The term "offsetting system" is correct and can be used in written English.
Offsetting systems are used to balance out the negative impacts of human activities on the environment. For example, a company might purchase carbon credits to offset their emissions from manufacturing.
The proposals are not based on sufficient evidence, which have been properly tested and evaluated, to set up a reliable biodiversity offsetting system.
A mandatory, rather than voluntary, offsetting system would encourage a market to develop, which would in turn allow more environmentally and economically viable offset projects to be brought forward.
Any offsetting system must emphasise the continuing primacy of the 'mitigation hierarchy', where offsetting is only considered after alternative development sites or a means of mitigating the environmental loss in situ have been exhausted.
If a system is introduced too rapidly, and without adequate testing and evidence, the prospect of a workable and supportable biodiversity offsetting system would be undermined for many years to come".
"There is a danger that an overly simplistic offsetting system would not protect these long-established ecosystems," she added.
Nonetheless, we estimate that ICAO's offsetting system may cost airlines about $23 billion USD from 2021 to 2035, or equivalent to 3% of annual global revenue and two thirds more than IATA's net profit in 2014, a good year.
It is impossible to reduce biodiversity into a system of credits as envisaged by many offsetting systems.
The United Nations hopes eventually to apply the offset system to all meetings, "as well as individual travel," he said.
Two members of the European Parliament have demanded an inquiry by the European Commission into the "gross misuse of European consumers' money" in the UN-administered offset system.
A Heathrow spokesperson said: "Heathrow supports the international aviation industry's commitment to carbon-neutral growth from 2020 and the UN's international civil aviation organisation, which plans to introduce a mandatory carbon offset system to achieve this goal".
As a typical case, the mid-chord offset system (MCO-system) is selected in this paper to study the error propagation of chord-based systems.
