meeting broader policy objectives, such as waste management and rural development. Power sector policies can design auctions suited to specific grid stability requirements and demand profiles (when power is needed at different times of the day and year), while fuel policies can incentivise use in hard-to-abate areas like aviation.
-
Policies incentivising greater use of waste and residues as fuels will be important to get bioenergy on track. Supporting waste- and residue-based energy use in Latin America, China and ASEAN countries would be particularly fruitful as these regions possess significant feedstock resources.
Relevant policies include de-risking measures such as loan guarantees on pre-commercial conversion technology and biofuel quotas for emerging fuels. The European Parliament, for example, adopted sustainable aviation fuel blending targets in July 2022 to support an expansion in use of waste- and residue-based fuels. Additionally, support is required for the demonstration and deployment of technologies that can convert waste and residues to finished fuels, particularly woody feedstocks.
In Europe, policies that discourage sending waste to landfills (such as landfill bans or taxation) have prompted higher energy-from-waste (EfW) development. Improving waste collection and sorting is also necessary to EfW capacity.
