Study assessing the achievements of the Heritage Action Zone (HAZ) programme in England. Through the HAZ programme, Historic England works with local people and partners, including local authorities, to help breathe new life into specific places that are rich in heritage. The study assesses the achievements of the programme to date, identifying benefits, risks, issues and lessons that could be applied for future rounds.

Japanese knotweed (Reynoutria japonica) is recognised as one of the most pernicious invasive weeds in Europe and worldwide. The UK has legislation surrounding Japanese knotweed; however, the impacts for property sales mainly stem from lenders classing properties with Japanese knotweed 7m or closer as being ‘at risk’, as per the existing RICS framework. Furthermore, there are indications that the general public perceives Japanese knotweed to be a greater risk to property than some evidence suggests, with potential impacts for property valuations and sales. Other countries may have less stringent legislation and guidance than the UK regarding Japanese knotweed. Whilst it is treated as an invasive weed, the majority of removal projects aim to reduce the environmental impacts. The Parliamentary Science and Technology Committee held a one-off oral evidence session in early 2019 to explore the science behind the effects of Japanese knotweed on the built environment. The report produced following the session included several recommendations, one of which was a desk-based research study to review international approaches to Japanese knotweed in the context of property sales.

RPA and RPA Europe have been commissioned by the European Environment Agency (EEA) to map the current and future regulatory status of the 19 HBM4EU Priority Substance Groups and to produce policy briefs detailing the progress made so far under the HBM4EU project by reviewing available human biomonitoring evidence, the ability of HBM4EU to produce new human biomonitoring evidence and how this data can be fed into chemicals policy and risk management.

Study assessing the the activities, operations and actions of Inshore Fisheries and Conservation Authorities (IFCAs) and future management and structure of these. The outputs of the study are intended to feed into the drawing up of bylaws, successful management and knowledge sharing partnerships.

RPA, in association with Royal HaskoningDHV, undertook an evaluation of the Partnership Funding policy for flood and coastal erosion risk management for Defra and the Environment Agency.

Hydrofluorocarbons (HFC's), used as refrigerants and in other applications, are potent greenhouse gases with a global warming potential (GWP up to 1000 times greater than carbon dioxide). Hydrofluoroolefins (HFO's) are an alternative to HFC's and have zero ozone depleting potential and a low GWP. The study will look at HFO's and their degradation products, summarise chemical processes related to atmospheric fate, assess degradation products most likely to be formed as well as impurities that can contribute to pollutant emissions.
