 Previous collaborations with Natural England on their district licensing for the Great Crested Newt  proved that there was an appetite and ability for the construction industry to support conservation while improving the planning process.The HBA therefore became involved on writing guidance and setting metrics for biodiversity net gain, which leaves the environment in a better state than when development began.As the only building trade association who rejected exemptions for small sites, the HBA is certain that the policy can be a springboard to both protect the environment and establish a new conservation and biodiversity industry.
