By 2025, all new and replacement heating and hot water . As fossils, they are quite common, and probably more useful as indicators of the palaeo-environment, than as age indicators. Canada itself has also committed to reaching net-zero emissions by 2050. Few definitions of index fossils are mentioned below: "It is a fossil usually with a narrow time range and wide spatial distribution that is used in the identification of related geologic formations." Comments on this story are moderated according to our Submission Guidelines. How do scientists determine the absolute or 'chronometric' date of fossils?

A 2021 report from the Canadian Institutefor Climate Choices on different ways to get Canada to net zero said its modelling consistently shows "electrification of heating as a necessary part of the transition to net zero in Canada's building sector.". If we talk about macrofossils, they have the advantage over the microfossils because they are easy to see and find in the field but actually, they are rare whereas the microfossils are used by mineral resources industries after extraction of required information from these fossils.
