Capital Allowance on sustainable products

Dear All,

Can someone tell me if it is possible to attain a capital allowance or a taxation advantage from revenue on a product (Capital Purchase) which has the ability to reduce energy consumption (ESB)? Does this product have to be assured by Sustainability Ireland in order to achieve the tax advantage?

This any good to you?
