Reducing reliance on fossil fuels, by increased adoption of renewables, has become a worldwide priority to mitigate climate change and minimize greenhouse gas emissions. In Canada, the use of geothermal heating (or ground source heat pumps) has become a popular option for heating and cooling buildings and it is anticipated that, in the near term, most large buildings will include geothermal heating as part of their climate control strategy. However, very little is known about the environmental impacts of geothermal heating on the subsurface environment. Furthermore, few regulations exist for geothermal installations, groundwater management, and well spacing or depth. Specifications are left to vendors whose goals are to achieve specific heating/cooling objectives; potential impacts on the environment are secondary.

通过更多地采用可再生能源来减少对化石燃料的依赖，已成为缓解气候变化和尽量减少温室气体排放的全球优先事项。在加拿大，使用地热供暖（或地源热泵）已成为建筑物供暖和制冷的流行选择，预计在短期内，大多数大型建筑物将包括地热供暖作为其气候控制策略的一部分。然而，人们对地热供暖对地下环境的影响知之甚少。此外，对于地热装置、地下水管理以及井距或深度的规定很少。规格留给那些目标是实现特定加热/冷却目标的供应商；对环境的潜在影响是次要的。
