Chris is a leading consultant in environmental and waste matters who managed the first successful defence to an Environment Agency Crown Court prosecution in 1998, as an abuse of the legal process. In 2007, he steered OSS Group Limited in its landmark Court of Appeal End of Waste ruling against the Environment Agency. In 2016, via a judicial review case brought by his company ProTreat Limited, he succeeded in changing the government’s legal position in England & Wales to bring Small Waste Oil Burners within the remit of the Industrial Emissions Directive.
