asked Her Majesty's Government:
What plans they have to ensure that any private sector corporate research into average emissions effects from vehicles, including aircraft and heavy goods vehicles, are made available to Government and scientific research bodies.
Decisions regarding what private sector research is conducted and how this research is used and disseminated are clearly a matter for the private sector itself.
The Government publish their own research, enabling the private sector to consider how their own work links in. The Government also welcome submission of private sector research data so that this may be considered in developing policy. Where private sector organisations approach the Government with new technology or ideas impacting on emissions of air pollutants or greenhouse gases, we encourage them to commission independent research to demonstrate the impacts and make this publicly available.
