Alternative fuels have been identified as an important tool to reduce the climate change impact of the aviation industry, but there are many challenges associated with increasing the production and use of these fuels in a sustainable way. In this series of reports for the Aviation Environment Federation we discuss issues relating to the lifecycle […]
Clean fuel standards (CFSs) and low-carbon fuel standards (LCFSs) are regulations which oblige fuel suppliers to meet a gradually tightening target for the average emissions intensity of their fuels. CFSs already exist (or are under consideration) in several USA states and in Canada. Cerulogy has developed a model for the USA’s road transport sector covering […]
BIKE is a multi-year project funded by the EU’s Horizon 2020 programme. Its aim is to assess the market potential of the EU’s low ILUC-risk concept – from practical, regulatory, and economic standpoints. The BIKE consortium includes expertise from academia, industry, international agencies, and the private sector. Cerulogy has a leadership role in BIKE’s policy-oriented […]
This study for the European Federation for Transport and the Environment (T&E) reviews the use of rendered animal fats by the EU biofuel industry, the impacts of this use on other animal fat consumers and the potential for this diversion of resources to cause indirect emissions. As featured on BBC news! You can read a […]
In 2023, the International Council on Clean Transportation (ICCT) released its first annual Global Automaker Rating, assessing the readiness of car manufacturers for the transition to electric vehicles. Dr Sandford and Dr Malins supported the development of the rating by reviewing ICCT’s methodology and data collection.
The “low indirect land use change risk” (“low ILUC-risk”) concept was developed to assess whether a given batch of crop-based biofuels competes with other land uses and is likely to stimulate the expansion of agricultural land. At the core of low ILUC-risk is an “additionality principle” that aims to ensure that special policy treatment is […]
Cerulogy supported the Changing Markets Foundation with the analysis of methane emissions presented in their Emissions Impossible report, highlighting the climate change impact of companies in the meat and dairy industry.
This report for the Danish Energy Agency presents an overview and review of indirect land use change modelling, and provides a discussion of options for Denmark to adjust its biofuel policy to take further account of indirect land use change emissions.
In this report for Transport and Environment we review the efficiency benefits of electric drive vehicles against combustion engines, and discuss how this efficiency differential could be appropriately reflected in revisions to the Renewable Energy Directive.
This report for the Spanish NGO Ecologistas en Acción considers the potential for the development of an aviation biofuel industry in Spain. It notes that it may be challenging to reorient existing renewable diesel capacity to aviation fuel production because of the need to find non-food feedstocks if the fuel is to be counted under […]
