Natural Capital and Biodiversity: A Briefing Note for Policy-Makers (July 2019)


This briefing note outlines what natural capital is, benefits of the approach, some concerns with the approach, and actions to take to maximise natural capital.

This briefing was drafted by the CIEEM England Policy Group.

Biosecurity Toolkit For Landscape Consultants

The Landscape Institute has published a new plant health and biosecurity toolkit to help built environment professionals combat Britain’s biggest pests and diseases. 

Biosecurity is emerging as major threat to ecosystem resilience, with new regulations and guidance being developed in response to pests, pathogens and the changing climate. This toolkit has been developed in partnership with the Society of Garden Designers (SGD), the British Association of Landscape Industries (BALI) and the Association of Professional Landscapers (APL) and represents a significant development in cross-industry coordination.

 The purpose of the toolkit is to identify best practice across the sector, and embed agreed systematic biosecurity protocols into every stage of a landscape project in a way that has never before been achieved.


You can find out more about the toolkit and access the resource via the Landscape Institute's website



Biodiversity Net Gain- Principles and Guidance for UK Construction and Developments



Biodiversity Net Gain is an approach to development that leaves biodiversity in a better state than before. Where a development has an impact on biodiversity it encourages developers to provide an increase in appropriate natural habitat and ecological features over and above that being affected. In such a way it is hoped that the current loss of biodiversity through development will be halted and ecological networks can be restored.

Defra has recently consulted on making biodiversity net gain a mandatory element of the English planning system, however many developers are already designing net gain into their development projects and national planning policy frameworks already encourage the net gain approach. Quite simply, a policy of no net loss has not worked and we need to do something different if we are to make any progress towards reaching our biodiversity targets.

Biodiversity net gain still relies on the application of the mitigation hierarchy to avoid, mitigate or compensate for biodiversity losses. It is additional to these approaches, not instead of them. Put simply, it involves the use of a metric as a proxy for recognising the negative impacts on habitats arising from a development and calculating how much new or restored habitat, and of what types is required to deliver sufficient net gain.

CIEEM, IEMA and CIRIA have been at the forefront of exploring the potential for a biodiversity net gain approach. In December 2016 they published the first UK Principles on delivering biodiversity net gain through development following extensive consultation with stakeholders. In February 2019 they published new guidance on delivering net gain. Development of this practical guidance, together with a series of case studies at a range of scales, were funded by a number of industry sponsors and written by an expert author team.

Energy and Resource Efficiency Good Practice Guide


The Institution of Chemical Engineers (IChemE) Energy Centre has launched a good practice guide to help organisations become more resource efficient and reduce waste.

The Energy and Resource Efficiency Good Practice Guide was launched at the Energy Centre's annual meeting on Tuesday 15 January, and gives practical advice on how to reduce waste, improve resource efficiency and help achieve international climate change targets in a cost-effective way.

The guide was authored and edited by a group of chemical engineers, working as part of an Energy and Resource Efficiency Task Group, led by Vice Chair of the Energy Centre, Mark Apsey.

More information on the Energy Centre can be found on the IChemE website
