Marshalls Carbon Calculator

Marshalls is committed to achieving the highest standards of environmental performance, preventing pollution and minimising the impact of its operations. The Marshalls' Carbon Calculator enables you to enter the details of your hard landscaping, by product and quantity; it then displays how many tonnes of embodied CO2 this equates to. The Carbon Calculator measures CO2e (carbon dioxide equivalent) encapsulating all greenhouse gases that contribute to global warming and calculated using Life Cycle Assessment methodology from raw material original to delivery of product(s) on site.

Total: kg CO2 as an example to offset this amount of carbon would require  tree

Calculations are based on 1 average sized tree with a lifespan of 99 years being equivalent to 0.73 tons CO2 and rounded up to the nearest tree.

Offsetting: Marshalls is reviewing its carbon offsetting recommendations in line with DEFRA’s Consultation on establishing a voluntary Code of Best Practice for the provision of carbon offsetting to UK customers.

In the mean time, you can find out more about carbon offsetting at:

Climate Care

Climate Care supports DEFRA’s active involvement in the voluntary carbon market. If DEFRA provides government endorsement only for compliance based offsets, Climate Care will offer such offsets to customers alongside existing voluntary emission reductions.

Carbon Neutral Company

The CarbonNeutral Company offers offset projects that use both certified emission reductions (CERs) and verified emission reductions (VERs).

CO2Balance

Uses Voluntary Carbon Offsets. All its projects are fully additional, transparent and verified.

The Carbon Trust

The Carbon Trust can help organisations to navigate the offset market and advises to consider the purchase of only high quality offsets from verified projects that create truly additional emissions reductions.
