We all have a duty of care to be environmentally responsible and look after the world we live in Given the nature of our business, Cook Arboricultural Services employ the following environmental practices to reduce our impact on the environment. We use biodegradable chain oil which ranges between 93 – 97% biodegradable. All our vehicles are compliant within the limits set by the London Low Emission zone (LEZ). All of our waste is 100% recyclable. We plan our work to enable us to run our machines more efficiently and for shorter periods of time to reduce emissions and noise pollution.
